Description
Technical Field
The invention relates to a preparation method for preventing wood from cracking and deforming.
Background
Compared with furniture made of metal, plastic and other materials, the furniture made of wood has the advantages of beautiful and natural appearance, comfortable contact with human body and the like. However, wood also has its own drawbacks, namely being susceptible to contamination, being susceptible to mould, being possibly deformed, etc.
In order to overcome the above technical problems, in the prior art, a wax injection mode is adopted, i.e. wax is injected into wood. For example: CN201711080591.8 discloses a wax wood furniture board production method, which comprises the following steps: step one, selecting mature rosewood as a wood raw material, and air-drying for 20-30 days; step two, cutting the wood raw material into a required shape; step three, balancing the moisture of the wood raw material for 10 days; pouring a proper amount of synthetic wax into a wax injection container, controlling the temperature of the synthetic wax to be between 90 and 100 ℃, and keeping the temperature constant until the synthetic wax is melted into a liquid state; placing the wood raw materials in a wax injection container in a side-standing manner, controlling the temperature of wax liquid between 100 ℃ and 120 ℃ and injecting wax; step six, closing the energy source of the wax injection container, naturally cooling the wax injection container, and waiting for 5-7 hours to fix and mold the wax injection container; and step seven, polishing the formed wax wood board, packaging and storing.
However, the existing method has the following defects: 1. the wax injection steps are numerous. 2. Although waterproof and corrosion-resistant, it does not indicate whether cracking and deformation problems can be controlled.
Disclosure of Invention
The invention provides a preparation method for preventing wood from cracking and deforming, which overcomes the defects of the preparation method of solid wood furniture in the background technology.
The technical scheme adopted by the invention for solving the technical problem is as follows:
a preparation method for preventing wood from cracking and deforming comprises the following steps:
1) drying the cut wood to water content of 10-20%;
2) after the wax is melted, putting the wood into a sealable container, and adjusting the heating temperature in the container to ensure that the wax temperature is adjusted to 135-145 ℃;
3) according to different wood species densities, the conventional density wood is 18-36 hours, and the high density wood is 60-128 hours;
4) the temperature of the wax is adjusted to 155-165 ℃ 1 hour before discharging; after the wax injection time is up, the air pressure in the container is recovered to be normal; taking out the wood after the temperature of the wood after wax injection is reduced to normal temperature;
preferably, the cut wood is dried to a moisture content of 12-16%.
In the present invention, the wax species described in step 2) mainly refers to biological wax (the homemade biological wax is prepared by the following method: putting the honeycomb into water with the material-liquid ratio of 1:0.2-1, boiling with slow fire until the water is boiled, keeping the water temperature at 90-100 ℃, continuously stirring for 6-8h, filtering to remove filter residue, and solidifying to obtain the homemade biological wax).
In addition to beeswax, the biological wax of the present invention may further include at least one of insect wax, shellac wax, spermaceti wax, and wool wax.
In the present invention, the conventional density wood is a wood having an air-dry density of less than 0.76g/cm3 when the wood has a water content of 12%, and its species such as cherry, mahogany, red oak; the high-density wood is wood with air-dry density of more than 0.76g/cm3 when the water content of the wood is 12%, such as redwood.
Compared with the background technology, the technical scheme has the following advantages:
1. the wood is sealed by the wood fiber conduit from inside to outside after wax injection, so that the problem of mildew generation caused by mildew breeding in the wood is solved.
2. The wax permeates into the wood fiber conduit through high temperature (135-.
