Embodiment 1

[0015] The specific manufacturing method of the three-layer carbonized wood composite floor comprises the following steps: 1. preparation of the surface material of the carbonized wood composite floor; 2. preparation of the core layer of the carbonized wood composite floor; 3. preparation of the bottom layer of the carbonized wood composite floor.

[0016] 1. Preparation of carbonized wood composite floor surface material: carbonize the 22mm-thick surface blank at a temperature of 180°C; Divided into three pieces of carbonized wood surface finished products with a thickness of 6mm;

[0017] 2. Preparation of the core layer of carbonized wood composite floor: dry the fast-growing material blank until its moisture content is about 8%, and process it into a fast-growing material sheet 4 according to the specification and size of the floor. The side of the sheet 4 is coated with urea-formaldehyde resin adhesive, and the amount of glue applied is 300g / m 2 , the thin plates 4 are ...

Abstract

The invention relates to a carbonized composite floor and relative production, wherein it surface is made from the carbonized solid wood; the core layer of three layer is formed by solid composite plate; the bottom layer is made from shear single plate or carbonized plate; said three plates are adhered by adhesive; the core layer is made by slicing; the blank of core plate is adhered by single-layer plates that alternatively arranged; the single-layer plates are adhered by several sheets. And the production comprises: preparing the surface layer, core layer and bottom layer; then selecting the bottom material and the shear single plate. The invention has the advantages that: the invention can reduce the surface plate const, with better size stability.

Description

technical field [0001] The invention relates to a specific structure and manufacturing process of a composite wood floor, which belongs to the technical field of wood floor production. Background technique [0002] Along with the continuous improvement of people's living standards and the improvement of living conditions, wooden floor has been widely and generally used as a kind of ground laying material. At present, known wood flooring can be roughly divided into three categories: solid wood flooring, solid wood composite flooring and laminated flooring. Among them, composite flooring can appear in multiple types according to the difference in its composite materials and structures. As a natural ecological environment material, wood often has special visual, tactile, acoustic and temperature and humidity control characteristics compared with other materials. However, related to this, wood products will also vary with the use environment. Drying shrinkage and wet swelling o...
