Description
본 발명은 개량된 탄약 보관용 지환통에 관한 것으로, 보다 상세하게는 종이를 사용하여 지환통을 제조함으로써 재생 및 파기가 용이하되 강도는 우수하고 친환경적이면서 특히, 습기차단력이 뛰어나 탄약을 보다 안전하게 보관 유지할 수 있도록 한, 개선된 개량된 탄약 보관용 지환통에 관한 것이다.The present invention relates to an improved ammunition storage ring container, and more specifically, to an improved ammunition storage ring container which is manufactured using paper, so that the ring container is easy to recycle and destroy, yet has excellent strength and is environmentally friendly, and in particular, has excellent moisture-blocking properties, so that ammunition can be stored more safely.
일반적으로 탄약 및 수류탄 등의 폭발물은 그 특성상 습기에 취약한 성질을 가지고 있다. 이러한 특성에 따라 수분 또는 습기 등의 외부요인으로부터 탄약 및 수류탄 등을 보호하기 위해, 방습기능을 구비하는 포장용 용기가 사용되고 있다.In general, explosives such as ammunition and grenades are vulnerable to moisture due to their nature. In order to protect ammunition and grenades from external factors such as moisture or humidity, packaging containers with moisture-proof functions are used.
또한, 이동 및 포장을 위해, 가벼운 소재로 만들어지는 포장용 용기가 절대적으로 필요하여, 통상적으로는 지관을 활용한 포장용기가 많이 사용되고 있다.In addition, for transportation and packaging, packaging containers made of lightweight materials are absolutely necessary, and packaging containers using tubes are commonly used.
이와 같은 지관용기는 외부습기 등의 요인으로부터 내용물을 보호하기 위해, 다양한 처리방법을 사용한 지관을 이용하여 용기를 제작하게 된다.To protect the contents from external moisture and other factors, containers are made using tubes that have been treated with various methods.
그 대표적인 예로 아스팔트콜타르를 종이에 함침시켜 외부습기 등을 1차로 차단하고, 알루미늄 박 또는 비닐 등의 2차적인 수단으로 정전기 또는 외부습기 등을 차단하게 된다.A typical example is to impregnate paper with asphalt tar to block external moisture, and then use a secondary means such as aluminum foil or vinyl to block static electricity or external moisture.
그런데, 아스팔트콜타르는 환경규제물질로서 사용하기 어렵다.However, asphalt coal tar is difficult to use as an environmentally regulated substance.
이에, 최근에는 파라핀을 사용하고 있으나, 파라핀은 습기 차단능력이 뛰어나지 못해 이에 대한 개선을 요구하고 있는 실정이다.Accordingly, paraffin has been used recently, but paraffin does not have excellent moisture blocking ability, and there is a demand for improvement in this regard.
이를 부응하기 위해, 본 출원인은 등록특허 제10-2545824호(2023년06월15일) 탄약 보관용 지환통(Type V)을 특허 등록받은 바 있다.To meet this need, the applicant has been granted a patent for a cartridge case (Type V) for ammunition storage under the registered patent no. 10-2545824 (June 15, 2023).

본 발명 설명에 앞서, 이하의 특정한 구조 내지 기능적 설명들은 단지 본 발명의 개념에 따른 실시예를 설명하기 위한 목적으로 예시된 것으로, 본 발명의 개념에 따른 실시예들은 다양한 형태로 실시될 수 있으며, 본 명세서에 설명된 실시예들에 한정되는 것으로 해석되어서는 아니된다.Before describing the present invention, the following specific structural and functional descriptions are merely exemplified for the purpose of explaining embodiments according to the concept of the present invention, and the embodiments according to the concept of the present invention can be implemented in various forms and should not be construed as being limited to the embodiments described in this specification.
