Abstract

The invention provides automotive abrasion-resistant damping rubber and preparation method thereof. The preparation method comprises the following steps that 1, natural rubber and polybutadience rubber are added to a mixer for mixing; 2, the rubber material obtained in the step 1, high-abrasion-resistance carbon black N330, zinc oxide, stearic acid, N-isopropyl-N'-phenyl para-phenylenediamine, styrenated phenol, dibenzothiazyl disulfide, tetramethyl thiuram disulfide, polyether urethane modified epoxy resin, polyacrylate toughened and modified epoxy resin, nano silicon carbide, calcium sulfate whiskers and magnesium borate whiskers are added to the mixer for mixing; (3) sulfur is added to the rubber material in the step 2 for mixing again; 4, the rubber material obtained in the step 3 is vulcanized in a vacuumizing and vulcanizing machine. The automotive abrasion-resistant damping rubber has good elasticity, mechanical properties and abrasion-resistant properties.

Description

technical field [0001] The invention relates to the field of rubber materials, in particular to a wear-resistant and shock-absorbing rubber for automobiles and a preparation method thereof. Background technique [0002] With the development of social economy, the modification and replacement of domestic and foreign automobiles is quite frequent, and the automobile industry is facing a period of rapid change. The development is characterized by ensuring driving safety, riding comfort, high-speed driving and luxury. , Further improve the service life of the car. Shock-absorbing products are used to control the vibration and noise of the car and improve its handling stability. They are generally placed in the car engine frame, pressure bar device, suspension bushing, center bearing bracket, jolt limiter and torsional shock absorber. , to improve the safety and comfort of the car. Shock-absorbing products can be divided into four categories: brackets, bushings, cushioning and ...
