Abstract

The invention discloses an environmental friendly energy-saving vehicle brake block and relative producing method, which is characterized in that: it is prepared by following components and weight percentages: iron: lead: graphite: silicon dioxide: phosphor: sulfur flour: zinc stearate: lubricant= 77-85:2-3:9-15:1-3í†0.7 -1í†0.3-0.8í†0.6-0.8í†0.01-0.03. The producing method comprises: breaking the casting slag into 60-100 deals into container to be fed into electric furnace to be heated, and reduced into 97-98.5% iron content; adding lead powder, graphite powder, phosphor powder, sulfur flour powder, zinc stearate and lubricant, to be uniformly mixed and fed into vehicle brake block mould to be compressed and molded in 4-5T / cm2; getting out and putting it into the container to be sintered in high-temperature electric furnace for 2 hours; cooling and drilling the screw hole. The invention can save material, reduce the cost, improve the abrasion resistance property and reduce the abrasion of couple element.

Description

technical field [0001] The invention relates to the technical field of brakes, in particular to an environment-friendly and energy-saving automobile brake pad and a production method thereof. Background technique [0002] As we all know, brake pads are an essential safety accessory for cars. The original asbestos resin brake pads have seriously polluted the environment and endangered human health, and most countries have banned their use. The original powder metallurgy brake pads, such as the 2811 brake pads imported from the former Soviet Union, have a raw material formula of 69% iron, 4% molybdenum, and 5% copper. %, lead 10%, graphite 11%, silicon dioxide 1%. The brake pads of this kind of ingredients have the following defects: first, some properties do not match with the dual material brake drum or brake disc, resulting in large wear of the dual material, and secondly, it needs to use expensive molybdenum and a large amount of copper, which is not conducive to resource...
