Manufacturing method of hollow microsphere wood plastic composite board

The invention discloses a hollow microsphere wood plastic composite board and a manufacturing method of the hollow microsphere wood plastic composite board. In order to achieve the aims of manufacturing of a high-strength sound suction heat isolation wood plastic composite board and solving the problem that a vacuum environment cannot be formed in the wood material, the manufacturing method of the hollow microsphere wood plastic composite board is provided. The method comprises steps of material preparation, raw material pretreatment, plastic sheet preparation, roller mixing, vacuum tube paving, slab layered paving, hot pressing and cold pressing and later-period machining. The method has the beneficial effects that the sealed vacuum environment is formed in the wood plastic composite board, and therefore the wood plastic composite board has the part of characteristics of a vacuum material, the temperature and sound isolation property of the wood plastic composite board can be improved, the manufactured hollo
