Problems solved by technology

During the braking process of the car, the friction lining will wear out, one of which will cause dust pollution to the road surface; the second is that in the braking system, the dust generated by the friction lining wear is mixed in it, causing the friction lining to wear faster, and in severe cases Even cause the friction plate to lock the brake pad and cause a car accident

Abstract

The invention aims to provide a friction material having high cleaning performance while having high friction coefficient and safety performance and a friction plate preparation method. The friction material comprises, by weight percentage, 4-10% of resin, 6-10% of coke dust, 0.5-5% of nitrile powder, 1-8% of tire powder, 1-4% of corundum, 9-20% of graphite, 1-3% of iron black, 1-3% of activated carbon, 2-5% of friction powder, 20-30% of fiber and 30-55% of packing. The method for preparing a friction plate by utilizing the materials comprises a step (1) of mixing the materials: manufacturing a friction material mixed material; a step (2) of performing prepressing: preforming the mixed material; a step (3) of performing hot pressing: placing pressed blank in a die to undergo hot pressing, and performing interval exhaust-gas disposal; a step (4) of performing heat treatment: performing constant-speed warming and thermal insulation in a graded manner from room temperature to 185 DEG C; and a step (5) of performing size processing. The friction material is applied to the field of friction materials.

Description

technical field [0001] The invention relates to a friction material, in particular to a safe friction material with high cleaning performance for automobile brake discs and a preparation method of a friction plate. Background technique [0002] With the progress of the times, people's living standards continue to improve, and the pursuit has increased from the initial satisfaction with food and clothing to the pursuit of material, and then the minimum requirements for all aspects have been raised to a higher level. Now the streets are full of cars. With the rapid growth of car ownership, car pollution problems have emerged within the scope of people's realization, including their emissions and noise pollution. Among them, in the braking system applied to automobiles, the friction plates are made of non-metal. During the braking process of the car, the friction lining will wear out, one of which will cause dust pollution to the road surface; the second is that in the brakin...
