Abstract
The invention relates to vehicle accessories, namely an automobile clutch disc and a brake block of low temperature carbonized and pre-oxidized wires and a production technique thereof. The friction material of the accessories is made from raw materials by weight percent as follows: 5 to 10 percent of low temperature carbonized and pre-oxidized wire, 15 to 18 percent of phenolic resin, 6 to 11 percent of rutile, 9 to 11 percent of chromite powder, 5 to 10 percent of manganese steel wool, 5 to 10 percent of aluminium oxide, 6 to 11 percent of red copper powder, 6 to 11 percent of wollastonite powder, 5 to 6 percent of feldspar powder, 6 to 11 percent of titanium dioxide, 8 to 13 percent of barium sulfate, 3 to 5 percent of quartz sand, 1 to 3 percent of graphite powder and 6 to 8 percent of graphite electrode powder. The production technology comprises steps of section-cutting of low temperature carbonized and pre-oxidized wire, material-mixing, ethanol-spraying, particle-producing, cold-model manufacturing, hot forming, hot processing and putting in a storage. The accessories have low cost and better mechanical property, friction performance and braking performance.
Description
technical field [0001] The invention relates to a motor vehicle accessory, that is, a low-temperature carbonized pre-oxidized wire automobile clutch disc and brake disc and a production process thereof Background technique [0002] In the prior art, automotive clutch or brake pads consist of a steel backing plate and friction material thereon. The friction material is composed of reinforcing agent, basic resin and regulator. The reinforcing agent of the friction material is gradually replaced by carbon fiber from the traditional asbestos material. The disadvantage is that the price of carbon fiber is expensive, resulting in high cost of finished parts. Usually carbon fiber is 800 yuan / kg, while low-temperature carbonized pre-oxidized wire is 260 yuan / kg. Carbon fiber is a high-tech material in the aerospace field. It is really wasteful and overkill to use it in friction materials. There are many kinds of modifiers (modifiers), some of which use kaolin, talcum powder, and g...
