Description

The invention relates to the production of art and decorative products, namely a variety of gypsum products, art panels, etc., and can be used for the manufacture of souvenirs and various decorations, as well as in children's creativity.

In the manufacture of decorative products, in particular in the process of casting works of art from plaster, specially made forms are used. The manufacture of such forms is quite laborious. Moreover, in some cases it is impossible to create a form that allows to embody any imagination of the artist.

A known method of manufacturing a panel, including dosing of a binder, water, colored filler, mixing them to a paste-like state, molding the surface of the product, exposure to drying and curing at room temperature. Before molding, the contour lines of the future image are applied to the rigid base. Pre-prepared colored pasty compositions are sequentially applied to the base along contour lines that limit the application surface of the composition of a certain color in accordance with the figure. The subsequent color composition is applied to an adjacent contour, not allowing the previous composition to dry, with the possibility of partial application of compositions of different colors and their mixing at the boundaries of contact of the compositions with each other. After drying and curing process the surface of the product by grinding (patent RU 2371325 C1, B44C 5/04, B44C 1/20, publ. 10.27.2009).

The disadvantages of this method are its complexity, limitation in obtaining a variety of products, as well as the inability to obtain a clear three-dimensional picture of a complex product.

Closest to the technical nature of the claimed is a method of manufacturing a decorative product, including the preparation of a mixture based on a mineral binder, pouring it into a mold and curing until completely hardened, further removing and drying the product (patent RU 2320479 C1, B28B 1/00, C04B 14 / 38, published March 27, 2008).

The known method does not allow to obtain volumetric decorative products with a complex pattern, of any size and complex configuration. Products obtained in this way are not decorative.

The technical result of the claimed invention is to simplify the manufacturing process of a decorative product, as well as to increase the decorativeness and aesthetics of the resulting product by obtaining a clearer, deeper and more voluminous picture of its surface.

The claimed technical result is achieved by the fact that in the method of manufacturing a decorative product, including the preparation of a mixture based on a mineral binder, pouring it into a mold and holding until fully hardened, further extraction and drying of the product, gypsum diluted as a mixture based on a mineral binder water in a mass ratio of 1: 1.5, and quartz sand of a fraction of 0.2-0.4 mm, moistened with water in a ratio of 10-15 ml of water per 1 kg of quartz sand and made with a print, is used as a form m relief image of the product corresponding to the image of the manufactured decorative product.

In this case, quartz sand is poured into a container of waterproof material or poured in a layer on a horizontal surface.

The impression of the relief image in the form can be obtained using one or more natural objects or artificially made patterns having different shapes and sizes.

As natural objects, shells, or plants, or leaves can be used.

As artificially made patterns, animal figures or sculptures can be used.

In quartz sand before pouring the mixture can be placed objects of natural origin.

Exposure of the gypsum mixture poured into the sand is carried out for 30-45 minutes.

After removing the product from quartz sand, its residues from the product are removed with a brush or washed with a stream of water.

After drying the product can be carried out protective and decorative processing of the product.

As a protective and decorative treatment of the product can be applied by applying paint, or varnish, or paintwork on the surface of the product.

The invention is illustrated by photographs of decorative products obtained using the claimed method.

The manufacture of a mold based on quartz sand of a fraction of 0.2-0.4 mm and water taken in the ratio of 1 kg of quartz sand to 10-15 ml of water, and the printing of a relief image corresponding to the image of the manufactured product, allows you to get bulk products of any size and any form, while not requiring large energy costs and the use of complex mechanisms.

In the manufacture of the mold for pouring gypsum mixture, quartz sand of a fine fraction of 0.2-0.4 mm is used. The use of quartz sand of a larger fraction (more than 0.4 mm) does not allow creating a clear picture, since the poured gypsum mixture seeps through coarse sand. And the use of quartz sand of a too fine fraction (less than 0.2 mm) is unprofitable, since it is less accessible.

For the manufacture of molds, colored quartz sand can be used.

In the manufacture of the mold, quartz sand is poured into a container of waterproof material. To obtain bulk products, the capacity must be deep enough. To obtain flat works (including those having large sizes) quartz sand is poured in a layer on a flat horizontal surface.

Quartz sand is moistened with water in a ratio of 10-15 ml of water per 1 kg of quartz sand. When water is added more than 15 ml or less than 10 mm, the form does not have the properties necessary to obtain a high-quality impression of a relief image.

The relief image in the form (quartz sand) corresponding to the image of the decorative product being produced can be printed using one or more objects, including glued onto a template, stencils and other various objects.

