The disadvantage of analogs is the small area of products, which complicates the installation process, and the material used for the manufacture of decorative panels is not environmentally friendly enough, since they use unhealthy epoxy resins and phenols.

The technical problem to be solved by the claimed invention is the creation of a method for manufacturing a decorative panel and a decorative panel that is prefabricated due to the large area of the panel itself without the cost of additional preparation of the wall surface before installation, which do not have these disadvantages.

The technical result of the claimed invention is to improve the environmental friendliness and quality of decorative products and to simplify installation.

The technical result of the claimed invention is achieved in that the method for manufacturing a decorative panel, according to the invention, includes the following steps: a sheet blank is cut to obtain a final format of the base with a width of 915-930 mm, gelatin preheated to a temperature of 55-80 ° C is applied in an even layer on the surface of the base. glue by applying rollers, after which a cork sheet 2 mm thick is laid on the prepared adhesive surface with a margin at the edges, which is rolled out by means of a pneumatic pressure roller and the edge is cut, then dried under pressure for 12 hours, after which a decorative pattern is applied with water-dispersion paint by indirect printing, drying is carried out at a temperature of at least 250 ° C and a finish coating with a water-dispersion protective varnish, followed by stream drying, after which rusts are applied to a depth of 3 mm, imitating brickwork, on a CNC milling machine, and also by the fact that decorative the panel is made by the method according to claim 1 and contains a base from a sheet blank and a cork sheet.

In addition, a sheet blank of MDF or HDF, or fiberboard is used.

In addition, the cutting of the sheet blank is carried out on a panel saw.

Increasing the environmental friendliness of the product is ensured through the use of environmentally friendly material from natural components in the manufacture: wood board with an emission class E1, comparable to the emission of natural wood; gelatin glue - natural material; cork - tree bark; water based paintwork.

The composition of the decorative panel components:

1. MDF/HDF/Fibreboard base

2. gelatin glue

3. leaf cork

4. water-dispersion paint

5. water-dispersion varnish

The method for manufacturing a decorative panel includes the following production steps:

or, or laminated chipboard (hereinafter referred to as chipboard), or chipboard (hereinafter referred to as chipboard)

1. In the cutting shop, a sheet of medium density fiberboard (hereinafter referred to as MDF) is taken with a format of 2440 * 1220 * 3.2 mm, or a format of 2440 * 1830 * 3.2 mm (each format can be of different thickness, like 3.2 mm, and 4 mm / 5.5 mm / 6 mm), or a sheet of high-density fiberboard (hereinafter - HDF) - 2800 * 2070 * 3 mm, or a sheet of fiberboard (hereinafter - fiberboard) - Possible formats: 2745 * 1700 * 3.2 mm, 2745 * 1220 * 3.2 mm, 2440 * 1220 * 3.2 mm, a part of it is sawn off on a format-cutting machine to obtain an MDF base format - 2440 * 930 * 3.2 mm , HDF 2070*930*3 mm, fiberboard - 2745*930*3.2 mm/2440*930*3.2 mm. The final format of the base should be 915-930 mm wide, while the length of the sheet does not matter. This width format is necessary because the application equipment does not allow the use of a sheet wider than 1000 mm and, in addition, the width of the sheet cork is 1000 mm.

2. Next, the cut sheet is moved to another workshop with glue application equipment:

- prepare the adhesive composition - gelatin glue is heated in a "water bath" to a working temperature of 55-80°C;

- the gelatin glue is pumped with a pump onto the shafts that apply it, which distribute it over the surface of the base sheet in an even layer (the sheet passes through the equipment, exits with a layer of glue);

- on the receiving table (it is also a laminator), a cork sheet 2 mm thick is applied to the base sheet with the applied adhesive composition with a margin along the edges;

- the operator, using a pneumatic pressure roller, rolls out the cork sheet over the area of the base, expels the air, straightens the folds;

- cut off the excess cork sheet, cutting it along the edge of the base.

3. The resulting panel is sent for 12 hours to dry under pressure.

4. Next, the panel is moved to the decorative coatings workshop, where

- on the painting line, a decorative pattern is applied with water-dispersion paint. The pattern is applied by transferring shafts. The drawing is applied industrially, the method of indirect printing. Drying also takes place in the equipment, at a temperature of 250 degrees C and above;

- a water-dispersion protective varnish is applied as a finishing layer, followed by flow drying.

5. Next, the panel is moved to another workshop, where, on a CNC milling machine, rusts are applied to a depth of 3 mm, imitating brickwork.

6. Next, the finished decorative panel is packaged.

The claimed decorative panel, obtained by the claimed method, has a rigid base, which allows it to be a prefabricated structure with a finished decorated coating (construction of partitions, installation on existing draft walls, installation on GVL, OSB, tongue-and-groove blocks) without preliminary surface preparation, which simplifies installation and improves the quality of the decorative panel. The uniqueness of the declared decorative panel consists in the combination of a rigid base made of MDF / HDF / fiberboard and a cork coating with imitation of brickwork, made in volume with dimensions: with a width of 0.93 meters, the height can be 2.07 or 2.44 meters, the panel area is 1.925 m ² or 2.27 m ² .
