Description

The invention relates to the production of materials used in the production of coatings for the protective and decorative finishing of internal and external surfaces of buildings and structures, as well as products for various purposes, more specifically to the technology for the manufacture of silicate paints, and in particular to methods for producing a single-component pure silicate paint and a method for producing used while the intermediate product is serpentinite cake.

The inventions simultaneously relate to the processing technology of natural mineral raw materials, namely serpentinite, which is a common natural mineral, rich deposits of which are available in the Russian Federation and other countries: USA, China, India, Great Britain, Germany, Canada, and therefore its use seems promising direction of expansion of the raw material base of the paint and varnish industry and other industries.

The second and third of the methods indicated above in the title are intended for use in the first and relate to it as part and whole.

The main document regulating the domestic production of silicate paints - traditional two-pack silicate paints - continues to be GOST 18958-73 "Silicate paints" [1]. At the same time, a rather large number of patent documents have been and are devoted to the issues of improving the technology for the production of silicate paints, improving their various properties.

As a rule, there is only one reason for new research in this area. She is known and is common to the entire paint industry. This is the need to use local raw materials and the need for profitable disposal of waste from local industrial production (see copyright certificates of the USSR and RF patents No№: 767154, publ. 09/30/1980 [2]; 823402, publ. 04/23/1981 [3]); 1502589, publ. 08/23/1989 [4]; 1728270, publ. 04/23/1992 [5]; 1756325, publ. 08/23/1992 [6]; 1825806, publ. 07/07/1993 [7]; 1828867, publ. 07/23/1993 [8]; 2007430, publ. 02/15/1994 [9]; 2041900, publ. 08/20/1995 [10]; 2160753, publ. 12/20/2000 [11]; 2272820, publ. 03/27/2006 [12]; 2294946, publ. 03/10/2007 [13]; 2294947, publ. 03/10/2007 [14]).

At the same time, developers are able to obtain silicate paints with improved properties in various parameters: adhesion and physicochemical properties of the coating [2, 3, 5-8]; weather resistance, water resistance and frost resistance (USSR author's certificate No. 617421, publ. 07/17/1978 [15], No. 717110, publ. 02/25/1980 [16], [2, 4, 7]); acceleration of silicatization [16]; hiding power [3, 4, 8, 10, 13, 14]; pigment saving [5]; fire resistance (USSR author's certificate No. 337528, publ. 05/05/1972 [17]); tightness of the paint layer [15]. The inventors also pay attention to the modification of liquid glass used in the production of silicate paints in order to increase vitality - the stability of its parameters over time [3, 7]. Finally, a method is proposed to give silicate paint an important value in paints of the lower price category, to which silicate paints have traditionally been attributed, with almost no property - thixotropy [12].

Moreover, in the majority of the abovementioned security documents, it is proposed to improve the production technology and properties of the standard (“prescribed” in GOST 18958-73 [1]), namely, two-pack or two-component silicate paint, consisting of liquid glass and a dry pigment part. After mixing these two components, the paint should immediately be used, since its viability, as a rule, does not exceed 8 hours [1]. This means that the final, final operation of the paint production process, and at the same time, the manufacturer of the two-component paint actually shifts responsibility for the quality of the resulting product to the consumer. And this despite the fact that the technologies proposed in the security documents for mixing use special industrial mixers [3, 4, 7, 15], ball mills [6, 16], and even autoclaves [5]. And this fact holds back the consumption of remarkable in many respects and certainly environmentally friendly pure silicate paints.

At the same time, reputable international industrial groups: the German Henkel KGaA and Deutsche Amphibolin Werke (DAW), the French Saint-Gobain, the Finnish Tikkurila and others are stably supplying one-component dispersion-silicate paints developed over 30 years ago, the main advantages of which are compared to purely silicate paints are the simplicity of their use and long shelf life - viability (European patent No. 0041212, publ. 05.25.1981 [18]; US patent No. 4361659, publ. 11/30/1982 [19]; German patent application No. 3314475, opu block 10.25.1984 [20]; US patents No. 4512808, published on 04/23/1985 [21]; No. 4347285, published on 08/31/1982 [22]; No. 4539351, published on September 3, 1985 [23]; No. 4677160, published 06/30/1987 [24]; No. 4535109, published on 08/13/1985 [25]; Japan patent No. 0639568, published on 05/25/1994 [26]). Russian patents are also known, in which the subject of the invention are one-component dispersion-silicate paints [9-14].

