Abstract

The invention provides a friction material, a long-life friction lining and a preparation method thereof. The friction material comprises the following raw materials, by weight, 5-8 parts of basalt fiber; 10-15 parts of steel fiber; 5-6 parts of composite mineral fiber; 6-10 parts of butyronitrile modified phenolic resin, 3-8 parts of powdered acrylonitrile-butadiene rubber, 5-9 parts of graphite,10-15 parts of precipitated barium sulfate, 2-5 parts of aramid pulp, 2-5 parts of titanate lamellar crystals, 9-15 parts of light calcium carbonate, 7-12 parts of magnesium oxide, 3-6 parts of calcined aluminum oxide, 5-8 parts of red copper fibers, 5-9 parts of ferrous sulfide and 9-12 parts of fluorite. By reasonably setting the content of each component, the components generate a synergisticeffect, when the components are proportioned together to be used for the friction lining, it is confirmed through loading test and verification that the service life of the friction lining reaches 120,000 km or above, and the friction lining is complete and free of edge and corner falling, delaminating and scorching phenomena.

Description

Technical field [0001] The invention relates to the field of brake materials, in particular to a friction material, a long-life friction lining and a preparation method thereof. Background technique [0002] Friction material is a component material that is used in power machinery and relies on friction to perform braking and transmission functions. It is mainly used in various equipment brakes, clutches and braking materials in friction transmission devices to make mechanical equipment and Various motor vehicles can work safely and reliably. The main composite components of friction materials are binder, reinforcing fiber and friction performance modifier. Reinforcing fibers mainly make the friction material have certain strength and toughness. Friction performance modifiers include friction-increasing materials and friction-reducing materials, which are used to adjust friction materials. The adhesive is used to bond the components of the friction material into a whole, and the...
