白炭黑分散剂DST-100在全钢载重子午线轮胎胎面胶中的应用

Application of Silica Dispersing Aid DST-100 in Tread Compound of All-steel Truck and Bus Radial Tire

研究白炭黑分散剂DST-100在全钢载重子午线轮胎胎面胶中的应用。结果表明,在只用15份白炭黑的生产配方基础上,增大白炭黑用量3~8份并添加2份白炭黑分散剂DST-100,胶料的硫化特性、炭黑分散性、强伸性能和耐压缩疲劳性能与生产配方胶料相近,抗切割性能和耐磨性能提高。通过添加白炭黑分散剂DST-100,在全钢载重子午线轮胎胎面胶中适量增大白炭黑用量是可行的。

The application of silica dispersing aid DST-100 in the tread compound of all-steel truck and bus radial（TBR） tire was studied. The results showed that based on the production formula using only 15 parts of silica,when the amount of silica increased by 3～8 phr and 2 phr of silica dispersing aid DST-100 was added,the vulcanization characteristics,the dispersion of carbon black,tensile properties and compression fatigue resistance of the compound were similar to those of the compound with the original production formula,and the anti-cutting performance and wear resistance were improved. With silica dispersing aid DST-100,it was feasible to increase the amount of silica in the tread compound of all-steel truck and bus radial tire.
