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

[0038] The invention provides a kind of preparation method of composite floor base material, it comprises the following steps:

[0039] Step 1. Select the early wood and late wood of Chinese fir with similar density, send the early wood and late wood to the chipper for cutting, and then transport them to the vibrating screen to screen out multiple pieces with a length of 16mm, a width of 15mm, and a thickness of 3mm. 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;

[0040] 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 p...

Embodiment 2

[0055] The invention provides a kind of preparation method of composite floor base material, it comprises the following steps:

[0056] Step 1. Select the early wood and late wood of Chinese fir 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 multiple pieces with a length of 30mm, a width of 25mm and a thickness of 5mm. 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;

[0057] 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 put the first raw material into the fumigation box according to the sequence of an...

Embodiment 3

[0072] The invention provides a kind of preparation method of composite floor base material, it comprises the following steps:

[0073] Step 1. Select the early wood and late wood of cork pine 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 23mm long, 20mm wide, thick 4mm 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 successively;

[0074] 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 put the first raw material into the fumigation box according to the order of an equal portion of the fi...

Abstract

The invention discloses a preparation method of a composite floor base material. The preparation method comprises the following steps that firstly, early wood and late wood are selected, and a first raw material and a second raw material are obtained; secondly, the first raw material is subjected to fumigation treatment to obtain the pretreated first raw material; thirdly; the second raw material is pretreated according to the method in the second step to obtain the pretreated second raw material; fourthly, the pretreated first raw material and the pretreated second raw material are boiled and subjected to fiber separation through a defibrator, and a first wood fiber and a second wood fiber are obtained; fifthly, the first wood fiber and the second wood fiber are mixed to obtain a mixed fiber; sixthly, a floor base material is prepared through gluing and hot pressing; and seventhly, the floor base material is subjected to cooling hardening and tempering and sanding cutting to obtain the composite floor base material. The composite floor base material is high in strength, resistant to impacts, good in dampproof performance, good in stability, not prone to buckling deformation and low in formaldehyde emission.

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 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 adhesive. Th...
