Embodiment Construction

[0044] A: Examples of Changan passenger car disc brake pads:

[0045] ①According to the following formula ingredients:

[0046] Phenolic resin 9%; steel fiber 12%; brass fiber 5%; copper fiber 3%; aramid fiber 3%; glass fiber 5%; silica fume 6%; artificial graphite 5%; natural graphite 5%; ferrochrome 8% ore; 8% pyrite; 5% magnetite; 4% antimony sulfide; 10% barium sulfate; 5% dolomite; 3% calcium fluoride; 4% kaolin;

[0047] ② Use a vertical mixer for mixing to ensure that the ingredients are evenly distributed;

[0048] ③Use a hot press and specific tooling and molds to place the mixture in a mold according to a certain weight and press it into shape;

[0049] ④ Use a high-power oven to cure the phenolic resin;

[0050] ⑤ Carry out follow-up machining on the heat-treated product according to the drawing requirements;

[0051] ⑥ Packing and storage.

[0052] B: Example of Dongfeng Motor EQ153 drum brake pad

[0053] ① Formula:

[0054] Phenolic resin 15%; steel fiber ...

Abstract

This invention relates to a preparation technology for producing special products with plastic substances characterizing in mixing an adhesive agent, strengthened fibers, a regulator for friction performance and inorganic fillers in good match to process the surfaces of them with an anti-high temperature coupler to be hot-pressed to a format to get a high performance car brake plate of environmental protection, which replaces that made of asbestos fiber and overcomes the shortcoming of declining at high temperature of the asbestos car brake plates.

Description

Technical field: [0001] The present invention relates to the production of special products with substances in plastic state, specifically automobile brake materials and its preparation process. 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. Automobile brake pads made of asbestos, in the high temperature state (about 300 ℃) generated after emergency braking, the friction coefficient will be seriously reduced, resulting in serious degradation of braking torque, affecting driving safety; and short service life, frequent replacement , which not only leads to high operating costs, but also dehydrated asbestos dust formed under high temperature wear, which has a strong carcinogenic effect on the human body and pollutes the environment. Invention content: [0003] The object of the...
