High-stability two-layer solid wood composite floor and preparation process thereof

Abstract

The invention belongs to the technical field of wood floor design and manufacturing, and relates to a solid wood composite floor, in particular to a high-stability two-layer solid wood composite floor. The high-stability two-layer solid wood composite floor is formed by laminating a surface board layer and a base material layer through cold pressing, wherein the back surface of the surface board layer is provided with a plurality of stress release grooves with the depths not larger than 1 / 3 of the thickness of the surface board layer, the direction of the stress release grooves is perpendicular to the grain direction of a surface board, and the grooves are parallel to one another. Two through grooves are formed in the portions, 1 / 3 width away from the edges of the base material layer, of the back surface of the base material layer respectively, wherein the width of each through groove ranges from 10 mm to 100 mm, and the depth of each through groove does not exceed 1 / 2 of the thicknessof the base material layer. The invention further discloses a preparation process of the floor. According to the floor, the thickness is decreased from 14-15mm to 6-14mm, the wood resource is more saved, the heat conduction path is shorter, the utilization of heat energy is facilitated, and the floor is particularly suitable for producing floors with smaller size specifications, installation of various jigsaw patterns such as herringbone jigsaw and fishbone jigsaw are easy to achieve, and diversified requirements of customers are met; and by adopting the cold-pressing aldehyde-free glue technology, the performance of the floor is more stable, formaldehyde is not released, and the floor is more environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of wood floor design and manufacture, and relates to a solid wood composite floor, in particular to a high-stability two-layer solid wood composite floor and a preparation process thereof. Background technique [0002] The three-layer solid wood composite floor includes a surface board, a core board and a back board. The three layers are criss-crossed and pressed together by glue. Fast-growing wood such as wood and pine is popular among consumers because of its natural wood texture, easy installation and maintenance, ideal hardness, wear resistance, scratch resistance, and easy cleaning. However, there are problems in the use of three-layer solid wood composite flooring: for example, the flatness of the paving ground is relatively high, and if the ground is uneven, it is easy to make noise. The three-layer solid wood composite floor has large specifications and a length of more than 1m. The installation met...
