摘要： A rubber composition for use in a tire tread and a respective tread and pneumatic tire with such a tread is dieclosed. The rubber composition comprises from 20 to 90 part by weight per 100 parts by weight of rubber (phr) of a solution polymerized styrenebutadiene rubber; from 10 to 80 phr of a polybutadiene rubber, wherein from 0 to 20 weight percent of the polybutadiene rubber is a syndiotactic polybutadiene rubber comprising at least 70 percent of monomeric units in syndiotactic 1,2 configuration and the balance of the polybutadiene rubber comprises at least 90 percent of monomeric units in cis-1,4 configuration; and from 50 to 150 phr of pre-hydrophobated silica, preferably precipitated silica, wherein the pre-hydrophobated silica is hydrophobated prior to its addition to the rubber composition by treatment with at least one silane selected from the group consisting of alkylsilanes, alkoxysilanes, organoalkoxysilyl polysulfides and organomercaptoalkoxysilanes.
摘要翻译： 将用于轮胎胎面的橡胶组合物和具有这种胎面的相应胎面和充气轮胎封闭起来。 该橡胶组合物包含每100重量份橡胶（phr）溶液聚合的苯乙烯丁二烯橡胶20至90重量份; 10至80phr的聚丁二烯橡胶，其中0至20重量％的聚丁二烯橡胶是间同立构聚丁二烯橡胶，其包含至少70％的间同立构1,2构型的单体单元，其余的聚丁二烯橡胶至少包含 90％的顺式-1,4构型的单体单元; 和50至150phr预先疏水化的二氧化硅，优选沉淀二氧化硅，其中预先疏水化的二氧化硅在其加入橡胶组合物之前通过用至少一种选自烷基硅烷，烷氧基硅烷，有机烷氧基甲硅烷基硅烷 多硫化物和有机巯基烷氧基硅烷。
