Description

타이어 외부용 수성계 이형제Aqueous release agent for tire exterior

본 발명은 타이어 외부용 수성계 이형제에 관한 것으로서, 보다 상세하게는 인체에 무해한 물을 용매에 사용함으로써 환경오염의 우려와 인체에 대한 유해성이 제거됨과 아울러 타이어의 외부에 도포시 그린타이어와 몰드간의 이형성 및 윤활성을 부여하게 되는 수성계 이형제에 관한 것이다.The present invention relates to a water-based mold release agent for the exterior of the tire, and more particularly, by using water that is harmless to the human body in a solvent, concerns about environmental pollution and harmful effects to the human body are eliminated, and when applied to the outside of the tire between the green tire and the mold. It relates to an aqueous release agent that imparts mold release and lubricity.

최근들어 타이어를 제조하는 공정중에 환경오염 및 인체 유해성 물질 제거를 통하여 환경 친화적인 물질개발 및 도입에 초점을 두고 있는 실정이다. 특히, 제품을 제조하는 공정중에 발생되는 유해물질을 제거하고 화재의 위험으로부터 보호함과 아울러 대기 및 수질오염을 방지하기 위한 노력을 기울이고 있다.Recently, the situation is focused on the development and introduction of environmentally friendly materials through the removal of environmental pollution and human harmful substances during the tire manufacturing process. In particular, efforts are being made to remove harmful substances generated during the manufacturing process of products, to protect them from the risk of fire, and to prevent air and water pollution.

종래에는 타이어용 외부이형제로서 톨루엔계 유기 혼합물인 한솔 용매에 무기필러 및 폴리머를 용해하여 제조된 용액을 그린타이어 외부에 도포시켜 가류시 몰드와의 이형성 증진과 에어브리드(air breed)를 유도하여 제반타이어 문자의 선명도를 발현시키고 몰드와의 인출시 분리가 용이하도록 사용해 왔다. 이때 유기 용매계용액을 일정한 분사 챔버(chamber)내에서 분사시키므로써 유기 용매가 공기중에 방출되어 환경을 오염시킬 뿐만 아니라 인체에 유해한 영향을 미치게 되는 문제점이 있었다. 또한 용액의 제조에 따른 취급 부주의시 화재의 위험 등이 항상 내재하고 있었다.Conventionally, as an external mold release agent for tires, a solution prepared by dissolving an inorganic filler and a polymer in a Hansol solvent, which is a toluene-based organic mixture, is applied to the outside of the green tire to enhance mold release properties and induce air breeding during vulcanization. It has been used to express the clarity of tire letters and to facilitate separation when withdrawing from a mold. At this time, by spraying the organic solvent solution in a certain spray chamber (chamber) there is a problem that the organic solvent is released into the air to pollute the environment as well as harmful to the human body. In addition, the risk of fire was always inherent in the careless handling of the solution.

이에 본 발명자는 상기한 문제점들을 해결하고자 예의 검토한 결과, 종래의 유기 용매계 스프레이 용액 대신에 환경오염의 우려와 인체 유해성이 없는 환경친화적 수성계 용액을 그린타이어 외부이형제로서 사용하므로써 타이어의 몰드이형 특성을 실현함과 함께 환경개선을 도모한다는 것을 발견하여 본 발명을 완성하게 되었다.Accordingly, the present inventors have diligently studied to solve the above problems, and as a result of using the environmentally friendly aqueous solution without the concern of environmental pollution and human health instead of the conventional organic solvent spray solution, mold release of tires is performed by using the green tire external release agent. The present invention has been completed by discovering that the characteristics are improved and the environment is improved.

즉, 본 발명은 탄화수소계 폴리머 수지 3∼5중량%, 실리케이트 유기안료 6∼10중량%, 습윤분산제인 비이온계 폴리에틸렌수지 2∼5중량%, 고비점 이소프로필 알코올 2∼3중량%, 불소계 이형제 3∼5중량% 및 용매인 물 75∼80중량%를 포함하는 것을 특징으로 하는 타이어 외부용 수성계 이형제에 관한 것이다.That is, the present invention is 3 to 5% by weight of the hydrocarbon-based polymer resin, 6 to 10% by weight of the silicate organic pigment, 2 to 5% by weight of nonionic polyethylene resin as a wet dispersant, 2-3% by weight of high boiling isopropyl alcohol, fluorine-based It relates to a tire external aqueous-based release agent comprising 3 to 5% by weight of the release agent and 75 to 80% by weight of water as a solvent.

본 발명에 따른 수성계 이형제의 사용 공정 조건은 다음과 같다. 스프레이건 에어 압력은 6∼7kgf/㎠, 노즐직경은 0.6∼0.8㎜, 탱크의 에어 압력은 2.0∼3.0kgf/㎠, 교반기 날개길이는 90㎜, 교반기 RPM은 20∼50으로 유지시키며, 이때 스프레이 탱크내 스트레이너 메쉬(Mesh)는 60으로 하고, 또한 건조장치의 열매온도는 100℃의 뜨거운 공기를 60℃로 하여 사용하고 이때 압력은 3.0kgf/㎠ 이상 유지시킨다. 아울러, 스프레이 건과 건간의 분사거리는 30∼40㎝, 분사각도는 상하 25∼35˚로 유지시키고, 분사는 1.5초 정도 실시한다.Process conditions for use of the aqueous release agent according to the present invention are as follows. Spray gun air pressure is 6 ~ 7kgf / ㎠, nozzle diameter is 0.6 ~ 0.8mm, tank air pressure is 2.0 ~ 3.0kgf / ㎠, stirrer vane length is 90mm, stirrer RPM is maintained at 20 ~ 50 The strainer mesh in the tank is 60, and the fruit temperature of the drying apparatus is 100 ° C. with hot air at 60 ° C., and the pressure is maintained at 3.0 kgf / cm 2 or more. In addition, the spraying distance between the spray gun and the gun is 30 to 40 cm, the spraying angle is maintained at 25 to 35 degrees up and down, and the spraying is performed for about 1.5 seconds.

본 발명의 수성계 이형제는 종래의 유기용매계 이형제에 비하여 화재의 위험성, 환경오염 및 인체에 대한 유해성이 없으며, 아울러, 작업공정성이 양호하고, 몰드내 적정 흐름성과 에어브리드 특성을 나타낸다. 또한 고무간 접착부위에서는 접착력을 보여주면서 고무 표면에서 필러 흑색도가 미세하고 고무내 은폐력도 향상되도록 하는 등의 제반 이형 특성을 발현하며, 특히, 가류몰드내 가류 후 몰드 오염이 최소화되게 한다.The aqueous release agent of the present invention has no risk of fire, environmental pollution and harm to human body, and has good work processability, and shows proper flowability and air bleed property in the mold compared to the conventional organic solvent release agent. In addition, the adhesion between the rubber parts exhibits various release characteristics such as filler blackness at the rubber surface and improved hiding power in the rubber surface while showing adhesion, and in particular, minimizes mold contamination after vulcanization in the vulcanization mold.