Any objects of natural (natural) origin (shells, leaves, plants, etc.) of various shapes and sizes can serve as a template. An example (photo) of a finished product imitating leaf veins and obtained using a plant leaf as a template is shown in the photo of Fig. 1. An example of a finished composition using several objects (leaves) is shown in figure 2.

Artificially made objects (figures of animals, fish, etc.) of various shapes and sizes can be used as a template. An example (photo) of a finished product imitating the faces of people and obtained using a sculpture as a template is shown in Fig. 3.

After imprinting the relief image in quartz sand, the objects used, templates or other elements (by which the imprint is performed) are removed.

An example of a mold made of quartz sand before pouring gypsum mixture is presented in the photo of figure 4.

Extract of the mixture based on a mineral binder (gypsum mixture) is carried out for 30-45 minutes. Exposure less than 30 minutes does not allow the gypsum mixture to harden sufficiently. If the gypsum mixture is left for more than 45 minutes in a moist quartz form, the gypsum may lose its strength and the product will become brittle. The exposure time of the gypsum mixture may also depend on the quality of the gypsum and its concentration. To obtain a more durable product can be applied, for example, gypsum brand G-16.

The remains of quartz sand after removing the product from the mold (quartz sand) are easily removed with a brush or washed off with a stream of water.

It is better to dry the product in an upright position to avoid deformation of the product.

After drying, the product can be left in the form as it was received, without subsequent processing (see, for example, in the photo of figure 1), or protective and decorative processing of the product can be carried out.

As a decorative processing of the product can be applied gilding, tinting, aging, coloring (see examples in the photo of figure 5 and 6), etc. Also, paint, varnish, paintwork can be applied to the surface of the finished product. To increase the strength of the product, it can be impregnated with various compositions that prevent gypsum hygroscopicity.

The claimed method allows you to create castings that simulate natural forms. Gypsum in this case absorbs small particles of sand from the surface of the mold and looks like a stone. The claimed method significantly expands the artist’s creative capabilities, making it possible to produce complex relief images, for example, a relief composition imitating mountain ranges (see the product’s photo in Fig. 7). Moreover, the claimed method for manufacturing decorative products is quite simple to use.

Also, to create a complex interesting composition of a decorative product in quartz sand (in the form), solid objects of natural origin, such as shells, starfish, etc., can be put before pouring gypsum mixture. When pouring gypsum mixture into quartz sand (form), objects of natural origin are not immersed in gypsum, since the sand protects them, they are as if sunk into sand and gypsum is not poured around them. An example of such an embodiment of the product composition using starfish is shown in Fig. 8.

The claimed method allows to produce not only various flat, but also voluminous products. The implementation of such options is shown on the example of the manufacture of poultry (Fig.9) and wheels (Fig.10).

A method of manufacturing decorative products is as follows.

Initially, a mixture based on a mineral binder is prepared and a mold is made for the subsequent pouring of a gypsum mixture into it. As a mixture based on a mineral binder, gypsum is used, which is diluted with water in a mass ratio of 1: 1.5 and mixed until a pasty state is obtained. For the manufacture of the mold take quartz sand fraction 0.2-0.4 mm, which is poured, for example, into a container of waterproof material. Wet silica sand with water in a ratio of 1 kg of silica sand per 10-15 ml of water. Next, a relief image is printed in the obtained quartz base, corresponding to the image of the manufactured product. For example, a print is made in a quartz basis using a natural (natural object) sheet of a plant.

The prepared gypsum mixture is poured into the mold made of ceramic sand and kept for 30-45 minutes at room temperature until completely hardened.

After that, the resulting product is removed from quartz sand (mold) by simply shaking off and washing off the sand, and the remaining quartz sand from the product is removed with a brush.

Maintain (dry) the product at room temperature, or, to accelerate drying, in a warm room, or near a radiator. Drying time depends on the temperature and humidity of the room. The dried product should be much lighter and make a loud sound when tapped.

Thus, the claimed method allows to obtain decorative products that simulate natural forms, including those that are close in appearance to natural stone, wood or any plant material. Using the proposed method, you can recreate images of wind, waves, create plant and other thematic compositions. You can make a mold from sculpted plasticine or whatever and print it in the sand, creating a mold for casting.

This method gives the gypsum surface a sandstone appearance, as the smallest particles of sand remain in the upper layer of gypsum. You can use colored sand, creating interesting effects without coloring with white gypsum.
