The present invention discloses a winter tire tread rubber composition which comprises a diene polymer, a filler, a silane coupling agent and aramid staple fibers, the glass transition temperature ofthe diene polymer is not higher than -30 DEG C, and compared with 100 parts by weight of the diene polymer, the filler comprises 10-70 parts by weight of white carbon black and 20-30 parts by weight of carbon black, the aramid staple fibers are para-aramid staple fibers Sulfon3001 of which the surfaces are modified by oxides, and the usage amount of the aramid staple fibers is 1-10 parts. According to the invention, the interaction between the tread and the ice pavement is increased through the modified aramid staple fibers sulfur300 so that the friction force is improved.
本发明公开了一种冬季轮胎的胎面橡胶组合物,包括二烯烃聚合物、填料、硅烷偶联剂及芳纶短纤维,所述二烯烃聚合物的玻璃转化温度不高于‑30℃,相比于100重量份的二烯烃聚合物,所述填料包括10‑70份的白炭黑和20‑30份的炭黑,所述芳纶短纤维采用表面经过氧化物改性的对位芳纶短纤维Sulfron3001、且使用量为1‑10份。本发明通过改性芳纶短纤维sulfron300增加胎面与冰路面之间的相互作用,以此提高摩擦力。
