RU2534061C1 - Method of production of coated decorative articles - Google Patents

Abstract

FIELD: woodworking industry.

SUBSTANCE: MDF panel, or HDF, or laminated chipboard or particle board is cleaned from dust using brushes of dust collecting plant, followed by coating on the cleaned surface of four layers of ground, followed by infrared drying after each layer of ground. After application of the fourth layer of ground drying of the panel is carried out in a drying tunnel. Then the primer layer is applied on the panel with rollers, followed by drying the ultraviolet tunnel, after that the image and/or pattern is applied with the digital printer with UV ink. Then the coating is applied, followed by drying in the UV tunnel, then the panel is polished, then glossy or matt varnish is applied or 3D embossing with the pattern texture, after which the final drying is carried out in the UV tunnel, and the article is covered with a protective film.

EFFECT: increasing the economical efficiency of the article production, increase in quality of decorative articles and durable operation of the articles.

Description

The invention relates to the field of furniture production and can be used in the manufacture of decorative products with a coating, such as furniture.

The prior art method for the manufacture of decorative coated products (http://eurogroup.su/articles/kashirovanie-plit-dsp-dbp-mdf), including laminating the surface of the material of the product with decorative paper films.

The disadvantages of this method are the low performance of the coating, short service life, low wear resistance, problematic care, because the coating does not tolerate wet wiping surfaces.

As a prototype, the applicant selected a method known from the prior art for manufacturing decorative products coated with Hot Coating technology (http://www.negotiant.ru/product_catalog/furniture_manufacturing/molded_products/lineslaminating/473/), including the operation of applying material to a sheet of panel varnish products combined with digital printing on it.

The specified method can significantly increase the resistance of the coating to ultraviolet rays, impact resistance and resistance to abrasion and scratches. The main disadvantage of this method is the lack of efficiency in the manufacture of panels.

The objective of the present method is to eliminate the disadvantages of the prototype.

The technical result is to increase the efficiency of production of the product, at the same time, the quality of decorative products is increased, which leads to long-term operation of the products.

The technical result is achieved by the fact that the MDF panel, or HDF, or chipboard, is cleaned of dust by brushes of a dust collecting unit, followed by applying four layers of soil to the cleaned surface, followed by infrared drying after each soil layer, and after applying the fourth soil layer, the panel is dried in drying tunnel, then a primer layer is applied to the panel with rollers, followed by drying in an ultraviolet tunnel, after which an image and / or drawing is applied by a digital printer with UV ink, after it is coated, followed by drying in a UV tunnel after the panel is polished, then coated glossy or matt varnish or 3D embossed with a textured pattern, after which the final drying takes place in the UV tunnel and the article is covered with a protective film.

At the same time, the doors of the bedside table, or the front side of the chest of drawers, or cabinet doors, or countertops, or kitchen facades, etc., can be used.

The method is as follows. Panel - medium-density fiberboard (hereinafter - MDF) or high-density fiberboard (hereinafter - HDF), or a laminated chipboard (hereinafter - chipboard), or particleboard (hereinafter - chipboard), etc. . - the particle board is cleaned of dust by brushes of the dust collecting unit. Four layers of soil are successively applied to the cleaned surface, followed by infrared drying after each soil layer. After applying the fourth layer of soil, the panel is dried in a drying tunnel.

After drying, a primer layer is applied to the panel with rollers. The primer is dried in an ultraviolet (hereinafter - UV) tunnel.

Then a digital printer with UV ink is applied to the image or drawing of the future product or the texture of the surface or elements of the product.

After drawing a picture, the panel is coated using Hot Coating technology. The panel is dried in a UV tunnel. Then an excess coating layer of Hot Coating is polished and, depending on the needs of the customer, a glossy varnish or a matte varnish is applied to the panel or 3D embossing with the texture of the drawing is applied.

The panel is finally dried in a UV tunnel, the product is covered with a protective film and packed in pallets for shipment to the customer.

Line productivity is 20 meters per minute.

The difference between the method and the existing ones is that on the panel you can put an image of parts of the finished product (a ready-made design solution with a full cutting map), for example, the entire front part of the kitchen set. The furniture manufacturer cuts the panel and receives an artistically and designer finished product of the front part of any cabinet furniture with a full cutting map.

These panels can be used in the manufacture of kitchen sets, hallways, wardrobes, bedroom sets, countertops, office furniture, chests of drawers, cabinets, etc.

Claims (1)

A method of manufacturing decorative coated panels, characterized in that the MDF, or HDF, or chipboard, or chipboard panel is cleaned of dust by brushes of a dust collecting unit, followed by applying four layers of soil to the cleaned surface, followed by infrared drying after each soil layer, after which the fourth layer of soil, the panel is dried in a drying tunnel, then a primer layer is applied to the panel with rollers, followed by drying in an ultraviolet tunnel, and then a digital printer with UV ink on ositsya image and / or pattern, and then coated and subsequently dried in a UV tunnel after the panel is polished, then coated glossy or matt varnish or 3D embossed with a textured pattern, after which the final drying takes place in the UV tunnel and the article is covered with a protective film.
