Embodiment 1

[0025] Utilize self-made asphalt-based COPNA resin. This resin is to use the coal tar pitch produced by the coking plant of Taiyuan Coal Gasification Co. The raw materials are put into the reactor together. During the whole reaction process, it is under normal pressure and protected by nitrogen gas to prevent oxidation. The nitrogen gas flow rate is 50mg / min. , in a stirring state, rise to 160 ° C, react for 6 hours and then leave the kettle. The phenolic resin used in the examples is an epoxy-modified phenolic resin produced by Zibo Hengtai Resin Factory. The adhesive properties of this resin are extremely strong.

[0026] Weighing: 40 grams of 6mm long and short-cut general-grade pitch carbon fiber, 40 grams of COPNA resin, 80 grams of phenolic resin passed through a 200-mesh sieve, 200 grams of steel fiber, 5 grams of 6mm long viscose fiber, 35 grams of aluminum silicate fiber, and 150 grams of graphite powder , 100 grams of petroleum coke powder, 50 grams of aluminum po...

Embodiment 2

[0028] Weigh 70 grams of COPNA resin, 60 grams of phenolic resin, 80 grams of carbon fiber, 150 grams of steel fiber, 10 grams of aramid fiber, 20 grams of oxidized fiber, 50 grams of wollastonite fiber, 70 grams of chromite powder, barium sulfate powder 100 grams, iron powder 80g, brass paste 100g, graphite powder 100g, petroleum coke powder 60g, cashew nut shell powder 40 grams, nitrile rubber powder 10 grams, preparation method is with embodiment 1.

Embodiment 3

[0030] Weigh 100 grams of COPNA resin, 40 grams of phenolic resin, 250 grams of steel fiber, 30 grams of aramid fiber, 10 grams of viscose silk, 150 grams of sepiolite fiber, 50 grams of aluminum silicate fiber, 150 grams of graphite powder, aluminum powder 50 grams, 60 grams of flavonoid crumbs, 20 grams of silicon powder, 50 grams of calcium carbonate powder, 40 grams of cashew nut shell powder, the preparation method is the same as in Example 1.

Abstract

The percentage of each component weight for a vehicle disk brake gasket is: carbon fiber 0-16; steel fiber 5-25; organic fiber 0.5-8, mineral fiber 3-20; friction performance adjuster 37-60; COPNA resin 4-16; phenolic resin 0-8. Its preparation applies a dry technology to weigh, mix and stir matters in certain proportion then to be dried and moulded by chill-pressure, heat-pressure and after heatprocess mechanical process, polish, spraying paint, and packaging to become product with the advantage of no noise, no vibration, no scuffing the opposite side when braking.

Description

Technical field: [0001] The invention belongs to friction materials, in particular to a car disc brake lining. Background technique: [0002] Brake lining is one of the key materials in the automobile industry. Its quality not only affects the driving performance but also affects the life safety of drivers and passengers. Therefore, it is required that the brake lining material used must have good thermal fading resistance, stable friction coefficient at high temperature, no noise in the braking process, sufficient strength to match well with the counterpart, and not damage the counterpart surface. Moderate coefficient of friction and small wear and other properties. Since the invention of automobiles, in order to pursue the above-mentioned performances, the research on brake materials has not stopped, and the brake materials of the previous generation have been replaced by safer, more comfortable and better performance brake materials. [0003] Traditional automobile brak...
