Preparation method and application of vinyl polyhedral oligomeric silsesquioxane modified styrene-butadiene rubber

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 combine
