▎ 摘　　要

NOVELTY - Preparation of high heat-conductivity pressure-sensitive adhesive includes adding graphene powder and boron nitride powder into a planetary mixer or kneader, stirring to mix uniformly, adding thermally conductive carbon material, fully mixing, obtaining the composite heat-conductive filler, preparing ethyl acetate solution, adding surface treatment agent and composite heat-conductive filler, heating and boiling, reflux steam condensing ethyl acetate into solution, reacting for hours, filtering, washing the filter cake with ethyl acetate, drying and crushing to obtain fluffy powder. USE - Preparation of high heat-conductivity pressure-sensitive adhesive. ADVANTAGE - The method can form heat conductive network more efficiently, does not generate agglomeration phenomenon, and provides pressure-sensitive adhesive with relatively high heat-conductivity. DETAILED DESCRIPTION - Preparation of high heat-conductivity pressure-sensitive adhesive comprises preparing composite heat-conductive filler by adding graphene powder and boron nitride powder into a planetary mixer or kneader, stirring to mix uniformly, adding thermally conductive carbon material, fully mixing, and obtaining the composite heat-conductive filler, preparing modified composite heat-conductive filler by wet processing comprising preparing ethyl acetate solution, adding surface treatment agent and composite heat-conductive filler, heating and boiling, reflux steam condensing ethyl acetate into solution, reacting for hours, filtering, washing the filter cake with ethyl acetate, drying, crushing by crusher to obtain fluffy powder, combining the modified composite heat-conductive filler and pressure-sensitive adhesive, uniformly mixing by stirring at room temperature, and obtaining the product.
