[0018] According to above formula according to the production technology processing sample of prior art is tested, the result is:
[0019] FAW-Volkswagen BORA's original supporting brake pads are metal-less friction pads produced by Germany's TMD company. During use, the braking distance at a speed of 100 kilometers is 52.6 meters. The TP2044 bench test shows that the friction coefficient is the highest at a speed of 160 km / h. 0.26, and the brake friction coefficient is around 0.30 at 500°C.
[0020] After using the processed brake pad of the formula A of the present invention, the braking distance at a speed of 100 kilometers is 43.8 meters. In the TP2044 bench test, the lowest point of the friction coefficient is 0.29 at a speed of 160Km / h, and the friction coefficient is 0.35 at 500°C.
[0021] The original brake pads for FAW-Volkswagen A6 are metal-less friction pads produced by TMD Company in Germany. During use, the braking ...

Abstract
The invention provides a preparing formula of brake pad by utilizing acicular ceramic fiber. Ingredients of the formula comprise (by weight) 5%-10% of adhesive, 15%-20% of reinforced fiber, 20%-30% of abrasive, 15%-25% of lubricant, 10%-15% of modifier and 20%-30% of filler, wherein the adhesive is phenolic resin, or silicon modified phenolic resin, or butyronitrile modified phenolic resin or mixture of the three, the reinforced fiber is acicular ceramic fiber, or aramid pulp, or copper fiber or mixture of the three, the abrasive is zirconium silicate, or iron black, or aluminium oxide or mixture of the three, the lubricant is graphite, or metal sulfide or mixture of the both, the modifier is friction powder, or potassium titanate wafer or mixture of the both, and the filler is barium sulfate, or calcium carbonate or mixture of the both. By the aid of the preparing formula of brake pad by utilizing acicular ceramic fiber, the heat energy generated from rapid brake can be effectively absorbed by the finished brake pad in usage, and the thermal conductivity of the brake pads can be reduced, so that the brake pads have excellent braking performances in terms of high-temperature resistance, rapidness and comfortability.
Description
technical field [0001] The invention relates to a production formula of a brake pad, in particular to a formula for producing a brake pad by using needle-like ceramic fibers. Background technique [0002] The main formulations of the existing brake pads are binders, reinforcing fibers, abrasives, lubricants and necessary regulators. [0003] The processing technology is as follows: mixing materials, hot pressing, heat treatment, grinding, painting, installing accessories, printing labels, packaging. [0004] With the rapid development of the modern automobile industry, the speed of passenger cars is getting higher and higher. This also requires that the brake pads not only have good braking effect, but also have good heat resistance and good braking comfort. At present, the common problem of brake pads is that the thermal conductivity of the product is high, so the braking performance and braking comfort under high temperature and high speed conditions are not very ideal. ...