However, with all the advantages of dispersion-silicate paints: their physical and construction properties, good durability, based on double silicification or double adhesion (when liquid glass is chemically bonded both with special fillers inside the paint and with the painted surface), such water-repellent properties modified paint is deprived of the main, initial advantage of silicate paint - the ability to "breathe". The presence in its composition of organic polymers: butadiene styrene latex [7, 11-14, 18, 19], copolymers of ethylene or methyl vinyl ether [20, 21], polyorganosiloxane [12, 13], rubber latex [22] and others [23, 24 ] - tens of times [15] reduces the breathability of the paint coating. And only the traditional, two-component, purely silicate paint forms open-cell protective coatings that are highly permeable to air: oxygen, carbon dioxide and water vapor. It is traditional paint that has the well-known dust and dirt repellent properties, as a result of which it has an undeniable advantage for use in painting building facades in areas of industrial pollution, it is characterized by a long service life of coatings (facades painted a quarter century ago and today look great) and environmental friendliness, comparable, perhaps, only with environmental friendliness of "old" oil paints on natural drying oil.

Therefore, world manufacturers (Kreidezeit Naturfarben, Germany and others) in the 90s resumed production of "Reine Silikat-farben" - traditional, purely mineral, organic polymeric two-component silicate paints or, as they are called today, eco-colors. Moreover, as mentioned above, the main factor restraining the growth of production and consumption of these traditional paints is their incomplete readiness for use, their semi-finished products, two-component, as well as short, 8-hour pot life, i.e. mandatory use immediately after preparation.

The objective of the proposed invention is to create a technology for environmentally friendly, without organic additives, single-component pure silicate paint with high vitality.

Most of the patents mentioned above describing methods for producing silicate paints have one common feature: they use soluble glass in liquid form to prepare paints.

An exception is the method described in the copyright certificate [5], where the initial component for the preparation of purely silicate paint is a silicate block containing solid soluble glass. The silicate block itself can be obtained, for example, according to the method described in USSR author's certificate No. 1680625, publ. 09/30/1991 [27].

The method [5] is closest to the invention according to the first method of the proposed group.

According to the method [5], first in a ball mill, a joint grinding of the solid components of the paint — crushed silicate block with filler and pigment, which activates the surfaces of the particles of the components — is performed. Then the grinding result is combined with the liquid phase in the form of water, adding the latter to the prepared dry mixture in a ratio of 1: (2.5-3), loaded into an autoclave and processed at 95-100 ° C for 1-1.5 hours.

The paint prepared by this method should be immediately applied to the surface to be painted. The coating needs to be dried for 10-15 minutes at 70-90 ° C, and then cured in a dryer for 0.5-1 hours at a temperature of 150-180 ° C.

The obvious disadvantages of this method are:

- the need for autoclaving, which - given that the paint must be used immediately after preparation - should actually be done at the construction site, which, of course, is difficult;

- the need for high-temperature drying of the coating, which, obviously, makes it impossible to use such paint for painting facades or interior walls - i.e. what silicate paints are mainly used for;

- the final technological operation - the actual preparation of the paint itself - the combination of solid components with water is performed without mechanical activation, which makes the paint obtained by the method [5], to a lesser extent, a chemical compound and a more simple mixture of solid and liquid components with low viability.

The proposed method for producing silicate paint is aimed at achieving a technical result consisting in solving the aforementioned problem, namely, in obtaining a one-component pure silicate paint with high viability. At the same time, the problem of achieving the indicated results is solved using inexpensive and widespread serpentinite raw materials. This raw material is used at the initial stage of the proposed method to obtain serpentinite cake, which in this method is an intermediate product containing soluble solid glass, which is also used as a silicate block in the method [5], which is closest to the proposed one.

Below, when revealing the essence of the proposed method and the description of examples of its implementation, other types of achieved technical result will be named.

The proposed method for producing silicate paint, as well as the specified closest known method, includes grinding a product containing solid soluble glass, and combining the result of grinding this product with a liquid phase in the form of water.

