[0002] Wood is a common material in construction and decoration in my country. It has the advantages of being natural, environmentally friendly, beautiful, and maintaining space humidity balance. However, wood is an organic anisotropic material, which is prone to deformation, cracking, water absorption, mold, and insects during use. and other defects; now, with the use of wood more and more widely, wood softening and mildew prevention methods are also emerging, but the current wood softening and mildew prevention methods are carried out separately, the process is more complicated, and the process used The treatment liquid contains a variety of harmful chemical components, which will pollute the environment and endanger human health during the preparation and use of wood products

Embodiment 1

[0023] A method for softening and preventing mildew of wood, comprising the following steps:

[0024] (1) Timber finishing: peel off the bark of the wood, cut it according to the required length and width, and get the wood blank;

[0025] (2) Wood acid soaking: put the wood blank in a boiled acetic acid solution with a volume fraction of 1.2%, and soak it at 75~80°C for 9 hours, which can promote the entry of water into the wood fiber, reduce the pH of the wood, and accelerate the softening of the wood fiber. Cool down to 30~35°C, ferment to get sour foam wood;

[0026] (3) Alkaline cleaning of wood: Put the acid-foamed wood in the treatment room, spray the edible alkali solution with a mass concentration of 1.6% evenly on the acid-foamed wood, spray repeatedly 5 times, neutralize the residual acetic acid in the wood, and carry out after spraying. Freezing and thawing can make the water change into crystal water repeatedly, increase the intercellular space of wood, improve th...

Embodiment 2

[0040] A method for softening and preventing mildew of wood, comprising the following steps:

[0041] (1) Timber finishing: peel off the bark of the wood, cut it according to the required length and width, and get the wood blank;

[0042] (2) Wood acid soaking: put the wood blank in a boiled acetic acid solution with a volume fraction of 1.3%, and soak it at 75~80°C for 9 hours, which can promote the entry of water into the wood fiber, reduce the pH of the wood, and accelerate the softening of the wood fiber. Cool down to 30~35°C, ferment to get sour foam wood;

[0043] (3) Alkaline cleaning of wood: Put the acid-foamed wood in the treatment room, spray the edible alkali solution with a mass concentration of 1.7% evenly on the acid-foamed wood, spray repeatedly 5 times, neutralize the residual acetic acid in the wood, and carry out after spraying. Freezing and thawing can make the water change into crystal water repeatedly, increase the intercellular space of wood, improve th...

Embodiment 3

[0057] A method for softening and preventing mildew of wood, comprising the following steps:

[0058] (1) Timber finishing: peel off the bark of the wood, cut it according to the required length and width, and get the wood blank;

[0059] (2) Wood acid soaking: put the wood blank in a boiled acetic acid solution with a volume fraction of 1.4%, and soak it at 75~80°C for 10 hours, which can promote the entry of water into the wood fiber, reduce the pH of the wood, and accelerate the softening of the wood fiber. Cool down to 30~35°C, ferment to get sour foam wood;

[0060] (3) Alkaline cleaning of wood: put the acid-foamed wood in the treatment room, spray the edible alkali solution with a mass concentration of 1.8% evenly on the acid-foamed wood, spray repeatedly 5 times, neutralize the residual acetic acid in the wood, and carry out after spraying. Freezing and thawing can make the water change into crystal water repeatedly, increase the intercellular space of wood, improve t...

Abstract

The invention mainly relates to the technical field of wooden product processing, and discloses a wood softening and mouldproof method. The method comprises the following steps: arranging wood; soaking the wood in acid; washing the wood with alkaline; blanching the wood; and softening the wood. The method is simple, and convenient to operate; mass treatment can be carried out; the pliability of the wood can be improved; breaking and cracking phenomena occurring during use can be reduced, the breaking rate is decreased to be 2.7%, and the cracking rate is decreased to be 4.9%; the mouldproof time is prolonged, so that the use performance of the wood is obviously improved, and as a result, the economic income is increased by 9.6%; after being cut, the wood is soaked in an acetate solution which contains high-concentration white granulated sugar, so that water entering the wood fibers can be accelerated to decrease the pH of the wood, and as a result, the wood fibers can be quickly softened; then angel wine active dry yeast is added for fermentation, and the generated ethyl acohol and bioactive constituents can permeate the wood fibers; after drying, pore structures among the fibers can be increased, thus the pliability of the wood can be improved; the color of the wood can be prevented from being deepened; and treatment traces are reduced.
