Description
본 발명은 콘크리트의 양생시 사용되는 수용성 이형제의 제조방법에 관한 것이다.The present invention relates to a method for producing a water-soluble release agent used in curing of concrete.
산업이 발달함에 따라 각종 공사에 양생 완료된 콘크리트가 많이 쓰이고 있으며, 현장에서 직접 몰드나 패널, 폼등에 의한 양생도 더욱 증가하게 되었다. 이에 따라 이러한 양생에 주로 쓰이는 몰드나 패널, 폼등에 사용되는 이형제 또한 과거에 비해 중요하게 되었다.As the industry develops, a lot of cured concrete is used in various constructions, and the curing by molds, panels, foams, etc. has been increased in the field. Accordingly, release agents used in molds, panels, and foams, which are mainly used for curing, have become more important than in the past.
일반적으로 이형제는 유용성 이형제와 수용성 이형제가 있으며 유용성 이형제에는 광유계에 로진, 왁스, 오일, 고분자등을 섞어 사용한 것이 대부분이며 수용성 이형제는 비누, 왁스, 계면활성제, 고분자등을 물에 분산시켜 사용하는 것이 일반적이다.In general, mold release agents include oil-soluble mold release agents and water-soluble release agents, and oil-soluble release agents are mostly used by mixing rosin, wax, oil, and polymers in mineral oils. Is common.
최근에는 환경의 중요성으로 광유계의 사용이 점차 제한되어지고 있고, 특히 원심관, 흄관, 파일등을 양생하여 판매하는 회사들의 작업장 환경이 중요시 되고 있어 수용성 이형제로의 전환을 신경쓰고 있다. 특히, 건물, 다리, 고속전철등의 현장에서 양생시 사용되는 오일이나 광유계 이형제는 공사장 주변의 토양이나, 하천, 강 등을 오염시켜 환경에 나쁜영향을 주게 되는 원인이 되고 있다.Recently, due to the importance of the environment, the use of mineral oils is gradually limited, in particular, the workplace environment of companies that cure and sell centrifuge tubes, fume tubes, piles, etc. is becoming important, so the conversion to a water soluble release agent is concerned. In particular, the oil or mineral oil release agent used in curing, such as buildings, bridges, high-speed trains, such as contamination of the soil, rivers, rivers, etc. around the construction site is causing a bad effect on the environment.
이러한 필요성에 의하여 점차 수용성 이형제의 사용이 증가되고 있는 추세에 있다.Due to this necessity, the use of water-soluble release agents is gradually increasing.
그러나, 종래의 수용성 이형제는 비누, 왁스, 계면활성제, 고분자 등을 단독 또는 혼용으로 물에 분산시켜 사용하고 있기 때문에 유용성 이형제에 비하여 안정성이 떨어지고, 스팀양생이나 진동하는 물체를 양생하는 경우 피막이 약하여 이형효과가 없어지는 단점이 있었다.However, since conventional water-soluble release agents are used by dispersing soap, wax, surfactants, polymers, etc. in water alone or in combination, they are less stable than useful release agents, and when the film cures steam or vibrates, the film is weak. There was a disadvantage that the effect is lost.
또한 도포후 내후성 및 발수성이 약하여 이형제 도포후 장기간 작업이 필요한 다리나 고속철도 공사의 경우에는 자외선과 우천으로 인하여 이형제 피막이 쉽게 손상되므로 사용에 따른 많은 제한이 따랐다.In addition, since the weather resistance and water repellency after the application of the release agent is required for a long time after the application of the bridge or high-speed railway construction, the release agent film is easily damaged due to ultraviolet rays and rainy weather, so many restrictions have been followed.
이러한 단점들을 보완하기 위하여 수용성 이형제에 다량의 광유기나 오일기가 함유된 제품들이 사용되고 있어 사실상 완전한 수용성 이형제라고 할 수 없었고, 특히 터널이나 밀폐된 곳에서 발화가 우려될 정도로 유용성에 가까운 제품이 대부분이었다.In order to make up for these drawbacks, products containing a large amount of mineral or oil groups in water-soluble mold release agents were used, and thus, in fact, they were not completely water-soluble release agents.
본 발명은 이와같은 문제점을 해결하기 위한 것으로, 본 발명의 목적은, 환경오염이 없고, 범용적으로 사용될 수 있는 수용성 이형제의 제조방법을 제공하고자 하는 것이다.The present invention has been made to solve such a problem, and an object of the present invention is to provide a method for preparing a water-soluble releasing agent that can be used in general without environmental pollution.
다른 목적은, 내구성 및 방수성에 있어 이형제 코팅 후 자외선 및 빗물에도 오랜기간 코팅막을 유지할 수 있는 수용성 이형제의 제조방법을 제공하고자 하는 것이다.Another object of the present invention is to provide a method for preparing a water-soluble releasing agent that can maintain a coating film for a long time in UV and rain water after coating a releasing agent in durability and waterproofness.
