Description
본 발명은 친환경 침투 방수제에 관한 것으로서, 더욱 상세하게는 바탕면에 도포되는 시멘트 페이스트 및 모르터 사이의 접착성 강화 및 수밀성을 확보하도록 하여 액체방수공법의 제품경쟁력을 강화한 친환경 침투 방수제에 관한 것이다.The present invention relates to an eco-friendly penetrating waterproofing agent, and more particularly, to an eco-friendly penetrating waterproofing agent that strengthens the product competitiveness of the liquid waterproofing method by enhancing the adhesion between the cement paste and the mortar applied to the base surface and securing watertightness.
일반적으로 콘크리트는 방수력이 약하기 때문에 콘크리트 구조체에 대한 수분 침투 및 누수를 방지하기 위하여 방수시공을 하는데, 방수공법은 시멘트를 이용하는 액체방수, 합성고분자를 이용하는 시트방수, 도막방수, 아스팔트방수로 대별할 수 있으며, 특히 시멘트를 이용한 액체방수는 욕실, 베란다, 발코니, 다용도실, 지하실 등에 많이 시공해 왔는데, 시멘트를 이용한 액체방수공법은 투수·흡수에 대한 저항 성능을 가진 액체형 방수제를 시멘트 모르타르 또는 시멘트에 혼합하여 만든 방수 시멘트 모르타르 또는 방수 시멘트 페이스트를 바닥, 벽, 천장을 이루는 콘크리트 구조체 위에 방수층을 시공하여 구조체의 누수를 방지하기 위한 방수공법이다.In general, because concrete has a weak waterproofing power, waterproofing is done to prevent moisture penetration and leakage into the concrete structure. , especially liquid waterproofing using cement has been widely used in bathrooms, verandas, balconies, utility rooms, and basements. It is a waterproofing method to prevent leakage of structures by installing waterproofing cement mortar or waterproofing cement paste on the concrete structures forming floors, walls, and ceilings.
시멘트 액체방수란 콘크리트 구조체의 바탕면에 지방산, 지방산염, 아스팔트 에멀젼, 수용성 수지 등과 같은 유기질계의 방수제와 혼합한 시멘트 모르타르 등을 덧발라 구조체 바탕에 수밀한 유기질 혹은 무기질계 방수층을 형성하는 공법이다. 특히, 시멘트 액체방수공법은 구성재료가 물, 시멘트, 방수액으로 시멘트와 물이 반응하는 특성을 가지고 있기 때문에 습윤하거나 다소의 요철이 있는 바탕면에도 시공이 가능하고 마감이 간단하다는 장점이 있지만, 방수층 자체가 균열이 생기기 쉽다는 단점이 있다.Cement liquid waterproofing is a method of forming a watertight organic or inorganic waterproofing layer on the base of a concrete structure by applying cement mortar mixed with an organic waterproofing agent such as fatty acid, fatty acid salt, asphalt emulsion, and water-soluble resin on the base of the concrete structure. . In particular, the cement liquid waterproofing method has the advantage that it can be installed on a wet or slightly uneven base surface and the finish is simple, because the constituent materials are water, cement, and waterproofing liquid, and the cement and water react. The disadvantage is that it is easy to crack itself.
최근 건축하는 구조물들은 콘크리트 구조체를 양생한 후 거푸집을 떼어내고 나면, 구조체의 표면이 거칠거칠한 것이 아니라 매끈매끈하기 때문에 구조체의 표면에 시멘트 모르타르로 미장 또는 방수층 형성을 위한 방수시공을 하기가 매우 어렵다. 특히, 지금까지 출현한 액체 방수제는 부착력이 약하기 때문에 시멘트 액체방수공법으로 바닥면에 방수시공을 하면 시공 당시에는 방수층이 구조체의 표면에서 떨어지지는 않지만 시공 후에는 방수층이 구조체의 표면에서 박리 또는 들뜸 현상이 잘 발생한다는 문제가 있고, 벽이나 천장에 방수시공을 하면 시멘트 모르타르가 매끈매끈한 구조체의 표면에 붙지 않고 떨어져 버리기 때문에 시공작업에 많은 애로가 있어서, 방수시공을 하기 전에 정이나 망치와 같은 연장으로 매끈매끈한 구조체의 표면에 흠집을 내는 작업을 별도로 하고 있다.In recent structures, after curing the concrete structure and removing the formwork, the surface of the structure is smooth rather than rough. . In particular, since the liquid waterproofing agents that have appeared so far have weak adhesion, when waterproofing the floor with the cement liquid waterproofing method, the waterproofing layer does not come off the surface of the structure at the time of construction, but the waterproofing layer peels off or floats from the surface of the structure after construction. There is a problem that this occurs easily, and when waterproofing a wall or ceiling, the cement mortar does not stick to the smooth surface of the structure and falls off, so there are many difficulties in the construction work. We are working separately to scratch the surface of the smooth structure.
