[0014] The beneficial effects of this utility model are:
[0015] (1) The high-density waterproof composite board of this utility model uses a polyvinyl alcohol environmentally friendly adhesive layer to easily bond and fix the reinforcing plate layer and the PVC base plate to both sides of the high-density board base.
