Description

The invention relates to the field of construction and arts and crafts and can be used for facade decoration and interior coatings, the manufacture of tiles, panels, decoration of household items such as caskets, vases, etc., from the waste from the production of colored and window glasses, as well as using glass breakdown, which is formed in large quantities in everyday life, the problem of recycling which has not yet been resolved and is very acute.

A known method of manufacturing facing plates for the exterior decoration of buildings (RF patent No. 2196052, IPC B 44 C 5/04, publ. 10.01.2003, BI No. 1-2003), in which an adhesive layer is formed on the substrate by applying a binder in a continuous layer, after which crushed stone-like material (natural stones, artificial stones or ceramic particles) with a particle size of 1-10 mm is applied, and the resulting semi-finished product is cured to obtain the target product.

The resulting product has a rough surface with sharp edges that can cause injuries, and in addition, the graininess of the surface when using a material with a fraction size of 1-3 mm leads to the reflection of a large number of light rays, as a result of which the texture of the product is not visible, the effect is painted surface. The use of a large fraction increases the consumption of the binder, as well as the weight of the product.

It is known to use crushed glass for artistic and decorative decoration of facade surfaces of fragments of buildings and interiors, panels, panels, etc., as well as in the manufacture of mosaic works (Yu.E. Gromov, V.P. Lezhepekov, G.S. Severinova “ Industrial decoration of building facades ”, M.,“ Stroyizdat ”, 1980, pp. 11-15). The method includes the steps of preparing the surface of the products for coating, applying a layer of a binder to them and adding crushed glass with a grain size of 0.63-5.0 mm. If necessary, a layer of fine-grained materials is fixed with a colorless varnish.

The disadvantage of this method, limiting the scope of its application, is the increased risk of injury when working with glass having sharp edges and corners, not enough high artistic and aesthetic appearance of the product.

The present invention is aimed at eliminating the risk of injury when creating coatings, which will significantly expand the use of glass breakage, solving the problem of its disposal. In addition, the proposed method of decorative processing allows you to get a completely new artistic and aesthetic appearance of the product.

The solution to this problem is achieved by the fact that the glass break is processed, subjected to comprehensive grinding or polishing, which is carried out using abrasive material in an aqueous medium. Use a glass battle with a fraction size of 5-50 mm. The surface intended for decorative processing is pre-treated, after which an adhesive layer is formed on it, and then - a decorative layer, laying processed color fractions of glass. If necessary, you can fix the decorative coating on top with colorless varnish.

Pre-processing glass break, they solve two problems at once: eliminate injuries, thereby improving working conditions, and get a matte surface. It is known that light falling on a dull surface is reflected diffusely from it, i.e. scattered in all directions. The aesthetic effect of the image printed on the product is enhanced.

The attached graphic material shows:

figure 1 - one of the possible structural options for devices for processing glass break;

figure 2 is a fragment of a building panel with a decorative coating in section (according to existing technology);

figure 3 is the same according to the proposed technology.

The following notations are used on graphic materials:

1 - tumbling drum; 2 - pieces of glass break; 3 - abrasive material (quartz sand, silicon carbide, etc.); 4 - water; 5 - panel; 6 - adhesive layer; 7 - glass; 8 - panel.

The device operates as follows. In tumbling drum 1, approximately to its middle, 50% (by volume) of glass break 2 and 50% of abrasive material 3 are loaded, after which water 4 is poured into the drum so that it covers the surface of the loaded glass mass and abrasive. Turn on the drum rotation drive and rotate it at a speed of 1-50 rpm (the rotation speed is selected depending on the required degree of processing of the material). During rotation, pieces of glass from the bottom and on the right side of the drum rise up in the direction indicated in FIG. arrow to the critical point (pivot point), after which they turn over and slide off, as shown in FIG. arrows down in a single layer system. At the same time, each piece, making numerous circular movements up and down, grinds sharp corners and edges about the “sides” of its “neighbors”, grinding a piece of glass over all its surfaces. Tumbling time is determined by the degree of readiness of the material.

After grinding, sharp corners and edges are smoothed out, and the glass surface acquires a beautiful matte color.

If necessary, polished pieces can be polished in the same drum, using the appropriate abrasive material and fillers, polishers - wooden cubes, sawdust, pieces of leather, etc.

An example implementation of the proposed method

The wall panel 8 was used as the substrate. The surface of the panel was leveled, the shells, pores and cracks were closed with cement-sand mortar, cleaned and then an adhesive layer was formed of polymer-cement paste. A polyvinyl acetate emulsion was used as the polymer component of the paste, 3 parts of cement were used for 1 part of the emulsion. A pre-polished glass with a fraction size of 10-15 mm was laid on a prepared even layer of binder, forming a decorative layer in accordance with a given pattern, selecting fractions of the desired color and size. The finished product was left to dry for 24 hours.

The resulting product has a beautiful matte surface and looks very aesthetically pleasing.

The present invention allows to secure work when laying pieces of glass on the adhesive layer during the artistic and decorative surface treatment of products and to increase the artistic and aesthetic value of these coatings, which they give to the polished or polished pieces of broken glass. The scope of broken glass is expanding significantly, and thus, the state-environmental problems of its disposal on an industrial scale are solved.

Claims (1)

A method of decorative processing of products, including surface preparation, the formation of an adhesive layer, on which a decorative layer is then formed using glass breakage, characterized in that a glass break of 5-50 mm in size is used, which is subjected to comprehensive grinding beforehand.
