Description
본 발명은 이형효과를 개선시킨 블래더 고무조성물에 관한 것이다.The present invention relates to a bladder rubber composition with improved release effect.
타이어 제조공정중 블래더는 열수(Hot water), 증기(steam) 또는 질소가스 (N2Gas) 등의 열원과 타이어의 인너부 사이에서 열의 전달 및 타이어 내부를 일정한 형태로 유지시켜 주는 역할을 한다. 이에 따라 블래더는 공기투과도가 낮아야 하고 고온에서 열안정성, 노화물성 및 텐션 셋(Tention set) 등의 물성이 좋아야 한다. 가류공정에서 블래더의 수명 단축의 원인은 여러 가지가 있으나 주된 요인은 타이어 인너부위와 블래더 간의 붙음에 의한 겹침 및 크랙이 있다. 따라서 블래더의 수명 단축 원인을 제거하고 보다 장시간 블래더의 사용을 위해서 실제공정에서는 타이어 인너부위에 실리콘 이형제를 도포함으로써 블래더와 타이어 인너부위와의 붙음을 방지하고 있다. 이때 사용되는 대부분의 실리콘 이형제는 환경오염을 유발할 수 있는 성분을 포함하고 있기 때문에 환경 친화적이지 못하며, 이형제의 불균일한 농도 및 도포로 인하여 블래더와 타이어 인너부위의 붙음 현상을 유발할 수가 있고, 이형제를 타이어 인너부위에 도포시킨 후 건조시켜야 하므로 공정상 많은 시간이 소요되는 문제가 있다.During the tire manufacturing process, bladder plays a role of transferring heat between the heat source such as hot water, steam or N 2 gas and the inner part of the tire and maintaining the inside of the tire in a constant shape. . Accordingly, the bladder should have low air permeability and good physical properties such as thermal stability, sinterability and tension set at high temperatures. There are many causes of shortening the life of bladder in the vulcanization process, but the main factor is the overlap and cracks caused by sticking between tire inner part and bladder. Therefore, in order to eliminate the cause of shortening the life of the bladder and to use the bladder for a longer time, in the actual process, the silicone release agent is applied to the tire inner part to prevent the bladder from sticking to the tire inner part. At this time, most of the silicone releasing agents are not environmentally friendly because they contain ingredients that can cause environmental pollution, and due to the uneven concentration and application of the releasing agent, it may cause sticking of the bladder and tire inner parts. There is a problem in that it takes a lot of time in the process because it must be applied to the tire inner part and dried.
본 발명은 상기에서 언급한 문제점을 해결하기 위해 가류 블래더 조성물 내에 이형효과를 가질 수 있는 아미드 및 아민계 공정조제를 일정량 함유토록 함으로써 블래더 내에 이형효과를 가지게 하여 가류 공정상에서 타이어의 인너부위에 이형제를 도포하지 않더라도 블래더와 타이어 인너부위와의 윤활효과를 증진시켜 붙음 현상의 억제를 목적으로 한다.The present invention has a release effect in the bladder by containing a certain amount of the amide and amine processing aid that may have a release effect in the vulcanizing bladder composition to solve the above-mentioned problems to have a release effect in the bladder process to the inner portion of the tire Even if the release agent is not applied, the lubrication effect between the bladder and the inner portion of the tire is enhanced to suppress the sticking phenomenon.
본 발명의 이형효과를 개선시킨 블래더 고무는 원료고무로서 부틸고무 100 중량부에 대하여 카본블랙 N330 50 중량부, 산화아연 5 중량부, 스테아린산 2.5 중량부, 공정유로 파라핀오일(Paraffine Oil) P#2(미창석유, 한국) 5.5∼7.5 중량부, 수지 가류제로서 파라-알킬페놀(p-alkylphenol)과 포롬알데히드(formaldehyde)를 축합 반응시킨 알킬페놀 가류수지(Alkylphenol curing resin, 상품명: SP-1045, Schenectar사, USA) 10 중량부, 이형효과를 증대시키기 위해 이형제로 시판되는 아미드 및 아민족 화합물로 구성된 PA-2(Chemlease사) 0.2∼2.0 중량부를 190-195℃, 20-40분 동안 밴부리믹서(banbury mixer)를 이용하여 제조한다.Bladder rubber with improved release effect of the present invention is a raw material rubber based on 100 parts by weight of butyl rubber 50 parts by weight of carbon black N330, 5 parts by weight of zinc oxide, 2.5 parts by weight of stearic acid, paraffin oil (Paraffine Oil) P # 2 (Michang petroleum, Korea) 5.5 to 7.5 parts by weight, a condensation reaction of para-alkylphenol (p-alkylphenol) and formaldehyde (formaldehyde) as a resin vulcanizing agent (Alkylphenol curing resin, trade name: SP-1045 , Schenectar, USA) 10 parts by weight, 0.2-2 parts by weight of PA-2 (Chemlease) composed of amides and amine compounds commercially available as a release agent to enhance the release effect for 190-195 ℃, 20-40 minutes Prepared using a banbury mixer.

< 시험예 2 ><Test Example 2>
상기 표 1의 실시예 1-4 및 비교예의 조성물을 이용하여 제조한 블래더 고무를 실제 공정에서 적용평가한 결과 실시예 2-4 조성물을 이용한 블래더 고무가 타이어 가류공정에서 그린케이스에 도포되는 인사이드 스프레이를 삭제할 수 있었으며 인너고무와 블래더 고무간의 뜯김 발생 없이 양호한 수명을 나타내었다. 스프레이 삭제를 통해 뜯김 발생 유무를 육안으로 확인하였으며 뜯김 발생한 부위의 개수가 0개이면 발생안함, 5개 이내이면 약간발생, 5개 이상이면 발생으로 판정하였으며 코드노출은 자체공장 검사기준에 의거하여 측정하였고, 사용수명은 타이어 1 사이클(cycle) 가류시 1회 사용을 나타낸다. 이때 PA-2 최적사용량은 원료고무 100 중량부에 대하여 0.5-2.0 중량부를 사용한 경우 가장 좋은 이형효과를 발휘함을 알 수 있었으며 이들의 결과 측정치를 아래의 표 3에 정리하여 나타내었다.As a result of applying and evaluating the bladder rubber prepared using the composition of Example 1-4 and Comparative Example of Table 1 in the actual process, the bladder rubber using the composition of Example 2-4 was applied to the green case in the tire vulcanization process. Inside spray could be eliminated and had a good life without tearing between inner rubber and bladder rubber. It was visually checked for the occurrence of tearing through the spray removal, and if the number of tearing occurred was 0, it did not occur, if it was within 5, it occurred slightly, and if it was 5 or more, it was judged as occurring. The service life represents one use for one cycle of tire tire curing. At this time, the optimum amount of PA-2 was found to have the best release effect when 0.5-2.0 parts by weight of the raw material rubber was used. The results of these measurements are summarized in Table 3 below.

상기 표 3에서 보는 것처럼 본 발명에 의한 블래더 고무는 타이어 인너부위에 이형제를 도포하지 않아도 블래더 고무와 타이어 인너부위와의 붙음 현상을 방지할 수 있어 블래더 고무의 사용수명을 향상시킬 수 있을 뿐만 아니라 이형제를 도포하는 공정을 생략할 수 있어 타이어 생산성 향상에도 기여할 수 있다.As shown in Table 3, the bladder rubber according to the present invention can prevent the sticking phenomenon between the bladder rubber and the tire inner part without applying a release agent on the tire inner part, thereby improving the service life of the bladder rubber. In addition, the process of applying the release agent can be omitted, thereby contributing to the improvement of tire productivity.
