▎ 摘　　要

NOVELTY - The wallboard has a graphene layer provided with first and second plate layers, first and second sound insulation cotton layers and an aluminum alloy plate layer. The aluminum alloy plate layer is arranged on a hollow aluminum alloy plate for filling wood in the aluminum alloy plate. An edge of wall is sealed by hot melt adhesive. The aluminum alloy plate is provided with multiple rib plates. USE - Environment-friendly wallboard. ADVANTAGE - The wallboard is light in weight, and can increase full-utilization rate of wood, and has high structural intensity, and better sound insulation effect. The wallboard is not moistured by deformation. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of an environment-friendly wallboard.
