Polyvinyl chloride foam has the advantage of higher strength, but poorer thermal and moisture insulation properties.

The invention also discloses a foaming plate made of the PVC composite material, and a matched production method, equipment and floor, so that the prepared PVC product has high structural strength, good foaming performance and satisfactory silencing effect; although the strength is high, the heat preservation and moisture resistance are poor.
