Abstract

The present application relates to a polypropylene composite material and its preparation method and application. The polypropylene composite material, in parts by weight, includes the following components: 50 to 80 parts of polypropylene resin, 5 to 20 parts of silicon dioxide modified with Lewis acid and nickel salt, and 5 to 20 parts of nitrogen flame retardant. By using silicon dioxide modified with Lewis acid and nickel salt in combination with polypropylene resin and nitrogen flame retardant, the obtained polypropylene composite material can take into account both high flame retardant efficiency and good noise reduction effect, and is suitable for the fields of automobiles, electronic products, furniture or building materials.