본 발명에 따른 개량된 탄약 보관용 지환통은 도 1의 예시와 같이, 외부통(100)과, 상기 외부통(100) 내부에 삽입된 상태로 접착고정된 내부통(200)을 포함하고, 상기 내부통(200)의 상단 일부는 외부통(100)으로부터 돌출되어 뚜겅(미도시)이 결합되도록 구성된다.An improved ammunition storage ring container according to the present invention comprises an outer container (100) and an inner container (200) that is inserted and fixed into the outer container (100) as shown in the example of Fig. 1, and an upper portion of the inner container (200) is configured to protrude from the outer container (100) and be coupled with a lid (not shown).
도 2에 도시된 본 발명 제1실시예에 따른 외부통(100)은 폴리코트(140)와, 상기 폴리코트(140)의 상면에 합지된 제1알루미늄호일(130)과, 상기 제1알루미늄호일(130)의 상면에 합지된 제1폴리램(120)과, 상기 제1폴리램(120)의 상면에 합지된 제2알루미늄호일(130')과, 상기 제2알루미늄호일(130')의 상면에 합지된 제2폴리램(120')과, 상기 제2폴리램(120')의 상면에 합지된 상부판지(110)를 포함한다.The outer tube (100) according to the first embodiment of the present invention illustrated in FIG. 2 includes a polycoat (140), a first aluminum foil (130) laminated to the upper surface of the polycoat (140), a first polylam (120) laminated to the upper surface of the first aluminum foil (130), a second aluminum foil (130') laminated to the upper surface of the first polylam (120), a second polylam (120') laminated to the upper surface of the second aluminum foil (130'), and an upper board (110) laminated to the upper surface of the second polylam (120').
여기에서, 상기 폴리코트(140)는 크라프트지에 폴리올레핀수지가 접착되어 합지된 형태로서, 특히 바람직하기로는 크라프트지에 폴리올레핀수지 중에서 저밀도폴리에틸렌(LDPE)이 접착되어 합지된 형태를 가짐이 바람직하다. 더욱 바람직하기로는 크라프트지의 내열저항성, 내마모성, 내응력균열성, 내수성을 더 증대시키기 위해 LDPE 대신에 XLPE(Cross Linking-Polyethylene)를 사용할 수도 있다.Here, the polycoat (140) is in the form of a laminated polyolefin resin bonded to kraft paper, and particularly preferably, it is in the form of a laminated low-density polyethylene (LDPE) among polyolefin resins bonded to kraft paper. More preferably, XLPE (Cross Linking-Polyethylene) may be used instead of LDPE to further increase the heat resistance, wear resistance, stress crack resistance, and water resistance of the kraft paper.
여기서, 상기 저밀도폴리에틸렌은 29.6g/㎡∼44.4g/㎡을 유지하고, 상기 크라프트지는 103.6g/㎡∼130.6g/㎡을 유지하도록 구성된다.Here, the low-density polyethylene is configured to maintain 29.6 g/㎡ to 44.4 g/㎡, and the kraft paper is configured to maintain 103.6 g/㎡ to 130.6 g/㎡.
아울러, 상기 제1,2알루미늄호일(130,130')은 지환통이 습기로부터 강한 내습성, 내광성, 밀보성 및 내산화성과 내열성을 확보하기 위해 구비된다.In addition, the first and second aluminum foils (130, 130') are provided to ensure that the ring tube has strong moisture resistance, light resistance, sealing properties, oxidation resistance, and heat resistance.
특히, 이를 위해 상기 제1,2알루미늄호일(130,130')은 0.0254mm~0.0304mm의 두께를 갖도록 구성되어야 하고, 최대 파열강도가 45psi인 템퍼링으로 부분적인 어닐링처리되어야 한다.In particular, for this purpose, the first and second aluminum foils (130, 130') should be configured to have a thickness of 0.0254 mm to 0.0304 mm and should be partially annealed with tempering having a maximum burst strength of 45 psi.
그리고, 상기 제1폴리램(120)과 제2폴리램(120')은 저밀도폴리에틸렌을 사이에 두고 위 아래에 각각 크라프트지가 접착되어 합지된 형태, 즉 상부 크라프트지-저밀도폴리에틸렌-하부 크라프트지의 레이어를 갖도록 구성된다.And, the first polylam (120) and the second polylam (120') are configured to have layers of upper kraft paper-low density polyethylene-lower kraft paper, with kraft paper bonded to the upper and lower portions, respectively, with low density polyethylene in between.
