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. my country's timber industry is in the process of transition from natural forest timber to plantation forest timber. Plantation forest fast-growing small timber will be the main timber raw material in the future, but plantation forest fast-growing timber is prone to decay and insects. , mildew, so wood protection will play a role in prolonging the life of wood, reducing the waste of wood due to decay and insects, and can also improve the quality of wood products and increase the functions of wood products in related industries. Plywood can solve the problem of wood resources. Insufficient problem, but the corrosion resistance of existing plywood is poor, therefore, how to carry out anticorrosion treatment to plywood scientifically and environmentally friendly is a technical problem that needs to be solved now
[0003] With the infiltration of technical research, the treated plywood can basically meet the anti-corrosion requirements, but the anti-microbial attack performance is poor, and the preservative used to treat the plywood is easy to lose during use, which affects the service life of the anti-corrosion plywood

Abstract

The invention belongs to the technical field of processing anti-corrosion plywood, and in particular relates to a preparation method of weather-resistant anti-corrosion plywood, including a veneer anti-corrosion treatment method of vacuum immersion in anti-corrosion liquid, a method of drying anti-corrosion veneer by electromagnetic wave drying and an adhesive preparation. Compared with the prior art, the present invention has the following advantages: the antiseptic liquid in the present invention is friendly to the environment and has good resistance to various microorganisms. Through the cooperation of vacuum conditions, the antiseptic liquid has good permeability in the veneer and can Uniform, and then use electromagnetic wave sealing treatment, which can make the ingredients in the antiseptic solution better combined in the veneer, which can effectively reduce the loss of active ingredients and improve the durability of the antiseptic effect; the adhesive can avoid the problem of excessive aging and avoid After hot pressing, the glue is opened, so that the obtained plywood has a stable structure, good weather resistance, effective and long-lasting anti-corrosion effect, and remarkable economic benefits.
