The invention belongs to the technical field of buildings, and particularly relates to a wood-plastic flame-retardant wallboard. The wood-plastic flame-retardant wallboard sequentially comprises a first co-extrusion layer, a second co-extrusion layer, a third co-extrusion layer, a fourth co-extrusion layer and a fifth co-extrusion layer from top to bottom, the first co-extrusion layer and the fifth co-extrusion layer are the same and comprise plastic, a phosphorus flame retardant and an aluminum-magnesium flame retardant; the second co-extrusion layer and the fourth co-extrusion layer are the same and comprise plastic and an aluminum-magnesium flame retardant; and the third co-extrusion layer comprises plant fibers, plastic, an aluminum-magnesium flame retardant and a phosphorus flame retardant. By designing the flame-retardant co-extrusion fully-coated board and reasonably designing a specific formula in each co-extrusion layer, the flame retardance of the wood-plastic wallboard is ensured, and meanwhile, the mechanical property of the wood-plastic wallboard cannot be reduced.
本发明属于建筑技术领域，具体涉及一种木塑阻燃墙板。该木塑阻燃墙板，从上至下依次包括第一共挤层、第二共挤层、第三共挤层、第四共挤层和第五共挤层；所述第一共挤层和第五共挤层相同，包含塑料、磷系阻燃剂和铝镁阻燃剂；所述第二共挤层和第四共挤层相同，包含塑料和铝镁阻燃剂；第三共挤层包含植物纤维、塑料、铝镁阻燃剂和磷系阻燃剂。本申请通过设计阻燃共挤全包覆板材并且通过合理设计各共挤层中的特定配方，实现了木塑墙板在保证阻燃性的同时，其力学性能也不会下降。
