Description

The utility model relates to the industry of building materials and products, namely to molded composite building products with a colored decorative outer layer of various shapes and sizes, for example, floor and road surfaces, stairs, etc., which can be used for road, housing, etc. .d.

Known non-slip artificial stone (patent RU No. 2247086, IPC С04В 26/02, dated February 27, 2005) containing an inorganic aggregate and resin having a rough surface with exposed inorganic aggregate, the average depth of concave grooves on the surface of the stone being in the range from 0 , 02 to 1.0 mm, and the volume fraction of inorganic aggregate is from 25 to 75%. The disadvantages of stone include the relatively high cost of its production.

Known floor tiles with anti-slip surface (patent RU No. 62415, IPC E04F 15/08, E04F 11/16 of 04/10/2007) containing a base of mineral material, artificial stone or ceramic, the non-slip surface of which is made on the front side of the base one or several recesses with a rubber or polymer coating applied therein and protruding above the surface of the tile. The disadvantages of this tile include its relatively high cost and complexity of production.

Known molded element and composite building product (patent RU No. 79887, IPC С04В 28/02 of 01/20/2009), consisting of a material containing a silicate binder, a pigment and a plasticizing additive, a filler having a particle size of not more than 8 mm, and including surface colored fragments with a closed spatial contour, the inner core of which contains the largest filler particles, and the shell is an astringent and smaller filler particles. This product is taken as a prototype.

The disadvantages of this product include the difficulty of obtaining a non-slip surface comparable to a rough surface with exposed inorganic aggregate.

The technical problem solved by the utility model is to create an effective anti-slip surface on the product while maintaining the technological (increased density of the product, the absence of pores in the mass of the product) and the artistic merits of the prototype.

The essence of solving the technical problem is that the product consists of a material containing a silicate binder, a filler, a pigment, a plasticizing additive and contains a filler having a particle size of not more than 8 mm and includes surface-colored fragments with a closed spatial contour, the inner core of which contains the largest filler particles, and the shell is an astringent and finer filler particles, while part of the surface of the product has a rough surface with exposed inorganic fill oil.

The manufacturing process of molded products is as follows. An inorganic aggregate, for example granite sifting with a particle size of 5-10 mm, is poured into the mold, in special recesses, preferably 3-4 mm deep. A silicate binder, for example, Portland cement, and a mineral filler, for example, granite screenings with a particle size of not more than 8 mm, its mixture with sand or sand, and also, if necessary, pigment, are loaded into a rotating vane-free concrete mixer and mixed until homogeneous. After that, water is introduced with a plasticizer dissolved in it, for example, C-3, and, possibly, other functional additives, and stirring is continued. After the introduction of water into the concrete mixer, the formation of plastic spools of approximately spherical shape and their gradual enlargement begins in it. Pigments are added to the concrete mixture at the moment when the size of the pellets becomes mainly about 3-6 cm. Upon reaching the desired size of the pellets, pigment (or pigments) is introduced into the concrete mixer and 10-20 seconds after the end of the introduction of pigments, pour concrete mixture in forms located on a vibro-table, performing horizontal oscillatory movements, preferably with a frequency of 50 Hz. As a result of vibration, the pellets are deformed (spread), and the mixture evenly fills the mold, including filling the space in special recesses between the particles of the inorganic aggregate filled with dust. During mixing in the concrete mixer, the pigment penetrates into the reels to a depth of 2-3 mm, but the surface of each reel is painted with a different degree of pigment penetration, which subsequently gives the product a unique marble-like pattern, while the natural texture of the inorganic aggregate will appear in areas with a non-slip surface. At the end of the molding, the molds with the products are subjected to natural drying on the racks until the strength sets in full, after which the products are easily removed from the molds. Products are characterized by increased density, the absence of pores and the presence of areas with an effective anti-slip surface. To prevent partial “leakage” of concrete under the particles of the inorganic aggregate, during molding on a vibrating table it is possible to pre-fill the space in the special recesses of the mold between the particles of the inorganic aggregate filled with an epoxy binder, polyurethane, “liquid rubber” or other cementitious component with their possible tinting with the most appropriate color range of the main surface of the product. The use of such inorganic aggregate binders increases the effectiveness of the anti-slip surface of the product. Molded products in accordance with the utility model can be made in the form of plates, tiles for floors or stairs, paving slabs and other products.

