Description

[0001] technical field [0002] The invention relates to the modification of a polymer composite material and a preparation method thereof, in particular to a polypropylene composite material and a preparation method thereof. Background technique [0003] With the development of the automobile industry and household appliances, the demand and functional requirements for polypropylene materials are increasing. At present, the modification of polypropylene materials mainly uses heat conduction agents such as silicon carbide, alumina and magnesium oxide. . During the synthesis process of silicon carbide, it is difficult to completely remove graphite, resulting in low product purity and a decrease in the mechanical strength of the material after modification, while the thermal conductivity of magnesium oxide and alumina fillings has disadvantages such as poor corrosion resistance and low addition amount. The present invention innovatively selects the feldspar powder commonly us...
