AI Technical Summary

Problems solved by technology

Its disadvantages are: 1. Asbestos fibers may cause lung cancer
The disadvantages are: 1. Higher braking pressure is required to achieve the same braking effect; 2. Especially in low temperature environments, the high metal content will cause greater wear and tear on the brake disc, and at the same time will generate greater noise; 3. Braking The heat is transferred to the brake caliper and its components, which will accelerate the aging of the brake caliper, piston seal and return spring; 4. Improper heat treatment reaches a certain temperature level, which will cause brake shrinkage and brake fluid boiling

The automobile brake block comprises components in parts by weight as follows: 5-10 parts of a phenolic resin, 5-10 parts of a modified resin, 3-5 parts of poly-para-phenylene terephthalamide fibers; 8-10 parts of glass fibers, 5-12 parts of graphite, 3-5 parts of sepiolite fibers, 3-5 parts of steel fibers, 2-3 parts of aramid fibers, 3-5 parts of antimony trisulfide, 10-15 parts of calcium carbonate, 2-5 parts of mica, 2-5 parts of vermiculite, 8-10 parts of steel wool, 5-10 parts of red copper wool, 15-20 parts of molybdenum sulfide, 10-15 parts of barium sulfate, 8-10 parts of molybdenum trioxide, 10-12 parts of feldspar powder, 10-20 parts of aluminum silicate hollow spheres and 3-5 parts of friction powder. A method for processing the automobile brake block comprises the steps as follows: burdening, hot briquetting, heat treatment, grinding and spraying, wherein the heat treatment is performed as follows: a heat treatment device adopts a heat treatment box, the treatment temperature is 150 DEG C-180 DEG C, and the time is 4-8 h.

Description

technical field [0001] The invention relates to an automobile brake pad, in particular to an automobile brake pad and a preparation method thereof. Background technique [0002] The braking system is an important safety system in the car, and the braking components will directly affect the reliability of the entire braking system. [0003] Brake pads are the original parts under high pressure in vehicles. The basic quality requirements of brake pads are: wear resistance, large friction coefficient, and excellent heat insulation performance. According to different manufacturing materials, brake pads can be divided into three types: asbestos pads, semi-metallic pads, and NAO (non-asbestos organic) pads. [0004] Asbestos-type brake pads: 40%-60% of its composition is asbestos. The main advantage of asbestos sheets is that they are cheap. Its disadvantages are: 1. Asbestos fibers may cause lung cancer. Does not meet modern environmental protection requirements; 2. Asbestos...
