摘要:
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.
摘要:
The present invention relates to the field of tire tread, specifically, relates to a rubber material used for the tire tread with the properties of pricking resistance, and chunking and chipping resistance, its preparation method and the application thereof. The rubber material used for the tire tread in the present invention comprises: (1) 100 parts by weight of main rubber ingredients: including 50-95 parts by weight of natural cis-1,4-polyisoprene rubber and 5-50 parts by weight of synthetic rubber of styrene-butadiene copolymer; (2) compounding agents : based on 100 parts by weight of the main rubber ingredients, the said compounding agents including 10-20 parts by weight of white carbon black used as inorganic filler. The tire tread prepared by the rubber material in the present invention has the tear strength of 110.0Mpa or more and the cutting volume of 0.60cm 3 or below, so that the tire tread has the excellent property of tear resistance so as to further make it have the properties of pricking resistance, and chunking and chipping resistance.