지금까지 침투성 방수제에 대하여 많은 기술이 출현하였는데, 예를 들면, 공개특허 제1992-18161호 침투성 실리콘계 발수제 조성물, 공개특허 제1998-24917호 침투성 물 흡수 방지제, 공개특허 제1999-78673호 실리콘 에멀젼 수용성 발수·방수제의 조성물 및 제조방법, 공개특허 제2001-64300호 침투성 방수제, 공개특허 제2001-93323호 유기용제를 포함하는 알킬알콕시실란계 발수제, 공개특허 제2003-92860호 알킬알콕시실란 및 고분자 화합물을 포함하는 침투성 방수제 등 액체 방수제를 사용하는 방수제 및 시공방법에 대한 기술이 발명 및 등록되었다.Until now, many technologies have appeared for penetrating waterproofing agents, for example, Patent Publication No. 1992-18161 Penetrating Silicone-based Water Repellent Composition, Patent Publication No. 1998-24917 Penetrative Water Absorption Prevention Agent, Patent Publication No. 1999-78673 Silicone Emulsion Water-Soluble Composition and manufacturing method of water repellent/water repellent agent, Patent Publication No. 2001-64300 Penetrating Waterproofing Agent, Korean Patent Publication No. 2001-93323 Alkylalkoxysilane-based water repellent containing organic solvent, Patent Publication No. 2003-92860 Alkylalkoxysilane and polymer compound A technology for a waterproofing agent and a construction method using a liquid waterproofing agent such as a penetrating waterproofing agent containing
하지만, 액체 방수제는 물에 희석하여 사용하므로 분말 형태보다는 분산성이 양호하지만, 대부분이 발수성이 높은 지방산 금속염 용해물을 주재로 하기 때문에 지방산계의 특성상 시멘트와 교반시 다량의 기포가 발생하여 조직이 다공질화 될 우려가 있으며, 시멘트의 수화를 지연시켜 강도저하, 응결지연 현상이 나타나게 되고, 무엇보다도 부착력이 약해서 방수층과 콘크리트 구조체 간 박리 또는 들뜸 현상이 발생할 뿐만 아니라 방수시공된 경화체의 강도와 수밀성 및 부착력을 증진시키기 위하여 경화촉진제, 보수제, 분산제, 지수제, 접착제, 방동제 등과 같은 많은 보조재료를 첨가하여 제조하고 있다.However, since liquid waterproofing agents are used after being diluted with water, they have better dispersibility than powdered ones. However, most of them mainly contain dissolved fatty acid metal salts with high water repellency. There is a risk of becoming porous, and delaying the hydration of cement leads to a decrease in strength and delay in setting, and above all, the weak adhesion causes peeling or lifting between the waterproofing layer and the concrete structure, as well as the strength and watertightness of the waterproofed hardened body and It is manufactured by adding many auxiliary materials such as curing accelerators, water retaining agents, dispersing agents, water-repellent agents, adhesives, and anti-freezing agents to enhance adhesion.
따라서 방수층과 콘크리트 구조체 사이의 부착력이 탁월하여 박리 및 들뜸 현상이 발생하지 않을 뿐만 아니라 모체인 콘크리트 구조체에 형성된 무수히 많은 미세공극으로의 침투능력이 탁월하여 방수성능도 뛰어난 액상 방수제에 대한 연구가 필요한 시점이다.Therefore, it is necessary to study a liquid waterproofing agent with excellent waterproof performance due to its excellent adhesion between the waterproofing layer and the concrete structure, so that peeling and lifting does not occur, as well as penetrating into countless micropores formed in the concrete structure, which is the parent. am.