To achieve the above technical result in the proposed method, in contrast to the closest known to it, as a product containing solid soluble glass, use serpentinite cake, which is obtained by fusion of crushed raw serpentinite raw material with a chemical reagent. As the last use alkali. Wherein prior to performing said alloying prepared serpentinitschelochnoy batch containing alkali and serpentinite with a ratio weight of alkali / w serpentinite of M _w / 200 3M _ut / 200 where M _ni - the molar mass of the alkali [g / mol], with the addition of water to yield homogeneous pasty batch consistency. The prepared serpentine-alkali batch is dosed at working doses in the form of lumps or pellet blanks and the specified fusion is performed by sintering the obtained working doses in the furnace until they cure, resulting in serpentinite cake in the form of solid lumps or granules. Said solid lumps are subjected to said grinding after their preliminary crushing or granules. In this case, the combination of the grinding result of crushed lumps or granules with the liquid phase in the form of water is carried out directly in the grinding process, carrying it out in a ball mill with water. Water is added prior to the acquisition of the paint consistency product obtained during the grinding process.

As can be seen from the foregoing, in the proposed method there is no autoclaving process, and the final operation of the paint preparation is the connection of solid components and water at room temperature and normal pressure. Drying of painted surfaces using paint obtained by the proposed method also occurs under normal conditions.

Smaller than the mass of alkali that is in the indicated interval will not give the right amount of soluble glass in the cake, and a larger one will make the cake more expensive and may remain unreacted.

With the described preparation of paint, a very wide range of mass proportions of serpentinite cake and water is possible, due to their joint grinding in a ball mill. In terms of mechanochemistry, co-milling is the co-mechanoactivation of components, in this case, sinter and water, which leads to the formation of a new stable homogeneous system - a one-component silicate paint with primary chemical bonds between solid and liquid particles. The experience of using the resulting paint showed that these primary chemical bonds formed as a result of mechanochemical reactions exist stably at rest and break when mechanically exposed to the paint both when it is mixed and when applied to the painted surface, i.e. when exposed to the paint by the force of the mixer, the force of the brush, paint roller or pressure force of the nozzle of the spray gun. But as soon as the influence of an external force ceases, the broken bonds are immediately restored and the paint again turns into a stable jelly. In other words, the paint obtained by the proposed method has the property of thixotropy. This paint lies on a brush without dripping, and does not drip on the painted surface.

The actual mass ratio of sinter to water during grinding in a ball mill is selected depending on which hiding power of the paint is required. So, if it is supposed to carry out technically complex painting of building facades in 1 time, the ratio of cake to water is better to take 3: 4, when painting the internal walls of buildings for 2 times, this ratio can be 1: 2.

Obtained by the proposed method, the paint does not contain synthetic polymers and is purely silicate. It is also one-component, does not precipitate and remains homogeneous during prolonged storage.

Given that traditional pure silicate paints use two varieties of soluble liquid glass - on sodium and on a potassium basis, it is advisable to use sodium hydroxide or potassium hydroxide as the alkali in the preparation of serpentine-alkali mix at the stage of production of serpentinite cake.

The resulting paint has a nice silver-gray color, which is explained, in particular, by the presence of iron in the composition of serpentinite. To clarify the paint, the initial ground serpentinite material can be subjected to magnetic separation - iron removal.

Any alkali-resistant pigments can be used to pigment the resulting paint.

The process of obtaining serpentinite cake is part of the complete technological process of the proposed method for the production of single-component pure silicate paint from serpentinite. This part of the complete process can also be carried out as an independent production. The process of self-production of serpentinite cake is the subject of the second invention of the proposed group.

A product of the process of fusion of ground serpentinite together with chemical reagents - serpentinite sinter is proposed by different authors for use in industrial production as a raw material for subsequent processing (USSR author's certificate No. 193465, publ. March 13, 1967 [28]; RF patent No. 20111638, publ. 04/30/1994 [29]), and as a final product (Kozaru TV Forsterite ceramics based on natural calcium-magnesium silicates. Abstract of dissertation for the degree of candidate of technical sciences. Pe MSCI State Technical University, 2007 [30]). So, in [30], a method was proposed that includes preliminary calcination of serpentinite powder at 1173K; mixing calcined serpentinite powder, mass fraction 84% with chemicals: magnesium oxide - 14% and calcium borate - 2%; subsequent grinding of the mixture; synthesis (preliminary firing) of the mixture at 1493K; grinding pre-fired mixture; mixing the ground mixture with a chemical compound; compression molding of a mixture mixed with a binder; sintering the molded mixture at 1250-1270K. As a result of the last operation, accompanied by a phase transition of serpentinite - forsterite, a forsterite ceramic product is obtained.

