▎ 摘　　要

NOVELTY - Paper surface gypsum board comprises a plate core and a surface protecting paper. The raw material of the plate core comprises gypsum clinker, expanded vermiculite, silicon ash, phase-change material, heat-conducting reinforcing material, reinforcing fiber and polyvinyl alcohol. The phase change material and heat-conducting reinforcing material are located in the interlayer space of expanded vermiculite. The board core further comprises foaming agent, starch, water reducing agent. The phase change material is emulsified paraffin, polyethylene glycol and lauric acid, the heat-conducting reinforcing material is carbon network, silicon carbide nanowires, metal nanowires, carbon nano-tube and graphene, preferably heat-conducting reinforcing material is silicon carbide heat-conducting reinforcing material, the reinforcing fiber is carbon fiber, asphalt-based carbon fiber, polypropylene fiber, glass fiber, graphene carbon fiber and gypsum whisker and reinforcing fiber is carbon fiber. USE - Used as a paper surface gypsum board. ADVANTAGE - The paper surface gypsum board: has good heat preservation performance; and phase change material is not easy to leak. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the paper surface gypsum board.
