Abstract

The invention relates to the field of auto parts preparation, in particular to a method for preparing an automobile brake pad. According to parts by weight, the material consists of 15-20 parts of neoprene rubber, 0.5-1 part of epoxy resin, and 0.5-1 part of nano-bismuth powder. 1 part, 0.2-0.5 part of talc powder, 0.2-0.5 part of magnesium oxide powder, 0.2-0.5 part of calcium silicate powder, 0.2-0.5 part of curing agent, mix the above components and heat to 250-280 degrees Celsius and keep 1- 2h, pour into the sand mold again, form the primary product of automobile brake pad after cooling, take out the primary product of automobile brake pad and electroplate a layer of wear-resistant metal material on the surface of the primary product. The invention adopts novel materials, which contain nanometer materials, and nanometer pens are mixed into epoxy resin, together with other components and a wear-resistant metal material layer, so that the automobile brake pad has high hardness and superior wear resistance.

Description

technical field [0001] The invention relates to the field of auto parts preparation, in particular to a method for preparing an auto brake pad. Background technique [0002] Automobile brake pads are parts that are frequently used and easily worn during the use of automobiles.
