The invention provides a low-heat-generation rubber composition which comprises the following components in parts by weight: 93-98 parts of isoprene rubber, 2-7 parts of trans-polyisoprene, 25-45 parts of a reinforcing agent, 2-5 parts of zinc oxide, 1-3 parts of stearic acid, 1-3 parts of an anti-aging agent, 0.5-2 parts of bonding resin, 0.5-3 parts of a curing agent, 0.5-1.5 parts of an accelerant and 1.5-3.0 parts of a vulcanizing agent. The invention further provides the aviation tire body rubber. According to the rubber composition provided by the invention, heat generation is greatly reduced by increasing the rubber content of a rubber compound, and the surface viscosity is reduced while the Green strength is improved by further adding trans-polyisoprene, so that the condition of winding and unwinding jamming of a calendered cord fabric can be solved, and the service life of the calendered cord fabric is prolonged. And meanwhile, the problem of coating adhesion damage in the cloth sleeve sleeving process in the tire blank forming process is solved.
本发明提供了一种低生热的橡胶组合物,以重量份计,包括:异戊橡胶93~98份,反式聚异戊二烯2~7份,补强剂25~45份,氧化锌2~5份,硬脂酸1~3份,防老剂1~3份,粘合树脂0.5~2份,固化剂0.5~3份,促进剂0.5~1.5份,硫化剂1.5~3.0份。本申请还提供了一种航空胎体胶。本发明提供的橡胶组合物通过提高混炼胶含胶率大幅度降低生热,进一步通过添加反式聚异戊二烯提高格林强度的同时,降低了表面粘性,能够解决压延帘布收卷放卷卡顿情况,同时解决胎坯成型过程中布筒套筒过程覆胶黏连破坏的问题。
