Abstract
The invention relates to a method for preparing friction materials, in particular to a method for preparing a brake pad of a car by utilizing liquid nitrile rubber. The brake pad is prepared from the liquid nitrile rubber, a resin, fiber, a friction increasing agent, an antifriction agent and a friction regulator according to process steps of burdening, material mixing, cold molding, vulcanization, grinding and inspection. The brake pad comprises the following raw materials in part by weight during the burdening: 2 to 5 parts of liquid nitrile rubber, 5 to 15 parts of resin, 2 to 10 parts of aramid short fiber, 10 to 20 parts of ceramic fiber, 5 to 15 parts of copper fiber, 4 to 6 parts of zircon, 1 to 3 parts of iron oxide black, 1 to 10 parts of graphite, 3 to 10 parts of friction-type mix, 20 to 30 parts of barium sulfate, 15 to 25 parts of potassium titanate, and 2 to 4 parts of tire powder. Through the detection of TP2044 standard of an American LINK3900 bench, the performance of the brake pad prepared by the method meets the requirement, and the brake pad has low braking noise. The method does not need to improve a conventional process, which saves production and retrofitting cost.
Description
One, technical field: the present invention relates to method for preparing friction, especially utilize liquid nitrile rubber to prepare the method for brake pad of car.
Two, background technique: generally include following component in the brake block preparation process: resin, rubber powder, increase grinding agent, anti-friction composition, friction modifier, bulking agent at fiber.Its processing technology mainly comprises batching-batch mixing-cold mould-sulfuration-grinding-check-packing.For the car disc, noise free that frictional behaviour is good or low noise brake block become first-selection.Rubber is the principal element that influences the brake block noise, though conventional formulation is also added rubber powder, noise problem still exists greatly.
Three, summary of the invention: purpose of the present invention is exactly at the existing defective of existing brake pad of car, and the LNBR that utilizes that provides a kind of noise free or low noise obviously to improve prepares the method for brake pad of car.To achieve these goals, the present invention furthers investigate and comparative trial around the following aspects emphatically: the one, and the selection of high-temperature resistant rubber 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.Following technological scheme is proposed on this basis: utilize liquid rubber to prepare the method for brake pad of car, be with liquid nitrile rubber, resin, fiber, increase grinding agent, anti-friction composition, friction modifier and bulking agent make by following process step, batching-batch mixing-cold mould-sulfuration-grinding-check, anti-friction composition wherein is that graphite rubs, wiping modifier is the friction powder, described material, liquid nitrile rubber, resin, fiber adopts aramid fiber short fibre and ceramic fiber, the copper fiber is mixed, and increases grinding agent and adopts zircon and iron oxide black to be mixed, bulking agent adopts barium sulphate and potassium titanate, tyre talc is mixed, various raw-material weight portions are respectively in the blending process, liquid nitrile rubber 2-5, resin 5-15, aramid fiber short fibre 2-10, ceramic fiber 10-20, copper fiber 5-15, zircon 4-6, 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, liquid nitrile rubber 3, resin 8, aramid fiber short fibre 3, ceramic fiber 15, copper fiber 10, zircon 5, iron oxide black 2, graphite 8, friction powder 4, barium sulphate 25, potassium titanate 17, tyre talc 3.Adopt the brake block of technological method preparation of the present invention, detect through U.S. LINK3900 stand, various performances meet the requirements, and noise measuring is qualified.This technology does not need existing processing technology is improved in addition, has saved the production and transformation cost greatly.
