NOVELTY - Anti-deformation plastic comprises 35-55 pts. wt. high hardness acrylonitrile butadiene styrene composite material, 15-30 pts. wt. toughening filler, 10-20 pts. wt. amino resin, 3-5 pts. wt. tributyl citrate, 3-5 pts. wt. compatilizer and 20-30 pts. wt. silicon dioxide. The anti-deformation plastic is prepared by mixing high hardness acrylonitrile butadiene styrene composite material, toughening filler, amino resin and silicon dioxide in turn into the mixer, stirring at uniform speed of 130-150degrees Celsius for 30 min, adding compatilizer, cooling to 120-130degrees Celsius, stirring for 5 min, then adding tributyl citrate, raising the temperature to 150-160degrees Celsius. USE - The anti-deformation plastic used in a closed ring of aircraft engine, damping block, and buffer block, and in plastic industry. ADVANTAGE - The anti-deformation plastic has increased specific surface area, and forms good phase interface with ABS resin, so as to stabilize the composite, and the hardness of the composite material can be obviously reinforced by adding carbon fiber. DETAILED DESCRIPTION - Anti-deformation plastic comprises 35-55 pts. wt. high hardness acrylonitrile butadiene styrene composite material, 15-30 pts. wt. toughening filler, 10-20 pts. wt. amino resin, 3-5 pts. wt. tributyl citrate, 3-5 pts. wt. compatilizer and 20-30 pts. wt. silicon dioxide. The anti-deformation plastic is prepared by mixing high hardness acrylonitrile butadiene styrene composite material, toughening filler, amino resin and silicon dioxide in turn into the mixer, stirring at uniform speed of 130-150degrees Celsius for 30 min, adding compatilizer, cooling to 120-130degrees Celsius, stirring for 5 min, then adding tributyl citrate, raising the temperature to 150-160degrees Celsius, stirring for 5 min, preparing the mixed material, adding the mixed material into the double-screw extruder, controlling the first section temperature is 170-190degrees Celsius, the second section temperature is 190-210degrees Celsius, the third section temperature is 210-220degrees Celsius, the die temperature is 210-230degrees Celsius, extruding, granulating to obtain the anti-deformation plastic. An INDEPENDENT CLAIM is included for a method for preparing anti-deformation plastic, which involves adding high hardness acrylonitrile butadiene styrene composite material in turn into the mixer, stirring at uniform speed of 130-150degrees Celsius for 30 min, adding compatilizer, cooling to 120-130degrees Celsius, stirring for 5 min, then adding tributyl citrate, raising the temperature to 150-160degrees Celsius, stirring for 5 min, preparing the mixed material, adding the mixed material into the double-screw extruder, controlling the first section temperature is 170-190degrees Celsius, the second section temperature is 190-210degrees Celsius, the third section temperature is 210-220degrees Celsius, the die temperature is 210-230degrees Celsius, extruding, granulating to obtain the anti-deformation plastic.
