NOVELTY - A radiation-proof computer screen protection film comprises 10-25 pts. wt. xanthan gum, 15-35 pts. wt. carrageenan, 2-5 pts. wt. nano titanium dioxide, 3-9 pts. wt. nano zinc oxide, 2-10 pts. wt. rose essential oil, 1.5-3.5 pts. wt. yttrium nitrate, 3-10 pts. wt. graphene dispersion liquid, 1-4 pts. wt. polyimide resin,1-3 pts. wt. diamine monomer, and 0.5-3.5 pts. wt. plasticizer. USE - Radiation-proof computer screen protection film. ADVANTAGE - The radiation-proof computer screen protection film has simple preparation method, low cost, and good film forming effect, prevents computer screen of blue light penetration, and reduces radiation harm to people on a certain extent. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of protection film comprising taking xanthan and carrageenan, adding into distilled water, stirring, and dissolving at 60-80 degrees C; adding nano titanium dioxide and nano zinc oxide, mixing, adding water, heating, and stirring at 80-90 revolutions/minute for 1-2 hours; adding rose essential oil, yttrium nitrate, and graphene dispersion liquid, dissolving, adding polyimide resin and diamine monomer, stir-reacting at 40-60 degrees C for 1-2 hours; and adding plasticizer, stirring, mold, and drying at 50-70 degrees C.
