摘　　要：研究高分散性芳纶短纤维TWAROND3500在矿山轮胎胎侧胶中的应用。结果表明：在矿山轮胎胎侧胶中添加高分散性芳纶短纤维TWAROND3500可以明显降低胶料生热并提高耐磨性能，有利于延长轮胎使用寿命；高分散性芳纶短纤维TWAROND3500胎侧胶挤出和成型工艺性能好；高分散性芳纶短纤维TWAROND3500在胎侧胶中的适合用量为2～3份。In this study, aramid fiber TWARON D3500 with enhanced dispersion characteristics was applied in the sidewall compound of mining tire. The experimental results showed that the heat build-up of the vulcanizates was reduced and the abrasion resistance increased, indicating improved tire service life. TWARON D3500 offered enhanced dispersion characteristics, so that the processing properties of the sidewall compound were good during extrusion and molding processes. The optimum addition level of TWARON D3500 was 2-3 phr.
