▎ 摘  要

NOVELTY - A heat-conductive water vapor barrier coating stock solution comprises 15-40 %mass base resin, 5-15 %mass sheet filler, 2-5 %mass spherical filler, 50-75 %mass solvent, 0.1-0.5 %mass silane coupling agent and 0.1-0.5 %mass curing agent. USE - The heat-conductive water vapor barrier coating is used in the fields of solar cells, organic LED protection, electronic material encapsulation and packaging (claimed). ADVANTAGE - The coating has high thermal conductivity, excellent water vapor barrier performance, excellent aging resistance, environmental stability and temperature resistance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: a preparation method of the heat-conductive water vapor barrier coating stock solution comprising (i) putting sheet filler, spherical filler and silane coupling agent into ball mill for ball milling to obtain mixed powder and (ii) uniformly mixing the mixed powder obtained in step (i) with base resin, solvent and curing agent to obtain the heat-conductive water vapor barrier coating stock solution; and a heat-conductive water vapor barrier coating obtained by coating the coating stock solution on a base material and evaporating the solvent and drying to obtain the product.