이때에도 각 구성요소들의 중량이 매우 중요한데, 상부 크라프트지는 59.2g/㎡∼66.6g/㎡을 유지하고, 저밀도폴리에틸렌은 20.7g/㎡∼41.44g/㎡을 유지하며, 하부 크라프트지는 103.6g/㎡∼111.0g/㎡을 유지하도록 구성되어야 한다.Even at this time, the weight of each component is very important; the upper kraft paper should be maintained at 59.2 g/㎡∼66.6 g/㎡, the low-density polyethylene should be maintained at 20.7 g/㎡∼41.44 g/㎡, and the lower kraft paper should be configured to be maintained at 103.6 g/㎡∼111.0 g/㎡.
아울러, 본 발명에서 사용되는 저밀도폴리에틸렌(LDPE)은 흑색을 사용한다.In addition, the low-density polyethylene (LDPE) used in the present invention is black.
또한, 상기 상부판지(110)는 크라프트지로서, 중량은 60.0g/㎡∼65.0g/㎡을 유지해야 한다.In addition, the upper board (110) is made of kraft paper and must have a weight of 60.0 g/㎡ to 65.0 g/㎡.
한편, 본 발명에서는 다른 실시예로 상기 외부통(100)을 도 3과 같은 제2실시예 형태로 구성할 수도 있다.Meanwhile, in the present invention, as another embodiment, the outer tube (100) may be configured in the form of the second embodiment as shown in FIG. 3.
도 3에 도시된 본 발명 제2실시예에 따른 외부통(100)은 폴리코트(140)와, 상기 폴리코트(140)의 상면에 합지된 하부판지(150)와, 상기 하부판지(150)의 상면에 합지된 제1알루미늄호일(130)과, 상기 제1알루미늄호일(130)의 상면에 합지된 제1폴리램(120)과, 상기 제1폴리램(120)의 상면에 합지된 제2알루미늄호일(130')과, 상기 제2알루미늄호일(130')의 상면에 합지된 제2폴리램(120')과, 상기 제2폴리램(120')의 상면에 합지된 상부판지(110)를 포함할 수 있다.The outer tube (100) according to the second embodiment of the present invention illustrated in FIG. 3 may include a polycoat (140), a lower board (150) laminated to the upper surface of the polycoat (140), a first aluminum foil (130) laminated to the upper surface of the lower board (150), a first polylam (120) laminated to the upper surface of the first aluminum foil (130), a second aluminum foil (130') laminated to the upper surface of the first polylam (120), a second polylam (120') laminated to the upper surface of the second aluminum foil (130'), and an upper board (110) laminated to the upper surface of the second polylam (120').
이때, 상기 하부판지(150)도 앞서 설명한 상부판지(110)와 동일한 크라프트지이며, 중량도 동일 범위이다.At this time, the lower cardboard (150) is also the same kraft paper as the upper cardboard (110) described above, and the weight is also in the same range.
특히, 상기 하부판지(150)는 폴리코트(140)를 지지하는 지지력을 보강하는 기능도 수행한다.In particular, the lower plate (150) also performs the function of reinforcing the supporting force that supports the polycoat (140).
그리고, 나머지 구성은 앞서 설명한 제1실시예와 동일하다.And, the remaining configuration is the same as the first embodiment described above.
이에 더하여, 본 발명에서는 하부판지(150)의 고정력을 높여 계면에서의 층분리를 억제할 수 있도록 양측면에 앵커링제가 스프레이 코팅됨이 바람직하다.In addition, in the present invention, it is preferable that an anchoring agent is spray-coated on both sides to increase the fixing strength of the lower board (150) and prevent layer separation at the interface.
