Effect test

experiment example 1

[0060] Use the same test conditions to test the coefficient of friction, compressive strain, impact strength, weight loss after the AK-MASTER test, and whether there are cracks on the surface after the test of the X1 prepared in the comparative example and the composition of Examples 1-6. See Table 2 for specific data comparison.

[0061] The X1 that table 3 comparative example makes and the performance effect data of the composition of embodiment 1-6

[0062]

[0063] As can be seen from Table 2, the performance of the high-strength heat-resistant rubber-based composition for automobile brake pads provided by the present invention is significantly better than that of X1, which may be due to the fact that each component in the composition of the present invention produces In order to realize the effect of synergy, it is found through comparative data that the nominal friction coefficient of the X1 formula is 0.45, which is relatively high, and the thermal recession coeffici...

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...
