Problems solved by technology

The problem is that the elements antimony, zinc, and lead are also non-degradable heavy metals, which not only pollute the environment, but also damage human organs after entering the human body directly or indirectly
In addition, these metal sulfides will oxidize when the brake friction causes high temperature, and the sulfur dioxide released may form acid rain, thus endangering the ecological environment

Embodiment Construction

[0026] 1. A method for preparing an environmentally friendly high-performance friction material for an automobile brake pad:

[0027] S1. Mixing: First put 22-27 parts of reinforcing fiber and 13-24 parts of organic binder into a high-speed mixer and mix until uniform; then add 15-23 parts of calcined kaolin; 1-5 parts of magnesium oxide; 2 -4 parts of alumina; 12-20 parts of barite; 1-3 parts of iron black; 2-6 parts of flake graphite; 2-6 parts of carbon black; 10-15 parts of light calcium carbonate ; 0.2-1 parts of additives are put into a high-speed mixer and fully mixed to obtain a uniformly mixed molding material;

[0028] S2. Drying: Put the molded material in S1 in an electric heating constant temperature blast drying oven for drying treatment, the drying temperature is 95-105°C, and the drying time is 3-4h;

[0029]S3. Hot pressing: add the molding material after drying in S2 into the mold and mold it to obtain the friction plate to be processed. The molding temperat...

Abstract

The invention discloses an environment-friendly high-performance friction material for an automobile brake pad and a preparation method thereof. The environment-friendly high-performance friction material comprises the following raw materials of, by weight, 22-27 parts of reinforced fibers, 13-24 parts of an organic adhesive, 15-23 parts of calcined kaolin, 1-5 parts of magnesium oxide, 2-4 partsof aluminum oxide, 12-20 parts of barite, 1-3 pars of iron black, 2-6 parts of flaky graphite, 2-6 parts of carbon black, 10-15 parts of light calcium carbonate and 0.2-1 part of an assistant. The preparation method of the environment-friendly high-performance friction material comprises the following steps of material mixing, drying, hot pressing and heat treatment. The environment-friendly high-performance friction material and the preparation method thereof have the advantages that asbestos, metal sulfide and harmful heavy metal elements are not added, and the environment friendly effect isachieved; the friction coefficient is stable and moderate, the heat resistance is high, the abrasion rate is low, and braking noise is low; and the preparation technology is simple, easy to operate and suitable for industrial production, and the social and economic benefits are obvious.

Description

technical field [0001] The invention belongs to the technical field of friction materials, and in particular relates to an environment-friendly high-performance friction material for automobile brake pads and a preparation method thereof. Background technique [0002] "Made in China 2025" is the first ten-year action plan for the Chinese government to implement the strategy of manufacturing a powerful country. Among them, the new material technology roadmap is one of the strategic layouts of the ten key areas mentioned, and new materials are divided into three categories: advanced basic materials, key strategic materials and cutting-edge new materials.
