Description

The invention relates to the manufacture of artistic and decorative mosaic products, glass mosaic panels.

A known analogue (RF patent No. 20149422). The essence of the method is as follows: blocks of different colors are sawn into rectangular plates, connected into packages, cut out according to a given pattern from the package of plates flat mosaic elements. The plates are laid on a greased substrate and the flat mosaic elements of one color are inserted into the plates of another. Fill the seams with a binder, grind and polish the front surface. Sawing is carried out using a laser installation or stone-cutting disk machines, a mosaic pattern is applied on the bottom plate and cuts with a diamond disk.

The method does not allow to produce complex, small-sized products using glass mosaic technique, decorative paintings and panels that are unique in artistic value, because the specifics of using technical installations predetermines the work with stone (marble, granite).

The prototype of the invention according to the technical essence is a method of manufacturing a mosaic product (RF patent No. 2021153), when a thermoplastic polymer film is laid on a solid base and uniformly heated to a temperature below the melting temperature and not higher than the temperature of its destruction. Mosaic elements are laid on the film and loaded with a load of 0.001-0.01 MPa. When using mosaic elements of various thicknesses, they are loaded with loose material heated to a temperature of 50-100 ° C above the melting point of the temperature of polyethylene. The process is quite laborious, and laying out the complex elements of a small mosaic is difficult. In addition, you have to work with hot materials (harmful working conditions). Possible percent defective due to uneven deformation of the film under load.

Objective: to optimize the way the mosaic is recruited from the point of view of the complexity and intensity of the process, increase the strength and aesthetic characteristics of glass mosaic products, reduce the number of defects and the ability to accurately predict the final result.

The essence of the invention: on a solid base with a thickness of not more than 15-17 mm, pre-made from a concrete mixture of a binder, in accordance with a given shape and dimensions of the future product, a mosaic image is made of flat polychrome glass plates of regular geometric shape with a size of 3-5 mm according to the working sketch, holding the plates together and with the base of the plate with a thin layer of binder of the same composition as the base, in the following ratio of components, wt.%:

white cement M 400 20-25 sand 58-63 gypsum 12-25

The solution has the necessary strength (strength 38 MPa) and aesthetic properties (whiteness of BWW 85.3%).

The transparency of the glass allows the advantage of using the background color, emphasizing the color-harmonic composition of the glass mosaic panel, achieving specific effects. Example

To create an artistic and decorative glass-mosaic product, a working sketch in color and an outline drawing on tracing paper are developed.

In accordance with the sketch, colored glass is selected according to the developed color composition.

Stained glass is subjected to cutting into plates of regular geometric shape with a size of 3-5 mm. A box is made of wood or cardboard - a box corresponding to the dimensions of the manufactured product (560 × 420 × 60). It was revealed that preliminary it is required to prepare a concrete slab, and to carry out the set on a solid base with laying a thin layer of binder. Using gypsum and mastic is not only economically unprofitable, but technologically unacceptable due to the increase in the thickness and weight of the product, which makes it non-tectonic and bulky. It is practically impossible to compose an image from small plates of glass on a non-solidified basis. Thanks to the solid foundation, it became possible to carry out work on a set of mosaics in several stages. Prepare a concrete mortar.

The concrete mixture has optimal properties in the following ratio of components, wt.%:

white cement M 400 25 sand 63 gypsum 12

The solution satisfies the necessary indicators of compressive strength (strength 38 MPa) and aesthetic properties (whiteness of BWW 85.8%). Gypsum, introduced additionally, reduces the setting time to 20-30 minutes and the hardening period to 35-40 minutes, positively affects the whiteness and slightly reduces the strength of concrete. As a result, concrete reaches the required strength in a period of 17 days, the required degree of mobility of the mixture is maintained, which satisfies the method of laying and its compaction.

The transparency of the glass makes it possible to advantageously use the white color of the background, contributing to the harmonization of the color-composite solution of the glass mosaic panel.

The solution is poured into the caisson in 3 stages: the first layer of the solution, reinforcing fastening (a metal mesh with an area of 0.235 m ² with mesh sizes 15 × 15 mm is used as reinforcement), the second layer of the solution, the thickness should not exceed 15-17 mm.

It is recommended to add one part of PVA glue to the cementitious solution on which the plates are laid out, which increases the adhesion of surfaces.

The plate is dried to a solid state. The caisson is disassembled, the edges and the working surface of the plate are mechanically treated with sandpaper. A sketch is drawn through tracing paper. Compilation of the image is carried out by the direct mosaic method by laying out a binder of polychrome glass plates on a thin layer of a solution. At the end of the set, the product is ground and polished.

The technical result of the invention is to increase the strength and aesthetic characteristics of glass mosaic products due to the presence of a solid concrete base, which makes it possible to produce complex, small sizes, unique in artistic value decorative paintings and panels, eliminating the need to create complex temperature conditions for melting the binder and the percentage of marriage due to uneven deformation of the polymer film under load.

Optimization of the method of recruitment of glass mosaics and the choice of concrete composition used as a binder can significantly simplify the duration of the process, reduce raw material costs and easily change the range and subject of products depending on consumer demand. Considering the factors, the method is rational, affordable, relatively cheap and can be recommended both in production and in private workshops.
