Description

The invention relates to methods for the production of synthetic structural products, replacing whole natural granites, diabases and other hard stone breeds, used as decorative protective structures, and can be used to decorate and protect the waterproofing of artificial streams and ponds, the formation of artificial rocks and waterfalls of arbitrary sizes, for decorating unsightly landscape elements.

Known facing sheet [1], containing a coating and a substrate of pressed sheet material, the coating is made of a mixture of a binder and mineral fillers, while in the coating, 1 to 2 parts by weight of the binder accounts for 2.0-2.3 parts by weight of the mineral filler, the coating being applied directly onto a substrate of pressed sheet material. Also known is a decorative product [2], containing a grip with an ornamental stone placed in it, at least one pendant element and a suspension, the product is provided with external and internal metal circuits interconnected, and the inner circuit is formed by a grip for the ornamental stone, to the outer the contour inside and to the capture of the inner contour is attached at its inflection points to a wire with the formation between it and the contours of the eyes, the connection of the circuits is made in the form of tensioned between the eyes ibkih elements are strung on the decorative elements and the outer circuit is connected with an outboard element via the suspension. A disadvantage of the known technical solutions [1] and [2] is the limited functionality due to the inability to use them as decorative cover elements.

Known decorative stone slab [3], characterized by shaping in the form of a plate, and at least part of the front surface of the stone slab is polished, and the polished surface of the stone slab is made darker than its unpolished part (base), at least on one section of the polished surface chips with different densities and depths were made with randomly distributed protrusions and depressions of irregular shape.

Known decorative plate can be used as a cover element, but its operational capabilities are limited, since it cannot cover convex objects.

The closest analogue is a decorative covering element [4] containing an outer layer formed by stone chips and polyester resin mixed with a hardener, characterized in that it contains a domed fiberglass frame made of glass mat impregnated with a polyester resin mixed with a hardener and laid in the manufacture of a convex matrix form, while the uncured fiberglass is applied sand, forming a rough surface during hardening of the resin, and a layer of stone chips and polyester resin 2–6 mm thick is located on the outer rough surface of the frame.

In this solution, decorative cover elements are an imitation of boulders protruding above the ground (granite and sandstone blocks) and are designed to protect and decorate sewer manholes for caissons, septic tanks, ugly stumps, exposed concrete, steel structures, pumping equipment and other ugly places on the landscape. Stones hollow inside allow you to hide any object sticking out above the ground.

The well-known decorative covering element contains a domed fiberglass frame made of glass mat impregnated with a polyester resin in a mixture with a hardener and laid on a convex matrix in the manufacture, as well as an outer layer formed of stone chips and a polyester resin mixed with a hardener. At the same time, sand is applied to the uncured fiberglass, which forms a rough surface during hardening of the resin.

The disadvantages of this technology are the limited forms only by the assortment of form matrices, the structural limitation of the sizes of the products offered. In addition, it is impossible to use stone chips with fractions larger than three millimeters.

In general, the disadvantage of this solution is the integrity of the dome-shaped frame, which limits the dimensions of the product to known frames, the inability to use in complex water elements: in streams, in waterfalls.

The aim of this invention is to eliminate the disadvantages of the prototype.

Technical result: it is possible to decorate and protect the waterproofing of artificial streams and ponds, the formation of artificial rocks and waterfalls of arbitrary sizes, decoration of unsightly landscape elements.

The claimed technical result is achieved due to the fact that the method of creating a decorative stone, in which a decorative covering element is created comprising an outer layer formed by stone chips and polyester resin mixed with a hardener, on top of which a domed fiberglass frame made of fiberglass impregnated with polyester resin is formed mixed with a hardener, characterized in that the frame is formed in three layers, the first of which is made of a reinforcing layer of glass mat impregnated with a polyester resin in mixtures with a hardener, and are applied directly to the decorated area of the waterproofing of the covered object with a characteristic relief segment; the second layer of the covering element is formed from river sand mixed with polyester resin and hardener and is used as a base in which pebbles or stone chips are embedded in fractions up to 100 mm in size; and the third - the top layer is made of a mixture of pebbles, stone chips and resin with a hardener and is formed until the second layer has hardened, and a protective varnish coating is applied on top of the third layer. As a varnish coating use a transparent polyurethane stone varnish. Dry pigments are added to the varnish. Between the reinforcing layer and the second layer, a separation layer of a polyethylene film is applied. Technological seams between the segments are connected with glass mat impregnated with resin with a hardener.

The invention is illustrated in the drawing, which shows a decorative cover element in section. The first reinforcing layer (2) (see drawing) is made applied directly to the decorated area of the waterproofing of the covered object (artificial reservoir: concrete pool bowl, film waterproofing of the pit, ponds made of polyethylene). Thus, the first layer can be applied to an existing characteristic relief segment. It is noteworthy that the decorated base (1), on which the first reinforcing layer is applied, can be formed of any shape and by anything, for example, dried foam concrete or a bunch of rags laid in a plastic bag, as well as any finished shape or relief form of a natural natural object.

If it is necessary to remove the fiberglass copy from the relief, a separation layer of a plastic film is used, which is applied between the first and second layer. The resulting matrix from the first layer and the film can be used to form new clone layers in shape on top of it in three layers.

Fiberglass segments of the right size are assembled at the installation site in the finished product. Technological seams between the segments are connected with glass mat impregnated with resin with a hardener. The proposed method for creating decorative stone allows the creation of riverbeds, reliefs of waterfalls, planting nests for alpine and ground cover plants, and the introduction of artificial moss in the relief of products during the layout of segments.

The second layer (3) of the cover element consists of river sand mixed with a polyester resin and a hardener. Unlike the prototype, it is not final, but serves as the basis for the introduction of stone, shell pebbles or stone chips of large fractions up to 100 mm in size. The second layer (3) gives the thickness of the coating and allows you to apply the next layer (4).

As a polyester resin, an unsaturated polyester resin with a low styrene emission can be used, prepared on the basis of AROPOL M 105 TB orthophthalic acid, which upon hardening provides the necessary strength characteristics.

The third layer (4) is decorative and consists of a mixture of stone pebbles, stone chips of various breeds and fractions, shell pebbles and resin with a hardener.

The principle of connecting the two upper layers (3, 4) is as follows. The pebbles of the third layer (4) are pressed into the yet not hardened second layer (3). After hardening, all three layers (2, 3, 4) behave as a whole, providing protective functions of waterproofing. Using various breeds of stones or pebbles for the third coating layer, we achieve a high degree of decorativeness and naturalness.

After completion of the hardening process, the products (unlike the prototype) are coated with a transparent polyurethane varnish (5) on stone, which avoids atmospheric whitening of the resin. Dry pigments can be added to the varnish to create artistic accents.

Segments made using this technology can also be used to form artificial rocks and stones of any size.

The product is in industrial manufacture, is reliable and durable in operation.
