The disadvantage of the above-mentioned composition is insufficient resistance to aggressive media, in particular alkaline and acid (NaOH, KOH, HCl, H2SO4H2S, HNO3), and the use of scarce raw materials (polyvinyl butyral). Describes the use of alkylresorcinol epoxy-novolak resin with hardener for isolation and crepe is placed boreholes (A.S. 486129, USSR, EU 33/138, BI No. 36, 1975). The disadvantage of this technical solution is the lack of stability of the composition to the effects of reservoir fluids at elevated temperatures and aggressive environments, primarily alkaline and acid. A method of obtaining a modified epoxy resin for insulation and mounting holes (see Pat 2128677 of the Russian Federation, 1999), obtained by mixing a phenol-formaldehyde resin (epoxygenase resin, formalin, diethylene glycol, polyvinyl alcohol in the following ratio, wt.%:

A method of obtaining a composition for anti-corrosion coatings chemical and petrochemical equipment, pipelines, namely, that an active basis - waste production perforoperation, representing a mixture of marginal and non-marginal perforoperation, chlorohydrocarbons and osmol, pereshivayut with the solvent at a temperature of 70-90°C for 1.0 to 1.5 hours, then add the dioctylphthalate, chlorinated paraffin wax CP-470, EP is Xenoy resin ED-20 or ED-18, polyethylenepolyamine or polypropyleneimine, and stirred the mixture at a temperature of 75-85°for 1.5-2.0 hours, while the components of the mixture taken in the following ratio, wt.%:
2. A method of obtaining a composition for anti-corrosion coating according to claim 1, characterized in that the solvent charge mixture consisting of acetone or methyl ethyl ketone, butyl acetate or ethyl acetate, and toluene, in the following percentage ratio, wt.%: 10÷15:20÷25:60÷70. 3. A method of obtaining a composition for anti-corrosion coating according to claim 1, characterized in that the mixture of saturated and unsaturated of chloropeta, chlorohydrocarbons and osmol taken in the following ratio, wt.%: 62÷70:30÷38.