이와 같은 목적은 왁스와 금속비누를 1:0.1에서 0.1:1까지 혼합한 분산체 100wt%를 첨가한 수용성 이형제로서 달성할 수가 있다.This object can be achieved as a water-soluble releasing agent to which 100 wt% of a dispersion in which wax and metal soap are mixed from 1: 0.1 to 0.1: 1 is added.
특히 이와 같은 수용성 이형제에 지방산아민치환체를 치환시키거나, 지방산아민 치환후 각종 방부제, 산화방지제, 계면활성제 등을 소량 첨가하여 달성시킬 수가 있다.In particular, such a water-soluble releasing agent can be achieved by substituting a fatty acid amine substituent or by adding a small amount of various preservatives, antioxidants, surfactants and the like after fatty acid amine substitution.
이하 본 발명의 수용성 이형제의 제조방법을 구체적인 실시예로서 상세히 설명하면 다음과 같다.Hereinafter, a method for preparing a water-soluble release agent of the present invention will be described in detail as specific examples.
일반적인 콘크리트의 양생시 범용적으로 사용할 수 있는 우수한 수용성 이형제의 제조를 위하여 왁스와 금속비누를 1:0.1에서 0.1:1까지 혼합한 분산체 100wt%를 첨가한 새로운 수용성 이형제의 개발에 그 주안점을 두었다.In order to manufacture excellent water-soluble release agent that can be used universally in curing of concrete, the emphasis was on the development of a new water-soluble release agent containing 100 wt% of a dispersion in which wax and metal soap were mixed from 1: 0.1 to 0.1: 1. .
여기서 사용된 왁스의 종류에는 PE, 파라핀, 아마이드왁스 등이며 사용된 금속비누의 종류에는 C5~C25의 포화 또는 불포화 지방산에 Li, Zn, Al, Ca, Mg, Co, Cu, Ti, Na, Zr, K, Ba, Mn, Sn등이 치환된 염화물이고, 사용된 지방산아미치환체는 지방산에 트리에틸렌테트라아민, 디에틸렌트리아민, 테트라에틸렌펜타아민 등을 치환시킨 것을 사용하고 있다.The type of wax used here is PE, paraffin, amide wax, etc. The type of metal soap used is Li, Zn, Al, Ca, Mg, Co, Cu, Ti, Na, Zr to C5 ~ C25 saturated or unsaturated fatty acid. , K, Ba, Mn, Sn and the like are substituted chlorides, and the fatty acid amino substituents used are those obtained by substituting triethylenetetraamine, diethylenetriamine, tetraethylenepentaamine, and the like into fatty acids.
상기 지방산아민치환체의 사용유무에 따라 실시한 각각의 실시예 1, 2의 특성은 다음과 같다.The characteristics of each of Examples 1 and 2 performed according to the use of the fatty acid amine substituent are as follows.
[실시예 1]Example 1
파라핀왁스와 칼슘-스테아레이트(Calcium-Stearate)가 1:1로 혼합된 분산체(고형분 30%) 100wt%에 올레인산트리에틸렌 테트라아민치환체 5wt%를 혼합하여 생성물1을 얻었다. 생성물1에 다음과 같은 시험방법으로 이형실험을 실시하여 표1과 같은 결과를 얻었다.Product 1 was obtained by mixing 5 wt% of triethylene tetraamine tetraamine oleate with 100 wt% of a dispersion (solid content 30%) in which paraffin wax and calcium-stearate were mixed in a 1: 1 ratio. The product 1 was subjected to a release test by the following test method to obtain the results shown in Table 1.
[시험방법][Test Methods]
시험체 성형용 틀은 KSL 5105(수경성 시멘트 모르터 압축강도 시험방법) 2.4의 시험체 성형용 틀을 이용한다. 콘크리트 이형제를 성형틀 벽면에 골고루 도포한 다음 KSL 5201(포틀랜드 시멘트)에 규정한 보통 포트랜드 시멘트와 KSL 5001(표준사)에 규정한 모래와 물을 1:2.45:0.48 중량비로 배합하여 성형틀에 넣고 KSL5105 9항의 시험체 성형방법에 따라 시험체를 성형한 다음 상온 상습에서 48시간동안 양생시킨 다음 탈형하여 시험체로 한다. 시험체는 3개를 탈형한다.For the test mold shaping, the test mold for the test specimen of KSL 5105 (hydraulic cement mortar compressive strength test method) 2.4 shall be used. Apply the concrete release agent evenly to the wall of the mold, and then mix the ordinary portland cement specified in KSL 5201 (Portland Cement) with sand and water specified in KSL 5001 (Standard Yarn) at a weight ratio of 1: 2.45: 0.48 and place it in the mold. The test body shall be molded according to the test method of KSL5105 Clause 9, cured for 48 hours at room temperature and humidity, and then demolded. Test specimens are demolded three.
