The invention relates to a preventive means to prevent freezing of wet rocks, their adhesion and primerzanie to the walls of the mining and transport equipment, to prevent dust formation on temporary roads, mining quarrying, and to protect surfaces rolling against primerzanie and blowing bulk materials such as coal, peat, etc.

Preventive tool is a thin oily liquid solvent-based and thickening additives of petroleum and petrochemical origin. When applying the liquid on the treated material, on its surface a thin film that prevents freezing, dust and blowing solids.

Prophylactic agent should have good wetting and adhesion with respect to the processed material, having a low pour point, available raw materials.

Prophylactic compositions for these purposes is widely known in the technique.

For example, in ed. St. USSR №519467 described composition, where the solvent used light catalytic cracking gas oil, and as a thickening additive heavy oil residue. The disadvantage is the limited R the resources of crude oil and not enough low pour point.

To address the problem of expanding the resource base on the basis of refined petroleum products aimed auth. St. USSR №749878. As a solvent it is proposed to use the clarified fraction and wash kerosene, gasoline fraction, a fraction obtained by deparaffinizing oil molecular sieves and distillate residue generated during the reforming process. As a thickening additive is a residue of pyrolysis oil. Despite the good performance characteristics, the use of distillate products of primary processing of oil has not solved the problem of creating an accessible resource base for the production of a prophylactic agent.

In the patents of the Russian Federation 2111228, 2132350 and 2155201 prophylactic receive on the basis of such petroleum products as kerosene, gas oil fractions of catalytic and thermal cracking and tars. As previous, and these solutions do not resolve the problem of shortage of constituent components.

More promising are the solutions for the creation of preventive means on the basis of waste production in the refining and petrochemical industry. Known prophylactic agent (patent RF №2196162), in which the problem of shortage of crude oil partially solved through the use of the solvent waste production - VAT residue production butyl and the butyl alcohols in further COBS), and as a thickening additive - straight-run fuel oil. The disadvantage of this solvent is its limited compatibility with the components of thickening additives and other solvents that may eventually lead to interfacial delamination of proforest and respectively to the deterioration of its quality or complete unfitness for use.

Closest to the claimed solution is a preventive tool, described in the patent of the Russian Federation No. 2190654, where the solvent used VAT residue processing resins pyrolysis or absorbent - waste production of isoprene monomer to synthetic rubber (hereinafter COPS). As a thickening additive, as in the previous case used straight-run fuel oil. This solvent compared with the previous has a higher solvent capacity, but the resources of this product are insufficient to satisfy all needs in this kind of components. Another disadvantage is the need of the use of straight-run fuel oil. Requires constant heating up to +80 C, which leads to additional energy cost, and complexity of the technology of production of a prophylactic. In addition, the known viscosity of the composition at temperatures below -20°With sharply increases, which leads to increased consumption, the preventive means and complicates the technology they use to produce a uniform coating.

The present invention solves the technical problem of further increasing raw material resources through the involvement of waste produced not only in refining and petrochemicals, but also other industries, in particular the coke.

Another objective of the present invention is to increase the flexibility of the production process prophylactic agent by using such a solvent, which would ensure the compatibility of the blend components of the solvent, both among themselves and with components of the thickening additive.

This task is solved in that a preventive tool against freezing, sticking and dust, loose materials, representing a mixture of a solvent and a thickening additive oil origin, in the solvent used VAT residue of coke production (KRCS) or by-products of the production of butadiene, isoprene, isobutylene, ethylene (hereinafter JAW) or their mixture in any combination with each other, the ratio of solvent and a thickening additive amounts, wt.%:

Solvent40-99,5
Thickening additive0,5-60

Another option prophylactic agent is using as the solvent bottoms of coke production (KRCS) or by-products of the production of butadiene, isoprene, isobutylene and ethylene (GO) or their mixtures with kovovymi remnants production pyropolymer, resin pyrolysis of benzene, ethylbenzene and styrene (COPS), as well as with kovovymi remnants production of butanol, Isobutanol, 2-ethylhexanoic acid, 2-ethylhexanol (COBS) in arbitrary combination with each other, the ratio of solvent and a thickening agent as in the first embodiment is, wt.%:

solvent40-99,5
thickening additive0,5-60

The solvent may additionally include a gas oil catalytic and thermal cracking, as well as the oil coking.

One of the basic requirements as a preventive measure is the flash point. To meet this requirement, the initial boiling point is used bottoms should not be below 160°C. Because the quality of the waste is not strictly regulated, then this indicator may have a lower value. In this case, the lighter fraction is distilled off. The rest of the rectification with the beginning of the boil 160°and above used for the preparation of a prophylactic agent in the solvent.

The other main ingredient of a prophylactic agent in both cases, the two which is a thickening additive oil origin.

As a thickening additive in both embodiments of the invention, a mixture comprising mineral oil and synthetic all kinds, waste oils, all types, oil sludge, oil residues and oil fuel, while the components of the thickening additive used in arbitrary combination with each other.

As oil residues are residues of all kinds, having a viscosity of up to 10 WU at 80°C.

As fuel oil, mainly used fuel derived from oil waste.

As shown by experimental data, any mixture of these components gives the desired result, if the solvent (option 1) or a mixture of solvents (option 2) is used KRCS and/or JAW.

The explanation for this probably lies in the properties of these products. Study of physico-chemical properties and hydrocarbon composition of these products (see table 1) show that they have a relatively high flash point (+85°) and good low-temperature properties (-65°). Hydrocarbon composition of the used solvents: KRCS, GO, COPS, KOBS is provided in Annex 1, 2, 3, 4. From the application 1, 2 shows that the KRCS and GO characterised by complete absence of paraffin compounds and at the same time a high content (at su the IU more than 70%) of aromatic hydrocarbons. This is due to the low pour point of these solvents and the possibility of mixing on the basis of various solvents and components thickening additives.

