The invention regarding temporary road quarry in mining quarrying, and also to prevent sticking, primerzanie and freezing wet rocks to the walls of the mining equipment in the mining industry, for example, to protect surfaces rolling against primerzanie and blowing bulk materials (coal, peat, and so on).

Known to be a preventive tool to combat dust, for example, on roads and quarries (ed. mon. The USSR 916527, From 09 To 3/22, 1982 ), containing cracking residue of sulfur crude oil, distillate fraction sulfur crudes intervals boiling 270-410oWith and Gidropress of cumene in the following ratios, wt.%:

Distillate fraction sulfur crudes intervals boiling 270-410oWITH - 39,5-59,7

Gidropress of cumene - 0,3-0,5

Cracking residue sulfur crudes - Rest

Known preventive tool has good plasmapause and particulate properties, but has a high pour point -15. .. -14oWith and may not be used in conditions of the North to prevent freezing of rocks, such as coking coal, and primerzanie them to the walls of the mining equipment.

The closest those who nd Universin-3" (ed. mon. The USSR 519467, 09 K 3/18, bull. 24, 1976) based on oil and heavy oil residue, and the oil it contains a light gas oil catalytic cracking, and as a heavy oil residue cracking residue thermal cracking during subsequent ratio of components, wt.%:

Light catalytic cracking gas oil - 90-98

Heavy oil residue - 2-10

The disadvantages of the known composition are low maintenance properties in the North against primerzanie and adhesion wet rocks, the limited resources of crude oil, as well as insufficient low temperature.

The present invention solves the technical problem of improving operational performance, reduce the pour point and extension resources of crude oil due to the inclusion in the composition of preventive lubricant wastes of petrochemical production.

This task is solved by the fact that preventive lubricant based heavy oil residue according to the invention further comprises a heating oil - VAT residue distillation pyrolysis resin or absorbent - waste production of monomers isoprene - 80,0...99,0

Heavy oil residue - 1,0...20,0

And as a heavy oil residue proposed composition contains a straight-run fuel oil.

Physico-chemical characteristics of straight-run fuel oil, furnace oil and adsorbent are presented in table. 1.

From table. 1 shows that the straight-run fuel oil has a high density (0,960 g/cm3, viscosity 7,35oWU at 80oWith 10,18 andoWU under 100oC) and a pour point of +20oC. Distinguishing feature is the high content of mechanical impurities of 0.15 wt.% and water (traces). To increase viscosity, adhesion and lubricity preventive lubricant in the base fraction - heating oil - VAT residue pyrolysis resin or absorbent - waste production of isoprene monomers of synthetic rubber was injected into the heavy oil residue as a straight - run fuel oil in an amount of from 1.0 to 20.0 wt.%.

"Hydrocarbon fuel" (waste production) is a mixture of hydrocarbon, C8and above aliphatic and aromatic series /THE 5192-429-05 742686-96/. The fuel is obtained from the processing of pyrolysis tar distillation products rectificate the heavy hydrocarbon resins and other needs of industrial enterprises. The absorbent material is a combustible liquid, a mixture of saturated hydrocarbon, aliphatic and aromatic series, practically insoluble in water /TU 38. 103349-85/.

From table. 1 shows that heating oil has a density 0,986 g/cm3, lightweight content of light fractions, wikipaedia to 10 and 50% fractional composition, low pour point of minus 65oC. the Absorbent material has a density 0,892 g/cm3the pour point -71oC. This is due to the characteristics of the hydrocarbon composition (see table. 2). As can be seen from the presented data, low pour point fuel and adsorbent due to the almost complete absence of paraffin hydrocarbons 3,62% vol. for furnace fuel and 0% vol. for absorbent and low content of cycloparaffins 7,51 about. % for heating oil and 12,37% vol. for absorbent with a high content of alkyl benzenes 23,52% vol. for furnace fuel and 62,87% vol. for absorbent and tetralines 26,61 about. % for furnace fuel, 13,31% vol. for absorbent, and the presence of bicyclic, naphthenic, 14,91% vol. for furnace fuel and 18,14 about. % for absorbent and tricyclic aromatic hydrocarbons of 2.26% vol. for furnace fuel and 0.51% for absorbent.

Scheme Polytechnik fuel or absorbent, drain pump 2 for pumping fuel stove or absorbent, the receiving tank 3, tank 4 with straight-run fuel oil, drain pump 5 fuel oil receiving tank 6 fuel oil with steam heating 7. The temperature of the oil should not be below 80oWith, dosing pumps 8 and 9 for furnace fuel or absorbent and straight-run fuel oil, respectively, of the mixing tank 10, a pump 11 for circulation, pumping and filling reservoirs for the reception of a commodity product.

Preventive lubricating material was obtained as follows.

Heating oil - VAT residue pyrolysis resin or absorbent - waste production of isoprene monomers of synthetic rubber from the tank 1 by the pump 2 is pumped into the tank 3, and the straight-run fuel oil from the tank 4 by the pump 5 is pumped into a receiving tank 6 with a steam heating 7. Prepared components pumps dosing pumps 8 and 9 in the mixing tank 10.

The injection is performed in the following sequence. Start dosing pump 8 to a certain capacity for pumping fuel stove or absorbent. After the release of the operating mode starts the dosing pump 9 for pumping of straight-run fuel oil. Proizvodnja pumping VAT residue stop the dosing pump 9, then stop the pump 8. Produce samples from the upper, middle and lower layers preventive lubricating material in the mixing tank 10. Then carry out analysis of samples for quality. In the case of obtaining under stirring in a mixing tank 10 heterogeneous mixtures produce circulation of the circulating pump 11. The duration of the circulation should be such that through the pump 11 has passed the liquid in a quantity equal to the volume of the prepared mixture. After circulation again carry out the analysis of samples taken by the layers. When obtaining a homogeneous mixture is discharged commodity passport ready commercial product - preventive lubricant.

Examples of obtaining the proposed preventive lubricant.

Example 1. In the mixing tank 10 dosing pump serves 8 80,0 wt. % fuel stove or absorbent, and the pump 9 serves 20 wt.% straight-run fuel oil, preheated to a temperature of 80oC, stirred until a homogeneous mass. Produce analysis of selected samples. The quality of the received preventive material is presented in a table. 3.

Example 2 same as example 1. Only the or absorbent and 1.0 straight-run fuel oil.

The quality of the resulting lubricant is also presented in the table. 3.

The other examples and the quality of the resulting lubricant in comparison with the prototype are also presented in table. 3.

The obtained lubricating material is a thin oily liquid dark brown color, having a lower pour point, high lubricating ability in comparison with the prototype, and use its structure as a basic fraction of waste petrochemical production will significantly expand the resource base to obtain preventive lubricants, high performance, allowing their use for the prevention and freezing of coking coal at low temperatures during transportation, roads and quarries.

Preventive lubricant based heavy oil residue, characterized in that it further comprises a heating oil - VAT residue distillation pyrolysis resin or absorbent - waste production of isoprene monomer to synthetic rubber and as a heavy oil residue it contains straight-run fuel oil p is th - 1,0-20,0
