(54) PREVENTIVE MEANS

one

The invention relates to prophylactic agents used to process transportation equipment in order to prevent wet rocks from sticking, losses from blowing loose materials during carriage in open wagons and for dust removal on quarry roads.

A prophylactic agent of petroleum origin is known - fuel oil used to combat. dust MH.

However, the high temperature of solidification of fuel oil and viscosity require its heating during storage and application on unpaved roads.

It is also known a prophylactic agent consisting of%: an extract for the selective purification of an oil fraction 280-460 C 70-94, a product of thermal refining (cracking the residue of sour oils) 2-10; tar oil sulfur 2-10; Asphalt sulfur oil 2-10.

The prophylactic agent is used to prevent moisture rocks from sticking to transport equipment, preventing losses from

blowing of bulk materials during gazing in gondola cars, as well as preventing dust formation on the roads of open pit G2.

The disadvantage of this tool is that it does not possess the necessary adhesive properties, and its production at the present stage of development of the oil refining industry is excluded due to the lack of thermal cracking units in the plant design, in addition, the tool is fire hazardous. 5 The purpose of the invention is to increase the service life and reduce the fire hazard of the product.

The goal is achieved by the fact that a known agent contains as oxidized asphalt or tar or a mixture of tar with asphalt as a thermal oil refining product, in the following ratio of components, wt.%:

oxidized asphalt

or tar, or a mixture

tar, with asphalt 2-15

Tar sulphurous. Neftey4-20

Sulfur oil asphalt 2-10 Selective oil purification extract Else Increasing or decreasing the concentrations of reagents impairs the quality of the product.

The tool is prepared by mixing the components within the specified limits.
