摘　　要： 研究云母粉在全钢载重子午线轮胎胎侧胶中的应用。结果表明:在胎侧胶中添加云母粉或偶联剂Si69改性云母粉,胶料的300%定伸应力、拉伸强度和导热性能提高,改性云母粉的补强效果优于云母粉;在胎侧胶中的改性云母粉用量应小于10份,否则对胶料的耐屈挠性能产生不利影响;添加云母粉可以降低轮胎生产成本,轮胎使用性能良好。 The application of mica powder in the sidewall compound of TBR tire was studied. The results showed that with the addition of mica powder or coupling agent Si69 modified mica powder, the tensile modulus at 300% elongation, tensile strength and thermal conductivity of the compound were improved. The reinforcement effect of modified mica powder was better than that of unmodified mica powder. The addition level of modified mica powder should be less than 10 phr, otherwise the flex resistance of the compound decreased. With addition of mica powder the tire production cost was reduced and tire performance was good.
