Abstract

1. A decorative multilayer panel, including layers of solid sheet material located at a distance from one another, and placed in the space between them and bonded with them an intermediate layer, characterized in that two continuous layers of the panel are made of wood fiber boards, 3-4 thickness mm, and the intermediate layer is a waste of these plates and is made in the form of strips, the length of which coincides with the length of the panel, and the width is in proportion to the length equal to 1: 48-50, and adhesive strips are applied to these strips on both sides coats of coarse-grained polyvinyl acetate resin, and the panel, the layers of which are additionally pressed, is provided with an external decorative protective layer of pentaphthalic enamel. The decorative multilayer panel according to claim 1, characterized in that the decorative layer can be monophonic or have a composition of enamels of various colors, applied using a spray gun.

The technical solutions described above do not have the special rigidity and strength of the structural laminate.

Closest to the technical solution proposed as an invention is a multilayer panel comprising sheaths of continuous sheet material located at a distance from one another, a honeycomb core placed between the sheaths having a thickness less than the distance between the sheaths, at least one of which is located on the distance from the honeycomb core, and at least one intermediate layer placed in the space between said skin and honeycomb bonded to

them, and the specified intermediate layer is made of at least one continuous corrugated sheet, the corrugations of which are parallel to the specified skin.

The disadvantages of the above solutions include the complexity of manufacturing, the lack of wear resistance of the product surface and decorative properties.

The technical result of the invention includes the simplification of the process, increasing the wear resistance of the panel surface by creating a protective decorative layer and creating a cheap structural layered material through the use of production waste.

The technical result is achieved due to the fact that in the Decorative multilayer panel, including layers of solid sheet material located at a distance from each other and placed in the space between them, an intermediate layer, two continuous layers are made of wood fiber boards, and their thickness is 3-4 mm . The intermediate layer is a waste of these plates and is made in the form of strips whose length coincides with the length of the panel, and the width is in proportion to the length of 1: 48-g-50.

Coarse dispersed adhesive layers are applied to strips on both sides

polyvinyl acetate resin; layer thickness 0.1 mm. Then the panel, the layers of which are additionally pressed, is provided with an external protective decorative layer of pentaphthalic enamel.

In this case, the decorative layer can be monophonic or have a composition of enamels of various colors, applied with a spray gun.

The figure 1 shows the layout of the layers of the decorative multilayer panels.

1- two continuous layers of the panel

2- inner intermediate layer of waste

3- adhesive joint between layers

4- outer layer of the panel of enamel.

In the manufacture of the panel, the outer coating can have several options: glossy, monophonic, glossy with a composition of various colors of pentaphthalic enamels, applied using an airbrush or on the outer surface of the panel

veneer, which is also varnished, can be cut onto synthetic resin.

The side surfaces of the panel are treated in the same way.

The present invention allows to obtain a cheap composite material for widespread use in the furniture industry, as well as a facing material in the construction of offices and residential premises;

Decorative multilayer panel has a good margin of rigidity and strength, as well as high performance and decorative properties.
