Problems solved by technology

In asbestos brake pads, because asbestos has carcinogenic hazards, this type of brake pads is gradually eliminated by the market; and semi-metallic brake pads contain metal substances, which are easy to damage the pair during braking, and there is a large braking force. Hazards also shorten lifespan

Abstract

The invention relates to a method of preparing an automobile brake pad by adopting basalt fiber. The method comprises the following steps: butadiene nitrile rubber modified phenolic resin, surface modified basalt superfine fiber, acicular wollastonite fiber and carbon fiber are added to a material mixing machine and are mixed; then crystalline flake graphite, artificial graphite particles, chromite powder, feldspar powder, dolomite powder, fluorite powder, calcium carbonate powder, mica, nano ZnO, butadiene nitrile rubber and wollastonite are sequentially added to the material mixing machine and mix is carried out; a mixture is placed in a brake pad mould, and hot pressing and demoulding are carried out; a hot pressed material after the demoulding is subjected to grading heat treatment; and a discharged brake pad is subjected to follow-up treatment and packing. The automobile brake pad prepared by the method has a stable friction coefficient and a low wear rate, and further has high heat resistance and heat-aging resistance.

Description

technical field [0001] The invention relates to a method for preparing automobile brake pads by using basalt fibers, and belongs to the field of brake pad preparation. Background technique [0002] Brake pads are the most critical safety braking parts in the braking system of a car. Brake pads play a decisive role in whether the braking effect is good or not. Brake pads are generally composed of steel plates, adhesive heat insulation layers and friction blocks. The heat insulation layer It is composed of materials that do not conduct heat, and the purpose is to insulate. The friction block is composed of friction material and adhesive, which is squeezed on the brake disc or brake drum to generate friction during braking, so as to achieve the purpose of vehicle deceleration and braking. Due to friction, the friction block will be gradually worn, generally speaking, the lower the cost of the brake pads, the faster the wear. After the friction material is used up, the brake p...
