Multi-layer board integral hot pressing process

Abstract

The invention relates to the technical field of wood processing, in particular to a multi-layer board integral hot pressing process. The method comprises the following steps that firstly, repeatedly spraying and airing is carried out on a wood board so that the water absorption expansion rate of the wood board can be effectively reduced, then the wood board can be effectively prevented from beingprone to absorb water and damaged after being made into a drawing board, and the ageing resistance of the board is enhanced; then the wood board is placed into an anti-corrosion liquid, so that the anti-corrosion effect of the wood board is enhanced, then the moisture content of the wood board is reduced through hot air circulation drying, and therefore the inner temperature and the outer temperature of the wood board are uniform and consistent, the moisture content of the wood board is reduced, and the firmness of the wood board is improved; and finally, the wood board is subjected to coronatreatment, so that the static property of the wood board is enhanced, the adhesion of the subsequent wood board is better, then the wood board is bonded through an adhesive, hot pressing and freezingtreatment are carried out, and then the prepared multi-layer board is good in bonding effect and high in firmness.

Description

Technical field:

[0001] The invention relates to the technical field of drawing board processing, in particular to an integral hot pressing process of a multilayer board. Background technique:

[0002] The drawing board is an indispensable tool for fixing the frame of art and calligraphy. When sketching and painting, it is often used to pad the tablet with drawing paper, and it is often placed on the drawing board. The drawing boards are mostly made of wood, and the wooden drawing boards have good texture and high artistic sense. Among them: solid wood boards are expensive, and are not conducive to environmental protection, and are difficult to promote in large quantities; MDF, particleboard, sandwich boards, etc. are relatively cheap, but their performance is much worse than that of solid wood. To balance the above factors, the current imitation solid wood process is adopted, such as the edge sealing process of multi-layer boards, the net material is opened after the multi-lay...
