Bead wear-resistant rubber composition and mixing method thereof and tire

Abstract

The invention relates to the technical field of new materials for manufacturing car tires, and in particular, relates to a bead wear-resistant rubber composition and a mixing method thereof and a tire. According to the bead wear-resistant rubber composition, the lagging loss of a rubber material is reduced by adopting butadiene rubber B; styrene butadiene rubber is adopted to improve carbon black dispersion so as to reduce lagging of the rubber material; the lagging of the rubber material is reduced by reducing the dosage of a filling reinforcing agent; the wear resistance is improved by adopting a high-wear-resistance carbon black reinforced rubber composition; by adopting the lignocellulose reinforced rubber composition, the modulus can be improved, and the permanent deformation can be reduced; and an organic sulfur donor is adopted to reinforce the bead wear-resistant rubber composition, so that the anti-reversion performance is improved, the modulus of the rubber material is improved, the compression permanent deformation is reduced, the compression temperature rise is reduced, the lag of bead wear-resistant rubber is reduced, the control of the tire is improved, and the rolling resistance of the tire is reduced.

Description

Technical field [0001] The present invention relates to a passenger tire manufacturing technology and new materials, and particularly to a wear-resistant rubber composition for clinch and a tire and kneading method. Background technique [0002] Plant for the rolling resistance of automobile tires more demanding, the tire from the tread formulators, sidewall, carcass and other components, much research to reduce hysteresis desired compound, thereby reducing the tire rolling resistance. Wear-resistant plastic bead rim in direct contact with the vehicle, wear-resistant plastic bead requires permanent deformation of high modulus, high wear resistance, low compression, low hysteresis characteristics. [0003] Chinese Patent Application (Publication number: CN105924696A, Publication date: 20160907) describes, using the short fiber reinforcing rubber dipped nylon reinforced plastic bead, can significantly improve the strength of the glue bead, tear resistance and creep , lower radial b...
