Abstract

The invention is suitable for the technical field of rubber, and provides nylon rubber for a bushing. The nylon rubber comprises or contains the following components in parts by weight: 100-170 parts of rubber, 4-8 parts of an active agent, 1-3 parts of stearic acid, 2-6 parts of an anti deteriorant, 80-12 parts of a stuffing strengthening agent, 4-10 parts of a softener, 1-2.5 parts of a vulcanizing agent and 1-4 parts of an accelerant. The rubber and the nylon have favorable adhesivity; the fatigue life of products is prolonged. The nylon rubber disclosed by the invention is simple in formula, the hardness of the generated rubber is high, the weariness resistance is high, the deformation rate is reduced, and the density is high.

Description

technical field [0001] The invention belongs to the technical field of rubber, and in particular relates to a nylon rubber used for a bush and a preparation method thereof. Background technique [0002] Rubber bushings in automobile chassis are mainly used in suspension systems to provide flexibility in torsion and tilt, and for axial and radial displacement control. Low axial stiffness has good vibration isolation performance, while high radial stiffness has better stability. From the perspective of product development trends, with the rapid development of China's economy, family cars have gradually entered ordinary families, and the performance requirements for cars are getting higher and higher. The requirements for the comfort of the car are getting higher and higher, and the car chassis is an important shock-absorbing system of the car's shock-absorbing system. The rubber bushing assembly is an important shock-absorbing component of the automobile chassis, which requi...
