▎ 摘  要

NOVELTY - Lightweight reinforced gypsum board comprises 55-65 pts. wt. desulfurized gypsum powder, 6-10 pts. wt. cement, 1-3 pts. wt. foamed polypropylene particles, and 25-35 pts. wt. graphene slurry. The concentration of graphene in the graphene slurry is 0.1-0.2 wt.%. USE - Lightweight reinforced gypsum board. ADVANTAGE - The lightweight reinforced gypsum board is cost-effective, that retains all the advantages of gypsum board, and achieves the goal of weight reduction and increase strength. It is directly coupled with the existing processing technology, without the need for new production lines or modification of existing production equipment. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing lightweight reinforced gypsum board, which involves: (A) pouring all the raw materials into the stirring tank, mix and stir uniformly; (B) injecting the uniformly mixed and stirred raw materials into the mold for compression molding, and natural curing after molding; (C) transporting the product after molding and curing into the drying room and continue curing at 100-120 degrees C; and (D) stacking the products that have been maintained into finished products.