이때, 앵커링제는 폴리에틸렌수지 100중량부에 대해, 메타크레졸(M-Cresol) 10중량부, 디히드록시부탄디산 5.5중량부, 6-브로모헥산산(6-bromohexanoic acid) 10중량부 및 디클로로아세트산(Dichloroacetic Acid) 8.0중량부를 혼합하여 조성된다.At this time, the anchoring agent is prepared by mixing 10 parts by weight of m-Cresol, 5.5 parts by weight of dihydroxybutanedioic acid, 10 parts by weight of 6-bromohexanoic acid, and 8.0 parts by weight of dichloroacetic acid for 100 parts by weight of polyethylene resin.
여기에서, 메타크레졸(M-Cresol)은 앵커링 기능을 급격히 증대시켜 부착력, 고정력을 강화시킨다.Here, metacresol (M-Cresol) dramatically increases the anchoring function, strengthening the adhesion and fixing power.
또한, 디히드록시부탄디산은 혼합시 입자간 흡착에 의한 공극 감소를 막아 앵커링 특성을 강화시키고, 내열성과 방수성도 강화시킨다.In addition, dihydroxybutanedioic acid enhances anchoring properties by preventing the reduction of pores due to inter-particle adsorption when mixed, and also enhances heat resistance and waterproofing.
아울러, 6-브로모헥산산(6-bromohexanoic acid)은 산소의 흡습 침투를 막아 열화를 방지하고 내열성을 동시에 강화시킨다.In addition, 6-bromohexanoic acid blocks oxygen absorption and penetration, preventing deterioration and enhancing heat resistance at the same time.
그리고, 디클로로아세트산(Dichloroacetic Acid)은 앵커링 기능을 급격히 증대시켜 층분리를 억제하고, 계면 탈락을 차단한다.In addition, dichloroacetic acid dramatically increases the anchoring function, inhibits layer separation, and blocks interface detachment.
이에 더하여, 상기 앵커링제는 폴리에틸렌수지 100중량부에 대해, 디갈로일트리올리에이트(Digalloyl Trioleate) 10중량부, 콘드로이틴황화염(Chondroitin sulfate) 10중량부를 더 첨가할 수 있다.In addition, the anchoring agent may further include 10 parts by weight of digalloyl trioleate and 10 parts by weight of chondroitin sulfate per 100 parts by weight of polyethylene resin.
이 경우, 디갈로일트리올리에이트(Digalloyl Trioleate)는 C68H106O12를 말하며, 계면의 표면 산화를 방지하며 자외선을 차단하여 내산성, 내구성을 강화시킨다.In this case, digalloyl trioleate refers to C 68 H 106 O 12 , which prevents surface oxidation of the interface and blocks ultraviolet rays, thereby enhancing acid resistance and durability.
또한, 콘드로이틴황화염(Chondroitin sulfate)은 건조화를 방지하여 점착성이 장기간 동안 안정적으로 유지시킨다.Additionally, chondroitin sulfate prevents drying and keeps adhesiveness stable for a long time.
다른 한편, 본 발명에서는 합지시 접착력을 높이면서 계면 분리를 억제할 수 있도록 각 층간 합지력을 제공하는 접착제를 다음과 같이 구성할 수 있다.On the other hand, in the present invention, an adhesive that provides bonding strength between each layer while increasing adhesive strength during bonding and suppressing interface separation can be configured as follows.
이러한 접착제는, 폴리비닐아세테이트 100중량부에 대해, 폴리메틸펜텐(Polymethylpentene) 3.5중량부, 2,2-디알릴펜트-4-엔-1-아민(2,2-diallylpent-4-en-1-amine) 5.5중량부, 디부틸아디페이트(Dibutyl Adipate) 4.5중량부, 폴리에테르아민(PEA) 5중량부, 이소프탈산(isophthalic acid) 4.5중량부 및 2-메틸프로프-2-에노익애씨드(2-methylprop-2-enoic acid) 8.5중량부를 혼합하여 조성된다.These adhesives are composed by mixing 3.5 parts by weight of polymethylpentene, 5.5 parts by weight of 2,2-diallylpent-4-en-1-amine, 4.5 parts by weight of dibutyl adipate, 5 parts by weight of polyetheramine (PEA), 4.5 parts by weight of isophthalic acid, and 8.5 parts by weight of 2-methylprop-2-enoic acid per 100 parts by weight of polyvinyl acetate.
