Embodiment 1

[0037] A method for manufacturing a low-carbon, environment-friendly and anti-deformation solid wood composite board, comprising the following steps: the first step is to cut the log into 2mm veneers, select the first-level veneer as the top layer board, and select the second-level veneer as the bottom layer Board, select the three-level veneer as the middle layer and dry the moisture content of 6-12%;

[0038] The second step is to use environmentally friendly E0 grade glue with a concentration of 70% to evenly coat the contact surface of the surface plywood and the middle plywood.

[0039] Glue and glue on both sides of the middle laminate, use a press to press into a composite board, 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 three layers of transverse grain

[0041] The slats are pl...

Embodiment 2

[0046] The manufacturing method of the low-carbon environmental protection anti-deformation solid wood composite board, the first step is to cut the log into a veneer with a thickness of 2mm on the rotary cutter, select the first-level veneer as the surface layer board, and select the second-level veneer. 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

[0048] In the manufacturing method of the low-carbon environment-friendly anti-deformation solid wood composite board, 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 concentration The 65% zero-formaldehyde-emission vegetable glue is pressed into a composite board, and the composite board is cut into slats of the same specification, and the width is made into the thickness of the board according to the requirements.

Abstract

The invention discloses a manufacturing method for a low-carbon and environmental-protection anti-deformation solid wood composite board. Roadside poplar trees and sycamore trees and kiri around the village grow into useful timber, but people often use the timber at a low level. The manufacturing method disclosed by the invention comprises the following steps of performing rotary cutting on logs into veneers of 2mm, picking out first-grade veneers, second-grade veneers and third-grade veneers, and drying; coating with environmental-protection E0 grade glue of which the concentration is 70 percent, pressing with a pressing machine and cutting into battens which are equal in specification; coating the battens of the surface layers and the battens of the middle layer with the glue; firstly manufacturing three layers of battens with cross grains as balance tension boards into a composite board, and cutting the composite board into broad battens; coating the broad battens with the glue, jointing the broad battens at a time by an automatic board jointing machine to manufacture a composite board, sanding, performing thickness defining, and adding a decorative surface. According to the manufacturing method disclosed by the invention, valuable timber resources are replaced by fully utilizing common timber resources, and therefore the resources are saved; waste is turned into treasure, forest resources are protected strongly, and the cost is reduced.

Description

Technical field [0001] The invention type involves a solid wood multi -layer production technology, especially the process and structure of low -carbon, green, environmentally friendly energy -saving and anti -deformation solid wood composite board. Background technique [0002] With the rapid development of the global economy, people's living standards are continuously improved, and human consumption demand and desire are also increasing. It has also brought tremendous pressure on our planet.The increasing day is increasing, so human beings entering low -carbon environmental protection life is a hot topic of attention around the world.Experts point out that the core of the development of the low -carbon economy is low emissions, high absorption and "carbon sustainability", and forest resources will play an important role and far -reaching significance for this, which is of great significance to realize the low emissions and high absorption of greenhouse gas.Therefore, strengthen...
