摘　　要：研究国产高性能天然橡胶(NR)替代泰国进口NR在航空轮胎胎面胶中的应用。结果表明:国产高性能NR的各项理化性能满足GB/T 8089—2007要求;在航空轮胎胎面胶配方中以国产高性能NR等量替代泰国进口NR,胶料的门尼粘度降低,焦烧时间缩短,硫化速度加快,拉伸强度和拉断伸长率提高,耐老化性能稍差,动态生热水平相当。The application of domestic high performance natural rubber(NR) to replace imported NR from Thailand in the tread compound of aircraft tire was studied.The results showed that,all physicochemical properties of the domestic high performance NR met the requirements of GB/T 8089—2007.When the domestic high performance NR was used to replace the imported NR from Thailand in the tread compound formula of aircraft tire by the same amount,the Mooney viscosity of the compound was reduced,the scorch time was shortened,the vulcanization speed was accelerated,the tensile strength and elongation at break were improved,the aging resistance was slightly worse,and the dynamic heat build-up level was the same.
