随着汽车工业和高速公路的发展,对轮胎性能要求越来越高,为满足市场对轮胎质量的高要求,需要不断改进胶料的性能。子午线轮胎胎圈上三角胶在轮胎运行过程中为主要承重部位,轮胎在运行时此处生热过大会造成轮胎早期的胎圈损坏,给企业的市场竞争带来不利影响。因此,需要不断改进三角胶的使用性能。一、实验1.主要原材料NR,牌号SMR20,马来西亚;炭黑N326,江西黑猫炭黑公司;白炭黑,山东联科白炭黑有限公司;
With the development of the automobile industry and the expressway, the performance requirements of the tires are getting higher and higher. In order to meet the high requirements of the market for tire quality, the performance of rubber compounds needs to be continuously improved. The apex of the radial tire bead is the main load-bearing part during tire running. When the tire runs hot during the assembly, the tire bead will be damaged in the early stage, which will adversely affect the market competition. Therefore, the need to continuously improve the use of apex performance. First, the experiment 1. The main raw material NR, grade SMR20, Malaysia; carbon black N326, Jiangxi black cat black company; white carbon black, Shandong Branch of the White Carbon Co., Ltd.;
