Problems solved by technology

[0004] There are many kinds of chemical agents for preservative treatment of plywood, but the use of various traditional wood preservatives (such as chromium-added copper arsenate CCA, etc.) The impact of these preservatives on environmental safety and human health runs counter to the environmental protection characteristics of wood itself

Embodiment l

[0019] Wood section rotary cutting, veneer drying, veneer cutting, obtain the veneer of prepared plywood, then veneer is carried out anti-corrosion treatment as follows:

[0020] (1) Configure antiseptic solution: configure antiseptic solution with furfuryl alcohol and ammonium borate in a molar ratio of 1:2;

[0021] (2) Anti-corrosion solution treatment of the veneer: put the veneer into the vacuum pressure tank, connect the vacuum equipment and the pressurization equipment (that is, turn off the pressurization pump when the vacuum pump is started to vacuum; turn off the vacuum pump when the pressurization pump is turned on), and turn on Vacuumize the vacuum pump to make the relative vacuum in the vacuum pressurized tank reach -0.08 MPa. After keeping for 50 minutes, turn off the vacuum pump and introduce the prepared antiseptic solution until the relative vacuum in the vacuum pressurized tank is 1Mpa. The booster pump continues to feed the antiseptic solution into the vacuu...

Embodiment 2

[0026] Wood section rotary cutting, veneer drying, veneer cutting, obtain the veneer of prepared plywood, then veneer is carried out anti-corrosion treatment as follows:

[0027] (1) Configure the antiseptic solution: configure the antiseptic solution with furfuryl alcohol and ammonium borate in a molar ratio of 1:2.3;

[0028](2) Anti-corrosion solution treatment of the veneer: put the veneer into the vacuum pressure tank, connect the vacuum equipment and the pressurization equipment (that is, turn off the pressurization pump when the vacuum pump is started to vacuum; turn off the vacuum pump when the pressurization pump is turned on), and turn on Vacuumize the vacuum pump to make the relative vacuum in the vacuum pressurized tank reach -0.085MPa, keep the vacuum pump for 55 minutes, and then import the pre-prepared antiseptic solution until the relative vacuum in the vacuum pressurized tank is 1.5Mpa. Turn on the pressurizing pump, continue to feed the anti-corrosion solutio...

Embodiment 3

[0033] Wood section rotary cutting, veneer drying, veneer cutting, obtain the veneer of prepared plywood, then veneer is carried out anti-corrosion treatment as follows:

[0034] (1) Configure antiseptic solution: configure antiseptic solution with furfuryl alcohol and ammonium borate in a molar ratio of 1:2.8;

[0035] (2) Anti-corrosion solution treatment of the veneer: put the veneer into the vacuum pressure tank, connect the vacuum equipment and the pressurization equipment (that is, turn off the pressurization pump when the vacuum pump is started to vacuum; turn off the vacuum pump when the pressurization pump is turned on), and turn on Vacuumize the vacuum pump to make the relative vacuum in the vacuum pressurized tank reach -0.09MPa. After keeping for 60 minutes, turn off the vacuum pump and introduce the prepared antiseptic solution until the relative vacuum in the vacuum pressurized tank is 2.0Mpa. Turn on the pressurizing pump, continue to feed the anti-corrosion sol...

Abstract

The invention provides a preparation method of preserved plywood. The method is that a special mixed preserving solution is adopted to perform preserving soaking treatment for a single board in a vacuum state; the single board is processed by pressure reduction vacuum pumping treatment in order to fully absorb a preservative; then the single board is pressurized so that the preservative can fully permeate the board. The preserved plywood prepared by the method has the advantages that the loss rate of boron in the single board is small; the effects on resisting termite and rot fungi are improved; the preserving performance is greatly improved; the preserving effect is obviously increased; the service life of the preserved plywood is prolonged.

Description

technical field [0001] The invention relates to a plywood, in particular to a preparation method of an anti-corrosion plywood. Background technique [0002] my country's timber industry is in the process of transforming from using mainly natural forest timber to mainly utilizing plantation forest timber. Plantation forest fast-growing small timber will be the main timber raw material in my country in the future. However, fast-growing wood in artificial forests is prone to decay, insects, and mildew. Therefore, wood protection will play a role in prolonging the life of wood and reducing the waste caused by downgrading, downgrading, and discarding wood due to decay and insects. It plays the role of improving the quality of wood products and increasing the functions of wood products. Reduce the loss and waste of wood due to rot and other reasons, prolong the service life of wood products, reduce the demand for wood resources in related industries (including wood, furniture, co...
