▎ 摘  要

NOVELTY - High thermal conductivity anticorrosive paint comprises component A comprising 21-31 wt.% epoxy resin, 5-13 wt.% boron nitride (BN) nano flakes, 9-19 wt.% graphene, 3-8 wt.% lemon yellow, 2-6 wt.% titanium dioxide, 2-6 wt.% mica powder, 0.3-0.8 wt.% dispersant, 0.1-0.3 wt.% leveling agent and 33-42 wt.% mixed solvent, and a component B comprising 84-96 wt.% polyisocyanate, 0.06-0.30 wt.% catalyst and 5-10 wt.% mixed solvent. USE - Used as high thermal conductivity anticorrosive paint. ADVANTAGE - The paint: meets the anti-corrosion function and the heat conduction function; and has high thermal conductivity, excellent corrosion resistance, and simple preparation and convenient construction. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the high thermal conductivity anticorrosive paint, comprising (i) preparing component A by (ia) adding a mixed solvent of equal mass and epoxy resin to a container, heating and refluxing, stirring and dissolving the epoxy resin, and continuously stirring for 1 hour until the solution is is uniform to obtain an epoxy resin solution, and (ib) adding dispersant, leveling agent, lemon yellow, titanium dioxide, nanometer boron nitride flakes, graphene, mica powder and the mixed solvent (remaining amount) to the epoxy resin solution under stirring conditions, ultrasonically dispersing, grinding it is until fine, when the degree is less than 5 mu m, filtering the material, and (ii) preparing the component B by adding the catalyst and the mixed solvent to polyisocyanate under stirring conditions, and stirring and filtering.
