Problems solved by technology

[0005] The thermal stability of the existing solid wheel rubber is not ideal, and it is difficult to adapt to the high-speed, high-load application environment. Therefore, it is necessary to increase the modulus and heat resistance of the rubber material by adding high-temperature-resistant and wear-resistant carbon fibers, but directly Addition often leads to a decrease in the bonding strength between rubber and metal components, and the existing modification technology of carbon fiber usually cannot take into account the bonding performance of rubber materials and metal components

Abstract

The invention relates to the field of special vehicle solid wheel rubber materials, in particular to a special vehicle solid wheel rubber based on modified chopped carbon fibers and a preparation method thereof. Specifically, using natural rubber as the main polymer, the chopped carbon fiber is modified by coating the chopped carbon fiber with zinc acrylate, and compounded with carbon black, white carbon black and thermally conductive fillers to prepare special vehicle solid wheel rubber materials. Compared with the prior art, the invention improves the elasticity and thermal stability of the solid wheel rubber of special vehicles and improves the bonding stability between the solid wheel rubber and the metal surface under the premise of maintaining the mechanical properties and load-carrying properties of the rubber material .

Description

technical field [0001] The invention relates to the field of solid tire rubber materials, in particular to a special vehicle solid wheel rubber based on modified chopped carbon fibers and a preparation method thereof. Background technique [0002] The solid wheels of special vehicles generally refer to the solid tires of tracked tank armored vehicles, and can also be the solid wheels of the running wheels of empty rail trains. [0003] The solid wheels of the tracked special vehicle are assembled on the metal track of the tracked vehicle, and roll with the track to support the car body and absorb shock. The rubber material of the solid wheel of tracked special vehicles is used under harsh conditions, requiring high modulus, high load, high elasticity, thermal stability under cyclical stress and strain, and stable bonding performance with metal parts. [0004] Carbon fiber is a high-strength, high-modulus, high-temperature-resistant, and fatigue-resistant fiber material with...
