Description
Technical Field
The invention belongs to the technical field of brake pad manufacturing, and particularly relates to a novel metal-free composite material automobile brake pad.
Background
The brake pad belongs to the most critical safety brake part in the braking system of car, and the brake effect is that the brake pad plays the decisive role, and the brake pad generally comprises steel sheet, bonding insulating layer and clutch blocks, and wherein the insulating layer comprises the material that does not conduct heat, the purpose is thermal-insulated. The friction block is composed of friction material and adhesive, and is extruded on a brake disc or a brake drum to generate friction when braking, so that the aim of decelerating and braking the vehicle is fulfilled. The pads are gradually worn away due to friction, generally speaking, the lower the cost the faster the brake pad will wear. After the friction material is used up, the brake pad needs to be replaced in time, otherwise, the steel plate can be in direct contact with the brake disc, the brake effect is finally lost, and the brake disc is damaged, so that the unexpected result is caused.
In the existing friction material market, brake pads are divided into asbestos brake pads and semi-metal brake pads. Because asbestos in the asbestos brake block has carcinogenic harm, the brake block of the type is gradually eliminated by the market again; the semimetal brake pad contains metal substances, so that the semimetal brake pad is easy to damage couples during braking, has great braking damage and has short service life.
Therefore, a novel brake pad is developed, the performance of the brake pad is improved, and the stability of an automobile brake system is improved.
Disclosure of Invention
The invention aims to provide a novel metal-free composite material automobile brake pad, aiming at solving the problems that the existing asbestos brake pad and semimetal brake pad are eliminated or unstable in performance and are easy to generate potential braking harm during braking.
The invention relates to a novel metal-free composite material automobile brake pad, which is composed of the following raw materials in parts by weight:
ceramic fiber 10-20 wollastonite fiber 5-10
Mineral fiber 10-20 basalt fiber 5-10
Phenolic resin 20-30 nitrile rubber 10-20
Silicon gray cotton 1-3 barium sulfate whisker 5-10
5-10 parts of alumina and 5-10 parts of calcium carbonate;
during preparation, phenolic resin, nitrile rubber, ceramic fiber, wollastonite fiber, mineral fiber and basalt fiber are added into a mixer for mixing, and then silicon gray cotton, barium sulfate whisker, aluminum oxide and calcium carbonate are sequentially added into the mixer for mixing; and after the material mixing is finished, placing the mixed material in a brake pad mold, carrying out hot press molding at the temperature of 140-.
The invention discloses a novel metal-free composite material automobile brake pad, which is preferably prepared from the following raw materials in parts by weight:
ceramic fiber 15 wollastonite fiber 8
Mineral fiber 15 basalt fiber 8
Phenolic resin 25 nitrile rubber 15
Silicon gray cotton 2 barium sulfate whisker 8
Alumina 7 calcium carbonate 7.
The brake pad adopts ceramic fiber, wollastonite fiber, mineral fiber and basalt fiber to replace the traditional asbestos, adopts phenolic resin and nitrile rubber as bonding agents, and adopts wollastonite cotton, barium sulfate whisker, aluminum oxide and calcium carbonate to enhance various performances of the brake pad, especially high temperature resistance. The automobile brake pad prepared by the invention has high friction temperature resistance, low wear rate and long service life, and avoids the problem of brake failure caused by overhigh temperature.
