Preparation method of anti-cracking high-strength board materials

Abstract

The invention discloses a preparation method of anti-cracking high-strength board materials. The preparation method comprises the following steps of carrying out screening, splicing, cleaning, drying,coping, dipping, painting and airing, removing logs with seriously warped processing parts and rotten in a large area, carrying out double-sided thicknessing on woods, longitudinally sawing solid woods, splicing a plurality of board materials, and cleaning the spliced board materials; putting the board materials into a drying machine, drying for more than 24 hours at the temperature of 40 DEG C-60 DEG C, grinding recesses and bulges on the surfaces of the board materials through a belt sander to enable the surfaces of the board materials to be smooth and burr-free, and soaking the board materials in a 30% polyethylene glycol solution for more than 2 hours; and spraying ultraviolet curing paint on the surfaces of the wood boards through mechanical spraying, enabling spraying to be uniform,and carrying out supplementary spraying manually on uneven parts. According to the preparation method, various improved procedures are adopted, the internal stress between the board materials is relieved, redundant moisture in the board materials is removed, the board materials are soaked in the polyethylene glycol solution, the possibility of surface cracking is reduced, and the surface qualityof the board materials is improved.

Description

technical field [0001] The invention belongs to the field of sheet material preparation, and in particular relates to a method for preparing a crack-resistant high-strength sheet material. Background technique [0002] Solid wood boards are wood boards made from whole logs. Solid wood boards are generally classified according to the name of the log material, and there is no uniform standard specification. Solid wood boards are relative to a large number of non-solid wood boards, such as plywood and pressed boards produced from wood processing waste, crop straw, chaff, peanut shells and other materials. [0003] Solid wood boards are sturdy and durable, with natural textures. Most of them have the unique aroma of natural wood. They have good hygroscopicity and air permeability. They are beneficial to human health and do not cause environmental pollution. They are high-quality boards for making high-end furniture and decorating houses. The solid wood boards of some special m...

AI Technical Summary

Problems solved by technology

The solid wood board itself is not wear-resistant, has a short service life, and is prone to aging, cracking, and deformation. The cracking of the solid wood board leads to waste of wood, and at the same time leads to poor aesthetics and consistency of furniture made of solid wood boards, which hinders the application of solid wood boards. It is urgent to design a preparation process for anti-cracking high-strength plates
