Abstract

The invention relates to a halide-containing brake material and a preparation method and application thereof, and belongs to the technical field of brake materials. The preparation method comprises the following steps: adding aromatic alcohol phenolic resin, butadiene rubber, feldspar powder, argil, kaolin, calcined petroleum coke powder and halide into a mixer according to a proportion, mixing and stirring for 20-25min, then adding carbon fibers, potassium titanate whiskers and magnesium borate whiskers according to a proportion, and mixing and stirring for 12-18min until the mixture is uniform to obtain the halide-containing brake material; and placing a steel backing and the brake material into a mold for compression molding, placing the mold into an oven for heating and curing after demolding, and finally machining to obtain an automobile brake pad or a rail transit vehicle brake pad. The friction material of the automobile brake pad and the rail transit vehicle brake pad is particularly suitable for a brake disc with a dual material being aluminum alloy, the porosity of a microporous material is large, the hardness is low, and damage to the brake disc is reduced. The microporous material and the aluminum alloy brake disc are high in heat dissipation speed, the working temperature of a friction pair can be reduced, and the friction pair can bear larger load.

Description

technical field [0001] The invention relates to the technical field of brake materials, in particular to a halide-containing brake material and its preparation method and application. Background technique [0002] Lightweight is the development trend of automobiles in my country. It is very important to reduce the weight of vehicles. Brake discs are part of the unsprung mass of vehicles. Reducing the mass of brake discs can not only reduce emissions and pollution, but also further reduce vibration and noise. , Improve ride comfort, etc. At present, the existing automobile brake discs are cast iron discs, and their mass is relatively large, while silicon carbide reinforced aluminum alloy brake discs have the advantages of small density, light weight, and fast heat dissipation, which will definitely be a development trend of automobile lightweight, especially For new energy vehicles, after using aluminum alloy brake discs, the unsprung weight of each vehicle can be reduced by ...
