Abstract

FIELD: printing industry, decorative production.

SUBSTANCE: invention can be used in the field of building and finishing materials manufacture, the furniture industry, in manufacture of elements of architectural and landscape design, interior subjects, etc. The method implies that form a decorative layer of a product is created by cloth with drawing on its surface becoming transparent after impregnation with binder and from an opaque base, laid on a layer transparent binder from the interior of a cloth. To get accurate, deep and volume drawing on a product surface as the binder the polyester nonsaturated pitch is used, and polyester silk is used as a the cloth.

EFFECT: method improves product operational qualities.

Description

The invention relates to the field of production of building and finishing materials, furniture industry, elements of architectural and landscape design, interior items.

An analogue of this method is a method of manufacturing decorative products, which consists in deforming a workpiece by compressing it, followed by leveling and applying the image by treating its surface with a dye torch under various directions and drying. Moreover, before deformation of the workpiece, it is impregnated in a dye and reagent solution. In this case, the workpiece is twisted, after technological exposure of the workpiece, an image is applied to it. As the workpiece, various materials are used, including film, for example lavsan. RU 2014237, cl. B44F 9/04, publ. 04/15/1994.

This method cannot provide a predicted surface pattern of a decorative product, because the formation of the picture occurs arbitrarily, in addition, for the same reason, the predictability of color distribution in the figure is not provided, and since the material is opaque, this method does not provide image depth. And also the disadvantage is that when using a film material that is not impregnated with a binder, the solidity of the product is violated, and when the product is used, the effect of delamination of the material appears.

As the closest analogue, a method of manufacturing decorative products, as disclosed in the description of the document SU 51410, cl. B32B 27/04, publ. 07/31/1937. This method provides a predictable pattern on the surface of the products, however, the latter does not have sufficient volume.

The technical result of the invention is to provide a clearer, deeper and volumetric pattern on the surface of decorative products.

To achieve the specified technical result in the method of manufacturing decorative products according to the invention, the decorative layer is formed from a fabric with a pattern on its surface that becomes transparent after impregnation with a binder, and from an opaque substrate laid on a layer of a transparent binder on the inside of the fabric, polyester unsaturated is used as a binder resin, and polyester silk is used as the fabric.

A method of manufacturing decorative products is implemented as follows. A separating layer, for example, wax, is applied to the inner surface of the mold, after curing the separating layer, a transparent binder (e.g., transparent gelcoat) is applied with a brush or spray ~ 0.5 mm thick, after the first layer is cured, a transparent binder (e.g., polyester unsaturated resin) is applied with a brush, or by spraying, after which decorative textile material is laid with the specified pattern, made by the printing method, hand-painted, stencil or some other copying method bom. Then the material is impregnated with a transparent binder and rolled with rollers to remove air bubbles. The next layer is again applied a layer of a transparent binder, possibly of a different color, and after slight drying (so that the layers do not mix), a layer of an opaque binder, which is a substrate, is applied. After the decorative layer is formed, a reinforcing layer is applied by applying a layer of material (for example, fiberglass, glass mat, etc.) impregnated with a binder (for example, polyester resin, epoxy resin, etc.) using fiberglass manufacturing technology, or the specified thickness is gained by pouring the mass (for example, 20% of a polyester resin and 80% of a different-fraction bulk material, such as marble flour, marble chips with a fraction of 0.1-0.3 mm and quartz sand, mix to a homogeneous mass), or by another method. Each layer has adhesion with the previous layer, which ensures the solidity of the product. After the reinforcing layer has hardened, the product is removed from the mold and a decorative product is obtained with a surface having a multicolor, saturated, deep, voluminous, precisely defined pattern.

The material of the decorative layer should be able to be impregnated with a binder and become transparent after impregnation, i.e. The texture of the material should not be visible, but only the pattern on this material, for example polyester silk, is visible. The binder can be of any color, but it is necessarily translucent. The fabric impregnated with a transparent binder becomes transparent and due to several transparent layers and an opaque substrate, the pattern on the surface of the product becomes clear, deep and voluminous. Moreover, this figure is predicted in advance, i.e. It has the possibility of repeated repetition and ensures how pleasing the duration by compiling the product from parts.

The figure No. 1 and No. 2 shows samples of products made by the proposed method.
