Problems solved by technology

[0005] 2. Decay performance: In the downhill conditions of mountain roads, the brakes brake continuously, the temperature rises rapidly, the braking ability of the brake pads will become worse, and the braking distance will increase
Once the discs come off during the driving of the vehicle, it will lead to the failure of the braking system and cause serious consequences.

Abstract

The invention provides a manufacturing and testing process for an automobile brake block. The manufacturing and testing process for an automobile brake block comprises the following steps of weighing the following components in parts by weight: 9 parts of phenolic resin, 6 parts of carbon fibers, 7 parts of red copper fibers, 6 parts of copper scraps, 10 parts of friction dust, 6 parts of nitrile rubber and 6 parts of mineral-reinforced fibers, and sequentially stirring and uniformly mixing the components; additionally weighing the following components in parts by weight: 8 parts of barite, 6 parts of cokes, 5 parts of high-carbon artificial graphite, 6 parts of zirconium oxide, 7 parts of white vermiculite, 3 parts of aramid, 7 parts of antimony sulfide and 8 parts of alpha aluminum oxide, and uniformly stirring and mixing the components; placing the mixed materials in the step 1 and the step 2 in a stirring device for stirring; weighing a finally mixed material according to pieces, and hot pressing the pieces at the temperature of 150 DEG C for forming; treating a pressed friction material product with a heat treatment process for 3h at the temperature of 200 DEG C, and sequentially carrying out grinding and plastic spraying on the treated friction material product to prepare the brake block; and carrying out timely and accurate shearing strength and compressive resistance capability tests on the prepared brake block to ensure that the prepared brake block accords with the safety requirements.

Description

technical field [0001] The invention belongs to the field of brake pad manufacturing, in particular to a manufacturing and testing process of an automobile brake pad. Background technique [0002] With the increase of vehicle speed, load capacity, and environmental protection awareness, the automotive industry has also put forward higher and higher requirements for the comprehensive performance of brake pads. [0003] There are many performance indicators of brake pads. The performance of the same brake pad is very different under different temperatures, different speeds, different braking pressures, etc. The main performances are as follows: [0004] 1. Braking performance; refers to the braking capacity (friction coefficient) of the brake pads under normal braking conditions (that is, when the braking temperature is relatively low); [0005] 2. Fading performance: In the downhill conditions of mountain roads, the brakes brake continuously, the temperature rises rapidly, t...
