The reinforcing aid comprises 0.5-0.8 pt. wt. graphene oxide, glycidyl methacrylate, maleic anhydride, polypropylene, styrene, dicumyl peroxide, ethyl acetate, ethanol, PTFE powder, and steel fiber. USE - Flame retardant anti-aging wood plastic material for computer desk. ADVANTAGE - The wood-plastic material has improved flame retardance, tensile strength and bending strength. DETAILED DESCRIPTION - A wood plastic material comprises 25-30 pts. wt. polypropylene, 4-6 pts. wt. styrene-acrylonitrile copolymer, 1-1.5 pts. wt. glycidyl methacrylate, 0.2-0.4 pt. wt. dicumyl peroxide, 3-4 pts. wt. hexabromocyclododecane, 3-4 pts. wt. maleic anhydride grafted polyethylene, 1-1.5 pts. wt. phenyl salicylate, 30-35 pts. wt. wood flour, 5-7 pts. wt. water, and 6-9 pts. wt. reinforcing aid. The reinforcing aid comprises 0.5-0.8 pt. wt. graphene oxide, 0.8-1.2 pts. wt. glycidyl methacrylate, 0.7-0.9 pt. wt. maleic anhydride, 6-8 pts. wt. polypropylene, 0.6-0.9 pt. wt. styrene, 0.03-0.06 pt. wt. dicumyl peroxide, 1-2 pts. wt. ethyl acetate, 1-2 pts. wt. ethanol, 0.5-0.8 pt. wt. PTFE powder, and 0.6-0.9 pt. wt. steel fiber. The reinforcing aid is prepared by mixing ethyl acetate and ethanol, adding glycidyl methacrylate, maleic anhydride and styrene, stirring for 10-15 minutes, adding graphene oxide, PTFE powder and steel fiber, stirring, adding dicumyl peroxide, heating at 70-80 degrees C, stirring for 10-20 minutes, adding remaining components, stirring for 20-30 minutes, heating at 120-130 degrees C, stirring for 20-30 minutes, feeding into parallel twin screw extruder, and extruding and granulating at 180-190 degrees C and at 200-250 rpm speed. An INDEPENDENT CLAIM is included for preparation of wood-plastic material, which involves (1) adding glycidyl methacrylate and dicumyl peroxide to water, heating at 90-95 degrees C, reacting for 20-30 minutes to obtain slurry, pouring wood flour into slurry while agitating the wood flour, drying to obtain modified wood flour, (2) mixing modified wood flour, hexabromocyclododecane and maleic anhydride grafted polyethylene, mixing at 80-90 degrees C and at 200-250 rpm for 7-9 minutes, feeding into parallel twin screw extruder, extruding and granulating at 150-160 degrees C and at 200-250 rpm speed to obtain particles, (3) mixing polypropylene and styrene-acrylonitrile copolymer at 80-90 degrees C and at 200-250 rpm for 6-8 minutes, feeding into parallel twin screw extruder, extruding and granulating at 170-190?OC and at 250-280 rpm speed to obtain particles, (4) mixing the particles in steps (2) and (3) with remaining components, adding into conical twin-screw extruder, adjusting speed at 30-40 rpm, and extruding at 140-160 degrees C.
