In such a decorative insulating product, the paintwork 4 is applied to the front surface of the outer layer 1.

Below are examples of the manufacture of decorative thermal insulation coatings with various percentages of components.

Example 1. In a paddle mixer, 50 wt.% Of crushed wood bark wastes with a particle size of 0.1 to 10 mm are loaded and, with stirring, 50 wt.% Of a polyvinyl acetate dispersion is added to a homogeneous mass. Then the mixture is unloaded onto fiberglass (1 mm thick), where it is leveled with a squeegee (guide knife) over the area of fiberglass

to a thickness of 8-15 mm, after drying the mass for 20-40 minutes, fiberglass with a layer deposited on it is passed between the rolls with a gap of 10-12 mm. The resulting package is kept at room temperature for 4-6 hours to remove the remaining moisture, then cut into a predetermined size. If necessary, a decorative finishing coating is applied to the front surface.

Example 2. In a paddle mixer, 95 wt.% Wood sawdust with a particle size of 0.1 to 0.5 mm is loaded, and with stirring, a 5 wt.% Solution of polyurethane adhesive is added to the mixer until a homogeneous mass is obtained. Then the mixture is unloaded onto a metal mesh (0.15 mm thick and a mesh size of 20 mm), where it is leveled with a squeegee (guide knife) to the thickness of 1-1.5 mm over the mesh area, a mesh with a layer deposited on it is passed between the rolls with a gap of 1.0-1.2 mm. The resulting bag is kept at room temperature for 3-4 hours to remove the solvent, then cut into a predetermined size. If necessary, a decorative finishing coating is applied to the front surface.

Example 3. 65 wt.% Of ground wood waste with a particle size of 1 to 5 mm are loaded into a paddle mixer and 35 wt.% Rubber latex is added to the mixer with stirring.

obtaining a homogeneous mass. Then the mixture is unloaded onto kraft paper (0.1 mm thick), using a squeegee (guide knife) it is leveled across the paper to a thickness of 5-6 mm, after drying the mass for 200-40 minutes, paper with a layer deposited on it is passed between rolls with a gap of 4-5 mm. The resulting package is kept at room temperature for 4-6 hours to remove the remaining moisture, then cut into a predetermined size. If necessary, a decorative finishing coating is applied to the front surface.

Example 4. In a paddle mixer, 75 wt.% Of crushed wood bark wastes with a particle size of 1 to 3 mm are loaded, and 25 wt.% Of an acrylate adhesive emulsion is added to the mixer with mixing to obtain a homogeneous mass. Then the mixture is unloaded onto the fabric (capron 0.2 mm thick), using a squeegee (guide knife) it is leveled by the area of the fabric to a thickness of 3-4 mm, after drying the mass for 10-20 minutes, the fabric with a layer deposited on it is passed between rolls with a gap of 3-4 mm. The resulting package is kept at room temperature for 4-6 hours to remove the remaining moisture, then cut into a predetermined size. If necessary, a decorative finishing coating is applied to the front surface.

Example 5. In a paddle mixer load 45 wt.% Crushed waste wood bark with a particle size of from 1 to 5 mm and 40 wt.% Wood sawdust with a size of from 0.1 to 0.5 mm and is poured into the mixer with stirring 15 wt. % solution of rubber glue until a homogeneous mass. Then the mixture is unloaded onto cardboard (1 mm thick), using a squeegee (guide knife) is leveled on the cardboard area to a thickness of 4-5 mm, after drying the mass for 10-15 minutes, cardboard with a layer deposited on it is passed between the rolls with a gap 5-6 mm. The resulting bag is kept at room temperature for 4-6 hours to remove the solvent, then cut into a predetermined size. If necessary, a decorative finishing coating is applied to the front surface.

In accordance with the above examples, the values of thermal conductivity coefficients of the claimed decorative thermal insulation product and prototype are presented in the summary table.

As can be seen from the table, the thermal conductivity of packages based on waste wood and binder is lower than the package of birch bark due to the presence of air bubbles,

filling the interstructural space and being a poor conductor of heat. According to its values, the thermal conductivity coefficient of the claimed decorative thermal insulation product approaches the cork performance, which is 0.045-0.075 W / m × deg.

A comparative analysis of the proposed utility model and prototype reveals the distinctive features of the claimed decorative thermal insulation product in comparison with the closest analogue, which ensures that it meets the criterion of "novelty."

The presence of distinctive features provides the design with the achievement of a positive effect, expressed in the creation of a new decorative thermal insulation product with high performance and providing an extension of the scope.

The use of the claimed utility model in construction and other industries as a decorative insulating product ensures its compliance with the criterion of "industrial applicability".
