Abstract
본 발명은 타이어의 고무조성물에 관한 것으로, 타이어의 각 부분을 압출 성형시킨 후, 각 부분을 접착하여 그린타이어를 제조하게 되는데, 그린타이어를 성형시킨 후 이를 즉시 타이어로 성형시키기는 곤란하므로, 이러한 그린타이어는 결국 타이어로의 성형작업에 이르기까지 시간이 경과할 수록 수축되기 마련인데다가, 각 부분의 수축률이 서로 다르므로, 각 부분의 칫수가 달라질 수가 있게 되어, 타이어가 설계한 대로의 형태를 유지하기 어렵게 된다. 그리하여 본 발명은 고무내에 용융점이 낮은 결정성고분자물질을 첨가하여 고무의 가공중에는 고무가 용융점이상의 온도에 놓이게 되므로 고분자물질이 녹아 충분한 유동성을 가지게하여 가공성에 영향을 받지 아니하게 하고 가공 후 온도가 낮아지면 고무내의 결정성 고분자물질이 결정을 형성시켜 시간이 경과하더라도 각 부분을 구성하는 고무가 수축되지 아니하도록 하여 타이어 각부의 칫수에 안정성을 부여하게 된 것임.The present invention relates to a rubber composition of a tire, and each part of the tire is extruded, and then each part is bonded to produce a green tire. Green tires will shrink as time passes until the tires are formed. In addition, the shrinkage of each part will be different, so that the dimensions of each part will be different. It becomes difficult to maintain. Thus, the present invention adds a crystalline polymer material having a low melting point in the rubber so that the rubber is placed at a temperature above the melting point during the processing of the rubber so that the polymer material melts to have sufficient fluidity so that the workability is not affected and the temperature after processing is low. The crystalline polymer in the ground rubber forms crystals so that the rubber constituting each part does not shrink even if time passes, thereby providing stability to the dimensions of each tire part.
