Problems solved by technology

[0004] However, with the improvement of people's requirements for braking performance and environmental performance of brake pads, traditional brake pad friction materials contain heavy metal components, such as copper, etc., so it is urgent to study a brake pad friction material that does not contain heavy metals. The problem

Abstract

The invention discloses a friction material for a brake pad, which is characterized by comprising Calder lai resin, Twaron fibre, glass fiber, mineral fiber, graphite, molybdenum dioxide, meerschaum, barium sulfate, friction powder, tyre powder, friction adding agent, potassium feldspar, flame retardant and zircon sand. Through the steps of the mixing the raw materials, grinding the raw materials, hot pressing process and shaping process, the preparation of the friction material for the brake pad is finished, so that the friction material for the brake pad with good environmental protection performance and high abrasion resistance coefficient is obtained.

Description

technical field [0001] The invention belongs to the brake pad industry and relates to a brake pad friction material and a preparation process thereof. Background technique [0002] Brake pads are the most critical components in the braking system. The moving parts are locked by the brake pads, but the quality of the brake pads determines the braking effect. The brake pads are installed on the steel plate of the brake, and the friction material is bonded to the steel plate with an adhesive, so that when braking, the friction material is used to resist the moving parts, so that there is friction between them and the moving parts, so that the brake is installed Vehicles or equipment, etc. slow down, or even lock up. However, the quality of the friction material is closely related to the braking effect of the brake. [0003] Friction materials are usually composed of four parts: reinforcing materials, adhesives, fillers and friction modifiers. Adhesives are an important part o...
