摘要
研究橡胶均匀分散剂FC-303在全钢载重子午线轮胎胎面胶中的应用,并与普通分散剂A50P进行对比。结果表明:在胎面胶中以分散剂FC-303替代分散剂A50P,胶料的门尼粘度明显降低,炭黑分散度提高;硫化胶的物理性能和耐热老化性能变化不大,压缩生热降低,耐磨性能提高;成品轮胎的耐久性能达到企业标准要求;分散剂FC-303的最佳用量为2份。
The application of rubber dispersing agent FC-303 in the tread compound of truck and bus radial tire was investigated and compared to common dispersing agent A50P. The Mooney viscosity of the compound with FC-303 was significantly lower than that with A50P, and the dispersion of carbon black was better. The physical properties and aging property of the vulcanizates with FC-303 was similar to that with A50P,the compression heat build-up was lower,and the wear resistance was better. The endurance performance of the finished tire by using FC-303 to replace ASOP in the tread compound met the requirements of enterprise standards. The optimal addition level of dispersing agent FC-303 was 2 phr.
