Composite floor containing microsphere-foamed silicate-modified PVC and manufacturing method thereof

The invention relates to the technical field of plastic processing, in particular to a composite plastic floor containing microsphere-foamed PVC. The composite floor comprises a microsphere-foamed damping layer, a reinforcing layer, a microsphere-foamed printing base layer, a printing layer, a modified PU wear-resisting layer, an embossing layer, a UV curing glazing layer and the like. The produced floor is high in strength, good in wear resistance and heat preservation performance and free of plasticizer overflowing, solves the technical problems existing in existing floor industry and can replace a wooden floor.
