Description

The invention relates to the field of decorative art and can be used for artistic painting of wood products in folk crafts, as well as for artistic painting of hunting rifle butts.

A known method of manufacturing art wood products according to patent RU 2049101. The invention: the surface of the workpiece wood products are primed with a composition comprising, kg: starch - 0.1-0.15, water - 1.29-1.31, or composition, including, kg: starch - 0.1-0.15, water - 1.29-1.31, 50% aqueous polyvinyl acetate dispersion - 0.11-1.12, dibutyl phthalate or dibutyl sebacinate - 0.008-0.01. Then the surface is ground, the product is painted and artistic painting is carried out with aqueous solutions of organic dyes, gouache, water-based emulsion or tempera paints, varnished with alkyd pentaphthalic varnish, and the product is inter-operative and final dried at a temperature of 18-25 ° C.

The disadvantages of the known technical solutions are:

- reduced durability of the decorative coating, because the starch and water contained in the soil form a starch paste, which, after drying, is unstable to the effects of molds and atmospheric moisture on it, in addition, starch paste exhibits reduced adhesive ability;

- the complexity of the process, which involves first dyeing the product, and then art painting.

A known method of manufacturing artistic and decorative wood products according to patent RU 2156783, adopted as a prototype. The known method includes repeated priming of the surface of the product, grinding, painting, art painting, varnishing, interoperational and final drying, while priming is carried out with the composition in the following ratio of ingredients, masses. hours: dibutyl phthalate or dibutyl sebationate - 0.002-0.015, 50% aqueous polyvinyl acetate dispersion - 0.04-0.1, starch - 0.1-0.18, water - to working viscosity.

The prototype method determines the use of covering dyes for coloring and painting wood products. This is a disadvantage of the prototype, because covering dyes hide the natural texture of wood, which causes the fragmentation of the composition of the picture and erodes the integrity of its aesthetic perception. Other disadvantages of the prototype are: the complexity of the process, a significant amount of ingredients for its implementation, increased complexity and cost of the finished product.

The objective and technical result of the proposed invention are:

- ensuring the visibility on the finished product of the natural texture of wood;

- simplification of the process;

- reducing the complexity of the process;

- reduction in the cost of the finished product.

The technical result is achieved by the fact that in the method of manufacturing an artistic and decorative wood product, including grinding the surface of the product, painting, art painting, varnishing, interoperational drying, according to the invention, painting and art painting are carried out in a single operation with a transparent dye by sequentially applying tones from the light dye palette to dark, while the content of the components of the dye is, mass. %:

water soluble stain 10-50 polyvinyl acetate glue 29-31 water rest

To obtain a very dark tone, the palette uses a clean stain without adding glue and water to it.

They wet the surfaces with the natural color of the wood, located between the areas covered with different tones of the dye, the composition containing, mass. %:

polyvinyl acetate glue 29-31 water rest

After staining and artistic painting of the product, a protective coating with a transparent pound of the Sayerlack TU-3 brand is applied to its surface.

Varnishing of the product is carried out with matt polyurethane varnish of the Sayerlack TZ-36 brand.

The dye contains stains of grades TY 001 / T 01-T20.

As the polyvinyl acetate adhesive used for solid wood brand Kleiberit 304.

Coloring and painting wood products with a transparent stain-based dye with successive application of tones from a light to dark dye palette tones provides the visibility of the natural wood texture on the finished product, and the protective coating on the product with transparent soil and varnishing with matt varnish ensures visibility as a natural wood texture, and all elements of art painting. This allows you to make wood products with a decor that provides the effect of the integrity of the composition of the picture, and increases the aesthetics of the product.

Performing dyeing and artistic painting of the product in one operation with a transparent dye by successively applying tones of the dye palette from light to dark allows us to simplify the process, reduce its complexity and cost of the finished product.

The composition and quantitative content of the components of the dye is determined empirically, based on the conditions for the preparation of the tone palette of the dye containing at least four tones. The obtained properties of a transparent dye should provide the ability to control the spreading of the dye on the substrate, while maintaining the remaining properties of the dye, i.e. to ensure the visibility of both the natural texture of the tree, and all elements of art painting.

Adding less than 10% stain to the dye solution does not provide a difference in tone from the natural color of the wood.

Adding more than 50% stain to the dye solution is impractical due to the very dark tone of the palette.

Adding less than 29% of the glue to the solution does not provide the necessary viscosity of the dye and control the spreading of the dye on the substrate.

