Abstract

The invention discloses a composite interior wallboard with sandwich hollow fabric and a preparation method of the composite interior wallboard, and belongs to the technical field of composite building materials. The composite interior wallboard comprises the following raw materials in parts by weight: 20-70 parts of hollow fabric, 20-70 parts of resin, 10-30 parts of fillers, 1-30 parts of adhesives, 1-30 parts of putty powder and 0.1-10 parts of curing agents, as well as 1-20 parts of glass fiber cloth. According to the composite interior wallboard disclosed by the invention, the glass fiber cloth is added on both sides of the hollow fabric, so that the weight of the interior wallboard is reduced, the strength of the interior wallboard is improved, and the impact resistance of the interior wallboard is improved; a unique woven hollow structure improves the overall heat preservation performance of the composite interior wallboard, and has the soundproofing effect; and besides, the fillers including aluminum hydroxide, calcium carbonate, diatomaceous earth, perlite powder, glass beads and the like are used in a surface decoration layer, so that the flame resistance of the interior wallboard is improved, the strength of the interior wallboard is also further improved, and the wear resistance of the interior wallboard is improved.

Description
