Embodiment 1

[0018] A modified friction material with excellent performance, including the following components in parts by weight: 60 parts of isoprene rubber, 10 parts of glass fiber, 10 parts of composite fiber, 5 parts of polypropylene, 5 parts of silicone oil, 10 parts of corn stalk activated carbon powder, 5 parts of talcum powder, 5 parts of molybdenum disulfide, 2 parts of flame retardant and 1 part of vanadium trioxide.

[0019] The corn stalk activated carbon powder is a carbon powder obtained after successively washing and drying corn stalks, crushing and pressing into blocks, carbonization treatment and graphitization treatment. The carbonization treatment specifically includes: put the corn stalks into the oxygen-poor furnace for carbonization treatment; during the dehumidification period, the temperature rises from ignition to 150°C for 5 hours; then the temperature is raised to 250°C, the blower is turned on, and the furnace Internal blowing, the primary carbonization time i...

Abstract

The invention discloses a modified friction material with excellent performance. The modified friction material comprises, by weight, 60-70 parts of isoprene rubber, 10-20 parts of fiber glass, 10-20 parts of composite fibers, 5-10 parts of polypropylene, 5-10 parts of silicone oil, 10-15 parts of cornstalk activated carbon powder, 5-10 parts of talcum powder, 5-10 parts of molybdenum disulfide, 2-5 parts of fire retardant and 1-2 parts of vanadium trioxide. The invention has the advantages that compositional formulas of current friction materials are re-optimized, side products of corn---cornstalks are fully utilized, and the cornstalks are carbonized and graphitized into the activated carbon powder which substitutes for natural graphite powder to be added into the friction material, so that production cost of the friction material is reduced effectively, utilization channels of the cornstalks are widened, and economic benefit of the cornstalks is improved.

Description

technical field [0001] The invention relates to a modified friction material with excellent performance. Background technique [0002] Friction materials are widely used in various transportation vehicles (such as automobiles, trains, airplanes, etc.) and brakes, clutches and friction transmissions of various mechanical equipment. According to the function and installation position, it is mainly divided into brake lining and clutch facing. Friction materials are key safety parts in the automobile industry. The starting, braking and parking of automobiles are inseparable from friction materials. It goes without saying. But there are some defects in traditional automobile friction materials, such as asbestos automobile friction materials, because asbestos is a kind of natural mineral fiber, it has high heat resistance and mechanical strength, but asbestos has certain dangers to human health. Therefore, people began to study friction materials without adding asbestos, adjust...
