Definitions

• the invention relates to a natural stone imitation which has the shape, color and aspect of the natural stone and for internal or external decorative structures such as fountains, rocks with waterfalls, in furnishings encased by imitations of natural stone, uses of ceilings, walls and floors, among other things , is used.
• the invention also relates to methods for producing this natural stone imitation.
• a manufacturing process of natural stone imitation which consists in the treatment of the glowing basic blast furnace slag with pellets with a granulation of 20 mm, obtained from the dust collected from the smoke stack on which the ferro alloys melt down, burned furnace brick debris and tar sludge.
• a product that can replace the concrete is obtained from various types of waste that are evaluated in this way (patent, Romania, no. 73950).
• the natural stone imitation eliminates the disadvantages of the known natural stone imitations by the fact that it consists of three layers, a discontinuous on the surface, with different colors and a thickness of 0 ... 5 mm, an intermade continuous, unique color , with a thickness of 2 ... 5 mm and an inner, which is the base and resistance layer and has a thickness of 3 ... 10 mm, so that the artificial stone has the shape and color of the natural stone.
• the surface layer consists of 28 ... 48% of the weight of polyester resin with reinforcement, or
• Polyvinylchloride or polystyrene possibly with a crosslinking agent surcharge, 50 ... 70% of the weight of quartz powder and 2 ... 10% of the weight of pigments
• the intermediate layer consists of 28 ... 48% of the weight of polyester resin with reinforcement, or polyvinylchloride or Polystyrene, possibly with crosslinking agent surcharge, 50 ... 70% of the weight from quartz powder and 2 ... 10% of the
• Em method of imitation natural stone (artificial stone) for decorative structures consists in that one carries in a rigid or flexible structure, which mimics the shape of a natural stone, by spraying or brushing on some of its inner parts the mixture for the The surface layer is left on until this layer is strengthened, the mixture for the intermediate layer is applied to the entire inner surface by spraying or brushing and one is left until this layer is strengthened, unifying with the already reinforced parts of the first layer on which inner surface thus formed, a continuous layer of the mixture of polyurethane with reinforcement is applied by spraying, or a continuous layer of the mixture is applied by spraying or brushing on the basis of polyester resin, reinforcement and glass fiber to allow this layer to be reinforced, a structure is applied three fixed, united among them The result is layers that are manually pulled
• Another method of manufacturing natural stone imitation (artificial stone) for ornamental structures consists in carrying a continuous layer of the mixture by spraying on a rigid or flexible structure which mimics the shape of a natural stone on the entire inner surface Polyurethane with reinforcement, or by spraying or brushing, a continuous layer of the mixture is applied on the basis of polyester resin, reinforcement and glass fiber, until this layer is strengthened, the layer obtained is manually pulled out of the rigid or flexible structure and one apply a continuous layer of the one-color mixture for the intermediate layer to its entire outer surface by spraying or brushing, until this layer is strengthened, after which a layer of mixtures for the surface layer with different colors is discontinuously applied over it uf, until this layer is strengthened and at the end the structure obtained from three combined layers is blown with sand on its entire outer surface.
• the artificial stones have such a shape that they can be very easily placed one on top of the other in various arrangements, receiving a rock aspect or other natural appearance, or if they are flat, used for veneering.
• Example 1 A rigid structure is made from a single piece or from several parts, which are assembled using ordinary screws. The structure is obtained from polyester resin with reinforcement and glass fiber. It represents a form (a negative) that mimics the shape of a natural stone but has not completely closed its surface. This shape can have smaller, medium or large dimensions, depending on the type of construction in which the natural stone imitation (artificial stone) is used.
• mixtures which contain 28 ... 48 parts by weight of polyester resin with reinforcement (which is added at the time the mixture is used), 50 ... 70 parts by weight of quartz powder and 2 ... 10 parts by weight contain pigment compatible with the resin for coloring.
• the mixtures differ according to the dye and its quantity, so that they have different colors and even shades. They are made by simply mixing the resin with quartz powder, pigment and afterwards with the amplifier. The rigid structure as a form is placed in the working position with the
• a layer of a compound eg wax
• a thin layer of the prepared mixture is then applied to some parts of the inner surface of the structure using a spray blower.
• these parts can have different shades, as they will appear as some ribs or indentations in the final product.
• the applied parts of the layer are so thick that they can harden to a maximum thickness of 5 mm.
• a continuous layer with another spray blower is applied to the entire inner surface of the structure, from a single mixture prepared as before, which will determine the background color of the future imitation natural stone.
• the colors can be from white to dark gray, passing through different shades of gray, or from white to dark brown passing through different shades of cream, or different shades of red, etc., similar to the coloring of the natural stones.
• the third layer of polyurethane solution with reinforcement is gnawed on by spraying.
• the screws of the rigid structures are unscrewed if they are made of several parts or.
• the product obtained is manually pulled out of the mold if it is one piece, and it is blown off with sand which is thrown out of an air gun on its entire outer surface in order to give this surface the appearance of the natural stone.
• the first two layers can be applied with a brush.
• a polyvinyl chloride or polystyrene solution can be used, possibly with a cross-linking agent, in the same proportion to the weight.
• Example 2 It can be seen as in Example 1, with the difference that the structure used as the mold is flexible, made of silicone rubber, it consists of a single part and does not have to be coated with wax or another substance on the inside. In this case, the product is easily pulled out of three layers without deforming because the rubber mold is elastic.
• Example 3
• the inner third layer which is applied by spraying or manually with a brush, consists of 20 ... 35 parts of the weight Glass fiber and 65 ... 80 parts by weight polyester resin solution with amplifier. This mixture is easily made by simply mixing the glass fiber with the resin solution and at the time of use with the amplifier.
• the glass fibers can be in the form of fabrics, threads or in chopped form.
• the natural stone imitations can be arranged individually or in groups, they can have different shapes (depending on the structure used), as in nature . So you can create artificial rocks, with or without waterfalls, caves, walls with bumps, pools with uneven walls and floors, fountains or any other desired buildings inside or outside of the building, which have the goal of giving the impression of a natural landscape.
• Such buildings are suitable for decorating hotels, restaurants, clinics, houses and apartments, kindergartens, zoos and other interiors, or the parks, botanical gardens and zoos, courtyards of villas, etc., because the natural stone imitation from the presented Invention Weatherproof and resistant to weather conditions in a variable range (from summer to winter).
• Another use of natural stone imitation is in the frame of some furniture parts (bookcase, showcase, closet, etc.) in a decorative structure made of these artificial stones or in combination with other materials or workpieces (e.g. made of stainless steel or another metal, Glass, wood) for creating an internal or external design.
• a decorative structure made of these artificial stones or in combination with other materials or workpieces (e.g. made of stainless steel or another metal, Glass, wood) for creating an internal or external design.
• the plate-shaped products from Example 4 are used for veneering walls, ceilings, floors, some furniture parts or for any other application in which natural stone plates are used.
