Problems solved by technology

This invention uses boron-modified phenolic resin as binder, short carbon fiber as reinforcing phase, and adds a variety of inorganic substances as fillers. The synergistic effect of multiple components makes the metal-free boron-modified phenolic resin-based friction plate have excellent wear resistance. and high hardness, but its high temperature resistance is poor
Therefore, although the prior art has realized the braking effect of the brake pads, the current automobile brak

Abstract

The invention discloses a preparation method for a friction plate. Materials of the friction plate comprise an enhanced titanium alloy skeleton and filler. The enhanced type titanium alloy skeleton comprises titanium alloy powder, tungsten carbide and titanium hydride. The filler comprises graphene fiber, diatomite, brass powder, graphite, carbon fibers, silicon dioxide, Pbo fiber, adhesive spraying aluminum silicate fiber, nanometer phenolic resin, styrene butadiene rubber, aramid fiber, mineral fiber, copper fiber, polypropylene fiber, paper fiber, metallic aluminum powder, zinc powder, mica, calcined petroleum coke, red vermiculite, light magnesium oxide, precipitated barium sulfate, light calcium carbonate, modified phenolic resin, molybdenum powder, molybdenum disulfide, graphite, nitrile butadiene rubber, ferric oxide, chromium oxide and the like; and the four technological processes of burdening, mixing and stirring, hot pressing forming and curing are adopted to complete the preparation method for the friction plate. The friction plate prepared through the scheme is low in hardness, high in stability, low in noise generated when an automobile is used and good in safety performance.

Description

technical field [0001] The invention relates to the technical field of automobile braking, in particular to a friction plate. Background technique [0002] Automobile braking system refers to a series of special devices that exert a certain force on certain parts of the automobile (mainly the wheels) to perform a certain degree of mandatory braking. Automobile braking system is a key system that affects the safety of automobiles, and the stability and reliability of the braking system are directly determined by the comprehensive performance of the friction pads (especially the brake pads). [0003] Conventional brake pads are divided into: 1. Asbestos type. Because asbestos fiber has the characteristics of high strength and high temperature resistance, it meets the requirements of brake pads and clutch discs. It also has the tensile strength of fibers and the hardness and wear resistance of advanced metal materials. 2. Semi-metallic type, which mainly uses rough steel wool ...
