Description
본 발명은 합성섬유 원단에 폴리우레탄 수지 코팅을 통한 방탄복 내장재 커버용 코팅 원단의 제조방법에 관한 것으로서 고주파 융착시 고강도의 접착강도를 가지도록 하는 것이다. The present invention relates to a method of manufacturing a coating fabric for a body armor interior material cover through a polyurethane resin coating on a synthetic fiber fabric, and to have high strength adhesive strength during high frequency fusion.
방탄복은 탄환 및 포탄 파면으로 인한 부상을 줄이려는 목적으로 만들어진 의류로서, 일반적으로 군인, 경찰, 사설 경호원들이 주로 착용하여 교전 상황에서 실탄 및 폭발물의 파편으로부터 신체를 보호한다.Body armor is a clothing made for the purpose of reducing injuries caused by bullets and shell destruction, and is generally worn by soldiers, police officers, and private bodyguards to protect the body from fragments of live ammunition and explosives in combat situations.
이러한 방탄복은 방탄재와 그 방탄재를 둘러싸는 커버로 구성되는데, 방탄재의 수납 및 방탄복으로서의 형상제조를 위해 커버간의 접착을 하게 되는데, 종래에는 봉재공정에 의한 방법에만 의존함으로써 작업의 어려움으로 인해 생산성이 낮았으며, 봉재공정 후 수분의 침투에 의한 내구성 약화를 방지하기 위해 봉재 부위에 다시 심실링 테이프로 부착하여야 했기 때문에 작업이 어려우며 생산성이 낮은 문제가 있었다. 또한, 이 경우 심실링 테이프와 직물의 경계면에서 접착강도가 현저하게 떨어져 습윤상태에서 지속적인 내구성을 유지하기 어려운 문제점이 있었다.Such a bulletproof suit consists of a bulletproof material and a cover surrounding the bulletproof material, and adhesion between the covers is performed for storing the bulletproof material and manufacturing the shape as a bulletproof clothing. This was low, and there was a problem of low productivity and difficult work because it had to be attached to the bar again with a seam sealing tape to prevent deterioration of durability due to penetration of moisture after the barring process. In addition, in this case, the adhesive strength at the interface between the seam sealing tape and the fabric is significantly lowered, so that it is difficult to maintain continuous durability in a wet state.
그러므로 본 발명에서는 합성섬유 직물원단에 폴리우레탄 수지 코팅을 하여 고주파 융착시 접착강도가 우수한 코팅 원단을 제조함으로써 기존의 봉제 및 심실링 공정에 비해 3배 이상의 접착강도를 가져 접착강도 및 생산성이 우수한 방탄복 내장재 커버용 소재를 제공하는 것을 기술적과제로 한다. Therefore, in the present invention, the synthetic fiber fabric is coated with a polyurethane resin to produce a coated fabric having excellent adhesion strength during high frequency fusion, so that it has three times more adhesion strength than the existing sewing and seam sealing processes, so that it has excellent adhesion strength and productivity. The technical task is to provide a material for the interior material cover.
그러므로 본 발명에 의하면, 합성섬유 직물원단의 표면에 폴리우레탄수지 100~120 중량부 : 톨루엔 30~40 중량부 : 가교제 2~5중량부를 혼합한 폴리우레탄 베이스 코팅액으로 코팅한 후, 상기 폴리우레탄 베이스 코팅된 직물에 폴리우레탄 수지 100~120 중량부 : 톨루엔 25~35 중량부 : MEK 5~10중량부를 혼합한 폴리우레탄 탑 코팅액을 코팅하는 것을 특징으로 하는 접착강도가 우수한 방탄복 내장재 커버용 코팅 원단의 제조방법이 제공된다.Therefore, according to the present invention, after coating with a polyurethane base coating solution mixed with 100 to 120 parts by weight of a polyurethane resin: 30 to 40 parts by weight of toluene: 2 to 5 parts by weight of a crosslinking agent, the polyurethane base The coated fabric is coated with
이하 본 발명을 보다 상세히 설명하기로 한다.Hereinafter, the present invention will be described in more detail.
본 발명은 합성섬유 직물원단의 표면에 폴리우레탄 베이스 코팅 후, 폴리우레탄 탑 코팅하는 것을 특징으로 하는 접착강도가 우수한 방탄복 내장재 커버용 코팅 원단의 제조방법으로서 원단의 접착시 고주파 융착방법에 의해 접착함으로써 접착강도를 향상시키는 것이다.The present invention is a method of manufacturing a coating fabric for a body armor interior material cover having excellent adhesive strength, characterized by coating a polyurethane base on the surface of a synthetic fiber fabric and then coating a polyurethane top. It is to improve the adhesive strength.
