METHOD OF PRODUCING COMPOSITION FOR ANTICORROSION COATING CHEMICAL AND PETROCHEMICAL EQUIPMENT, PIPES Russian patent published in 2009 - IPC C09D5/08 C09D163/02 

FIELD: chemistry.

SUBSTANCE: an active base - wastes from production of perchlorocarbons, which is a mixture of saturated and unsaturated perchlorocarbons, chlorohydrocarbons and resinous wood are mixed with a solvent at 70-90°C temperature for 1.0-1.5 hours. Dioctylphthalate, "ХП-470" chloroparaffins, epoxy resin "ЭД-20" or "ЭД-18", polyethylenepolyamines or polypropylenepolyamines are then added. The mixture is then stirred at 75-85°C for 1.5-2.0 hours. The components of the composition are taken in the following ratio, in wt %: 40-50 of the above mentioned active base, 0.4-1.6 dioctylphthalate, 0.1-0.4 "ХП-470" chloroparaffins, 2.0-4.5 epoxy resin "ЭД-20" or "ЭД-18", 0.2-1.4 polyethylenepolyamines or polypropylenepolyamines, and solvent constitutes the rest.

EFFECT: increased resistance to effect of aggressive media and simplification of preparation of the composition.
