Wear-resistant and anti-ageing automotive rubber damping piece material

Abstract

The invention discloses a wear-resistant and anti-ageing automotive rubber damping piece material. The wear-resistant and anti-ageing automotive rubber damping piece material comprises the following raw materials in parts by weight: 20-30 parts of natural rubber, 20-25 parts of butyl rubber, 10-15 parts of butadiene rubber, 20-25 parts of wear-resistant polyvinyl chloride masterbatches, 4-7 partsof talcum powder, 2-5 parts of a toughener, 2-4 parts of an antioxidant, 1-4 parts of an anti-ageing agent, 1-3 parts of a coupling agent, 3-9 parts of mineral oil, 3-6 parts of a maleic anhydride compatilizer, 3-7 parts of paraffin, 5-8 parts of nano barium sulfate, 2-5 parts of modified nano silicon nitride, 1-3 parts of potassium stearate, 2-5 parts of a promotor, 2-4 parts of a crosslinking agent, 1-2 parts of zinc borate and 3-7 parts of sulphur. The wear-resistant and anti-ageing automotive rubber damping piece material is reasonable in formula, the compatibility of various components isgood, and the prepared damping material has the advantages of high damping coefficient, high resilience force, damping ability, high temperature resistance, ageing resistance, creep resistance, wearresistance, good flame retardant and the like, and is suitable for automotive damping products.

Description

technical field [0001] The invention relates to the field of automobile processing, in particular to a wear-resistant and anti-aging automobile rubber shock absorber material. Background technique [0002] With the rapid development of modern industry, vibration and noise have become serious problems in various fields. It will reduce the operating accuracy, affect product quality, shorten product life, make high-precision instruments not work normally, and endanger safety. [0003] In the processing and manufacturing of automobiles, the shock absorber is one of the essential parts. It is mainly used to suppress the shock when the spring rebounds after absorbing the shock and the impact from the road surface, which plays a role in the comfort and handling stability of the vehicle. important role. The principle of the existing shock absorber bushing is to convert the mechanical energy of vibration into thermal energy through the elastic support and dissipate it to the surroun...

AI Technical Summary

Problems solved by technology

The metal and rubber shock-absorbing bushing has certain performance requirements for rubber, and there is still a lot of room for improvement in the performance of existing rubber products in terms of wear resistance and aging resistance.
