Problems solved by technology

Commercially available composite floor substrates have problems such as the use of wood with different densities, the addition of cheap wood chips to the raw materials, the lack of reasonable pre-treatment of the wood, or the rough production process, which leads to poor performance of composite floor substrates and high formaldehyde emission. large, causing environmental pollution, which limits the promotion of composite flooring

Embodiment 1

[0038] A preparation method of a green and environment-friendly composite floor substrate, which 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, stacking the first raw material and the second raw material in a dry and ventilated place respectively, forming a first stack and a second stack, and sending them to the first stack and the second stack respectively Pass the first hot air and the second hot air into the stack, control the temperature...

[0056] A preparation method of a green and environment-friendly composite floor substrate, which comprises the following steps:

[0057] 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;

[0058] Step 2, stacking the first raw material and the second raw material in a dry and ventilated place respectively, forming a first stack and a second stack, and sending them to the first stack and the second stack respectively Pass the first hot air and the second hot air into the stack, control the...

Embodiment 3

[0074] A preparation method of a green and environment-friendly composite floor substrate, which comprises the following steps:

[0075] 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 24mm 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;

[0076] Step 2, stacking the first raw material and the second raw material in a dry and ventilated place respectively, forming a first stack and a second stack, and sending them to the first stack and the second stack respectively Pass the first hot air and the second hot air into the stack, control the temperature in the s...

Abstract

The invention discloses a preparing method for an environment-friendly composite floor base material. The preparing method includes the following steps that firstly, early wood and late wood are selected, and first raw materials and second raw materials are obtained; secondly, the first raw materials and the second raw materials are stacked respectively, and a pretreated first raw material is obtained; thirdly, the pretreated first raw material is put into a cooking tank to be cooked and is then subjected to fiber separation through an overheating mill, and first wood fiber is obtained; fourthly, a pretreated second raw material is treated according to the method in the third step, and second wood fiber is obtained; fifthly, the first wood fiber and the second wood fiber are mixed to obtain mixed fiber, then glue applying and hot pressing are conducted, and a floor base material is obtained; and sixthly, the floor base material is subjected to cooling hardening and tempering and sanding sawing, and the composite floor base material is obtained. The prepared composite floor base material has the beneficial effects of being high in strength, resistant to impacts, good in humidity resistance, environment-friendly and high in popularization value.

Description

technical field [0001] The invention relates to the field of wood processing. More specifically, the invention relates to a method for preparing a green and environment-friendly composite floor 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 t...
