The invention discloses a flame retardant high-heat-resistant polypropylene composite material for a transparent electric cooker and a preparing method and application of the flame retardant high-heat-resistant polypropylene composite material. The composite material is composed of, by mass, 60-97% of high-crystallized homo-polypropylene, 1-20% of transparent padding master batch, 1.7-10% pf flame retardant master batch, 0.1-5% of scraping-resistant master batch, 0.1-2% of thermal oxidative aging resisting agent and 0.2-3% of addition agent. All the components are evenly mixed and added in a parallel double-screw extruding machine, blending and melt extrusion are carried out, and the composite material is obtained. The composite material is low in cost and excellent in comprehensive physical and mechanical property and can be used in the fields of small household appliances such as electric cookers, pressure cookers, induction cookers and soybean milk machines.