Adding more than 31% of the glue to the dye solution gives the dye an excessive viscosity, which makes the smears voluminous, the tone is cloudy, covers the natural texture of the wood.

During the creation of the experimental sample, it was revealed that the composition containing, mass. %: polyvinyl acetate glue 29-31; water - the rest, can be used as a wetting solution for clean stains, filling the pores and fibers of wood. It forms a colorless, thin, even, transparent film. A pure stain is able to spread uncontrollably only along the fibers, when the fibers are covered with a colorless composition, then a clean stain can be painted, deepening the shadows and enhancing the contrast.

To specify the tint palette of the dye based on the stain, the applicant conducted laboratory studies. For this were taken:

- wooden backing - birch plywood;

- stain brand TY 001 / T04 - color blue;

- binder - polyvinyl acetate adhesive brand "Kleiberit 304.1";

- solvent - water;

- a brush made of synthetic fiber.

As a result of a series of experiments and their analysis, the compositions of a transparent dye were determined for several optimal tones used in the artistic painting of wood. The results are shown in the table below.

For a clearer understanding of the invention, the accompanying drawings depict experimental examples of the use of transparent dye tone palettes on beech and ash substrates with a visible natural wood texture.

In FIG. 1 shows five experimental samples of the tone palette in accordance with paragraphs. 1-5 tables of a transparent dye on a substrate made of beech wood with a visible natural wood texture (wood stain TY-M 001 / T04 - blue is used).

In FIG. 2 shows four experimental samples of the tone palette in accordance with paragraphs. 2-5 tables of a transparent dye on a substrate of ash veneer with a visible natural wood texture (wood stain TY-M 001 / T04 - blue).

In FIG. Figure 3 shows a sample of the beginning of the process of painting and art painting of a gun butt.

In FIG. Figure 4 shows an experimental sample of artistic painting imitating woodcarving on a birch plywood substrate using a transparent dye based on stain of the brand TY 001 / T20 - a light nut with a visible natural wood texture.

In FIG. Figure 5 shows a prototype of a painted and painted gun stock using a transparent dye based on a stain of the brand TY 001 / T20-light nut with a visible natural wood texture.

Based on the above experimental data, the applicant proposed the following method of manufacturing an artistic and decorative wood product using a transparent stain based on stain.

1. Grind the surface of the workpiece from dry wood.

2. On the polished surface, the contours of the drawing are applied, for example, with a pencil.

3. Dyeing and art painting is carried out in one operation with a transparent dye by successively applying tones of the dye palette from light to dark.

4. Tone 2 (light) with a brush covers all areas of the picture, except those that are conventionally considered white (the natural color of the tree).

5. Tone 3 (saturated) covers the areas of the picture of the middle tone.

6. The tone 4 (dark) give volume to the picture and indicate shadows and partial shade.

7. In tone 5 (very dark, that is, a clean stain) deepen the shadows.

8. Tone 1 (colorless) is used to wet surfaces with a natural color of wood located between product areas coated with different tones of dye to achieve a smooth transition between these areas.

9. Dry the product.

10. Apply a transparent protective coating to the product.

11. Dry the product.

12. Finish grinding the product.

13. Varnish the product with matte varnish.

14. Dry the product.

The essence of the method is illustrated by examples of specific performance.

water soluble stain fifty polyvinyl acetate glue 29th water rest

To obtain a very dark tone of a transparent dye (tones according to paragraph 5 of the table), a stain of the brand ΤΥ 001 / T20 of the color light nut was taken for 100 mass. %

Staining and artistic painting were carried out in one operation with a transparent dye by successively applying tones of the dye palette from light to dark. To do this, tone 2 (light) with a brush covered all areas of the picture, except those that are conventionally considered white, leaving the natural color of the tree. Tone 3 (saturated) covered areas of the picture of the middle tone. Tone 4 (dark) gave volume to the picture and indicated shadows and penumbra. In tone 5 (very dark, i.e. with a clean stain), the shadows were deepened.

Tone 1 (colorless according to paragraph 1 of the table) was used to wet surfaces with the natural color of wood located between product areas coated with different tones of the dye, and a smooth transition between these areas was obtained.

Then the product was dried, a transparent protective coating was applied to the product. The product was dried again, then fine grinding, varnishing of the product with matte varnish, and final drying of the product. On the butt of the gun, a drawing was obtained (see Fig. 5), on which the natural iridescent moire texture of the walnut tree is clearly visible.

The proposed method allowed us to simplify the technological process of art painting, reduce the complexity and cost of finished art products.