본 발명에서 제조되는 방탄복 내장재 커버용 코팅 원단의 기재는 합성섬유 직물원단으로서 폴리에스테르 직물 또는 나일론 직물이 바람직하며, 특히 나일론66 립스탑 경량 70 Denier 원단을 사용하는 것이 원단과 코팅되는 폴리우레탄 수지와의 계면 접착강도를 향상시키고, 원단의 접착을 위해 고주파 융착 후 섬유와 수지간의 결합력을 극대화시켜 접착강도를 향상시킬 수 있어 바람직하다. The base material of the coated fabric for the body armor interior material cover produced in the present invention is preferably a polyester fabric or nylon fabric as a synthetic fiber fabric fabric, and in particular, it is preferable to use nylon 66 ripstop lightweight 70 Denier fabric between the fabric and the polyurethane resin coated. It is desirable to improve the interfacial adhesion strength and to maximize the bonding strength between the fiber and the resin after high-frequency fusion for the adhesion of the fabric to improve the adhesion strength.
본 발명에서는 상기 기재인 합성수지 직물원단에 폴리우레탄 베이스 수지 코팅과 폴리우레탄 탑 코팅공정을 행하여 폴리우레탄 수지와의 계면 접착강도를 향상시키고, 고주파 융착 후 섬유와 수지간의 결합력을 극대화시켜 접착강도를 향상시킨다.In the present invention, a polyurethane base resin coating and a polyurethane top coating process are performed on the synthetic resin fabric fabric as the base material to improve the interfacial adhesion strength with the polyurethane resin, and after high-frequency fusion, the bonding strength between the fiber and the resin is maximized to improve the adhesive strength. Let it.
먼저, 폴리우레탄 베이스 수지 코팅은 폴리우레탄수지 100~120 중량부 : 톨루엔 30~40 중량부 : 가교제 2~5중량부를 혼합한 폴리우레탄 베이스 코팅액으로 코팅하는데, 직물과 코팅수지를 코팅하는 나이프와의 간격을 2mm 조건으로 2회 코팅하며, 이때 사용되는 나이프 타입은 V(브이) 형상의 나이프(Knife)를 사용함으로써 직물의 기존 물성을 확보하면서 직물과 베이스 수지간의 접착강도를 증대시킨다. First, the polyurethane-based resin coating is coated with a polyurethane base coating solution mixed with 100 to 120 parts by weight of polyurethane resin: 30 to 40 parts by weight of toluene: 2 to 5 parts by weight of a crosslinking agent. Coating is carried out twice under a condition of 2mm spacing, and the knife type used at this time uses a V (V)-shaped knife to increase the adhesive strength between the fabric and the base resin while securing the existing physical properties of the fabric.
폴리우레탄수지 100중량부미만에서는 원단표면에 코팅되는 수지층의 두께가 얇아져서 많은 횟수의 베이스 코팅처리를 거치더라도 탑 코팅 공정 시 충분한 두께의 폴리우레탄 수지층(70㎛ 이상)을 확보할 수 없는 문제가 발생하며, 120중량부초과시에는 폴리우레탄 수지의 점도가 높아서 1회 코팅 시 다량의 코팅수지가 원단표면에 도포되어 다음 코팅공정 시 기존 원단표면에 코팅층을 깍아내는 현상으로 폴리우레탄 수지층(70㎛ 이상)을 확보할 수 없는 문제가 발생할 수 있다. 가교제의 경우 폴리우레탄 수지의 중량과 연동되므로 상기의 비율로 주입 및 혼합이 필요한다. If the polyurethane resin is less than 100 parts by weight, the thickness of the resin layer coated on the fabric surface becomes thin, so it is impossible to secure a polyurethane resin layer (70㎛ or more) of sufficient thickness during the top coating process even after many times of base coating treatment. Problems occur, and if the polyurethane resin exceeds 120 parts by weight, the polyurethane resin has a high viscosity. Therefore, a large amount of coating resin is applied to the fabric surface at one time of coating, and the coating layer is cut off the existing fabric surface during the next coating process. 70㎛ or more) may not be secured. In the case of the crosslinking agent, since it is interlocked with the weight of the polyurethane resin, injection and mixing are required in the above ratio.
상기 폴리우레탄 베이스 수지 코팅처리 시 사용되는 폴리우레탄 수지는 아로마틱(Aromatic) 2 액형 폴리우레탄으로서 이소시아네이트 가교제를 사용하며, 점도 10,000 cps, 고형분 함량이 75중량%인 폴리우레탄 수지를 사용하는 것이 다음 공정인 탑 코팅공정 시 원단표면에 코팅층을 두껍게 가공이 가능하도록 한다. The polyurethane resin used in the polyurethane base resin coating treatment is an aromatic two-component polyurethane, using an isocyanate crosslinking agent, and using a polyurethane resin having a viscosity of 10,000 cps and a solid content of 75% by weight is the next step. During the top coating process, the coating layer can be thickened on the fabric surface.
이후, 상기 폴리우레탄 베이스 코팅된 직물에 폴리우레탄 탑 코팅을 하게 되는데, 폴리우레탄 수지 100~120 중량부 : 톨루엔 25~35 중량부 : MEK 5~10중량부를 혼합한 폴리우레탄 탑 코팅액을 코팅하게 된다. Thereafter, a polyurethane top coating is applied to the polyurethane-based fabric coated with a polyurethane top coating solution mixed with 100 to 120 parts by weight of polyurethane resin: 25 to 35 parts by weight of toluene: 5 to 10 parts by weight of MEK. .
