Preparation method of plywood for antibacterial and mildew-proof decoration

Abstract

The invention mainly relates to the technical field of machining of artificial boards, and discloses a preparation method of antibacterial mould-proof plywood for decoration. The preparation method comprises drying, dipping, freezing, gluing, hot pressing and arrangement; the method is simple, safe and nontoxic; the obtained plywood for decoration reaches the mould inhibition rate of 76.3%, and contains no poisonous chemical reagent; the human health is guaranteed in the preparation and use process of the plywood; a veneer is firstly dried at low temperature, so that the water content is lower than the water content of a conventional veneer, the activity of the mould remained in the veneer is inhibited, the moulding is inhibited, the absorption of treatment solution in later treatment process is promoted, and the production efficiency is improved; and the dried veneer is put in sodium selenite solution for ultrasonic dipping, so that the sodium selenite solution is fully infiltrated in the veneer to inhibit growth of infectious microbes, the binding force of lignin to cellulose is reduced, the softness of the veneer is improved, breakage is prevented, and the machining performance and the use performance of the plywood are improved.

Description

technical field [0001] The invention mainly relates to the technical field of wood-based panel processing, in particular to a preparation method of antibacterial and mildew-proof plywood for decoration. Background technique [0002] Plywood for decoration is used as decoration material for buildings, furniture, vehicles and ships. It is in close contact with human beings during use, and is used very frequently. Improper use can easily breed bacteria, cause mold, and cause great harm to human health. In addition, the currently used plywood for decoration uses a large amount of toxic reagents in order to inhibit the growth of mold. Although it can inhibit the mold of the plywood to a certain extent, the toxic components slowly emitted by the plywood also cause long-term harm to human health. Existing patent documents CN 104760095 B discloses a preparation method of anti-corrosion plywood, the veneer is vacuum-impregnated with anti-corrosion liquid, the anti-corrosion liquid is...

Problems solved by technology

[0002] Plywood for decoration is used as a decoration material for buildings, furniture, vehicles and ships. It is in close contact with human beings during use, and the frequency of use is extremely high. Improper use can easily breed bacteria, lead to mold, and cause great harm to human health. In addition, the currently used plywood for decoration uses a large amount of toxic reagents in order to inhibit the growth of mold. Although it can inhibit the mold of the plywood to a certain extent, the toxic components slowly emitted by the plywood also cause harm to human health for a long time. The existing patent document CN 104760095 B discloses a method for preparing anti-corrosion plywood. The veneer is vacuum-impregnated with anti-corrosion liquid. The anti-corrosion liquid is a mixture of furfuryl alcohol and ammonium borate, which has high toxicity. Formaldehyde resin adhesive, the basis of the preparation of the adhesive is formaldehyde solution, which contains a large amount of formaldehyde, which will cause great harm to the human body during the preparation and use of plywood
