NOVELTY - A graphene-silicone modified acrylate aqueous heat-dissipating coating having core-shell structure comprises 1-20 pts. wt. graphene, 40-60 pts. wt. mixed resin monomer, 1-20 pts. wt. high thermal conductivity filler, 1-5 pts. wt. initiator, 1-5 pts. wt. emulsifier, 0.1-1 pt. wt. hydrolysis inhibitor, 1-5 pts. wt. additives, and 5-2 pts. wt. deionized water. USE - Graphene-silicone modified acrylate aqueous heat-dissipating coating. ADVANTAGE - The graphene-silicone modified acrylate aqueous heat-dissipating coating having core-shell structure is prepared by core-shell emulsion polymerization process. The coating is prepared by using a portion of mixed resin monomer as core emulsion, and another portion of mixed resin monomer as shell monomer. The in-situ polymerization of graphene during pre-polymerization of shell monomer improves dispersibility of graphene in aqueous resin. The cured film-forming graphene cross-linked with pre-polymerized portion of shell monomer is uniformly dispersed in coating to form heat conduction network for increasing radiation heat dissipation rate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene-silicone modified acrylate aqueous heat-dissipating coating having core-shell structure, which involves (1) mixing mixed resin monomer, emulsifier and deionized water to obtain mixed resin monomer pre-emulsion, (2)adding prepared mixed resin monomer pre-emulsion into separating funnel, and adding aqueous solution of initiator into another separating funnel, adding deionized water and hydrolysis inhibitor to three-necked bottom flask equipped with stirrer and reflux condenser, stirring, and heating to 85 degrees C, dripping mixed resin monomer pre-emulsion and initiator mixture for 2 hours, heat preserving for 1 hour, and filtering the material to obtain core emulsion, (3) and pouring the core emulsion into three-necked flask, raising the temperature to 85 degrees C, stirring, mixing mixed resin monomer and graphene and placing in separating funnel, charging mixed solution of initiator and deionized water into another separating funnel, and dripping liquid in two separating funnel to three-necked flask for 2 hours, heat preserving for 1 hour to filter out material, pouring into mixing tank, and adding high thermal conductivity filler and additive into mixing tank, stirring and dispersing at high temperature for 2 hours under water cooling conditions, and leaving still for 1 hour.
