产品耐磨性与胎面胶混炼工艺密切相关,尤其是白炭黑的分散性及胶料门尼值高低,由于白炭黑的分散性涉及到白炭黑与硅烷偶联剂反应的适宜温度,另外门尼值的高低可通过控制生产段数来有效控制。本文围绕这一主题,对胎面胶的混炼工艺进行了优化设计与研究。一、基本要素1.主要原材料天然橡胶(NR),SMR20,马来西亚产品;炭黑N234,江西黑猫炭黑股份有限公司产品;高分散白炭黑VN3GR,赢创德固赛有限公司产品;硅烷偶联剂
The wear resistance of the product is closely related to the mixing process of the tread rubber, especially the dispersibility of silica and the Mooney value of the rubber compound. Since the dispersion of silica involves the reaction of silica and the silane coupling agent Temperature, the other Mooney value level can be effectively controlled by controlling the production segment. Based on this theme, this paper optimizes the design and study of the compounding process of tread rubber. First, the basic elements 1. The main raw materials of natural rubber (NR), SMR20, Malaysia products; carbon black N234, Jiangxi Black Cat Co., Ltd. products; highly dispersed silica VN3GR, Evonik Degussa Co., Ltd. products; silane Coupling agent
