Embodiment 1

[0013] A processing method of birch bark, using the following steps to process:

[0014] (1) Peel off the fresh birch bark, clean the surface, use a steamer to fumigate for 2 hours, and then cool naturally;

[0015] (2) Prepare the treatment solution by mixing 3.8 parts of polyethylene glycol, 7 parts of glycerin, 4.8 parts of potassium nitrate, 1.6 parts of pine nut oil, 2 parts of chlorinated paraffin, and 25 parts of water by weight to prepare the treatment solution;

[0016] (3) Put the white birch bark treated in step (1) into the treatment solution prepared in step (2) and soak for 2-3 days. After the treatment is completed, rinse it with clean water, and then use a steamer to fumigate for 0.5h. Take it out, cool down, and cool down at a rate of 2°C / min until normal temperature, then flatten.

Embodiment 2

[0018] The treatment solution is prepared by weight from 3.5 parts of polyethylene glycol, 7 parts of glycerin, 5.2 parts of potassium nitrate, 1.2 parts of pine nut oil, 2 parts of chlorinated paraffin, and 25 parts of water.

Embodiment 3

[0020] The treatment solution is prepared by weight from 3.2 parts of polyethylene glycol, 6 parts of glycerin, 6 parts of potassium nitrate, 1.5 parts of pine nut oil, 1.5 parts of chlorinated paraffin, and 25 parts of water.

[0021] Use the treatment method of the embodiment of the present invention to process white birch bark, the flexibility of the white birch bark after treatment is enhanced, the color of the white birch bark after treatment is stable, and through fumigation treatment, carry out slow cooling treatment, can improve the resistance of white birch bark The ability of temperature change, and easy to color, it will not fall off after coloring, and the product will not crack or fade after being treated for 70 hours at a temperature of 80 ° C and a relative humidity of 18%. However, direct treatment with glycerin aqueous solution or alcohol solution is not only difficult to color, but also the product will be deformed and faded to varying degrees when the product...

Abstract

The invention relates to a method for treating birch bark. The method comprises the following steps: (1) peeling fresh birch bark, cleaning the surface, suffocating for 1.5-2 hours by a steamer, and then cooling naturally; (2) preparing a treatment solution, mixing 3.2-4 parts of polyethylene glycol, 6-8 parts of glycerinum, 4.5-6.8 parts of potassium nitrate, 1-1.8 parts of pine-seed oil, 1.5-2.4 parts of chlorinated paraffin and 25 parts of water evenly so as to prepare the treatment solution; (3) putting birch bark treated in the step (1) into the treatment solution prepared in the step (2), soaking for 2-3 days, flushing clean with clear water after treating is completed, then suffocating for 0.5 hour by the steamer, taking out, cooling to normal temperature at the cooling speed of 2 DEG C / min. The method for treating birch bark for bark pictures is simple, and is convenient to use; the treated birch bark is good in stability and is easy to color.

Description

technical field [0001] The invention belongs to the field of wood treatment, and in particular relates to a treatment method for birch bark. Background technique [0002] Bark painting is a variety of semi-relief pictures that use the natural shape, different colors and textures of bark, creatively and cleverly combined and pasted, that is, bark painting, mainly landscape paintings. Painting on bark paper, the pigments are mainly mineral and plant pigments, and the content is mainly portraits or life scenes. The other is ancient Egyptian art, bark paper is spread out with the fibers of bark and pressed with huge stones. Bark painting is now extremely popular in the art market. When processing bark painting, the bark needs to be treated to prevent deformation and cracking of the bark, which will affect the value of the bark painting. Birch bark is an important raw material for bark painting. Its bark has good toughness and orange-yellow inner bark, which is very suitable fo...
