Abstract

The present invention discloses a calcium carbonate whisker reinforced resin-rubber base friction material, and a preparation method therefor. The material comprises: 10-15 parts of liquid nitrile rubber-modified phenolic, 5-10 parts of styrene-butadiene rubber, 0-25 parts of calcium carbonate whisker, 10-20 parts of steel fiber, 0-8 parts of sepiolite fiber, 0-8 parts of mineral fiber, 0-3 parts of aramid fiber, 5-8 parts of barium sulfate, 5-10 parts of magnesium oxide, 2-3 parts of aluminum oxide, 5-10 parts of flake graphite, 1-5 parts of carbon black, 5-10 parts of petroleum coke, and 3-7 parts of friction powder. The preparation method of the calcium carbonate whisker reinforced resin-rubber base friction material comprises steps of such as material collocation, ban burying, crushing, pressing molding, immobilization processing, cooling, and packaging. Brake pads prepared by the invention, tested by an MM1000-III type friction and wear testing machine, have excellent friction and wear performance and stable braking performance, is safe and environmentally-friendly, and also has the advantages such as good stability of friction coefficient, low wear rate and high heat-resistant property.

Description

technical field [0001] The invention relates to the technical field of traffic materials, in particular to a calcium carbonate whisker reinforced resin-rubber-based friction material and a preparation method thereof. Background technique [0002] Friction materials are functional accessories used in many sports machinery and equipment for transmission, braking, deceleration, steering, parking, etc. Friction materials are widely used in various means of transportation, such as brake pads and clutch pads of automobiles, trains, airplanes, ships, etc., and various machinery and equipment. Converted to heat and other forms of energy to brake the transmission. Cars are the main means of transportation for people to travel, and the braking materials in the car braking system directly affect the safety performance of the car. The main problems of the automobile brake pads currently used in the market are poor stability of friction coefficient, low heat resistance, and a series of...
