Organic friction material containing no copper or asbestos and product

Abstract

The invention relates to an organic friction material containing no copper or asbestos. The material comprises the following components including, by weight, 10-15 parts of a binding material, 45-55 parts of non-copper packing, 3-5 parts of an acid-base adjusting material, 5-10 parts of organic fiber, 8-13 parts of inorganic fiber, 6-15 parts of non-copper metal fiber or non-copper metal powder and 0.5-10 parts of a reinforced material. According to the organic friction material provided by the invention, the reinforced material is added on the basis of the binding material, the organic fiber and the inorganic fiber, it is guaranteed that the friction coefficient of the friction material is stable, the braking stability is better than that in the prior art particularly under low-temperature and high-temperature working conditions, the friction material is stable and comfortable, and meanwhile, the organic friction material is resistant to thermal decay and long in service life.

Description

technical field [0001] The invention relates to the technical field of friction materials, in particular to a copper-free and asbestos-free organic friction material and its products. Background technique [0002] Friction material is a component material used in power machinery that relies on friction to perform braking and transmission functions. It includes organic friction materials, powder metallurgy friction materials, and paper-based friction materials by type. Among them, organic friction materials are mainly composed of three categories, including binders, fillers and fiber reinforced materials. [0003] The main components of copper-containing organic friction materials on the market are generally phenolic resin, fiber materials, filler materials, and metal materials mainly brass and copper. On the one hand, a small amount of copper-containing materials will be deposited on the road after each brake. Finally, it flows into the waterway and poses a threat to rivers...

Problems solved by technology

[0003] The main components of copper-containing organic friction materials on the market are generally phenolic resin, fiber materials, filler materials, and metal materials mainly brass and copper. On the one hand, a small amount of copper-containing materials will be deposited on the road after each brake. Finally, it flows into the waterway and poses a threat to rivers and marine life. The United States and other countries have taken the lead in considering banning the use of copper in friction materials; reduce a lot, and the instability of the friction coefficient can easily lead to driving accidents
