Embodiment 1
[0038] A method for manufacturing an anti-deformation solid wood composite board, as attached figure 1 , attached Image 6 , attached Figure 7 , attached Figure 9 As shown, it includes the following steps: the first step is to cut the log into 2mm veneers, select the first-grade veneer as the surface layer, select the second-grade veneer as the bottom layer, and select the third-grade veneer as the middle layer board and dried to a moisture content of 6-12%;
[0039] The second step is to use environmentally friendly E0 grade glue with a mass concentration of 70% to evenly apply glue on the contact surface between the surface plywood and the middle plywood, and apply glue on both sides of the middle plywood, press the composite board with a press, and cut the composite board into slats of the same specification;
[0040]The third step is to apply glue on the bottom surface of the surface layer slats, and apply glue on both sides of the middle layer slats. First, select t...
Embodiment 2
[0045] In the manufacturing method of the anti-deformation solid wood composite board described in this embodiment, in the first step, the log is stuck on a rotary cutter and cut into veneers with a thickness of 2mm, and the first-level veneer is selected as the surface layer board, and the second-level veneer is selected. The veneer is used as the bottom layer, and the third-level veneer is used as the middle layer. The first-level veneer, the second-level veneer, and the third-level veneer are stored in categories, and the moisture content of the veneer is dried to 7 with a drum or a vacuum dryer. -11%.
Embodiment 3
[0047] In the manufacturing method of the anti-deformation solid wood composite board described in this embodiment, in the second step, the bottom surface of the upper panel is evenly coated with glue, the top surface of the lower panel is evenly coated with glue, and the two sides of the middle layer are evenly coated with glue. The glue is environmentally friendly E0 grade, glue quality The vegetable glue with a concentration of 65% and zero formaldehyde emission is pressed into a composite board, and the composite board is cut into slats of the same specification, and the width is made according to the required thickness of the board.

Abstract
The invention discloses a production method of a low-carbon environment-friendly anti-deformation solid wood composite plate. Poplars on roadside and phoenix trees and Paulownia trees in front and rear of the village are available now, but people use the trees for low-level purposes. The production method includes the steps of rotary-cutting log into 2mm veneers, selecting primary, secondary and tertiary veneers, and drying; gluing the plates with 70% glue of environment protection level E, press-fitting the plates with a press, cutting to obtain equal-specification slabs; gluing the surface slabs and the middle slabs, selecting three layers of transverse texture slabs as balance tension plates to make multi-layer plate stock, and cutting the multi-layer plate into wide battens; gluing the wide battens, splicing the wide battens once by an automatic splicer to form a multi-layer plate, sanding the multi-layer plate, fixing the thickness and adding decorative surfaces. Common wood resource is fully utilized to replace valuable wood resources, so that resources are saved, waste is turned into wealth, forest resources are protected forcibly and cost is lowered.
Description
technical field [0001] The invention relates to a production technology of a solid wood multilayer board, in particular to a production process and structure of a low-carbon, green, environment-friendly, energy-saving and deformation-resistant solid wood composite board. Background technique [0002] With the rapid development of the global economy, the continuous improvement of people's living standards, and the unrestrained growth of human consumption needs and desires, it has also brought enormous pressure to our earth. Global warming, carbon dioxide emissions Increasing day by day, so the entry of human beings into life is a hot topic of concern all over the world. Experts pointed out that the core of low-carbon economic development lies in low emission, high absorption and "carbon sustainability", and forest resources will play an important role and far-reaching significance in this regard, which is of great significance to the realization of low emission and high absor...
