Abstract

The invention discloses a magnetic composite material and a preparation method thereof. The composite material is prepared by mixing and firing a material A and a material B. The weight ratio of the material A to the material B is 100: 3 to 6. The material A comprises, by weight, 1 to 3% of B, 25 to 28% of Nd, 1.8 to 2.2% of Ni, 0.008 to 0.013% of Ag, 0.08 to 0.12% of Ta, 2 to 5% of Tm, 0.1 to 0.5% of Be, 1.5 to 1.9% of Si and the balance of Fe. The material B consists of a substance (Na, Ca) 0.33 (Al, Mg) 2 [Si4O10] (OH) 2.nH2O, a substance Na2O.Al2O3.6SiO2 and ferric tetroxide, wherein the weight ratio between the three is 1: 0.2 to 0.6: 5. The magnetic composite material provided by the invention has high comprehensive magnetic properties. In addition, the materials are properly treatedduring preparation to ensure the uniformity of material composition, structure and properties, and to ensure the alloy quality. The material preparation process is simple. The cost of raw materials used for preparation is low. The process is simple. The produced material has good properties, is convenient for industrial production, and has a good application prospect in electric appliance industry.