본 발명은 상기와 같은 필요에 의해 안출된 것으로, 본 발명의 목적은, 콘크리트 구조체 표면에 미장 또는 도포하여 방수층을 형성하기 위하여 시멘트 모르타르 또는 시멘트 페이스트에 혼합하여 사용함으로써, 시멘트와의 혼합성 및 감수효과와 강도증진에 기여하고, 콘크리트면의 미세공극에 침투하여 부착력과 방수성을 현저하게 향상시킬 수 있는 침투성 액체 방수제와 방수시공 공정을 단순화하여 작업이 복잡하지 않고 간편하며, 숙련공이 아니라도 쉽게 고품질의 방수시공을 할 수 있는 침투성 액체 방수제를 사용하는 방수공법을 제공하기 위한 것이다.The present invention has been devised for the needs as described above, and an object of the present invention is to mix and use cement mortar or cement paste to form a waterproofing layer by plastering or applying it to the surface of a concrete structure, thereby improving the compatibility and water reduction with cement.

It is to provide a waterproofing method using a permeable liquid waterproofing agent capable of waterproofing.

자기치유재료란 크랙 등과 같은 손상을 치료할 수 있는 능력을 발휘하도록 구조적, 화학적으로 개질시킨 재료를 포함한다. 크랙과 다른 종류의 손상이 미세한 수준으로 발생하면 열적, 전기적, 음양학적 성질이 변하고, 결과적으로 재료 전체의 파단에까지 이르게 할 수 있다.Self-healing materials include materials that have been structurally and chemically modified to exhibit the ability to heal damage such as cracks. When cracks and other types of damage occur on a microscopic level, their thermal, electrical, and yin-yang properties can change, which can lead to the failure of the entire material.
금속의 자기치유는 금속이 갖는 고유의 특성으로 인하여 느리게 진행된다. 즉, 치유제가 금속과 강하게 결합되어 있으며, 그 양도 극히 작다. 일반적으로 금속에서 발생하는 결함의 자기치유는 결함이 일어난 곳에 석출물을 형성시키고, 이 석출물이 파단에 이르도록 하는 결함의 성장을 막는 방법으로 치유한다. 매트릭스에 과포화 상태로 용해되어 있거나, 내부 층에 석출된 용질 원자인 치유제의 유동성은 유기재료에서와는 달리 금속에서는 극히 떨어진다. 심지어는 용융점 근처의 온도에서도 확산 속도가 높지 않아 극히 작은 양만이 작은 거리로 이동된다. 이런 이유로 금속에서의 자기치유는 상대적으로 높은 온도에서 조작되고, 결함의 형성 속도가 느린 계에 국한되는 경우가 많다. 결함이 클 경우 많은 양의 치유제가 급히 필요하기 때문에 금속의 자기치유 공정은 나노 규모 결함에서 가장 효과적이다.The self-healing of metals proceeds slowly due to the intrinsic properties of metals. That is, the healing agent is strongly bound to the metal, and the amount is very small. In general, self-healing of defects occurring in metals is cured by forming precipitates where the defects occur, and preventing the growth of defects that lead to fractures. The fluidity of the healing agent, which is a solute atom dissolved in a supersaturated state in the matrix or precipitated in the inner layer, is extremely poor in metals, unlike in organic materials. Even at temperatures near the melting point, the diffusion rate is not high, so only a small amount is transported over a small distance. For this reason, self-healing in metals is often limited to systems that operate at relatively high temperatures and have a slow rate of defect formation. The self-healing process of metals is most effective for nanoscale defects because large amounts of healing agents are urgently needed when the defects are large.
