Solid wood PVC stone-plastic double-layer composite floor

Abstract

The invention discloses a solid wood PVC stone-plastic double-layer composite floor, and belongs to the field of floors. The floor is formed by bonding a panel at the upper layer with a substrate at the lower layer, the panel is a solid wood plate, and the substrate is a PVC stone-plastic plate; the thickness of the substrate is higher than that of the panel; the substrate is internally provided with a through passage in the length direction; the upper surface of the substrate is provided with substrate glue storage grooves in the length direction or the lower surface of the panel is providedwith panel glue storage grooves in the length direction; the substrate glue storage grooves are adjacently and continuously formed in the width direction of the substrate, and the panel glue storage grooves are adjacently and continuously formed in the width direction of the panel. The PVC stone-plastic plate is a PVC stone-plastic base material, and the PVC stone-plastic basic material is prepared according to the following steps of blending raw materials and carrying out heating, generating air pores, carrying out extrusion molding, and carrying out cooling for shaping. According to the solid wood PVC stone-plastic double-layer composite floor, the production cost of the double-layer composite floor is reduced, the ecological environment is protected, and the situations can be effectively prevented from occurring that the double-layer composite floor is unglued and deformed.

Description

technical field [0001] The invention relates to a floor, in particular to a solid wood, PVC, stone-plastic double-layer composite floor. Background technique [0002] At present, composite solid wood flooring is mainly based on multi-layer solid wood composite, and its performance is closer to pure solid wood with three layers. The three-layer solid wood composite floor is composed of three layers of thin solid wood boards through a more complex process. When the three layers are composited, the thinner bottom and surface layer wood grains are arranged vertically, and the thicker middle layer wood grains are arranged horizontally, thus neutralizing the natural deformation of the wood. The surface layer of this three-layer solid wood composite floor is made of high-quality wood (such as: oak, maple, teak, Burmese mahogany, hickory and walnut, etc.), and the middle layer and bottom layer are fast-growing materials with better elasticity ( Such as: pine, poplar, etc.), can ef...

Problems solved by technology

[0007] The purpose of the present invention is to overcome the disadvantages of the existing two-layer structure composite wood floor, which is high in production cost, destroys the ecological environment, and is prone to glue opening and deformation, and provides a solid wood PVC stone-plastic double-layer composite floor, which reduces the double The production cost of the double-layer composite floor is reduced, the ecological environment is protected, and the occurrence of glue opening and deformation of the double-layer composite floor is effectively avoided.
