Problems solved by technology

The friction temperature of this type of brake pad is relatively high, and its braking principle is to use ceramic fibers or metal fibers to generate shear friction with the braking dual material to achieve the purpose of braking. When braking, the frictional dual material is deeply damaged, and it is easy to produce brake furrows. , affecting the service life of the dual material, the longer the time, the worse the braking performance
At the same time, the noise of such brake pads is relatively large, and the environmental pollution is also relatively serious.
[0003] Moreover, when the above-mentioned brake pads for vehicles currently used are used as winch wheel hub brake pads of workover machines, drilling machines, drilling machines, etc. used in oil fields, the use effect is not good, and carcinogens, sparks, etc. will be produced during use. , endangering the personal safety of the operator

Abstract

The invention relates to an environment-friendly bamboo charcoal composite ceramic brake which comprises the following raw materials in percentage by weight: 3-40 percent of floating bead, 3-35 percent of meerschaum, 4-30 percent of mica, 3-50 percent of plant fiber, 5-40 percent of barite, 2-30 percent of light weight calcium, 4-30 percent of molybdenum disulfide, 2-25 percent of titanium pigment, 1-10 percent of flame retardant, 2-25 percent of barium sulfate, 10-28 percent of 213 resin, 3-26 percent of methenamine, 5-30 percent of kaolin and 5-33 percent of figuline; the percentage sum by weight of the raw materials is 100 percent. The environment-friendly bamboo charcoal composite ceramic brake has the characteristics of good braking performance, long service life, low noise, little environment pollution and the like.

Description

technical field [0001] The invention relates to an environment-friendly bamboo-charcoal composite ceramic brake pad, and also relates to a preparation method of the above-mentioned environment-friendly bamboo-charcoal composite ceramic brake pad. Background technique [0002] At present, among the brake pads for braking and transmission, the brake pads of composite materials containing ceramics and fibers are mostly used, which are characterized by having ceramic properties and containing metal fibers. The friction temperature of this type of brake pad is relatively high, and its braking principle is to use ceramic fibers or metal fibers to generate shear friction with the braking dual material to achieve the purpose of braking. When braking, the frictional dual material is deeply damaged, and it is easy to produce brake furrows. , affecting the service life of the dual material, the longer the time is, the worse the braking performance will be. Simultaneously, the noise of...
