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

Embodiment Construction
[0017] The invention provides an asbestos-free organic friction product, which includes a base material, an adhesive layer and a friction layer made of copper-free and asbestos-free organic friction materials. The copper-free and asbestos-free organic friction materials are characterized in that That is, the friction material is composed of the following components in parts by weight: 10-15 parts of bonding material, 45-55 parts of non-copper filler, 3-5 parts of acid-base adjustment material, 5-10 parts of organic fiber, 8 parts of inorganic fiber ~13 parts, non-copper metal fiber or non-copper metal powder 6~15 parts, reinforcing material 0.5~10 parts.
[0018] Wherein, the bonding material is phenolic resin or modified phenolic resin, and the modified phenolic resin is preferably cashew nut shell oil modified phenolic resin or rubber modified phenolic resin. The main component of cashew nut shell oil is phenolic compounds containing unsaturated long chains, which can partia...

The invention relates to a copper-free and asbestos-free organic friction material, which is composed of the following components in parts by weight: 10-15 parts of a binding material, 45-55 parts of a non-copper filler, 3-5 parts of an acid-base adjusting material, and 5 parts of an organic fiber. ~10 parts, 8-13 parts of inorganic fibers, 6-15 parts of non-copper metal fibers or non-copper metal powders, and 0.5-10 parts of reinforcing materials. In the present invention, reinforcing material is added on the basis of the original bonding material, organic fiber and inorganic fiber to ensure the friction coefficient of the friction material is stable, especially the braking stability under low temperature and high speed conditions is better than that of the prior art, Smooth and comfortable, while resisting thermal decay and long 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...
