Problems solved by technology

[0002] Plywood is an important type of wood-based panels. Due to the characteristics of small deformation, large format, inconvenient construction, not easy to warp, and high tensile strength of transverse grains, plywood is widely used in furniture, carriages, shipbuilding, military industry, packaging and other industrial sectors. It has been widely used, but because plywood is a kind of wooden material, it is easy to be attacked by bacteria, insects, and marine borers, and it is easy to rot. Therefore, ordinary plywood has low corrosion resistance and poor insect resistance, so its use is limited. Therefore, it is very necessary to carry out anti-corrosion treatment to plywood. With the continuous improvement of plywood processing technology, chemical agents are usually used to carry out anti-corrosion treatment on plywood in the prior art. Although it can effectively prevent microorganisms from invading wood and play a role in anti-corrosion, However, these preservatives have a certain impact on environmental safety and human health, and the use of some raw materials is gradually restricted or banned. Therefore, low toxicity, high efficiency and antiseptic effect on plywood are currently technical problems that need to be studied and solved.

Embodiment 1

[0013] A preparation method of insect-proof plywood, comprising insect-proof treatment of veneer and insect-proof treatment of glue, the thickness of the veneer is 1.2mm, and the water content is 11%;

[0014] The method of veneer anti-insect treatment is as follows: immerse the veneer in the treatment solution, each 100ml treatment solution contains 3g hydrogen peroxide and 1.2g alkone, immerse it under vacuum for 1.8 hours, then pressurize to 0.7MPa and keep it for 35 minutes, take it out and dry it When the moisture content is 6%, it can be processed in a fumigation and drying furnace for 28 minutes. The smoke material in the fumigation and drying furnace is paulownia wood after acid treatment;

[0015] The anti-insect treatment method of the adhesive is to add composite particles equivalent to 6% of its weight in the adhesive, and the preparation method of the composite particles is: alkone, carbon nanotubes and polyvinyl alcohol are mixed in a weight ratio of 5 : 9:1 mixi...

Embodiment 2

[0020] A preparation method of insect-proof plywood, comprising insect-proof treatment of veneer and insect-proof treatment of glue, the thickness of the veneer is 1.2mm, and the water content is 10%;

Abstract

The invention belongs to the technical field of plywood machining, and particularly relates to a preparation method of insect-preventing plywood. The preparation method comprises a veneer insect prevention treatment mode and an adhesive insect prevention treatment mode, specifically, the veneer insect prevention treatment mode comprises the steps of treating fluid soaking and paulownia wood fumigation after acid treatment, and according to the adhesive insect prevention treatment mode, composite particles with the insect preventing effect are added into an adhesive. Compared with the prior art, the preparation method has the following advantages that the plywood prepared through the preparation method can well defend against white ants and decay fungi, the erosion resistance of veneer can be improved, the durability of the insect prevention effect is good, and the service life of the plywood is prolonged.
