Description

용접용 실리콘 점착 테이프{SILICON ADHESIVE TAPE FOR WELDING}Silicone Adhesive Tape for Welding {SILICON ADHESIVE TAPE FOR WELDING}

본 발명은 용접 지지구에 용접 대상 모재를 고정시키고, 용접 후 점착제의 잔재 제거를 용이하게 하기 위해 실리콘 점착제를 이용하여 용접 지지구의 저면에 부착되는 점착 테이프를 제공할 수 있는 용접용 실리콘 점착 테이프에 관한 것이다.
The present invention is to a welding silicone adhesive tape which can provide a pressure-sensitive adhesive tape attached to the bottom surface of the welding support by using a silicone adhesive to fix the base material to be welded to the welding support, and to easily remove the residue of the adhesive after welding. It is about.

잘 알려진 바와 같이, 점착 테이프는 산업용, 의료용, 가정용 등으로 많이 사용되고 있는데, 종이, 포목, 플라스틱 필름 등의 지지체의 한쪽면 또는 양쪽면에 점착제를 도포한 테이프 형태이며, 용제, 열 등을 사용하지 않고 상온에서 약간의 압력을 가해준 것만으로 점착할 수 있고, 응집력과 탄성을 가지고 있어 강하게 점착하는 반면 경질의 평활면에서는 떼어낼 수도 있는 테이프를 의미한다.As is well known, adhesive tapes are widely used for industrial, medical, and home use, and are in the form of a tape coated with adhesive on one or both sides of a support such as paper, fabric, plastic film, etc., and do not use solvent, heat, or the like. It means that the tape can be adhered only by applying a little pressure at room temperature, and has a cohesive force and elasticity, so that the adhesive can be strongly adhered, while the hard smooth surface can be peeled off.

여기에서, 점착 테이프에 사용되는 점착제는 초기 접착력, 점착력 및 응집력이 우수하고, 이들 사이의 균형이 좋아야 하며, 장기간 부착 후에 제거를 위해 박리할 경우 피착체의 표면 손상 및 오염을 유발하지 않아야 한다.Here, the adhesive used in the adhesive tape has excellent initial adhesive force, adhesive force and cohesive force, a good balance between them, and should not cause surface damage and contamination of the adherend when peeled off for removal after prolonged adhesion.

이러한 점착제 및 이를 사용한 점착 테이프는 압력에 의해 부착되기 때문에 감압성 점착 테이프(pressure-sensitive adhesive tape, PSA 테이프)로도 지칭된다.Such adhesives and adhesive tapes using the same are also referred to as pressure-sensitive adhesive tapes (PSA tapes) because they are attached by pressure.

예를 들면, 감압성 점착제(pressure-sensitive adhesives, PSA)는 점착성 수지, 점착 부여제, 가소제 및 경우에 따라 점착조제(가교제, 안정제, 노화방지재 등) 등으로 구성되며, 점착성 수지는 그 용도에 따라 열가소성 고무, 부틸 고무, 아크릴 수지, 우레탄 고무, 실리콘 수지 등이 이용될 수 있다.For example, pressure-sensitive adhesives (PSAs) are composed of adhesive resins, tackifiers, plasticizers and optionally adhesive aids (crosslinkers, stabilizers, anti-aging agents, etc.), and the adhesive resins are used for the purpose. Depending on the thermoplastic rubber, butyl rubber, acrylic resin, urethane rubber, silicone resin and the like can be used.

이러한 점착제는 점착 테이프뿐만 아니라 신발, 피혁, 세라믹, 유리, 건축, 전자, 벽지, 가구, 목재, 포장, 종이, 플라스틱 등의 접착에 매우 다양하게 사용되고 있다.Such a pressure-sensitive adhesive is used in a variety of adhesives, such as shoes, leather, ceramics, glass, architecture, electronics, wallpaper, furniture, wood, packaging, paper, plastic as well as adhesive tape.

