The invention provides a tread base rubber with good heat resistance and wear resistance as well as a preparation method and application thereof, and belongs to the technical field of high polymer materials. The tread base rubber provided by the invention is prepared by taking N234 carbon black wet rubber as a main material and taking a super vulcanizing agent, nano zinc oxide, tear-resistant resin, an anti-aging agent, insoluble sulfur, an anti-reversion agent SL-9088 and a silane coupling agent as main auxiliary materials according to a certain proportion. The tread base rubber provided by the invention has the characteristics of low dynamic heat generation, good heat resistance, high tensile strength, high tear strength, high elongation at break, good wear resistance, high resilience value and high bonding strength with a cord fabric. The tread base rubber provided by the invention is used for stealth aircraft tires and is used under the conditions of high load and supersonic speed, under the conditions of maximum stress, high temperature and difficult heat dissipation of the part, the problem of aircraft tire damage caused by fusion, disengagement and tread throwing is not easy to occur, and the aircraft tires are good in reliability and long in service life.
本发明提供了一种耐热性好且耐磨的胎面基部胶及其制备方法和应用,属于高分子材料技术领域。本发明提供的胎面基部胶以N234炭黑湿法胶为主材料,以超级硫化剂、纳米氧化锌、抗撕裂树脂、防老剂、不溶性硫磺、抗硫化返原剂SL‑9088、硅烷偶联剂为主要辅助材料,按一定的比例制备而成。本发明提供的胎面基部胶具有动态生热低、耐热性能好、拉伸强度、撕裂强度和扯断伸长率高,同时具有耐磨性能好、回弹值较高、与帘布层粘合强度高的性能特点。本发明提供的胎面基部胶用于隐形飞机轮胎,在高载、超音速条件下使用,在该部位应力最大、温度高、散热困难的状况下,不易出现熔融、脱开、甩胎面而使飞机轮胎损坏的问题,飞机轮胎的可靠性好、寿命长。