세라믹과 관련하여, 균열 치유 메커니즘은 (1) 재소결, (2) 인장 잔류응력 완화, (3) 산화에 의한 균열 봉합으로 나눌 수 있다. 확산형 균열치유공정인 재소결은 일차 균열의 분해로 시작된다. 이와 같은 퇴행은 크랙 팁 근처에 규칙 배열의 실린더형 공동을 발생시킨다. 단결정 및 다결정 세라믹에서 확산형 균열 치유 모델과 속도론이 제안되기도 하였다. 그러나 고온에서만 결정입자의 성장이 일어나는 단점이 있다. 균열 치유로 상당한 강도의 회복을 기대할 수 있지만, 열처리 후에도 강도가 감소되는 경우가 많다. 침해 받은 자리에서 인장 잔류응력이 완화되면 강도가 회복된다. 산화에 의한 균열치유에 필요한 열처리온도는 재소결에 의한 균열치유에 필요한 온도보다 낮다. 균열이 형성된 산화물에 의해 치유된다는 점도 매우 중요하다. Regarding ceramics, crack healing mechanism can be divided into (1) re-sintering, (2) tensile residual stress relaxation, and (3) crack sealing by oxidation. Resintering, a diffusion type crack healing process, begins with the decomposition of the primary crack. This degeneration results in a regular arrangement of cylindrical cavities near the crack tip. Diffusion crack healing models and kinetics have also been proposed in monocrystalline and polycrystalline ceramics. However, there is a disadvantage that crystal grain growth occurs only at high temperatures. Although a significant recovery of strength can be expected with crack healing, the strength is often reduced even after heat treatment. When the tensile residual stress is relieved at the damaged site, the strength is restored. The heat treatment temperature required for crack healing by oxidation is lower than the temperature required for crack healing by re-sintering. It is also very important that the cracks are healed by the oxide formed.
콘크리트는 분류상 세라믹 재료에 해당하지만 자기치유성이 무엇보다도 필요하다. 균열에 침투된 물과 반응하면 수화과정을 거쳐, 발생된 균열이 일부 혹은 완전히 치유될 수 있기 때문이다. Concrete is classified as a ceramic material, but self-healing properties are required above all else. This is because, when it reacts with water penetrating into the crack, it undergoes a hydration process, and the generated crack can be partially or completely healed.
콘크리트는 지구상에서 가장 널리 사용되고 있는 건축 재료이며, 매년 1인당 2.5톤(1m3 이상)의 콘크리트를 제조하기 위해 시멘트가 사용되고 있다. PC와 물을 반응시키면 수화 제품이 얻어지며, 이것이 시멘트 입자를 접합시켜, 단단한 시멘트 덩어리가 되도록 한다. 시멘트와 물을 모래와 혼합하면 몰타르가 얻어진다. 이 혼합물은 거친 집합체를 함유하고 있으며, 이를 콘크리트라 부른다. 이것은 취성 재료이고, 압축에 의해 강해지지만, 인장에는 약한 성질을 보인다. 전통적 콘크리트의 압축강도는 20 내지 60 MPa이다. 수분 대 시멘트 비를 낮게 하면 입자 패킹을 향상시킬 수 있으며, 특수 첨가제를 사용 100 내지 200 MPa에 이르는 높은 강도의 시멘트도 만들 수 있다. 시멘트 기초 복합체도 설계할 수 있으며, 압축강도가 800 MPa에 이르는 것도 설계할 수 있다. 그러나, 구부림과 인장력이 가해지면 시멘트는 쉽게 손상되기 때문에 보강이 필요하다. 시멘트의 보강을 수동적인 방법으로 할 경우 콘크리트에 균열이 발생하면 활성화된다. 사실 균열의 형성은 보강 시멘트 고유의 특징이기 때문에 보강 콘크리트 구조에서 균열은 손상이나 파괴로 여기지 않으며, 균열이 안전에 문제를 일으키지 않을 수도 있다. 그러나, 균열 너비는 설계된 균열 너비 한계를 넘지 말아야 한다. 균열이 지나치게 넓으면, 콘크리트가 보강제로 사용되는 강철의 부식을 방지할 수 있는 용량을 넘어설 수도 있기 때문이다. 보강 강철의 부식은 콘크리트 구조의 조기 파괴의 중요한 원인의 하나이다. 이와 같은 거대 균열 외에도 시멘트 덩어리의 수축변형 등의 이유로 기지 재료 내에 미세 균열을 발생시킬 수도 있다. 미세 균열은 콘크리트에서 일반적으로 발생하며, 막을 수 도 없다. 미세 균열이 모여 연속 네트워크를 형성하면 콘크리트의 투수성에 큰 영향을 미치게 되고, 침해성 물질의 침투에 대한 저항성이 급감하게 된다.Concrete is the most widely used building material on the planet, and cement is used to manufacture 2.5 tons (more than 1 m 3 ) of concrete per person per year. When PC and water are reacted, a hydration product is obtained, which bonds cement particles to form a solid mass of cement. When cement and water are mixed with sand, a mortar is obtained. This mixture contains coarse aggregates, which are called concrete. It is a brittle material and becomes strong in compression, but weak in tension. The compressive strength of conventional concrete is 20 to 60 MPa. A lower moisture-to-cement ratio can improve particle packing, and with special additives, high-strength cements ranging from 100 to 200 MPa can be made. Cement base composites can be designed, and compressive strengths up to 800 MPa can be designed. However, when bending and tensile forces are applied, cement is easily damaged and therefore needs reinforcement. In the case of passive reinforcement of cement, it is activated when cracks occur in the concrete. In fact, since the formation of cracks is an inherent characteristic of reinforcing cement, cracks in reinforced concrete structures are not considered damage or destruction, and cracks may not pose a safety problem. However, the crack width should not exceed the designed crack width limit. If the cracks are too wide, the concrete may exceed the corrosion protection capacity of the steel used as reinforcement. Corrosion of reinforcing steel is one of the important causes of premature failure of concrete structures. In addition to these macrocracks, microcracks may occur in the matrix material due to shrinkage deformation of the cement mass, etc. Microcracks are common in concrete and cannot be prevented. When microcracks gather to form a continuous network, the water permeability of concrete is greatly affected, and the resistance to penetration of invasive substances decreases sharply.