The essence of the utility model is illustrated by the attached figures 1-2. Figure 1 shows a schematic section of a molded product with a non-slip surface, figure 2 shows a schematic section of a molded product with a non-slip surface with an additional inorganic aggregate binder, where are indicated:

1 - surface of the mold;

2 - inorganic aggregate;

3 - concrete mixture;

4 - additional binder of inorganic aggregate.

The following are examples that describe the process for producing molded products with a non-slip surface.

EXAMPLE 1. Red granite sifting with a particle size of 5-10 mm is poured into molds, into special recesses forming an anti-slip surface of the product, filling them with recesses in one layer. 43 kg of Portland cement grade 500 DO, 69.3 kg of granite screenings with a particle size of 0 to 5 mm, 29.7 kg of sand are loaded into a rotating vane-free concrete mixer and mixed until homogeneous, after which 7.8 kg of water is dissolved with it 430 gr. plasticizer C-3 and continue mixing. After the introduction of water into the concrete mixer, the formation of pellets of approximately spherical shape and their gradual enlargement begins in it. When the size of the spools reaches 3-6 cm, 430 g of white pigment (titanium dioxide) is introduced into the concrete mixer, after 7 seconds 430 g of red pigment, 130 g of blue pigment and 215 g of black pigment are introduced. After another 7 seconds, lay smaller reels (2-3 cm) on granite sifters poured into molds, and then turn on the vibrating table vibrator. After that, the remaining concrete mix, starting with larger spools, is laid out in forms located on the vibrating table. As a result of vibration, the pellets are deformed (spread), and the mixture evenly fills the mold. At the end of the molding, the molds with the products are covered with a plastic film and subjected to natural drying on the shelves until they are fully cured, after which the products are easily removed from the molds. The finished product has a color that imitates red granite with an anti-slip surface, interspersed with natural red granite.

EXAMPLE 2. In molds, in special recesses forming an anti-slip surface of the product, lubricated with a grease separator (wax dissolved in kerosene, or shoe creams and polishes is suitable for this purpose), black granite sifting with a particle size of 5-10 mm is filled, filling it recesses in one layer and fill them with an epoxy binder in the amount of about 0.4-0.5 of the total volume of the recesses in the molds under the anti-slip surface. For better flow of the epoxy binder, during the filling, a short-term inclusion of the vibrator of the vibrating table for 2-3 seconds is allowed. In this case, the epoxy binder should fill the recesses forming the anti-slip surface of the product, not more than 0.8-0.9 of their volume. The composition of the epoxy binder is 90 volume parts (parts by weight) of epoxy resin ED-20 or Erohu 520, 10 parts by weight plasticizer DEG-1.50 o.h. hardener Etal-45M. Next, after 1-1.5 hours, the process of obtaining a molded product is carried out in the same way as in example 1, with the following differences. When the size of the pellets reaches 3-6 cm, 300 g of white pigment (titanium dioxide) is introduced into the concrete mixer, after 8 seconds at the same time 300 g of yellow pigment, 140 g of brown pigment and after 6 seconds the whole concrete mix is laid out in forms located on a vibrating table with included vibrator. The finished product has a color imitating amber with a non-slip surface of a partially transparent brown color, having volume interspersed with natural black granite.

EXAMPLE 3. In molds, in special recesses forming an anti-slip surface of the product, lubricated with a grease separator (wax dissolved in kerosene, or shoe creams and polishes is suitable for this purpose), marble sifting with a particle size of 5-10 mm is filled, filling it with recesses in one layer and pour them with VODIPREN 90 liquid rubber in a volume of about 0.4-0.5 of the total volume of recesses in the molds under the anti-slip surface. For a better flow of liquid rubber, a vibrating table vibrator is turned on during pouring. In this case, liquid rubber should fill in the recesses forming the anti-slip surface of the product, not more than 0.8-0.9 of their volume. Further, after 10-15 minutes, the process of obtaining a molded product is carried out in the same way as in example 1, with the following differences. When the size of the pellets reaches 3-6 cm, 560 g of white pigment (titanium dioxide) is introduced into the concrete mixer, after 10 seconds 300 g of black pigment are simultaneously added, and after 7 seconds the entire concrete mixture is laid out in molds located on the vibrating table with the vibrator turned on. The finished product has a color that imitates classic marble with a rubber anti-slip black surface interspersed with natural marble.
