Example Embodiment

[0025] The specific implementation manners for realizing the wood water blocking and shrinking and swelling prevention of the present invention are:

[0026] The wood water-blocking and anti-swelling treatment method of the present invention is divided into two steps:

[0027] 1. Selection and preparation of raw materials for treatment liquid

[0028] The raw materials of the technical material water blocking and anti-swelling treatment liquid are prepared according to the following formula ratio (weight%):

[0029] Polyethylene glycol 50;

[0030] Methyl methacrylate 8;

[0031] Ethanol 10;

[0032] Distilled water 32.

[0033] When preparing the treatment solution, heat and melt the polyethylene glycol first, then mix the polyethylene glycol, methyl methacrylate, ethanol, and distilled water in proportions, and stir to form a treatment solution with a uniform concentration.

[0034] 2. The treatment process of wood water blocking and shrinking and swelling is:

[0035] Put the w...

Abstract

The present invention provides waterproof and swelling and shrinking preventing timber treating method, and the method is treating timber with waterproof and swelling and shrinking preventing timber treating solution. The timber treating solution consists of fatty dihydric alcohol or its polymer 10-70 wt%, alkyl acrylate 5-10 wt%, alcohol 5-10 wt%, and distilled water 10-80 wt%. The treating process includes soaking timber or timber product in the timber treating solution inside a sealed treating tank under the pressure one -0.1 to 0.5 MPa, pressurizing and heating for soaking treatment, and final drying treatment. Thus treated timber sample has shrinkage resisting coefficient up to 70 % and moisture absorption resisting coefficient up to 60 %, so that the present invention can prevent deformation and cracking of timber product and raise the size stability of timber product effectively.

Description

Technical field [0001] The invention relates to a treatment method for wood, in particular to a treatment method for water resistance and shrinkage prevention of wood. Background technique [0002] As we all know, the moisture content of wood changes with the change of ambient temperature and humidity, which will cause the wood to swell and shrink, and the resulting stress changes will lead to wood deformation and cracking. In order to suppress its deformation speed and ensure that the solid wood products are stable in size and not deformed during production and use, before the wood is made into a solid wood product, the wood needs to be dried to a moisture content that is suitable for the environment in which the product is used, and then the solid wood product is produced. In the later stage, the outer surface of solid wood products is repeatedly waxed or sprayed with paint, paint and other substances to form a protective film on the outer surface to slow down the diffusio...
