A rubber composition comprising a natural and/or synthetic rubber, a filler and an acrylamide compound represented by the formula of
X-NHCH=CH₂
wherein X is an aliphatic or alicyclic group, phenyl or phenoxyphenyl, in which said aliphatic or alicyclic group may contain halogen or oxygen in the group, said phenyl may be substituted once or twice by halogen, hydroxy, alkyl of 1 to 8 carbon atoms, alkoxy of 1 to 8 carbon atoms, nitro, cyano, carboxy or alkoxycarbonyl, and said phenoxyphenyl is represented by the formula of
wherein Q¹ and Q² independently of one another are each hydrogen, alkyl of 1 to 8 carbon atoms, cyclohexyl, phenyl, halogen, hydroxy or amino. This rubber composition is increased in its loss factor, and is useful for tires and tread parts. The resulting tires prepared from the rubber composition are improved in their gripping performance.
一种橡胶组合物,由天然和/或合成橡胶、填料和丙烯酰胺化合物组成,丙烯酰胺化合物的分子式为
X-NHCH=CH₂
其中 X 为脂肪族或脂环族基团、苯基或苯氧基苯基,其中所述脂肪族或脂环族基团中可含有卤素或氧,所述苯基可被卤素、羟基、1 至 8 个碳原子的烷基、1 至 8 个碳原子的烷氧基、硝基、氰基、羧基或烷氧基羰基取代一次或两次,所述苯氧基苯基由以下式子表示
其中 Q¹ 和 Q² 各自独立地为氢、1 至 8 个碳原子的烷基、环己基、苯基、卤素、羟基或氨基。这种橡胶组合物的损耗因子增加,适用于轮胎和胎面部件。用该橡胶组合物制备的轮胎抓地性能得到改善。
