Problems solved by technology

The commercially available composite floor substrates have problems such as using wood with different densities, adding cheap wood chips to the raw materials, and the wood has not been properly pre-treated or the production process is rough, which leads to poor performance and low density of composite floor substrates. A large number of poor-quality composite floors cannot meet people's requirements for composite floors

Embodiment 1

[0036] A preparation method of a high-density composite floor substrate, comprising the following steps:

[0037] Step 1. Select the early wood and late wood of the same tree species with similar density respectively, send the early wood and late wood to the chipper for cutting, and then transport them to the vibrating screen to screen out a plurality of 16mm long, 15mm wide, thick 3mm wood chips, the wood chips obtained from the early wood are the first raw material, and the wood chips obtained from the late wood are the second raw material; the first raw material and the second raw material are respectively washed and air-washed in sequence;

[0038] Step 2: Divide the first raw material into three equal parts, spread one equal part of the first raw material on the bottom of the fumigation box, press a mesh plate on the upper part of the first raw material, Then, according to the order of one equal portion of the first raw material and one of the screen plates, put the first...

Abstract

The invention discloses a manufacturing method of a high-density composite floor base material. The manufacturing method comprises the following steps that firstly, early wood and late wood are selected, so that a first raw material and a second raw material are obtained; secondly, the first raw material is fumigated, so that the pre-treated first raw material is obtained; thirdly, the second raw material is pre-treated according to the method adopted in the second step, so that the pre-treated second raw material is obtained; fourthly, the pre-treated first raw material is sequentially placed in a boiling tank and a pressure tank to be treated and then taken out, fiber separation is conducted, and first wood fiber is obtained; fifthly, the pre-treated second raw material is treated according to the method adopted in the fourth step, and then second wood fiber is obtained; sixthly, the first wood fiber and the second wood fiber are mixed, synthetic fiber is obtained, sizing is conducted on the surface of the synthetic fiber, hot pressing is conducted, and then a floor base material is obtained; and seventhly, cooling, hardening and tempering, sanding and saw cutting are conducted on the floor base material, and then the composite floor base material is obtained. The composite floor base material is high in strength, environmentally friendly, good in waterproof performance, breathability and stability and high in density.

Description

technical field [0001] The invention relates to the field of wood processing. More specifically, the present invention relates to a method for preparing a high-density composite flooring substrate. Background technique [0002] As a decorative material, composite flooring is widely used in people's life and work. Moreover, with the improvement of people's material living standards, people's demand for composite flooring is increasing, and their quality requirements are also getting higher and higher. . The base material is the main body of the composite floor, which plays an important role in the tongue-and-groove connection, stable shape, and load bearing in actual use. The quality of the base material will directly affect the quality of the composite floor. [0003] The quality of the base material is affected by many factors, such as tree species and the combination of tree species, the control of the moisture content of the wood, the production process and the type of ...
