FIELD: producing corrosion-resisting material with high protective properties, may be used in protection of oil and gas pipelines, as well as pipelines of various purpose against soil and electrochemical corrosion. SUBSTANCE: method is laid in the fact of changing technological regime of synthesis, and composition of raw materials. EFFECT: producing asphalt-resin oligomer of high protective properties, enhanced adhesion to metal, increased temperature of softening, that is increased mechanical strength and heat resistance. |
