▎ 摘　　要

NOVELTY - Integrated material comprises a splicing plate, which includes a waterproof layer (11), an insulating layer (12), and a heating layer (13). The insulating layers are arranged between the waterproof layer and the heating layer. The waterproof layer is a polyurethane waterproof layer, and the insulating layer is provided with a rock wool protective insulating sheet. The heating layer includes a graphene heating film layer (31) and a substrate layer (32). The substrate layer is arranged on both sides of the graphene heating film layer. USE - Integrated material for use in a material-preparation system for base layer construction and material preparation of an insulating building material i.e. integrated wallboard. ADVANTAGE - The waterproof layer can improve the waterproof and moisture-proof performance of the decorative wallboard, the insulating plate improves the heat preservation and heat-resistant performance of wallboard. The integrated material is integrated with waterproof and heat preservation, and has self-heating function. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing an integrated material for base construction DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of a splice plate. 11Waterproof layer 12Insulating layer 13Heating layer 31Graphene heating film layer 32Substrate layer
