The invention discloses a preparation method and application of vinyl polyhedral oligomeric silsesquioxane modified styrene-butadiene rubber, and belongs to the technical field of rubber material modification. The polyhedral oligomeric silsesquioxane modified styrene-butadiene rubber is a modified polymer with an organic and inorganic hybrid structure and is high in glass transition temperature and excellent in heat resistance, cold resistance and wet skid resistance, vinyl polyhedral oligomeric silsesquioxane is of a Si-O-Si three-dimensional network structure, carbon black and white carbon black can be firmly attached to a polymer matrix, and the high-temperature resistance and the high-temperature resistance are achieved. The friction resistance between the tire and the ground is reduced, and the wear-resisting property is excellent; the vinyl polyhedral oligomeric silsesquioxane contains a large number of vinyl active groups, has good compatibility with other unsaturated rubber, can be organically combined with other auxiliary systems, and has good wet skid resistance and low temperature resistance; when the material is applied to tire tread rubber, the problems of skid resistance, wear resistance, easy tearing at low temperature and the like of automobile tires in low-temperature rain and snow weather can be effectively solved.
乙烯基笼型倍半硅氧烷改性丁苯橡胶的制备方法及应用,该发明属于橡胶材料改性技术领域;笼型倍半硅氧烷改性丁苯橡胶为有机、无机杂化结构的改性聚合物,玻璃化转变温度高,耐热、抗寒,抗湿滑性能优异,其中乙烯基笼型倍半硅氧烷具有Si—O—Si三维网状结构,能够使炭黑、白炭黑牢固附着在聚合物基体上,减少轮胎与地面之间的摩擦阻力,具有优异的耐磨性能;乙烯基笼型倍半硅氧烷含有大量的乙烯基活性基团,与其他不饱和橡胶相容性好,并且能与其他助剂体系有机结合,具有良好的抗湿滑性能和耐低温性能;该材料应用在轮胎胎面胶中能够有效改善汽车轮胎在低温雨雪天气防滑性能、耐磨性能和低温易撕裂等问题。
