介绍了用尼龙与BIMSM制成的动态硫化合金。它不仅具有卓越的柔性和韧性,同时还有优异的不透气性,可以用作轮胎气密层。该气密层与溴化丁基橡胶气密层相比之,能保持或改善轮胎的充气压力保持率,降低胎体内压,减少滚动阻力,削减轮胎质量,改善轮胎性能。 The dynamic vulcanizates made of nylon and BIMSM are introduced. It not only has excellent flexibility and toughness, but also has excellent air permeability, can be used as a tire liner. Compared with the bromobutyl inner liner, the inner liner can maintain or improve the tire inflation pressure retention, reduce the carcass internal pressure, reduce rolling resistance, reduce tire quality, and improve tire performance.
