FIELD: chemistry. ^ SUBSTANCE: present invention relates to emulsifying agents used to prepare water-in-oil or oil-in-water emulsions. Described is an emulsifying agent for producing an oil-in-water emulsion and a water-in-oil emulsion containing a mixture of a sodium salt of a copolymer of acrylic and methacrylic acid, sodium thiosulphate, sodium citrate, stearic acid, benzyl amine, colamine, engine oil, caustic soda and water, with the following ratio of components, wt %: sodium salt of a copolymer of acrylic and methacrylic acid (with 50:50 molar ratio of monomers) 2-4, sodium thiosulphate 3-9, sodium citrate 4-8, stearic acid 12-18, benzyl amine 3-8, colamine 2-6, engine oil 20-25, caustic soda 4-6, water being the balance. ^ EFFECT: obtaining a highly efficient emulsifying agent for producing roofing tar. ^ 6 ex |
