Abstract

The invention discloses a rubber material for wear-resistant tires. The rubber material is prepared from the following components in parts by weight: 100 parts of cyano-thiofluoroborosilicone rubber,40-50 parts of modified epoxidized polybutadiene, 5-10 parts of molybdenum disulfide nanofibers and 15-20 parts of nanometer ZSm-5 molecular sieves. A preparation method of the rubber material for thewear-resistant tires comprises the following steps: putting the cyano-thio-fluoro-boro-silicone rubber and the modified epoxidized polybutadiene into an internal mixer according to the ratio for banburying for 12-18min, and then adding the molybdenum disulfide nanofibers for mixing for 5-8min; finally, adding the nanometer ZSm-5 molecular sieves for continuously mixing for 3-5min, and then discharging into a rough shape cutting machine for slicing so as to obtain the rubber material for the wear-resistant tires. Compared with rubber in the prior art, the rubber material, disclosed by the invention, for the wear-resistant tires, is more excellent in road holding property, temperature resistance, wear resistance, weather resistance and fire resistance, higher in strength and better in resilience.

Description

technical field [0001] The invention relates to the technical field of rubber compounds, in particular to a rubber material for wear-resistant tires and a preparation method thereof. Background technique [0002] Tires are ground-rolling circular elastic rubber products assembled on various vehicles or machinery. They are one of the important parts of vehicles. They are usually installed on metal rims and directly in contact with the road surface. The impact of the situation, to ensure that the vehicle has good ride comfort and ride comfort, to ensure that the wheels and the road have good adhesion, and to improve the traction, braking and passability of the vehicle. The performance of a tire is determined by its rubber material, which directly affects the safety and comfort of the wheel. The demand for materials for tires is increasing, and people have put forward new requirements for them, not only requiring them to have higher load-bearing performance, traction performan...