An obvious disadvantage of this method is its high energy consumption, which, of course, increases the cost of the resulting product. At the same time, this method successfully solves the problem of reproducing the properties and quality of an existing product - ceramics that were previously made from other raw materials, which became less affordable over time.

In the methods according to copyright certificates [28] and [29] for obtaining serpentinite cake, crushed serpentinite is fused with ammonium sulfate. The cake is ground and leached with water, followed by fractional neutralization and the separation of metal hydroxides from the solution. In both methods, during the sintering process, free ammonia is released, which forms toxic and explosive compounds with atmospheric oxygen. Moreover, in the method [29], ammonia is captured and condensed for recycling in the process. The presence of such operations significantly complicates the method, but can be justified given the fact that the obtained cake in this method is not the target product, but is used after grinding and leaching with water, followed by fractional neutralization to separate magnesium hydroxide from the solution. However, for all the technological difficulties of this method, obtaining serpentinite cake in the process of its implementation is not accompanied by the release of ammonia into the environment.

The method of obtaining serpentinite cake according to the copyright certificate [29] is the closest to the proposed one.

The proposed method is aimed at obtaining a technical result, which consists in obtaining serpentinite cake suitable for use in the production of silicate paint.

Below, when setting out the essence of the proposed method and particular cases of its implementation, other types of the achieved technical result will be named.

The proposed method for producing serpentinite cake, as well as the specified closest known method [29], involves the fusion of crushed serpentinite feedstock with a chemical reagent.

To achieve the named technical result in the proposed method, in contrast to the closest known to it, alkali is used as the mentioned chemical reagent. Before performing said alloying prepared serpentinite alkaline batch containing alkali and serpentinite with the ratio: weight of alkali / w serpentinite of M _w / 200 3M _ut / 200 where M _ni - the molar mass of the alkali [g / mol], with the addition of water to obtaining a homogeneous pasty consistency of kneading. The prepared serpentinite-alkaline kneading is metered into the working doses in the form of lumps or pellet blanks and the specified fusion is performed by sintering the obtained working doses in the furnace until they are cured, resulting in serpentinite cake in the form of solid lumps or granules.

Smaller than the mass of alkali that is in the indicated interval will not give the right amount of soluble glass in the cake, and a larger one will make the cake more expensive and may remain unreacted.

The cake obtained by the method described above, in contrast to the cake obtained in the closest known method [29], contains solid soluble glass (soluble silicates of sodium, potassium, etc., depending on the alkali used). In this case, the determining requirement for the processing of said serpentinite-alkaline kneading is to ensure its conversion to the solid phase by dehydration and thermal curing during sintering, regardless of the specific conditions of this process.

Considering the fact that in traditional purely silicate paints two types of liquid soluble glass are used - on sodium and on potassium basis, it is advisable to use sodium hydroxide or potassium hydroxide as the alkali in the preparation of serpentine-alkali mix at the stage of production of serpentinite cake.

Serpentinite cake obtained by the described method, along with the intended use for the above method for producing silicate paint according to the first invention of the proposed group, is, at the same time, a product suitable for direct use.

Possessing refractory properties, the serpentinite sinter obtained by the described method, in fragmented form, can act as a packed mass or refueling metallurgical powder in the manufacture of articles for lining thermal units in various industries: metallurgical, chemical, and building materials industries. In a crushed, ground or granular form, such a cake also has sorbing properties and can act as a sorbent for the purification of oils from iron compounds, as well as non-ferrous and heavy metals: zinc, copper, nickel, lead and cadmium. When dosing serpentine-alkali batch by laying out portions into molds and subsequent sintering in molds, the resulting cake is ready-to-use piece-shaped refractory products.

Serpentine-alkali batch can be used as a material for sealing burn-outs and cracks resulting from the destruction of the lining of blast furnaces and other furnaces. Serpentinite cake, which is then formed during the heating of the furnace, restores the destroyed refractory lining.