These distillation residues in sufficient amounts in the domestic petrochemical plants and as fuel is burned in furnaces to generate heat, and are also used for dilution of fuel oil and other needs of industrial enterprises.

Conducted by the applicant's analysis of the level of technology has allowed to establish that the analogs are characterized by the sets of characteristics is identical for all features of the declared options for prophylactic, are absent. Therefore, each of the claimed invention meets the condition of patentability "novelty".

The hallmark of the first and second variants of the invention is the use as solvents KRCS, GO alone (option 1), or in mixture with other solvents (option 2). However, the possibility of using these residues in a mixture with each other does not follow clearly from the existing level of knowledge. Moreover, the solvents having different hydrocarbon basis, usually by mixing prone to separation phases. Moreover, one cannot assume in advance about the possibility of mixing these poorly studied solvent is th, as petrochemical waste and by-product coke plants. Numerous studies have helped to identify available today waste such a "universal" source of raw materials, as KRCS, GO to obtain a preventive measure. Not only are these products themselves are excellent solvents with respect to thickening additives of different origin (option 1), but also promote compatibility with each other known solvents (option 2).

Therefore, both variants of the invention, in my opinion, correspond to the condition of patentability "inventive step".

Scheme for the proposed preventive means shown in the drawing and includes a reservoir 1 for the solvent (option 1), the reservoir 2 for the solvent (option 2), the tanks 3, 4 for thickening additives, tank mixing the starting components 5, product tank 6, the raw metering pumps 7 and 8, the pump for circulation and pump-down of a marketable product 9, trademarks pump 10.

Prophylactic obtained as follows. The solvent from the reservoir 1 in the first embodiment or from the tank 2 according to the second variant pump 7 with a given performance is injected into the reservoir mixing 5. After the pump outlet 7 in the specified mode, run the pump 8 for pumping thickening additive is C tanks 3, 4. The performance of the pumps 7 and 8 must be controlled to provide the desired ratio of components. 5-10 minutes before the end of injection solvent pump 7 is stopped. Produce samples from the upper, middle and lower layers of the reservoir mixing 5 and make it the analysis of the quality indicators. In the case of a heterogeneous mixture, produce a circulation pump 9. The duration of the circulation should be such that the pump 9 was twice the volume of the liquid in the tank mixing 5. After circulation produce re-sampling (in layers), after which the finished product is pumped into marketable tank 6, it is issued a passport and a prophylactic is sent to the consumer.

Examples of receiving prophylactic agent for option 1. Prophylactic agent is obtained by mixing 90% solvent - KRCS and 10% thickening additives (EP), which includes, in wt.%:

Example 17 (the prototype), where the solvent used VAT residue processing resins pyrolysis, as thickening additives - oil ratio (wt.%) accordingly, 90 and 10.

The quality of the product obtained in the above examples, are presented in table 2.

As can be seen from the table, as a preventive measure, obtained according to the invention, is not inferior to the quality known means (example 17 - prototype).

The optimal ratio of solvent and a thickening additive (wt.%) respectively 90 and 10. The change of this ratio (see examples 6, 7 for the 1st option and examples 13, 14 on the 2nd variant) leads to some deterioration in the performance characteristics (temperature solidification in the case of increasing the share of thickening additives or flash temperature, in the case of increasing the proportion of solvent). The ratio of solvent and ZV is selected based on the specific requirements of the applicant.

From the above examples also indicate that the quality of proforest almost no effect of the presence of certain components in the solvent, in the thickening additive, provided that the solvent is KRCS and/or JAW or in a mixture of solvents consisting of these products.

The absence of these components in a solvent (example 16) leads to stratification of the mixture, reducing the temperature is its freezing up -41° And regelation of the processed materials.

Thus, the main advantage of the present invention is the flexibility of the production process prophylactic agent. Thanks to the use of substances such as residual coke production and/or by-products of the production of butadiene, isoprene, isobutene, ethylene with one hand was found satisfying the needs of the production of raw source, on the other hand, it became possible for a mixture of various petroleum products and petrochemicals, and most importantly waste of their production and consumption. This circumstance not only expands and reduces the cost of raw materials the production of a prophylactic agent, but also improves the environment by recycling various industries.

The roadway ice covering suppressing reactant may additionally contain a fired limestone in amount of 3-5 mass % in terms of calcium oxide. The method of production a roadway ice cover suppressing reactant for a roadway covering slipperiness prevention provides for mixing of a component containing a magnesium compound, iced acetic acid and water, in the capacity of the component containing the magnesium compound is used brucite, the stirring is exercised in two stages: first they continuously agitate brucite with water and a part of iced acetic acid in a stoichiometric ratio at the temperature of 50-70°C within 50-80 minutes, then, not terminating mixing at the same temperature in the produced mix with pH=5-6 add the rest of ice acetic acid and then add potash in amount exceeding by 0.1 - 6 % the stoichiometric ratio and continue agitation till production of the roadway ice cover suppressing reactant - a solution with pH = 7-9.5 with the above indicated composition. The used roadway ice cover suppressing reactant has composition mentioned above. The technical result consists in - maintenance of the low temperature at the reactant usage, ensuring the passing ice covered roadways motor vehicles metal corrosion protection and at use as the airfield runways coatings - the corrosion protection of metals used in aircraft designs as well. The roadway coating treated with the reactant has a high coefficient of adhesion, that reduces the accident rate on the roadways.

EFFECT: the invention ensures, that the roadway coating treated with the reactant decreases the accident rate on the roadways.
