Problems solved by technology

[0003] The purpose of the present invention is to provide a double-layer solid wood composite floor and its preparation method, which solves the problem of excessive glue layers and excessive release of harmful gases in traditional three-layer or multi-layer composite wood flooring, and solves the problem of two-layer solid wood composite flooring at the same time. The floor is purely anti-deformation, poor stress capacity and the problem that the surface board is easily cracked from the seam when the temperature and humidity change

Abstract

A double-layer solid wood composite flooring, comprising a surface board (2) and a back board (1). Multiple through holes (11) are formed in the back board (1) in a hollowed-out manner. A glue layer is provided between the surface board (2) and the back board (1), a double-layer wooded board structure is formed by means of hot pressing; the wood textures of the surface board (2) and the back board (1) are in the same direction. Wood blocks (3), perpendicular to the textures of the surface board (2) and the back board (1) and corresponding to the contours of the through holes (11), are embedded into the through holes (11). Further disclosed is a method for preparing the composite flooring. The composite flooring reduces harmful gas emissions, and improves the longitudinal strength of a flooring structure.

Description

technical field [0001] The invention relates to a double-layer solid wood composite floor and a preparation method thereof. Background technique [0002] With the continuous development of the solid wood composite flooring industry, users have higher and higher requirements for the environmental protection performance of the solid wood composite flooring. The traditional three-layer or multi-layer solid wood composite flooring process is relatively complicated, and there is a problem of excessive release of harmful gases in many glue layers. The traditional two-layer solid wood composite floor has the disadvantages of low longitudinal strength and cannot process large-format floors due to its pure two-layer vertical and horizontal structure. In the length direction, when the temperature and humidity change, the surface board is very easy to crack from the seam. There is an urgent need for a double-layer solid wood composite floor and its preparation method to solve the pro...
