Abstract

The invention discloses a three-layer wood-plastic floor board and a preparation method thereof. The wood-plastic floor board consists of a floor board bottom layer, a floor board middle layer and a floor board top layer, wherein double-ingredient polyurethane elastomers are added into the top layer and the bottom layer; the wood -plastic floor board is obtained through hot pressing shaping. Through the formula design of different layers of the wood-plastic floor board and through the selection of the proper overlapping sequence for combination, the prepared wood-plastic floor board has good wear resistance, anti-impact performance, shock resistance, mechanical intensity and blocking performance; wide application is realized in the field of indoor decoration.

Description

technical field [0001] The invention belongs to the field of wood-plastic composite materials, and in particular relates to a three-layer wood-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. Traditional indoor floors are mostly made of wood, which has problems such as flammability, moisture, corrosion, water absorption expansion and drying shrinkage. Wood-plastic flooring is a kind of wood-plastic floor, which is mainly made of wood (wood cellulose, plant cellulose) as the base material, thermoplastic polymer materials (PE, PVC plastic) and processing aids, etc., mixed evenly and then heated and extruded by mold equipment. The high-tech green environmental protection material made has both the performance and characteristics of wood and plastic, a...
