Problems solved by technology

[0003] Now common brake pad materials mainly include semi-metallic friction materials and NAO friction materials, among which semi-metallic friction material brake pads will produce heavy metals and have large braking noise during use, which will have adverse effects on people's health; NAO friction materials Aramid fiber, carbon fiber, ceramic fiber, mineral fiber, etc. are mainly used as reinforcing fibers, but due to the complicated and difficult processing technology and high cost, most of our country relies on imports to meet domestic demand

Abstract

The invention provides a friction block in a brake pad. The friction block is prepared from phenolic resin or boron modified phenolic resin or melamine modified phenolic resin, nitrile butadiene rubber powder, lignin fiber, activated carbon, expandable graphite, molybdenum disulfide, barium sulfate, calcium carbonate, calcium sulfate whisker, iron oxide yellow, aluminum oxide, red ferric oxide powder, silicon carbide, wollastonite, vermiculite powder and high abrasion furnace black. The invention further provides a preparation method of the friction block based on the component formula. The preparation method conducts ingredient strengthening and technology strengthening for the friction block, ingredient strengthening and technology strengthening realize powerful combination, and therefore the comprehensive performances comprising the friction coefficient, hardness, wear-resisting property, impact toughness, heat-conducting property, resistance to high temperature and corrosion resistance of the friction block in the brake pad are improved so as to meet the use requirements under the high-load, high-temperature, high-speed and high-corrosive environment. The invention further provides the brake pad comprising the friction pad.

Description

technical field [0001] The invention relates to the technical field of friction materials, in particular to a friction block, a preparation method thereof, and a brake pad. Background technique [0002] With the rapid development of my country's economy and automobile industry, cars have entered more and more families, and the number of cars in my country has exceeded 300 million and is still growing. The performance of brake pads directly affects the safety of cars and passengers.
