Wear-resistant boron nitride ceramic grinding wheel and preparation method of same
The invention discloses a wear-resistant boron nitride ceramic grinding wheel and a preparation method of the same. The grinding wheel is prepared from following raw materials, by weight, 90-120 parts of boron nitride, 1-5 parts of aluminum oxide, 2-7 parts of kaolin, 0.8-2 parts of zirconium oxide, 1.5-4 parts of calcium oxide, 2-6 parts of titanium dioxide, 1.8-3.5 parts of antimonous oxide, 0.6-3 parts of carbon fiber, 0.05-0.3 parts of a surfactant, 0.5-3 parts of polyethylene, 25-30 parts of anhydrous ethanol, 2-5 parts of glycerin and 65-75 parts of deionized water. The boron nitride ceramic is improved in fracture toughness, strength, compactness and wear resistance. The preparation method is simple in operations, is wide in raw material sources and can enlarge the use range of the boron nitride ceramic.
