防老剂橡胶贴片、其制备方法及使用防老剂橡胶贴片制备轮胎的方法
本发明公开了一种防老剂橡胶贴片、其制备方法、及使用防老剂橡胶贴片制备轮胎的方法，本发明利用防老剂的扩散特性，设计一种防老剂浓度高且易于释放的防老剂橡胶贴片设置于轮胎的最内层，经由防老剂迁移扩散至其他部件尤其是胎侧部位，弥补随时间推移胎侧部位中防老剂的流失，可有效地长时间维持抗臭氧老化的效果，防止龟裂。解决现有技术因存在外观变色的隐患，防老剂用量受限，难以通过进一步增加胎侧部位自身的防老剂含量来增强抗臭氧性能的问题。
The invention discloses an anti-aging agent rubber patch, a preparation method of the anti-aging agent rubber patch and a method for preparing a tire by using the anti-aging agent rubber patch. The anti-aging agent rubber patch which is high in anti-aging agent concentration and easily releases an anti-aging agent is designed to be arranged on the innermost layer of the tire by utilizing the diffusion characteristic of the anti-aging agent. The anti-aging agent migrates and diffuses to other parts, especially the sidewall part, so that the loss of the anti-aging agent in the sidewall part as time goes on is compensated, the anti-ozone aging effect can be effectively maintained for a long time, and cracking is prevented. The problems that in the prior art, due to the hidden danger of appearance discoloration, the dosage of the anti-aging agent is limited, and the anti-ozone performance is difficult to enhance by further increasing the content of the anti-aging agent at the sidewall part are solved.
