Abstract

The invention relates to a PVC co-extruded foam floor and a preparation method thereof, belonging to the technical field of PVC foam floors. PVC co-extruded foam floor, including PVC foam core and plastic surface layer, PVC foam core includes first foam layer, second foam layer and crust layer, second foam layer covers first foam layer, knot The skin layer covers the second foam layer, and the layers of the PVC foam core are integrally connected; the plastic surface layer is at least covered on the upper surface of the skin layer; the first foam layer is a low-density foam layer, and the second foam layer is High-density foam layer; wood grain on plastic surface. The present invention is molded at one time through an improved foaming process; the PVC foam core of the present invention is not clearly distinguished from the first foam layer and the second foam layer in the prior art, and the thickness of the crust layer is thin. It has the advantages of clearer structure and higher overall strength; and it is more suitable for covering the plastic surface.

Description

Technical field

[0001] The present invention relates to a PVC co-extrusion foaming floor and a preparation method thereof, belonging to the technical field of PVC foaming floor. Background technique

[0002] The PVC foaming floor is usually used as an outdoor floor. The PVC foaming plate is typically melting the mixture of the PVC and the blowing agent through the extruder when produced, and the high temperature foam is used in the mold, and then cool mold. When used as the floor, take into account the surface strength and wear resistance, often need to be reiled in the surface of the foaming plate and then retrieve the plastic layer. In order to make the floor have textures of wood, the usual practice is to print wood grain by the embedded roller on the plastic layer of the packet.

[0003] A utility model, which is an authorized publication number, is a practical utility model of CN202685311U, which is disclosed a surface embossing machine for a foaming plate. The device accura...
