Problems solved by technology

However, due to the large difference in heat shrinkage ratio between PVC material and stone powder (such as calcium carbonate) in the stone-plastic floor prepared by traditional methods, it is easy to form voids, air bubbles or air chambers of different sizes, resulting in The strength of the stone-plastic floor is not high, and the product performance is unstable

Abstract

The invention discloses an extrusion compound stone-plastic floor and a preparation method thereof. The stone-plastic floor comprises a substrate layer, a middle layer and a wear-resistant layer, wherein a two-component polyurethane elastomer is added to the substrate layer and the wear-resistant layer, and the stone-plastic floor is obtained through extrusion and hot press molding. By means of the two-component polyurethane elastomer added to the stone-plastic floor and the performance of the polyurethane elastomer, air gaps, bubbles or air chambers caused by large shrinkage ratio differencebetween a PVC material and marble powder are eliminated, properties such as wear resistance, impact resistance, shock resistance, mechanical strength, barrier property and the like of the stone-plastic floor are improved, and the stone-plastic floor is extensively applied to the field of indoor decoration.

Description

technical field [0001] The invention belongs to the technical field of stone-plastic floor processing, and in particular relates to an extruded composite stone-plastic floor and a preparation method thereof. Background technique [0002] Flooring has been used more and more in interior decoration, and flooring includes solid wood flooring, laminated wood flooring, solid wood composite flooring, bamboo wood flooring, and cork flooring. Solid wood flooring or composite wood flooring requires the use of a large amount of wood, which is not conducive to environmental protection. The floor surface has poor impact resistance, and cannot be well waterproof, moisture-proof, and corrosion-resistant. The daily maintenance workload is large, and the later maintenance and use costs are high. Stone-plastic flooring is loved by consumers because of its waterproof, wear-resistant, and long service life. However, due to the large difference in heat shrinkage ratio between PVC material and ...
