Abstract
The invention relates to a method for preparing a car brake pad with silicon dioxide in the field of friction materials, and provides a friction material, which is fine in safety and high in performance. The brake pad is prepared with a silicate hollow ball, resins, fibers, friction increasing agents, antifriction agents, friction conditioning agents and filling agents according to the process steps of distributing, mixing, cold forming, vulcanizing, grinding and checking, wherein the antifriction agents are graphite, the friction conditioning agents are friction powder, the resins are butyronitrile modified resins, the fibers are formed by blending short aramid fibers, ceramic fibers and copper fibers, the friction increasing agents are formed by blending zircon and iron black, and the filling agents are formed by blending barium sulfate, potassium titanate and tire powder. The car brake pad prepared by the technical method passes inspection through the TP2044 standard of an American LINK3900 rack, is stable in safety performance, and has the advantage of low cost. In addition, an existing machining process does not need to be modified by the technology, and production and modification costs are greatly saved.
Description
Technical field
The silica that utilizes that the present invention relates in the friction material field prepares the method for brake pad of car.
Background technique
Brake block prepares and generally includes following component in the process: resin, fiber, increase grinding agent, anti-friction composition, friction modifier, bulking agent.Its processing technology mainly comprises batching-batch mixing-cold mould-sulfuration-grinding-check-packing.Use new material to reduce cost is the major issue that the friction material industry is advocated always, and production security is good, and the brake pad of car friction material that cost is low is imperative especially.
Summary of the invention
The object of the invention is exactly to the existing existing present situation of brake pad of car, provides a kind of Security good, the automobile brake sheet friction material that performance is high.To achieve these goals, the present invention furthers investigate and comparative trial around the following aspects emphatically: the one, and the selection of resin and application; The 2nd, fiber, the selection that increases grinding agent and filler material and application; The 3rd, carry out combinatory analysis and test contrast around all material proportion scale; The 4th, the rational Match of new material and existing technology etc.Proposing following its technological scheme on this basis is: the silicate composite material brake block, and be with silicate hollow spheres, resin, fiber, increase grinding agent, anti-friction composition, friction modifier and bulking agent and make by following process step, batching-batch mixing-cold mould-sulfuration-grinding-check, anti-friction composition wherein is a graphite; Friction modifier is the friction powder, and described resin adopts butyronitrile modified resin, and fiber adopts aramid fiber short fibre and ceramic fiber, copper fiber to be mixed; Increase grinding agent and adopt zircon and iron oxide black to be mixed, bulking agent adopts barium sulphate and potassium titanate, tyre talc to be mixed, and various raw-material weight portions are respectively in the blending process; Silicate hollow spheres 1-10, resin 5-15, aramid fiber short fibre 2-10; Ceramic fiber 10-20, copper fiber 5-15, zircon 1-2; Iron black 1-3, graphite 1-10, friction powder 3-10; Barium sulphate 20-30, potassium titanate 15-25, tyre talc 2-4.Various raw-material optimum weight part proportionings are in the blending process, silicate hollow spheres 8, resin 8, aramid fiber short fibre 3, ceramic fiber 15, copper fiber 10, zircon 1, iron oxide black 1, graphite 8, friction powder 4, barium sulphate 25, potassium titanate 14, tyre talc 3.Adopt the brake block of technological method preparation of the present invention, qualified through U.S. LINK3900 stand TP2044 standard detection, this brake pad of car Safety performance is stable, and has the low advantage of cost.Should technology not need existing processing technology is improved in addition, practiced thrift the production and transformation cost greatly.
