▎ 摘　　要

NOVELTY - Radiation protection film material comprises 23-28 pts. wt. polycarbonate, 15-19 pts. wt. modified kaolin, 8-14 pts. wt. barite powder, 7-11 pts. wt. cellulose, 8-12 pts. wt. titanium dioxide, 7-13 pts. wt. mica powder, 6-10 pts. wt. zinc ore, 5-10 pts. wt. calcium carbonate, 9-14 pts. wt. graphene, 7-12 pts. wt. compound emulsion, 8-12 pts. wt. polypropylene glycol, 4-7 pts. wt. film forming agent, 3-6 pts. wt. additives, 4-7 pts. wt. thickener and 6-10 pts. wt. deionized water. USE - Radiation protection film material for a computer. ADVANTAGE - The radiation protection film material has waterproof, high permeability and good radiating effect, not only is the normal operation of computer provides assurance, also provides safety guarantee for the computer user, and effectively reduces the damage caused by radiation and has better use value. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a radiation protection film material, which involves: (A) mixing modified kaolin, titanium dioxide, mica powder, zinc ore and calcium carbonate, and crushing into a mill to a sieve of 500 mesh, adding to deionized water, and heating to 46-48 degrees C, ultrasonic dispersion for 15-18 minutes to obtain a mixture; (B) introducing the polycarbonate into the reaction vessel for heating, heated to 80-82 degrees C, heating to complete melting, and then graphene and polypropylene diol are add, the temperature is lowere to 50-53 degrees C, and the reaction is slowly stirring for 20-25 minutes to obtain a mixture of two; (C) introducing tha mixture 1, mixture 2, barite powder and cellulose into a high-speed shearing machine, shear and disperse for 8-12 minutes at a speed of 450-500 revolution per minute (rpm), than add additives and thickener, stir into a viscous shape to get obtain a mixture of three; and (D) mixing the mixture III, the composite emulsion and the film-forming auxiliary agent into a twin-screw extruder, melt-extruding, and then introducing into a molding machine to form a finished product.
