[Detailed description of the invention]

INDUSTRIAL APPLICATION FIELD The present invention relates to a method for processing wood materials. Prior Art Wood materials, especially wood, have many advantages such as a beautiful appearance, a warm texture, excellent workability, and easy availability.
Widely used for building materials, etc. In particular, wood products such as furniture and household appliances have many curved parts due to their design, such as corners of legs, backrests, armrests, and top plates, and curved corners of doors and window frames. Departments, etc. Conventional methods for obtaining products with such parts include () cutting with a knife, () plywood molding, () bending by heating and plasticizing wood, () bending by plasticizing wood with chemicals, etc. has been adopted. but,
The method () has the disadvantage that there is a large loss of wood, the cost is high, and anisotropy of wood strength appears in the bent shape. In addition, the method () has problems in terms of strength, adhesive cost, extensive molding equipment, relatively high processing costs, and is generally expensive, and there are limitations on the shapes that can be processed. The methods in () can be roughly divided into two groups: plasticizing wood by external heating such as steaming, boiling, and electric heating, and plasticizing wood by internal heating such as high frequency and microwave. In the former method, it takes a long time to fully plasticize the inside of the wood, and the bending process must be performed before the material temperature drops, resulting in a significant decrease in productivity and a long time. The disadvantage is that the wood tends to discolor due to heating. In addition, with the latter method, it is difficult to maintain the wood in a uniform heated state. Furthermore, in the case of high frequency, it is difficult to heat odd-numbered surfaces with plate heating, and in the case of microwaves, it is difficult to heat wood with a large cross-sectional area. When applied to a material, heating tends to be uneven, wrinkles and cuts are generally caused by buckling on the compression side, and cracks on the tension side tend to occur, resulting in a high defect rate. Furthermore, in the method (), chemicals such as ammonia, amines, caustic soda,
Sodium dichromate, sulfite, etc. were used, but the use of these chemicals may cause the wood to discolor.
There are various problems such as waste liquid treatment and contamination of the working environment, and there are costs and operational difficulties in mass production. Furthermore, in addition to the above-mentioned processing when using wood, decoration that takes advantage of the beautiful wood grain pattern cannot be overlooked, and is often used in the production of plywood. These are usually manufactured by cutting a veneer with a thickness of about 0.1 mm to 10 mm from raw wood, but cracks and cracks can occur due to various factors such as the tree species, place of origin, resin content, moisture content, etc. , which may cause deterioration in the quality of subsequent products. Particularly in the case of hardwood, there is a tendency for boiling to take several days to two weeks, which not only impairs productivity but also increases production costs. Means for Solving the Problems In view of the above points, the present inventor has conducted extensive research into plasticizing wood materials that exhibits a good appearance and can significantly reduce the defective rate during processing, and has found that surfactant It was discovered that the desired objective could be achieved by impregnating a wooden material with a chemical containing the same, and then deforming the wooden material or cutting the veneer according to conventional methods, and thus completed the present invention. I came to the conclusion. That is, the present invention provides a method for processing a wood material, which is characterized by impregnating the wood material with a chemical containing a surfactant to plasticize the material when processing the wood material, and a method for processing the wood material.

It is preferable to mix 100 parts (preferably 10 to 90 parts). When transforming the wood material that has been subjected to the above impregnation treatment, it is possible to carry out the transformation immediately after the impregnation treatment, but especially when the agent of the present invention is impregnated in the form of an aqueous solution, the moisture content suitable for the transformation treatment is Processing can be made easier by providing a moisture adjustment step so that the following is achieved. As for the method of deforming the impregnated material, the most suitable method can be selected arbitrarily from among the various methods conventionally used. In this case, by heating the impregnating material in advance, the effect of the impregnating treatment with the agent of the present invention can be more effectively exhibited. As the heating means, for example, electric heating, steaming, boiling, high frequency heating, and microwave heating can be used. Further, the heating step may be performed immediately before or simultaneously with the deformation process. There is no particular restriction on the deformation processing of the plasticized wood material, and examples thereof include uneven curved surface forming using a press, bent wood processing using a press and a male and female die, bent wood processing using a roller, and extrusion bending processing using an arc die. Particularly in the case of bent wood processing, the Tornet method, in which a thin steel plate is bent while being in close contact with the wood material, and its applied methods are exclusively used in practice.
Of course, these methods can also be used in the present invention. In the present invention, in order to permanently fix the deformation imparted to the wood material, it is desirable to transfer the processed material to a drying step following the deformation processing step and dry it to a moisture content of approximately 10%. When manufacturing veneers, it can be processed using almost the same process as conventional methods. For example, for tree species that do not require a boiling process, such as Kiri, Camphor, Shioji, Sen, Hinoki, Magashiro, and Lauan, the agent of the present invention can be pre-impregnated with the above-mentioned various impregnation methods, and then cut with a slicer. good. In addition, for tree species that require a boiling process such as zelkova, quince, ebony, oak, sapele, moabi, birch, and ash, it is of course possible to pre-impregnate them using the various impregnation methods described above, but it is best to soak them in boiling water. Simply adding the agent of the present invention is sufficiently effective, and the boiling period can be shortened to 1/2 to 1/4. Effects of the Invention The method of the present invention has the following advantages regarding the deformation of wood materials and the production of veneers. () Because plasticization of the wood material due to overheating occurs more quickly than in the case of conventional methods, long-term heat treatment is not required, workability is improved, and discoloration of the material can be prevented. () Compared to untreated materials, it can be deformed, cut, etc. with a small amount of force, does not require powerful equipment, and wear and tear on cutlery etc. is reduced. () Cracks and wrinkles are less likely to occur during deformation processing, reducing the defective rate. In addition, there is no need to distinguish between straight grain, board grain, etc., and wood species that could not be used in the past can be used, making it possible to use wood more effectively and reduce costs. () Very little recovery of shape after deformation processing. () Compared to methods using other plasticizers, such as ammonia, amines, caustic soda, sodium dichromate, sulfites, etc., it is safer, reduces environmental pollution, and discolors due to drug contamination of the material. does not occur. () Compared to conventional methods, deformation processing is possible with a relatively low moisture content, so post-processing such as drying can be simplified and productivity can be improved. () It is possible to easily obtain a high-quality veneer without back cracks, cracks, reverse grains, fuzzing, grain spills, etc. () In particular, diols combine with cellulose in wood materials, which suppresses dimensional changes due to moisture absorption and desorption of the material, making it possible to reduce product distortion. Due to the various advantages described above, the present invention can improve the appearance of materials such as plywood and veneer, woodwork products such as furniture, household appliances, and crafts, and building materials such as window frames, door frames, and decorative boards. high-quality processed products with a relatively low cost,
