Problems solved by technology

At present, the disc brake pads of automobiles are mainly semi-metallic brake pads. The main advantage of this brake pad is that it can adapt to normal work at higher temperatures, but there is a problem of excessive heat conduction in the working process, so under high temperature and high speed conditions The timeliness and wear resistance of braking performance are relatively poor
At the same time, there are often problems of large vibration and high braking noise during the braking process.

Embodiment 1

[0013] A disc brake pad is prepared from the following components according to the corresponding proportions: cashew nut shell oil modified phenolic resin 5-9%, steel fiber 5-9%, brass fiber 2-4%, composite mineral fiber 4% ~8%, foam iron powder 15~25%, fiber foam stone 4~8%, vermiculite 3~7%, wollastonite 6~10%, barite 2~6%, antimony sulfide 0.5~2%, Ceramic fiber 3-7%, graphite 6-10%, mica 3-7%, friction powder 2-4%, rubber powder 2-4%, ceramic grinding agent 4-8%, aramid fiber 0.5-2%, Zinc powder 1-3%.

[0014] Its production process includes the following process steps:

[0015] 1. Prepare the steel back: first clean the steel back until the surface stains are cleaned, then use a shot blasting machine to blast the steel back until the surface steel back reaches the specified roughness, and finally spray the steel back with glue ;

[0016] 2. Ingredients: weigh the above formula according to the proportion requirements, and send the ingredients into the mixer to mix the i...

Abstract

The invention relates to a disc brake pad, and belongs to the technical field of automobile brake pad manufacturing. The disc brake pad is prepared by following components including, by ratio, 5%-9% of cashew nut shell oil modified phenolic resin, 5%-9% of steel fiber, 2%-4% of brass fiber, 4%-8% of composite mineral fiber, 15%-25% of foam iron powder, 4%-8% of fiber foam stone, 3%-7% of vermiculite, 6%-10% of wollastonite, 2%-6% of barite, 0.5%-2% of antimony sulfide, 3%-7% of ceramic fiber, 6%-10% of graphite, 3%-7% of mica, 2%-4% of frictional powder, 2%-4% of rubber powder, 4%-8% of a ceramic friction increasing agent, 0.5%-2% of aramid fiber and 1%-3% of zinc powder. The obtained brake pad has the beneficial effects that the friction coefficient at the high temperature is stable, abrasion resistance is good, the braking noise is low, vibration is small, the preparing method is simple, the service life is long, and cost is low.

Description

technical field [0001] The invention relates to a disc brake pad, which belongs to the technical field of automobile brake pad manufacturing. Background technique [0002] With the development of the automobile industry, the speed of automobiles is constantly increasing, which puts forward higher requirements for the braking performance of automobiles, and the key components that affect the braking performance of automobiles are brake pads, so a kind of friction performance is developed. High-quality brake pads have positive and practical significance for improving the braking performance of the car. At present, the disc brake pads of automobiles are mainly semi-metallic brake pads. The main advantage of this brake pad is that it can adapt to normal work at higher temperatures, but there is a problem of excessive heat conduction in the working process, so under high temperature and high speed conditions The timeliness and wear resistance of the braking performance are relat...
