The invention discloses the application of an injection molding wood plastic composite in producing electric appliance housing. The injection molding wood plastic composite is composed of the following components in part by weight: 100 parts of thermoplastic resin; 1-400 parts of plant powder; 0.1-40 parts of dispersing agent; 0.5-60 parts of impact modifier; 0-100 parts of inorganic filler; and 0-10 parts of antioxidant. It is found through long-term research that the injection molding wood plastic composite is extremely great for producing various electric appliance housings, hence, for thefirst time the injection molding wood plastic composite is brought into the production field of electric appliance housing, giving rise to tremendous revolutionary transform of the material for producing electric appliance housing. The injection molding wood plastic composite according to the invention, preferably the plant powder-modified thermoplastic wood plastic composite material, has the characteristics of good durability and dimensional stability, great easiness for molding, small water absorbability and excellent corrosion resistance compared with woods, and has the characteristics oflow cost and high rigidness compared with plastics.
