Powder metallurgy friction material for high-speed train brake pad and preparation method of powder metallurgy friction material

The invention relates to the field of rail transit, in particular to a powder metallurgy friction material for a brake pad of a high-speed train and a preparation method of the powder metallurgy friction material, and the friction material is prepared from the following components in parts by weight: electrolytic copper powder, iron powder, tin powder, manganese powder, nickel powder, mullite, molybdenum disulfide, silicon carbide, tungsten carbide, artificial graphite, titanium oxide and aluminosilicate ore powder. The preparation method comprises the steps of material weighing, material mixing, compression molding, sintering molding and the like. According to the powder metallurgy friction material for the high-speed train brake pad and the preparation method of the powder metallurgy friction material, the prepared brake pad has good physical and mechanical properties and stable friction and wear properties, and the heat fading capacity of the brake pad is obviously enhanced. 本发明涉及轨道交通领域，特别涉及一种高速列车制动闸片用粉末冶金
