Description

The utility model relates to the field of construction and can be used for external decoration of walls of buildings.

Known building panel (certificate No. 16004, E 04 C 2/00) containing mineral fiber on an organic binder matrix and a finished front coating. Moreover, the matrix can be made of impregnated with an inorganic binder basalt cardboard, cellulose cardboard,

corrugated fiberboard and fiberboard.

The disadvantage of this design is the low decorative properties, a limited range of colors, low tightness of the product and, as a result, unreliable operation.

A facing panel or tile is known (certificate No. 14596, E 04 F 13/14, E 04 C 2/26) containing a bonded face layer based on a binder and a filler, mainly sand, and a carrier layer of thermoplastic polymer material. The thickness of the front layer of this panel is at least 3 mm, and the thickness of the carrier layer exceeds the thickness of the front layer by at least 3 times.

A disadvantage of the known device is its low decorative properties, high weight, limited range

color gamut, low tightness of the product and low performance.

The technical result of the claimed solution is to facilitate the design, improve the quality of the front surface and ensure high performance.

This result is achieved by the fact that the decorative panel contains interconnected face and carrier layers, where the thickness of the carrier layer exceeds the thickness of the face layer, the face layer is made of polyester unsaturated resin and pigment or pigments, and the carrier layer is made of plate material with an inorganic or organic binder moreover, the front and the carrier layers are interconnected by an intermediate layer made on the basis of synthetic resin with a filler, and the back side of the carrier layer and the ends of the decorative layer the surfaces are covered with an insulating layer, while

- the front layer is made up to 1 mm thick;

-plate material is made with a thickness of more than 4 mm;

- as a filler of the intermediate layer using glass material or fine powder;

- the thickness of the intermediate layer does not exceed 4 mm;

- the insulating layer is made on the basis of synthetic resin and filler;

The decorative panel is a sequential

deposited, laid layers: front intermediate / supporting

insulating Where the front and bearing layers are interconnected

an intermediate layer made of a mixture of synthetic resin and filler. In this case, the front layer must be up to 1 mm thick, and the supporting layer in the form of a plate material, which can be used as a particle-cement

g1p

plate, asbestos-cement sheet, fiber-cement sheet, particle board, injection polyurethane foam, etc. A prerequisite is that the plate material is used with a thickness of more than 4 mm.

The intermediate layer may be made of a mixture prepared:

firstly, by impregnating the synthetic resin with glass material followed by polymerisation of the resin, where, for example, glass mat, fiberglass, glass yarn can be used as glass material;

secondly, from a mixture of synthetic resin and

fine-grained powder, for example, stone flour, talc, aerosil, while the thickness of the intermediate layer should not exceed 4 mm.

The preparation of the intermediate layer is made by mixing a synthetic resin with a filler. For example, an acrylic modified resin is used as a synthetic resin, and glass material or fine powder is used as a filler.

The intermediate layer has the following functions:

- adhesive (connection of the front and carrier layers),

compensating (smooths surface defects of the carrier layer),

-insulating (isolation of the carrier layer from the effects of the atmosphere).

The insulating layer is made of a mixture of synthetic resin and filler, followed by polymerization, where a hardener (methyl ethyl ketone peroxide) and, if necessary, an accelerator (cobalt octoate) are used as filler.

The insulating layer of the decorative panel is applied to protect against atmospheric effects.

The insulating layer performs the functions of:

- insulation of the surfaces of the carrier layer, not covered by the intermediate layer from environmental influences (moistening, abrasion) by creating a vapor-, moisture-proof, durable, low-rough surface;

-compensation of stresses caused by the polymerization of the intermediate layer.

The front layer is a polymerization product: a mixture of a polyester unsaturated resin and an inorganic pigment or inorganic pigments. The front layer is made as single- or multi-color using inorganic pigments of several colors and shades at once, smooth or non-smooth surface.

The decorative panel is obtained as follows.

A mixture is prepared for the face layer of a polyester unsaturated resin and inorganic pigment. For the color of the face layer, several inorganic pigments are introduced into the mixture. As the material of the front layer, you can use a mixture of industrial production, for example, a gel protective and decorative coating “Gelcoat into which inorganic pigment (s) are introduced. The front layer is sprayed onto the inner surface of the rigid form, which is coated with, for example, paraffin, so that the decorative finished panel is easily separated from the rigid form. Then stand the rigid form with the applied face layer at room temperature for the time necessary for

polymerization of the mixture, for example, 3 hours. To improve the color on the decorative panel, the front layer can be

layered. In this case, it is necessary to apply layer after layer with various inorganic pigments, then the polymerization of each of the layers.

After the end of the polymerization of the face layer, an intermediate layer is applied to it with a spray. If necessary, the intermediate layer is compacted with something, or they are rolled by improvised means. Then, a carrier layer in the form of a plate material is laid on the intermediate layer. And thus, the polymerization of the intermediate layer proceeds under load.

After polymerization of the intermediate layer, an insulating layer made of synthetic resin and filler is applied to the back side of the carrier layer and the ends of the decorative panel.

To accelerate the polymerization processes, they are produced in thermal chambers at a temperature of 40-60 ° C, for 20-40 minutes.

Thus obtained decorative panel has high performance and improved quality of the front surface.
