▎ 摘　　要

NOVELTY - Gypsum-based hydrophobic composite material with self-cleaning function comprises 50-75 pts. wt. hemihydrate gypsum, 2-8 pts. wt. graphene solution, 5-15 pts. wt. mineral admixture, 0.5-3 pts. wt. hydrophobic modifier, 0.1-2 pts. wt. silane coupling agent, and 20-30 pts. wt. water. USE - The composite material is useful in building material. ADVANTAGE - The composite material has excellent decorative and self-cleaning function, low heat conducting coefficient, and good water resistance. The method has strong implementation performance, realizes high additional value utilization of industrial by-product gypsums, and can be widely applied to non-bearing wall or decorative material of industrial and civil building. The hydrophilic can graphene is more uniform, more stable and more stable in the plaster slurry for a long time. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparing gypsum-based hydrophobic composite material with self-cleaning function.
