Zusammenfassung:	The present invention discloses a calcium carbonate whisker reinforced rubber base friction material, and a preparation method therefor. The material comprises: 8-15 parts of nitrile rubber, 10-15 parts of styrene-butadiene rubber, 5-10 parts of phenolic resin, 5-25 parts of calcium carbonate whisker, 10-20 parts of steel fiber, 2-8 parts of sepiolite fiber, 0-8 parts of mineral fiber, 0-3 parts of aramid fiber, 5-8 parts of barium sulfate, 5-10 parts of magnesium oxide, 2-3 parts of aluminum oxide, 5-10 parts of flake graphite, 1-5 parts of carbon black, 5-10 parts of petroleum coke, 3-6 parts of Cardolite cashew nut shell oil friction powder, 0.5-1 parts of sulfur, and 0.5-1 parts of accelerator. The preparation method comprises process steps of such as material collocation, mixing, pressing molding and the like. Brake pads synthesized by the method provided by the invention have the advantages including excellent friction and wear performance, stable braking performance, high heat-resistant property, safe, environmentally-friendly, and low in cost; and is suitable for braking devices for automobiles and motive power machines, thereby achieving a very wide application prospect and applying to industrial production.