이때, 폴리메틸펜텐(Polymethylpentene)은 점도가 낮고 유동성이 좋아 도포하기 용이하며 특히 융점이 235℃로서 매우 높고 고온에서의 기계적 강도 우수하고 내열안정성과 견고한 앵커링력을 제공하여 계면분리를 억제하는데 기여한다.At this time, polymethylpentene has low viscosity and good fluidity, making it easy to apply, and in particular, it has a very high melting point of 235℃, excellent mechanical strength at high temperatures, heat stability, and strong anchoring power, contributing to suppressing interfacial separation.
또한, 2,2-디알릴펜트-4-엔-1-아민(2,2-diallylpent-4-en-1-amine) CAS No. 928836-00-4에 해당하는 물질로서, 수밀성, 내구성, 밀봉성을 증대시켜 층간 밀착성을 강화시키고, 방수 기능을 증대시키는데 기여한다.In addition, as a substance corresponding to 2,2-diallylpent-4-en-1-amine (CAS No. 928836-00-4), it enhances watertightness, durability, and sealing properties, strengthens interlayer adhesion, and contributes to enhancing waterproof function.
그리고, 디부틸아디페이트(Dibutyl Adipate)는 CAS No. 105-99-7에 해당하는 물질로서, 표면피막을 형성하여 자외선 차단 및 산화 방지에 따른 내변색, 내경화, 접착력과 부착력 강화에 기여한다.In addition, dibutyl adipate is a substance corresponding to CAS No. 105-99-7, which forms a surface film and contributes to anti-discoloration, anti-hardening, and strengthening of adhesiveness and bonding strength by blocking ultraviolet rays and preventing oxidation.
뿐만 아니라, 폴리에테르아민(PEA)는 CAS No. 9046-10-0에 해당하는 물질로서, 성분간 바인딩력을 강화시켜 접착력과, 층분리 억제 기능을 강화시키는데 기여한다.In addition, polyetheramine (PEA) is a substance corresponding to CAS No. 9046-10-0, which strengthens the binding force between components, contributing to enhancing adhesiveness and layer separation inhibition function.
아울러, 이소프탈산(isophthalic acid)은 폴리머 입자표면에서 입자간 분산안정성과 저장안정성을 개선하여 입자표면의 다가 양이온성을 중화함으로써 혼화성을 증대시켜 부착력을 강화시키는데 기여한다.In addition, isophthalic acid contributes to enhancing adhesion by improving inter-particle dispersion stability and storage stability on the surface of polymer particles and increasing miscibility by neutralizing the polycationic properties of the particle surface.
또한, 2-메틸프로프-2-에노익애씨드(2-methylprop-2-enoic acid)는 CAS No. 25212-88-8에 해당하는 물질로서, 에멀젼 형태이고, 내산화성에 따른 열화억제, 내염성, 탄성회복성, 유연성, 방수성을 증가시키는데 기여한다.In addition, 2-methylprop-2-enoic acid is a substance corresponding to CAS No. 25212-88-8, is in the form of an emulsion, and contributes to increasing deterioration inhibition, salt resistance, elastic recovery, flexibility, and waterproofness according to oxidation resistance.
이와 같이, 본 발명은 종이를 사용하여 지환통을 제조함으로써 재생 및 파기가 용이하되 강도는 우수하고 친환경적이면서 특히, 습기차단력이 뛰어나 탄약을 보다 안전하게 보관 유지할 수 있게 된다.In this way, the present invention manufactures a cartridge using paper, so that it is easy to recycle and destroy, yet has excellent strength and is environmentally friendly, and in particular, has excellent moisture-blocking properties, so that ammunition can be stored more safely.
