▎ 摘　　要

NOVELTY - Preparing high thermal conductivity cement clinker comprises (i) ultrasonically dispersing graphene oxide into isopropanol solution to obtain graphene oxide-isopropyl alcohol dispersion, (ii) mixing cement clinker powder into graphene oxide-isopropyl alcohol dispersion in the step (i), continuously stirring until all graphene oxide is adsorbed to the surface of cement clinker, then separating the obtained wet material into a liquid to obtain cement clinker coated with graphene oxide, (iii) annealing the cement clinker obtained in the step (ii) at a set temperature, removing the residual isopropanol, and functional group in the reduced graphene oxide to obtain graphene-coated cement clinker. USE - The high thermal conductivity cement clinker, and/or high thermal conductivity cement product is useful in building field (claimed). ADVANTAGE - The method: improves thermal conductivity of cement product; and avoids the problems of adaptability of cement product caused by the addition of the graphene dispersant. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing high thermal conductivity cement product, comprising compounding high heat conductive cement clinker, gypsum, and mixed material.