콘크리트 자가 치유제는 정제수 10 내지 30 중량부, 규산나트륨 35 내지 40 중량부 및 실란계 수용액 100 내지 120 중량부를 포함할 수 있다.The concrete self-healing agent may include 10 to 30 parts by weight of purified water, 35 to 40 parts by weight of sodium silicate, and 100 to 120 parts by weight of a silane-based aqueous solution.
콘크리트에 내재된 수산화 칼슘과 크리트 자가 치유제가 반응하여 C-S-H계의 백색 결정이 생성되어 생성물이 균열 부위에 충진되어 조직을 치밀화시킬 수 있다.Calcium hydroxide inherent in concrete reacts with the crete self-healing agent to form C-S-H white crystals, and the product can fill the cracks and densify the tissue.
규산나트륨은 콘크리트 구조물에 내재된 수산화 칼슘(Ca(OH)2)와 반응하여 C-S-H계의 결정(젤 상태의 무기폴리머)을 생성하게 되어 균열 부분을 충진시키기 위해 포함되는 물질이다. 규산나트륨 수용액은 마감액을 끌고 들어가 충진, 치밀화를 촉진하기 때문에 자가복귀 기능을 수행하게 되어 매우 건실하고 안정적이면서 높은 방수성, 높은 인장강도와 압축강도를 유지하여 내구성을 높이게 되고, 나아가 중성화억제 및 방청기능 강화로 콘크리트 구조물의 장수명화를 달성하게 된다. 콜로이드질 규산나트륨계 함침재는 수용액 상태에서 사슬 형태의 분자가 나트륨 원자에 둘러쌓여 있는 구조를 가지는 폴리 실리게이트 구조로 존재한다. 이러한 폴리 실리게이트 구조(약 50㎛)는 규산나트륨이온(약 30㎛)의 집합체보다 크나, 나노사이즈 형태의 규산나트륨은 약 1 내지 2nm정도로 작기 때문에, 콜로이드질 규산나트륨계함침재와 비교하였을 때 침투속도, 침투깊이, 반응속도 등이 더 우수하며, 방수성능에서도 차이가 있다.Sodium silicate reacts with calcium hydroxide (Ca(OH) 2 ) inherent in the concrete structure to form CSH-based crystals (gel-state inorganic polymer), and is included to fill cracks. Sodium silicate aqueous solution attracts the finishing liquid and promotes filling and densification, so it performs a self-recovery function, so it is very sturdy and stable, and it maintains high waterproofness, high tensile and compressive strength to increase durability. Longer lifespan of concrete structures is achieved through functional reinforcement. The colloidal sodium silicate-based impregnating material exists as a polysilicate structure having a structure in which chain molecules are surrounded by sodium atoms in an aqueous solution state. This polysilicate structure (about 50 μm) is larger than the aggregate of sodium silicate ions (about 30 μm), but the nano-sized sodium silicate is as small as about 1 to 2 nm, when compared with colloidal sodium silicate-based impregnating materials Penetration speed, penetration depth, reaction speed, etc. are superior, and there is a difference in waterproofing performance.
실란계 수용액은 표면 보호제로 작용한다.The silane-based aqueous solution acts as a surface protectant.
