NOVELTY - Preparing graphene-doped fluorine-containing silicon acrylate polymer packaging material comprises e.g. (i) adding nonylphenol ethoxylate into deionized water, adding methyl methacrylate, n-butyl acrylate, vinyl triethoxy silane, 3-glycidoxypropyltrimethoxysilane and methyltrifluoropropylcyclotrisiloxane, and stirring, (ii) adding deionized water, buffer sodium bicarbonate and monomer pre-emulsion into a four-necked flask, heating, dispersing, adding remaining ammonium persulfate aqueous solution, heating, removing the emulsion, adjusting the pH with aqueous ammonia when the temperature is lowered to 40 degrees C, and filtering to obtain fluorine-containing silicone acrylate polymer emulsion, and (iii) mixing epoxy resin, fluorine-containing silicon acrylate polymer emulsion, graphene oxide, graphene fluoride, coupling agent, curing agent, and mechanically stirring, vacuum defoaming for 5-8 hours, adding into the mold for curing at 130-140 degrees C, and cooling to room temperature. USE - The method is useful for preparing graphene-doped fluorine-containing silicon acrylate polymer packaging material. ADVANTAGE - The prepared material has good weather resistance, anti-aging property, mechanical property and impact resistance. DETAILED DESCRIPTION - Preparing graphene-doped fluorine-containing silicon acrylate polymer packaging material comprises (i) adding nonylphenol ethoxylate into deionized water, adding methyl methacrylate, n-butyl acrylate, vinyl triethoxy silane, 3-glycidoxypropyltrimethoxysilane and methyltrifluoropropylcyclotrisiloxane, and magnetic stirring at 40 degrees C with a rotational speed of 800 rotations/minute for 20 minutes to obtain monomer pre-emulsion, (ii) adding deionized water, buffer sodium bicarbonate and 1/ three quarters monomer pre-emulsion into a four-necked flask, adding a small amount of completely dissolved ammonium persulfate aqueous solution, and heating to 80 degrees C under nitrogen protection, dispersing the remaining 2/ three quarters of the monomer pre-emulsion in a high shear dispersing emulsifier for 10-15 minutes, and controlling the rotation speed at 5000 rotations/minute, when the apparent blue light appeared in the four-necked flask and there is no reflux, dropping the remaining monomer pre-emulsion into the four-necked flask through a constant pressure dropping funnel, controlling the dropping time for 2 hours, adding the remaining ammonium persulfate aqueous solution, heating to 85 degrees C for 2 hours, removing the emulsion, adjusting the pH to 8 with aqueous ammonia when the temperature is lowered to 40 degrees C, and filtering to obtain fluorine-containing silicone acrylate polymer emulsion, and (iii) mixing epoxy resin, fluorine-containing silicon acrylate polymer emulsion, graphene oxide, graphene fluoride, coupling agent, curing agent, and mechanically stirring for 2-3 hours, vacuum defoaming for 5-8 hours, adding into the mold for curing at 130-140 degrees C, and cooling to room temperature.