코팅된 원단을 이용한 고주파 융착 접착공정은 기존의 봉재공정과 심실링 공정을 대체할 수 있는 공정이지만 지금까지는 기존 방식보다 접착강도가 낮아서 적용이 어려웠으며, 원인분석결과 두께가 얇은 원단표면에 코팅 수지를 두껍게 도포하기가 어려웠다. 이에 본 발명에서는 베이스 코팅수지와 탑 코팅수지의 배합비, 코팅장비에서 가공 시 나이프의 형상조건, 원단과 나이프의 간격 뿐만아니라 접착력이 우수한 베이스수지 코팅 후 탑 코팅을 통해 폴리우레탄 코팅층 두께를 70㎛ 이상으로 가공함으로써 우수한 접착강도를 가지게 된다. The high frequency fusion bonding process using coated fabric is a process that can replace the existing sewing process and seam sealing process, but it was difficult to apply because of the lower adhesive strength than the existing method. It was difficult to apply thickly. Accordingly, in the present invention, the thickness of the polyurethane coating layer is increased to 70㎛ or more through the top coating after coating the base resin having excellent adhesion as well as the mixing ratio of the base coating resin and the top coating resin, the shape condition of the knife when processing in the coating equipment, the distance between the fabric and the knife. It has excellent adhesive strength by processing it.
상기 폴리우레탄 탑 코팅액의 폴리우레탄 수지는 실리콘 함유율 10~15중량%, 고형분 25~30중량%인 폴리우레탄 수지인 것이 접착강도 및 가공성이 우수한데, 실리콘 함유율 10중량%미만에서는 접착강도가 낮아지는 문제가 발생하며, 15중량% 초과 시에는 과다한 무기물량으로 인해 코팅가공의 불균형 문제가 발생할 수 있다. 고형분 30중량%초과시에도 실리콘 함유율 15중량% 초과시 발생되는 문제와 동일한 문제가 발생할 수 있다.The polyurethane resin of the polyurethane top coating solution is a polyurethane resin having a silicone content of 10 to 15% by weight and a solid content of 25 to 30% by weight, which has excellent adhesive strength and processability, but when the silicone content is less than 10% by weight, the adhesive strength is lowered. A problem occurs, and when it exceeds 15% by weight, an imbalance problem in coating processing may occur due to an excessive amount of inorganic matter. Even when the solid content exceeds 30% by weight, the same problem as the problem that occurs when the silicone content exceeds 15% by weight may occur.
탑코팅은 점도 10,000cps 조건으로 J 타입 나이프(Knife)를 사용하여 행하게 되는데, 최종 코팅층의 두께는 70㎛ 이상인 것이 우수한 접착강도를 가진다. Top coating is performed using a J-type knife (Knife) with a viscosity of 10,000 cps, and the thickness of the final coating layer having a thickness of 70 μm or more has excellent adhesive strength.
이렇게 제조된 코팅원단은 고주파 융착공정을 통해 직물의 코팅면 끼리 접착시켜 방탄복 내장재 커버로 제작하여 방탄소재의 수납을 하게 된다. 상기 고주파 융착공정은 공지의 기술로서 450Hz 정도의 높은 주파수의 전류를 두 개의 코팅원단면이 맞닿게 놓은 후 압력을 가해주면 이때 발생되는 열로 접촉된 코팅원단이 접착되는 방식으로, 접착속도가 빠르며, 국부적인 가열로 원단의 변형의 위험성이 없다는 장점이 있다. 이렇게 폴리우레탄 수지 코팅 처리된 코팅직물은 직물간의 접착을 위한 고주파 융착 공정 후 접착강도가 40N 이상인 것으로 나타나, 기존의 봉제 또는 심실링 공정에 비해 3배 이상의 접착강도를 가지게 된다. The coated fabric thus produced is bonded to each other through a high-frequency fusion process to form a body armor cover to accommodate the bullet-proof material. The high frequency fusion process is a known technique, in which a high frequency current of 450 Hz is placed in contact with the two coating fabric surfaces and pressure is applied to bond the coating fabric in contact with the heat generated at this time. There is an advantage that there is no risk of deformation of the fabric by local heating. This polyurethane resin-coated coated fabric appears to have an adhesive strength of 40N or higher after a high-frequency fusion process for adhesion between fabrics, and has an adhesive strength of three times or more compared to the existing sewing or seam sealing process.
그러므로 본 발명에 의하면, 합성섬유 직물원단에 폴리우레탄 수지 코팅을 하여 고주파 융착시 접착강도가 우수한 코팅 원단을 제조함으로써 기존의 봉제 또는 심실링 공정에 비해 3배 이상의 접착강도를 가져 접착강도 및 생산성이 우수한 방탄복 내장재 커버용 소재를 제공할 수 있는 효과가 있다. Therefore, according to the present invention, by coating a synthetic fiber fabric with a polyurethane resin to produce a coated fabric having excellent adhesion strength during high frequency fusion, it has an adhesion strength of more than three times compared to the existing sewing or seam sealing process, resulting in improved adhesion strength and productivity. There is an effect that can provide a material for an excellent body armor interior material cover.
