Description

The invention relates to the field of production of artistic and decorative products that can be used in the interior of premises, in the manufacture of doors, furniture, and can also find application in architecture.

The prior art method of manufacturing a decorative panel, described in A.S. No. 697356, Cl. B44C 1/28, publ. 11/25/1979 and adopted as the closest analogue for the first variant of the method. In the known method, individual elements are cut out, transferred to the picking table, the completed plate is laid in a metal mold on a conveyor for feeding into the heat chamber. The mold is equipped with a pressing device, in the places of the seams, glue is applied, which is used as an epoxy resin. In order to prevent leakage of glue when passing through the seams, wrapping paper is laid on the bottom of the metal mold.

The disadvantages of this method are its low productivity and high cost of manufacturing the panel.

In addition, there is a known method of manufacturing a decorative panel, described in the patent of the Russian Federation No. 2289513, Cl. B44C 1/26, publ. 08/10/2006, selected as a prototype for the second and third versions of the proposed solution.

The method is as follows. Put a drawing on an elongated wooden blank, set it on the carriage of the milling machine, produce a cut in accordance with the figure. After the slot is made, the cut is mechanically cleaned and filled with an adhesive based on epoxy resin, capable of fixing the insert in the slot when solidifying. The insert is made of precious wood. After the installation of each insert, the fixing composition is dried until completely cured.

The disadvantages of this method are its low productivity and high cost of manufacturing the panel.

The objective of the proposed technical solution is to create a method of manufacturing a decorative panel.

The technical result of the proposed solution is to increase the productivity of the process, improve the operational and decorative-artistic qualities of the panels and reduce the cost of manufacture.

The specified technical result is achieved by the fact that the method of manufacturing a decorative panel includes cutting the source material into parts with the desired edge shape, placing the parts on a synthetic material and connecting them with each other using a cured substance based on epoxy resin. In this case, a wood-based or wood-composite material is used as a starting material, and an adhesive film is used as a synthetic material, which is preliminarily placed on an even flat surface with an adhesive layer upward, stretched and fixed to prevent the curing substance from spreading. Lay the parts on a synthetic adhesive film with a gap in relation to each other. The gaps between the parts are filled with a curing agent, which is used as a colored epoxy composition prepared using an amine hardener in an amount of 5-10 wt.% By weight of the epoxy resin. Details are pressed to the surface, after polymerization of the epoxy resin, the workpiece is removed from the synthetic adhesive film, filed, polished and varnished.

A method of manufacturing a decorative panel also includes drawing a pattern on the starting material, making slits in accordance with the pattern, and treating the resulting holes with a curing agent based on epoxy resin. In this case, a wood-based or wood-composite material is used as a starting material, in which slots are made in accordance with the pattern throughout the thickness of the plate material to obtain through holes. Then the obtained part is laid on a synthetic adhesive film, which is preliminarily placed on an even flat surface with the adhesive layer upward, stretched and fixed to prevent the curing substance from spreading. The processing of the through holes obtained in accordance with the figure is carried out by pouring them with a curing agent, which is used as a colored epoxy composition prepared using an amine hardener in an amount of 5-10 wt.% By weight of the epoxy resin. The workpiece is removed from the synthetic adhesive film after polymerization of the epoxy resin, sanded, cut into a format and finished with varnish.

In addition, a method of manufacturing a decorative panel includes drawing a pattern on the starting material, making slits in accordance with the drawing to a depth less than the thickness of the plate material to produce recesses, and treating the resulting recesses with a curing agent based on epoxy resin. At the same time, wood-based or wood-composite material is used as the starting material. The processing of the obtained recesses is carried out by pouring them with a curing agent, which is used as a colored epoxy composition prepared using an amine hardener in an amount of 5-10 wt.% By weight of the epoxy resin. After polymerization of the epoxy resin, the part is divided into billets, sanded, and varnished.

Due to the placement of the plate material and parts obtained from it on a synthetic adhesive film placed with the adhesive layer upward, the plate material and parts are fixed on its surface. With this fixation, there is no displacement and the cured substance does not spread under the plate material and the parts made of it. This allows you to speed up the productivity of the process and reduce the cost of manufacture.

For the manufacture of panels using a colored epoxy composition prepared using an amine hardener in an amount of 5-10 wt.% By weight of the epoxy resin. The use of such an amount of hardener for the preparation of the resin allows to accelerate the performance of the process, reducing the polymerisation time of the resin. In addition, the use of the epoxy composition of the proposed composition improves the operational and decorative-artistic qualities of the panels.

The invention is illustrated by drawings.

Figure 1 shows a panel made of individual parts;

Figure 2 is a top view of the plate material with slots throughout its thickness;

Figure 3 is a side view of the plate material with slots throughout its thickness;

Figure 4 is a top view of a plate material with recesses;

Figure 5 is a side view of a plate material with recesses.

The panels are made as follows.

A method of manufacturing a decorative panel includes cutting a slab of wood or wood-composite material into parts 2 with the desired edge shape. Parts 2 can be cut using any improvised tool, in particular, a band saw, milling equipment, laser cutting can also be used. Lay out parts 2 with gaps 5 with respect to each other on a synthetic adhesive film 1, previously placed on a flat flat surface with the adhesive layer up. The film 1 is pulled along the long side and fixed with screws 3, the long edges of the film 1 are folded and pressed with rails 4 on the screws 3 to prevent the spread of the colored epoxy composition. The gaps 5 between parts 2 are filled with a colored epoxy composition. Details 2 are pressed to the surface. After polymerization of the epoxy resin, the workpiece is removed, filed, polished and varnished.

Also, a decorative panel can be made as follows. Put a drawing on a plate wood or wood-composite material. Slots 7 are made in accordance with the figure using milling equipment over the entire thickness of the plate material. The resulting part 6 is laid on a synthetic adhesive film (not shown in FIGS. 2 and 3), previously placed on an even flat surface with the adhesive layer up. The resulting slots are poured with a colored epoxy composition. The workpiece is removed after polymerization of the epoxy resin, polished, cut into a format and finished with varnish.

In addition, the decorative panel is made as follows. Put a drawing on a plate wood or wood-composite material. Carry out the slots in accordance with the figure with the help of milling equipment to a depth less than the thickness of the slab material with obtaining recesses 8. Pour the colored epoxy composition into the obtained recesses. After polymerization of the resin, the part is divided into billets, polished, and varnished.

The colored epoxy composition is obtained by thoroughly mixing the epoxy resin with an amine hardener, followed by adding the dye to the mixture in the amount necessary to obtain the desired shade. K-115 epoxy resin can be used as an epoxy resin, and polyethylene polyamine in an amount of 5-10 wt.% By weight of the epoxy resin can be used as an amine hardener.