In one of the particular cases of the implementation of this method, the dosage of serpentine-alkaline kneading can be carried out by extrusion and cutting to obtain portions of the kneading in the form of cylindrical granules. As a result of this process, sinter is obtained in a form suitable for use as a finely granulated sorption material. Serpentinite cake obtained by the considered method is well stored, reloaded and transported, like, for example, iron ore metallurgical cake.

In the case where there is an independent production of serpentinite cake according to the second invention of the proposed group described above, the method for producing silicate paint can be carried out as the third invention of the proposed group, representing a part of the method according to the first invention containing only operations involving the finished material separately manufactured product in the form of serpentinite cake.

The method according to the copyright certificate [5], in which a silicate block containing solid soluble glass is used as the starting material, is closest to the method for producing silicate paint according to the third invention of the proposed group.

This proposed method is inherent in all types of technical result, characteristic of the first invention of the proposed group, due to the above properties of the resulting paint and the peculiarities of the implementation of its second stage, in particular the possibility of carrying out this stage at normal temperature and pressure. Along with this, the possibility of obtaining silicate paint according to the third invention, i.e. using ready-made serpentinite cake, allows you to implement this process regardless of obtaining the cake itself both in time and geographically, geographically, creating the appropriate technological advantages and eliminating the difficulties that may arise during the implementation of the "end-to-end" process.

The method of producing silicate paint according to the third proposed invention, as well as the closest known method to it, includes grinding a product containing solid soluble glass, and combining the result of grinding this product with a liquid phase in the form of water.

To achieve the above technical result in the proposed method according to the third invention, in contrast to the closest known to it, as a product containing solid soluble glass, use the serpentinite sinter obtained in accordance with the second invention of the proposed group in the form of solid lumps or granules. Said solid lumps are subjected to said grinding after their preliminary crushing or granules. In this case, the combination of the grinding result of crushed lumps or granules with the liquid phase in the form of water is carried out directly in the grinding process, carrying it out in a ball mill with water. Water is added prior to the acquisition of the paint consistency product obtained during the grinding process.

The inventions of the proposed group are illustrated by examples.

During the experimental implementation of the inventions, serpentinite material was used, the data on the chemical composition (wt.%) Of two samples of which without indicating the water content are given in table 1.

Examples are presented in tables 2 and 3 with data on the substances used, the parameters of the technological conditions, the intermediate and final results of the experimental implementation of the method according to the first invention of the proposed group, including, as described above, as parts, the method according to the second invention and the method according to the third invention. The end of the method according to the second invention and the beginning of the method according to the third invention correspond to the lines "Sintered mass for grinding" of table 2 and table 3.

In the left column of each of tables 2 and 3 are the names of substances, operating parameters and other quantitative indicators characterizing the conditions of the method, and in the cells under the number of each of the examples - the corresponding quantitative values. The conditions of the two groups of examples (1a-10a, table 2 and 16-106, table 3) differ in the amount of water used during grinding.

In laboratory conditions, for the preparation of serpentine-alkali batch, an alkali solution was previously prepared in a heat-resistant container with a minimum amount of water sufficient to dissolve the taken amount of alkali, as determined by the solubility tables. This solution was poured into a plastic container with serpentinite powder and mixed thoroughly, gradually adding water until the total amount indicated for each of the examples in Tables 2 and 3 was reached. In all cases a homogeneous pasty mass was obtained.

With the help of the NORMIT D batcher in execution for work with an aggressive environment, this mass was dosed. In this case, the dosage parameters were selected to obtain portions in the form of blanks of granules weighing 1 and 5 g (see tables 2 and 3), which had sizes of 5-10 mm.

Fusion (sintering) of the pellet blanks was carried out in a laboratory furnace PL 20 / 12.5 at a temperature of 120 or 240 ° C (see tables 2 and 3) until they were cured.

After curing, the obtained pellets of sinter in the same amount (650 g) for all examples, without crushing, were poured into a 3 L laboratory ball mill with the addition of water in an amount of 850 or 1350 g (see tables 2 and 3). At the end of grinding, which lasted 5-6 hours, in all cases the product was obtained in the form of paint.

Each of the obtained paint samples was stored in a closed plastic bucket, periodically opening it for the manufacture of colorings and quality control of the paint. After two years of storage, no paint changes were noted. After three years of storage, the beginning of thickening of the paint was noticed.

Comparative characteristics of the production features, properties and cost of known silicate paints and paints produced by the proposed invention are shown in table 4.