한편, 용접 지지구에 용접 대상 모재를 고정시키기 위해 점착 테이프를 사용하고 있는데, 용접 지지구 상에 용접 대상 모재를 정위치에 위치시키고, 용접 지지구의 저면과 용접 지지구의 외측으로 노출되는 용접 대상 모재의 저면에 점착 테이프를 부착함으로써, 용접 과정에서 용접 지지구와 용접 대상 모재를 고정시킬 수 있다.On the other hand, the adhesive tape is used to fix the base material to be welded to the welding support. The base material to be welded is positioned on the welding support, and the base to be welded is exposed to the bottom of the welding support and to the outside of the welding support. By attaching the adhesive tape to the bottom surface of the, the welding support and the welding target base material can be fixed in the welding process.

상술한 바와 같은 용접 지지구에 부착되는 점착 테이프에 이용되는 점착제는 아크릴 점착제가 주로 사용되고 있는데, 용접 시 발생하는 열에 민감하여 점착력 및 응집력이 상대적으로 감소하고, 이에 따라 철판에 점착제의 잔재가 발생하기 때문에 사상(clean) 공정 시 많은 인력과 시간이 소요되는 문제점이 있다.As the adhesive used for the adhesive tape attached to the welding support as described above, an acrylic adhesive is mainly used. The adhesive and cohesive force are relatively reduced due to heat generated during welding, and thus, residue of the adhesive on the steel sheet is generated. Therefore, there is a problem that requires a lot of manpower and time during the clean process.

이에 따라, 열에 대해 강하고, 초기 접착력, 점착력 및 응집력이 우수한 점착제 및 점착 테이프의 개발이 시급한 실정이다.
Accordingly, there is an urgent need to develop an adhesive and an adhesive tape that are strong against heat and excellent in initial adhesive force, adhesive force, and cohesive force.

본 발명은 실리콘 검, 실리콘 수지 및 유기 용제를 이용하여 제조되는 실리콘 점착제를 알루미늄 호일에 코팅한 후, 이형지와 합지하여 실리콘 점착 테이프를 제공함으로써, 열에 대해 강하고, 초기 접착력, 점착력 및 응집력이 우수하고, 점착제의 잔재를 쉽게 제거할 수 있는 용접용 실리콘 점착 테이프를 제공하고자 한다.The present invention is coated with a silicone gum, a silicone resin, and an organic solvent, and then coated with an aluminum foil, and then laminated with a release paper to provide a silicone adhesive tape, which is strong against heat, excellent in initial adhesion, adhesion and cohesion, To provide a silicone adhesive tape for welding that can easily remove the residue of the adhesive.

이러서, 실리콘 점착제층(10)이 형성된 알루미늄 호일(20)을 드라이존에 투입하여 용제를 휘발시킨 후, 이형지(30)와 합지하여 실리콘 점착 테이프를 제조한다(단계208). 여기에서, 이형지(30)는 종이, 합성수지를 이용하여 제조되는 필름 등을 사용할 수 있다.Thus, the aluminum foil 20 having the silicon adhesive layer 10 is placed in a dry zone to volatilize the solvent, and then laminated with the release paper 30 to produce a silicone adhesive tape (step 208). Here, the release paper 30 may use a film or the like produced using paper, synthetic resin.

따라서, 실리콘 검, 실리콘 수지 및 유기 용제를 이용하여 제조되는 실리콘 점착제를 알루미늄 호일에 코팅한 후, 이형지와 합지하여 용접용 실리콘 점착 테이프를 제공함으로써, 열에 대해 강하고, 초기 접착력, 점착력 및 응집력이 우수한 용접용 실리콘 점착 테이프를 제공할 수 있다.
Therefore, by coating a silicone adhesive prepared using a silicone gum, a silicone resin and an organic solvent on an aluminum foil, and then laminating with a release paper to provide a silicone adhesive tape for welding, it is strong against heat, excellent in initial adhesion, adhesion and cohesion The silicone adhesive tape for welding can be provided.

이상의 설명에서는 본 발명의 다양한 실시예들을 제시하여 설명하였으나 본 발명이 반드시 이에 한정되는 것은 아니며, 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자라면 본 발명의 기술적 사상을 벗어나지 않는 범위 내에서 여러 가지 치환, 변형 및 변경이 가능함을 쉽게 알 수 있을 것이다.
While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be readily apparent that such substitutions, modifications, and alterations are possible.
