Two-layer solid wood composite floorboard and manufacturing method thereof

Abstract

A two-layer solid wood composite floor and a preparation method thereof, which belong to the technical field of wood processing. The two-layer solid wood composite floor is made by bonding a surface plate and a base plate. The wood grain direction of the surface plate and the base plate is the same, and one side of the base plate has a transverse groove , one or the other side of the substrate with grooves is bonded to the back of the panel to make solid wood composite flooring. The preparation method is completed by adopting the steps of separately drying the surface plate and the base plate, slotting the base plate, hot-pressing the surface plate and the base plate, and the like. The solid wood composite floor of the present invention is a two-layer floor combined with wood grain vertically, which saves wood resources, reduces costs, reduces the amount of glue coating, reduces the amount of formaldehyde release, ensures environmental protection, and solves the stress caused by the two layers being in the same direction. problem, to ensure the stability of the floor.

Description

Technical field: [0001] The invention belongs to the technical field of wood processing and relates to a solid wood floor. Background technique: [0002] Solid wood flooring is divided into single solid wood flooring and composite solid wood flooring. Single solid wood flooring is processed from a single wood with high value. The production process is simple, but the cost of raw materials is high; One layer of wood with high use value and quality is used as the surface board, and the other layers use low-cost fast-growing wood as the substrate, which reduces the cost of materials, but the production process is relatively complicated. At present, the composite solid wood flooring is three or more layers. The reason is that if two layers of composite solid wood flooring are made, the substrate can only be one layer, and the grain must be consistent with the direction of the surface board, that is, the length direction is along the grain. , such a final product is very prone t...

[0002] Solid wood flooring is divided into single solid wood flooring and composite solid wood flooring. Single solid wood flooring is processed from a single wood with high value. The production process is simple, but the cost of raw materials is high; One layer of wood with high use value and high quality is used as the surface board, and the other layers use low-cost fast-growing wood as the substrate, which reduces the cost of materials, but the production process is relatively complicated

At present, the composite solid wood flooring is three or more layers. The reason is that if two layers of composite solid wood flooring are made, the substrate can only be one layer, and the grain must be consistent with the direction of the surface board, that is, the length direction is along the grain. , such a final product is very prone to warping, and there is no solution to this problem in the existing public information

However, if the substrate is perpendicular to the grain of the panel, the substrate needs to be spliced ​​segment by segment, and the strength cannot meet the requirements.
