Abstract

The invention discloses a high-strength heat-resistant rubber-based composition for automobile brake pads, an application and a preparation method thereof, and relates to the technical field of preparation of automobile brake pads. The formula of the high-strength heat-resistant rubber-based composition for automobile brake pads provided by the invention contains a high-component reinforcing whisker material and a coumarone resin material used in conjunction. The high-strength heat-resistant rubber-based composition for automobile brake pads provided by the invention solves the problem that the high heat generated during the braking process easily causes thermal recession of existing rubber-based brake pads, leading to brake failure and endangering life safety.

Description

technical field

[0001] The invention relates to the technical field of preparation of automobile brake pads, in particular to a high-strength heat-resistant rubber-based composition used for automobile brake pads. Background technique

[0002] With the rapid development of automobile industry and transportation at home and abroad, on the one hand, the high growth rate has provided a market for friction material products; on the other hand, the increase in vehicle speed has put forward more stringent requirements for the performance of friction materials. The first is the requirement of environmental protection; the second is to have a good friction coefficient and wear resistance, with a certain heat resistance and mechanical strength; the last is to meet the market requirements, to ensure the performance and develop lower cost brake pad formula more and more become a trend.

[0003] Automobile brake pads are an important part to ensure the safety of automobiles. The worki...
