Description

The invention relates to the field of arts and crafts, and more particularly to methods for manufacturing decorative wall products, and can be used to make various paintings, decorative panels, etc.

A known method of making mosaic type paintings using beads, according to which the initial image is divided into elements whose sizes correspond to the size of the beads, compare digital information about the hue and brightness of each of these elements and information about the hue and brightness of each of the beads, replace digital information for each of the elements with a color code, simultaneously with the separation of beads according to color codes, place them in accordance with the specified order for each of the elements of the initial images and sinter on a glass plate. This method is fully automated and does not require special skills from the contractor, but it requires the use of special expensive equipment, including software (EP 0829378, B44C 1/28, publ. 08.09.97).

The disadvantage of this method is that the finished product does not have high resistance to environmental influences, looks good at a distance, but upon closer examination, the bead structure of smear construction is manifested. In addition, with such a technique for designing the original image, it is impossible to perform fine work on decorating lines or small fragments.

There are quite a few different ways to design a primary image.

For example, a known method of manufacturing mosaic paintings, which consists in applying colored balls of mosaic on the surface of the product. Each color is applied simultaneously to the entire surface of the product using a stencil. The stencil is made by a computer-controlled laser in accordance with the pattern created on the screen. The area of the stencil corresponding to the area of the picture painted in a certain color is a lattice, the frequency of the holes of which depends on the diameter of the mosaic balls, the need for mutual fit. The size of the holes is less than the diameter of the balls. Balls of the corresponding color are first attached to the surface of the stencil, and then applied to the surface of the product. The flexibility of changing images is achieved due to the high speed of restoration of the stencils by immersing them in a composition that fills the holes cut out by the laser beam and hardens, forming a non-heat-resistant film that can quickly evaporate under the beam of a laser or other heat source when applying another pattern (RU 93013237, B44C 1/28 , published on September 10, 1995). This decision was made as a prototype.

The disadvantage of this solution is the difficulty of its application due to the need to use a laser to prepare a complex lattice template in design and to attach balls to the image. This method can be used in industrial production or in mass production of similar products.

The present invention is aimed at achieving a technical result, which consists in simplifying the manufacture of a decorated panel and making it possible to draw fine details on it.

The specified technical result is achieved by the fact that in the method of manufacturing a decorative panel, which consists in using a flat base with the original image, making patterns for at least part of the fragments in the original image with cutouts or cuts in the shape of the fragment, placing these patterns on top of the corresponding fragments on the original image and fixing on the original image in the cutouts or slots of the patterns of small friable elements of artificial or natural origin, with this specified friable elements for each slot of each template is used in a color corresponding to the color of the image fragment in the corresponding cutout or slot, after applying each template on top of its corresponding cutout or slot fragments in the original image, glue is poured into the specified cutout or slot to form an adhesive layer with a thickness, equal to the thickness of the template, along the walls of the cutout or slot, or a thickness exceeding the thickness of the template, while the specified small crumb is applied to the specified adhesive layer f elements, are fixed on top of this layer or Retractable in this layer.

These features are significant and are interconnected with the formation of a stable set of essential features sufficient to obtain the desired technical result.

The present invention is illustrated by a specific example of execution, which, however, is not the only possible, but clearly demonstrates the possibility of achieving the desired technical result.

Figure 1 - decorative panel made by the method according to the invention;

figure 2 is a fragment of the panel of figure 1 (enlarged);

figure 3 - the first stage of the manufacture of panels - overlay stencil;

figure 4 - the second stage of the manufacture of panels - pouring glue and applying to the adhesive layer of decorative elements;

figure 5 - the third stage of the manufacture of panels - the removal of the stencil with excess glue and decorative elements.

According to the present invention, a new method for decorating images deposited on a flat base is contemplated.

This method of manufacturing a decorative panel (Fig. 1) consists in using a flat base with the original image 1. For this image, templates 2 are made for at least part of the fragments in the original image. Templates are plates (paper, polymer film or other examples of flat plates made of any material) in which cutouts 3 or cuts are made according to the shape of the fragment to be decorated. Each of these patterns is stacked on top of the corresponding fragment in the original image (figure 2).

After applying each template over the corresponding cutout or slot in the original image (Fig. 3), glue (adhesive composition, polymer mass with the function of hardening under the influence of ambient temperature, or ultraviolet light, or heating) is poured into the specified cutout or slot to form an adhesive or a curable layer 4. The thickness of this layer is equal to the thickness of the template along the walls of the cut or slot or exceeds the thickness of the template. This is necessary for the formation of relief in the image (figure 2, where position 5 - relief projections) and in order to apply small friable elements 6 to this layer (figure 4), fixed on top of this layer, or recessed into this layer, or sprayed onto this layer. Thus, relief projections with a painted surface appear on the original image (Fig. 5).

Small friable elements can be of artificial or natural origin, while these friable elements for each slot of each template are used in a color corresponding to the color of the image fragment in the corresponding cut or slot. Glitter (finely chopped, metallized polyethylene terephthalate film of various colors with a particle shape in the form of a hexagon, with a particle size of 0.1 to 4.0 mm, polyester film glitters are excellent resistance to water, solvents, ultraviolet radiation), or rhinestones, or beads, or beads, or stones, or stone chips, or broken glass, or mixtures thereof. Small friable elements can be in granular form, in the form of crumbs or in powder form (in this case, the powder is sprayed onto the adhesive layer). As small friable elements, you can use elements with reflective properties.

As a mosaic material, faceted crystals (rhinestones) of crystal or glass with a flat bottom, with a reflective material deposited on the bottom (silver, gold or metal) can be used. Crystal sizes range from 1.7 to 11.9 mm in the metric system or from ss5 to ss50 in the Stones Size system. Crystals have a special facet of 14 or more faces.

A variant of the following technology for the manufacture of decorative coatings is possible. For a picture (image on canvas), a set of clichés or templates is made, each of which is prepared in size for at least part of the image area and is intended for the use of small particles of the same color. Then, in turn, each cliche is superimposed on the image, and glue is applied to this image, then the glued areas are sprinkled with glitters or rhinestones, or beads, or beads, or stones, etc. one color. A separate cliche (template) is made for each color.

As an adhesive or adhesive composition, you can use zapon varnish (NTs-218) with pre-drying for 30 minutes (final hardening within 12 hours), alkyd-based varnish (PF-283).

For strong attachment of small elements to the base, you can use a two-component adhesive based on acrylic. The binder and the fixer are mixed in a small amount, then the prepared adhesive mixture is applied to the slots of the template. Using a special wax stick or tweezers, transfer the crystals to the adhesive layer, pressing with a little effort. The color and size of the crystals are selected based on the pattern. In this way, the entire cutout of the template is filled, the adhesive composition is allowed to set, and then the template is removed. Allow the glue to harden for about 12 hours at room temperature. The choice of glue, or glue composition, or varnish, or other crystallizable polymer composition and their application depends on the structure of the material of the original image.

A method of manufacturing a decorative panel with pronounced picturesqueness allows to increase the strength of the product and, despite the manual nature of the manufacture, reduces the complexity of its manufacture. This panel can be made for use in outdoor advertising or for decorating buildings, since the material used for decorating belongs (for the most part) to the category of high resistance to aggressive environmental influences.

The proposed method is quite feasible, because the materials required for the manufacture are readily available, and the proposed technology makes it possible to facilitate the manual labor, which is most appreciated in the manufacture of decorative and applied items, and make its result more attractive.
