Abstract

The invention discloses a graphene-containing tire tread composite material. The rubber material comprises the following components in parts by mass: 1 to 20% of graphene or composite material of graphene, 50 to 80% of rubber-like material, and the balance of auxiliary material, wherein the rubber-like material comprises SSBR (solutionpolymerized styrene butadiene rubber) and hybride thereof, or mixture with one or multiple of SBS (styrene-butadiene-styrene), SEBS (styrene-ethylene-butylene-styrene) and SEPS (styrene-ethylene / propylene-styrene). The graphene-containing tire tread composite material has the advantages that by mixing the graphene material into the tire rubber material, the uniformly dispersed graphene material is bonded with the tire rubber material, and is intercalated anddistributed in a network-like structure, so that the novel tread rubber material is obtained, thereby improving the abrasion-resistant property and heat-resistant property of a tire, and improving thesafety property in driving; the tire rubber material uses the hydrogenated SSBR as the core component, the different hydrogenation degrees of SSBR are controlled, and the different formula componentsare utilized, so as to form the composite main material of the rubber material, thereby realizing the highly-elastic damping property of the tread, and also realizing the anti-ultraviolet property, anti-aging property and abrasion-resistant property; the graphene-containing tire tread composite material can be recycled, so that the green and environment-friendly effects are realized, and the energy-saving and emission-reduction properties are realized.

Description

technical field [0001] The invention relates to a tire tread composite material, in particular to a tire tread composite material containing graphene, and belongs to the technical field of tire formula. Background technique [0002] In recent years, the domestic shared bicycle industry has developed rapidly, and many emerging companies have been born in a short period of time, followed by intensified market competitiveness. The market has higher and higher requirements for shared bicycles, and the standards for corresponding vehicle tires have also risen. In particular, the emergence of shared electric vehicles has deepened people's understanding of the wear resistance of shared bicycle tires and the safety performance of high-speed driving. There are serious deficiencies in abrasive performance and frictional heat generation. [0003] In fact, materials suitable for bicycle tires include traditional rubber, thermoplastic elastomer materials, etc. Traditional rubber treads ...
