轮胎胎面,特别是航空轮胎或重型车辆轮胎胎面是由以交联型胶料为基料制成的。这种交联型胶料具有如下成分:100重量份橡胶(在100重量份橡胶中有40～100重量份聚异戊二烯橡胶、0～60重量份高不饱和二烯系橡胶)、1～25重量份具有50～120℃玻璃化温度的聚萜烯树脂、0.1～10重量份聚硫代硫酸盐防硫化返原剂(其化学式为:MO3S-S-X-S-SO3M,式中:X为1个亚烃基团或1个具有2个或2个以上亚烃基单元的基团;几对亚烃基单元与1个氧原子或1个硫原子、SO2-、-NH-、-NH2+-、-NlC1-16烷基、-COO-链接,或者与亚芳基或环烷基团链接;M为金属)。
Tire treads, particularly aerospace tires or heavy-duty vehicle tire treads, are made from cross-linked size based materials. The crosslinked compound has the following composition: 100 parts by weight of rubber (40 to 100 parts by weight of polyisoprene rubber and 0 to 60 parts by weight of highly unsaturated diene rubber in 100 parts by weight of rubber), 1 ~ 25 parts by weight of a polyterpene resin having a glass transition temperature of 50 to 120 ° C and 0.1 to 10 parts by weight of a polythiosulfate anti-reversion reversion agent of the formula: MO3S-SXS-SO3M wherein X is 1 A hydrocarbylene group or a group having two or more hydrocarbylene units; several pairs of hydrocarbylene units and one oxygen atom or one sulfur atom, SO2-, -NH-, -NH2 +, -NCl1 -16 alkyl, -COO- link, or linked with an arylene or cycloalkane group; M is a metal).
