Problems solved by technology

With the advancement of science and technology, the connection between different parts of the world is getting closer and closer. Domestically produced wooden furniture sells well all over the world. At the same time, it also brings technical problems to the wooden furniture industry: due to the large temperature difference between different regions on the earth, the humidity No, the frame wood of wooden furniture is very easy to crack and deform, thus destroying the appearance of wooden furniture and bringing great troubles to wooden furniture enterprises and consumers
[0007] At present, in order to reduce the cracking and deformation of wooden combs, the usual practice is to paint the surface of wood products to reduce the impact of external humidity on wood products. The post-treatment layer will be worn away. In addition, the lacquer will change the natural color of the wood itself, making the wooden comb lack of natural color. In addition, due to the influence of the paint itself and the self-expansion of the lacquer itself, the wood comb will be damaged. Paint on the surface still cannot reduce the influence of external humidity on wood products.
On the other hand, when traditional paint is used outdoors, it mainly forms a layer of paint film with strong physical and chemical properties on the surface of the wood to seal the wood surface, making the wood unable to breathe, and it is easy to crack and the paint film falls off after a long time; When irradiated, it is very easy to produce yellowing, and the weather resistance and durability are poor; at the same time, the raw materials of traditional paints and coatings are mostly chemical products, which contain a lot of toxic and irritating ingredients, which are harmful to the human body and cannot meet the current people's health and environmental protection requirements. requirements

Embodiment 1

[0029] A method for preventing cracking of wood, comprising the following steps:

[0030] a. Log processing: first take the log that needs to be cracked, and dry it in the shade until the moisture content of the wood is lower than 60%, then cut the log into boards according to the required size, and the thickness of the board is 5cm; set aside.

[0031] b. Plate drying: take the plate described in step a, and dry it for 3 days with a reduced-pressure drying method to obtain a dried plate for future use; wherein, the parameters of the drying method are that the pressure is 2.67kpa, and the temperature is 30°C.

[0032] c. Anti-cracking treatment: Take the dry board described in step b, soak it with wood anti-cracking agent at a temperature of 25°C for 2 days, then take it out and place it in a pressurized environment for 10 hours, the pressurized pressure is 110kpa, and finally move it indoors and dry it in the shade To the desired moisture content, the board has to be treated....

Embodiment 2

[0036] A method for preventing cracking of wood, comprising the following steps:

[0037] a. Log processing: First take the log that needs to be cracked, dry it in the shade until the moisture content of the wood is lower than 60%, then cut the log into boards according to the required size, and the thickness of the board is 10cm; set aside.

[0038] b. Plate drying: take the plate described in step a, and dry it for 7 days by vacuum drying method to obtain a dry plate for future use; wherein, the parameters of the drying method are that the pressure is 60kpa, and the temperature is 60°C.

[0039] c. Anti-cracking treatment: Take the dry board described in step b, soak it with wood anti-cracking agent at a temperature of 40°C for 8 days, then take it out and place it in a pressurized environment for 36 hours, the pressurized pressure is 130kpa, and finally move it indoors and dry it in the shade To the desired moisture content, the board has to be treated.

Abstract

The invention relates to the technical field of wood processing, in particular to an anti-cracking method for woods. The anti-cracking method includes the steps: a, treating raw woods: firstly taking raw woods needing to prevent cracks, drying in the shade, and cutting the raw woods into plates; b, drying the plates: drying by the aid of a pressure reducing and drying method to obtain the dried plates; c, performing anti-cracking treatment: soaking the dried plates by the aid of wood anti-cracking agents, taking out and placing for 10-36h under the pressurized environments, moving the plates into a room, and drying in the shade; d, preparing wood finished products: preparing the wood finished products according to needs, painting the wood anti-cracking agents on the surfaces of the wood finished products for 1-5 times, and drying in the shade to obtain anti-cracking woods. The anti-cracking method has the advantages that the method is green and environmentally friendly, the treated woods are good in anti-cracking effect and durability, and cracking rate of the treated woods is reduced. The whole production process is controllable and nontoxic, and the anti-cracking method is applicable to batch operation of factories.
