Insect-proof multi-layer eucalyptus wood board and production method thereof

Abstract

The invention provides an insect-proof multi-layer eucalyptus wood board and a production method thereof. The production method of the multi-layer board comprises the steps of single plate thin platesorting, thin plate glue applying, cold pressing, hot pressing, standing curing, dust scraping, sanding, repair, trimming and plate pasting, and is characterized in that a layer of insect-proof curedfilm is sprayed at the peripheral surface, the upper surface and the lower surface of a slab before first hot pressing and final hot pressing to prevents glue from being dried too quickly during the hot pressing process and maintain stress inside the multi-layer board, the urea-formaldehyde glue can be fully reacted completely, the formed multi-layer board is not prone to mildewing, in the use process of a user, volatile formaldehyde is also reduced, and after hot pressing, the board is subjected to standing curing, sanding and plate pasting, so that the insect-proof multi-layer eucalyptus wood board product can be obtained by edge sawing and packaging.

Description

technical field [0001] The invention relates to a multilayer wood board and a production method thereof, in particular to an insect-proof multilayer eucalyptus wood board and a production method thereof. Background technique [0002] Multi-layer wood board is a multi-layer board-like material made of wood sections that are peeled into veneers or sliced ​​into thin wood, and then glued with adhesives. Usually, the fiber directions of adjacent layers of veneers are glued perpendicular to each other. It is made, and the outside is veneered or not veneered according to needs, also known as glued multilayer board. [0003] Multi-layer wood board is one of the commonly used materials for furniture, and it is one of the three major boards of wood-based panels. It can also be used for aircraft, ships, trains, automobiles, buildings and packaging boxes. Usually its surface board and inner board are arranged symmetrically on both sides of the central layer or board core. The slab ma...

Problems solved by technology

[0017] In the process of product production and application, the applicant has thought of many technical solutions in the composite urea-formaldehyde resin adhesive, such as adding insect-proof and mildew-proof agents, flame retardants, preservatives, high-temperature resistant agents, etc., but also overcomes existing problems. Many urea-formaldehyde resin adhesives have the disadvantage of releasing more formaldehyde, but there are still disadvantages in some aspects. For example, during the hot pressing process, sometimes the product is easily deformed when the pressure is not uniform enough, and sometimes the drying process is not uniform enough, resulting in cracking. , some sizing is uneven, and there is no guarantee that the formaldehyde of the product exceeds the standard, and many technical indicators still need to be improved
