Abstract

The invention belongs to the technical field of locomotive brake shoes and particularly relates to a friction material and a locomotive brake shoe produced from the same. According to the friction material for producing the locomotive brake shoe, phenolic resin, steel-cotton fibers, glass fibers, mineral fibers, high-density polyethylene, low-density polyethylene, medical stone, bentonite, cement,cellulose ether, silicon spar powder and coal ash floating beads serve as raw materials. Performance of the locomotive brake shoe produced from the friction material can meet requirements of locomotive brake shoe; in addition, the obtained brake shoe is high in high-temperature friction coefficient; the friction performance is stable at the high temperature; and the friction material is suitablefor meeting requirements of the locomotive brake shoe.

Description

technical field [0001] The invention belongs to the technical field of brake shoes for locomotives, and in particular relates to a friction material and a brake shoe for locomotives prepared therefrom. Background technique [0002] The locomotive adopts microcomputer network control, standardized and modular design, and has the advantages of wide constant power range, large shaft power, good adhesion characteristics, high power factor, small harmonic interference, low maintenance rate and full-life operating cost, and wide application range. , is one of the important symbol products of China's railway equipment technology modernization. It is generally driven by steam engines, diesel engines, gas turbines, traction motors and other power machinery directly or through transmission devices, and achieves the braking effect of locomotives through braking devices. [0003] With the rapid development of our country's economy and the rapid increase of railway passenger and cargo t...