[실시예 2]Example 2
파라핀왁스와 Zinc-Stearate가 3:1로 혼합된 분산체(고형분 20%) 100wt%에 팔미틱산트리에틸렌테트라아민 치환체 8wt%를 혼합하여 생성물2를 얻었다. 생성물 2를 (실시예 1)과 동일한 시험방법으로 이형시험을 실시하여 표 2와 같은 결과를 얻었다.Product 2 was obtained by mixing 8 wt% of palmitic acid triethylenetetraamine substituent in 100 wt% of a dispersion (20% solids) in which paraffin wax and Zinc-Stearate were mixed 3: 1. Product 2 was subjected to a release test using the same test method as in (Example 1) to obtain the results shown in Table 2.
이와 같이 수용성 이형제중 일반적인 왁스만을 사용하거나 계면 활성제 또는 고분자 등을 혼합하여 사용하였을 경우에는 피막의 강도가 약하여 이형제의 도포후 장기간 보존이나 진동, 스팀양생에서는 효과적인 이형을 할 수 없으나, 본 발명의 실시예에서와 같이 금속비누와 지방산아민 치환체를 넣어주면 피막의 강도가 보다 우수해짐을 알 수 있는 것으로 실시예 1에서는 금속비누로서 피막의 강도를 높일 수가 있으며, 실시예 2에서는 금속비누와 함께 지방산아민치환체를 사용하여 보다 높은 피막의 강도를 얻을 수가 있었다.As such, when only general waxes of water-soluble mold release agents are used or surfactants or polymers are mixed and used, the strength of the film is weak, so that effective release is not possible during long-term storage, vibration, or steam curing after the release of the release agent. As in the example, the addition of the metal soap and the fatty acid amine substituent showed that the coating strength was better. In Example 1, the strength of the coating film was increased as the metal soap. In Example 2, the fatty acid amine was added together with the metal soap. Using a substituent, higher film strength could be obtained.
또한 다른 실시예로서 왁스와 금속비누를 1:0.1에서 0.1:1까지 혼합한 분산체 100wt%(고형분 10~50)에 지방산아민치환체를 0.1~50wt% 첨가한 수용성 이형제에 각종 방부제, 산화방지제, 계면활성제 등을 소량 첨가할 수도 있다.In another embodiment, various preservatives, antioxidants, and the like in a water-soluble releasing agent in which 0.1 to 50 wt% of a fatty acid amine substituent is added to 100 wt% (solid content of 10 to 50) of a dispersion in which wax and metal soap are mixed from 1: 0.1 to 0.1: 1. A small amount of surfactant may be added.
이때 사용되는 각종 방부제, 산화방지제, 계면활성제 등은 기존의 수용성 이형제에서도 널리 사용되고 있는 재료로서 콘크리트의 이형공정시 주변사항의 조건에 따라 가감하여 사용할 수 있는 것은 물론이다.At this time, various preservatives, antioxidants, surfactants, etc. are widely used in existing water-soluble release agents, of course, can be used depending on the conditions of the ambient conditions during the release process of concrete.
이상에서와 같이 본 발명은 완전한 수용성 이형제로 유용성 이형제에서 생기는 기름곰보의 발생이 없고 오일에 의한 오일때가 남지 않으며, 몰드의 원형보존이 가능하여 세척없이 반복사용이 가능할 뿐 아니라, 내구성 및 방수성이 있어 이형제 코팅 후 자외선 및 빗물에도 오랜기간 코팅막을 유지하여 현장에서 이형제를 도포한 후, 장기간의 작업을 요하는 곳에서도 유용하게 사용될 수 있다.As described above, the present invention is a complete water-soluble releasing agent, there is no occurrence of grease occurring in the soluble releasing agent, no oil stains due to the oil, and the preservation of the mold is possible. After coating the release agent in the field by maintaining the coating film for a long time even in the ultraviolet and rain water, it can be usefully used even in places requiring long-term work.
본 발명은 실 사용예로서, 원심, 파일과 건축용 벽체 등의 Pre-cast Concrete의 몰드에 도포하여 유용하게 사용할 수 있으며, 건축 및 토목공사장의 패널, 새들등의 표면에 도포시 어느 조건의 양생에서도 쉽게 이형이 가능하다. 뿐만아니라 유용성 이형제에서는 녹는 스티렌폼으로 만든 용벽용 무늬판에서 본 발명의 수용성 이형제를 사용하면 깨끗하게 표면을 유지하면서 이형이 용이하게 되어 작업성이 향상되게 된다. 특히 우수한 내구성과 방수성으로 다리나, 고속철도의 대형구조물의 양생시 이형제 도포후 오랜시간 철근작업을 요하는 곳에는 매우 유용하다.The present invention is a practical use example, it can be usefully applied to the mold of pre-cast concrete, such as centrifugal, pile and building walls, and even in curing under any conditions when applied to the surface of panels, saddles, etc. Easily released. In addition, in the oil-soluble release agent, using the water-soluble release agent of the present invention in the molten styrene foam patterned plate made of styrene foam is easy to release while maintaining a clean surface is improved workability. Especially, it is very useful in the place where reinforcement work is required for a long time after application of release agent when curing bridge or high-speed railway large structures due to its excellent durability and waterproofness.
