Abstract
This invention relates to the technical field of tire. Specifically, the invention relates to oil-proof rubber material for the tire tread and its preparation method and the application thereof. This material is characterized in comprising the following components based on 100 parts by weight: 15-70 parts of natural cis-1, 4-polyisoprene rubber, 0-40 parts of styrene-butadiene copolymer and 15-45 parts of acrylonitrile-butadiene copolymer. The swelling index of the rubber material for tire provided by this invention is 17-25% and the bonding strength is 30-60 kN·m−1, so as to effectively improve swelling resistance and bonding performance. This invention takes both bonding performance and swelling resistance into consideration for the rubber material of the tire tread, and can expand the application scope of rubber material for the tire and has a broadly promising application future.
