The invention provides a rubber composition which is prepared from the following components in parts by weight: 50 to 85 parts of isoprene rubber, 10 to 30 parts of butadiene rubber, 2 to 10 parts of high styrene rubber, 5 to 10 parts of trans-isooctene rubber, 3 to 10 parts of zinc oxide, 0.5 to 5 parts of stearic acid, 0.5 to 2 parts of hydroquinone anti-aging agent, 0.5 to 2 parts of ketoamine anti-aging agent, 50 to 80 parts of reinforcing agent, 0.1 to 0.5 part of scorch retarder, 1.0 to 3.0 parts of accelerant and 2 to 5 parts of vulcanizing agent. The invention provides a preparation method and application of a rubber composition. According to the rubber composition provided by the invention, the trans-isooctene rubber is used for replacing plasticizers such as aromatic hydrocarbon oil, so that the processability is improved, the content of micromolecular emigration substances is reduced, and the modulus of vulcanized rubber is improved by adding the high styrene rubber and reducing the use amount of carbon black.
本发明提供了一种橡胶组合物,以重量份数计,包括:异戊橡胶50~85份,顺丁橡胶10~30份,高苯乙烯橡胶2~10份,反式异辛烯橡胶5~10份,氧化锌3~10份,硬脂酸0.5~5份,对苯二酚类防老剂0.5~2份,酮胺类防老剂0.5~2份,补强剂50~80份,防焦剂0.1~0.5份,促进剂1.0~3.0份,硫化剂2~5份。本申请提供了一种橡胶组合物的制备方法和应用。本申请提供的橡胶组合物通过使用反式异辛烯橡胶替代芳烃油等增塑剂,提高加工性的同时减少了小分子迁出物的含量,通过加入高苯乙烯橡胶,减少炭黑用量,提高了硫化胶的模量。
