NOVELTY - Preparation of light-emitting composite paint involves dispersing graphene/kaolin/silica composite material and graphene/calcium carbonate/silica composite into deionized water and obtaining solution (A3), dispersing graphene/red-emit phosphor/silica composite into deionized water and obtaining solution (B3), dispersing graphene/long afterflow phosphor composite into deionized water and obtaining solution (C1) and slowly dripping solutions (B3) and (C1) in the solution (A3), then adding film-forming agent, mixing and stirring uniformly. USE - Preparation of light-emitting composite paint (claimed). ADVANTAGE - The method efficiently and economically provides light-emitting composite paint with high luminous intensity and luminous uniformity and excellent storage stability. DETAILED DESCRIPTION - Preparation of light-emitting composite paint involves dispersing 3-6 pts. wt. graphene/kaolin/silica composite material and 2-4 pts. wt. graphene/calcium carbonate/silica composite into 15-20 pts. wt. deionized water, processing for 90-120 minutes and obtaining solution (A3), dispersing 1-5 pts. wt. graphene/red-emit phosphor/silica composite into 15-20 deionized water, processing for 90-120 minutes and obtaining solution (B3), dispersing 1-5 pts. wt. graphene/long afterflow phosphor composite into 15-20 pts. wt. deionized water, processing for 90-120 minutes and obtaining solution (C1), respectively and slowly dripping solutions (B3) and (C1) in the solution (A3) until a mixed solution is formed under conditions by performing ultrasonic shaking at frequency of 200-400KW and stirring at centrifugal speed of 500-800 rpm, adding 70-80 pts. wt. film-forming agent, mixing and stirring uniformly.
