Formula for preparing brake pads by utilizing acicular ceramic fiber

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. ...
