All three emulsifiers for hydraulic concentrates comprise hardly biodegradable derivatives of alkylphenols and their sulfonates and they do not make it possible to use non-toxic corrosion inhibitors and stabilizing-buffering additives.
Emulsifiers from the above patent documents are intended for specific compositions of oil concentrates which differ in use (mine water, soft/hard, with high/lower NaCl content) and obtainable working concentration of a fire-resistant hydraulic fluid (from 2% to 5 %). For each of those emulsifiers there is provided a specifically developed corrosion inhibitor in the form of toxic sodium nitrite, ecologically disadvantageous salts of boric acid or an organic corrosion inhibitor with limited functionality (it fails crevice corrosion test). The object of the present invention was to develop a universal emulsifier for the manufacturing of biodegradable concentrates used in the production of fire-resistant hydraulic fluids of HFAE and HFAS type having a concentration of 0.5 - 4 % for hydraulic systems of mechanized linings and individually or centrally supplied hydraulic props operating in underground mining excavations of hard coal, potassium salts and copper ores, which emulsifier would make it possible to use non-toxic corrosion inhibitors, ecologically safe and effective for various types of corrosion, and to use buffering agents and stabilizers without a negative effect on the stability of emulsifiable concentrates within a broad range of mineral oil content, and which emulsifier would use standard waters having a hardness of up to approximately 40 °N.
It has been found out unexpectedly that with a suitable selection of anionic and nonionic components of an emulsifier it is possible to prepare a universal emulsifying agent for concentrates of fire-resistant hydraulic fluids of HFAE and HFAS type having a concentration of 0.5% to 4%, used in hydraulic systems of mechanized linings and in individually or centrally supplied hydraulic props operating in underground mining excavations of hard coal, potassium salts and copper ores, which agent is characterized by a wide range of possible uses of base oil and mine water used to prepare fire-resistant hydraulic fluids. Adding organic salts and inorganic acids as buffering agents to the content of an emulsifier makes it possible to meet the requirements of crevice corrosion resistance test. The selection of emulsifier components:
• ethoxylated fatty alcohol having 10-18 carbon atoms in the hydrocarbon chain, which is a cosurfactant,
• ethoxylated mixture of unsaturated fatty acids triglycerides and unsaturated alpha- hydroxy fatty acids triglycerides, which is a basic nonionic surfactant,

· ethoxylated unsaturated fatty amine having 12-18 carbon atoms in the hydrocarbon chain, which is an additional nonionic surfactant having high HLB, • sodium salt of the sulfate of the ethoxylated with 2 moles of ethylene oxide fatty alcohol having 10-18 carbon atoms in the hydrocarbon chain, which is a basic anionic surfactant,
• alkylbenzene sulfonic acids having 8-10 carbon atoms in the linear and/or branched hydrocarbon chain, which are an additional anionic surfactant,
• N-oleoyl sarcosine acid, which is a basic element of a complex corrosion inhibitor,
• monoethanolamine, which is a basic element of a complex corrosion inhibitor,
• dipropylene glycol, which is a solubilizer stabilizing the viscosity of a
microemulsifiable concentrate,
• aqueous sodium cumenesulphonate solution, which is a hydrotropic component
enabling effective combination of surfactants of different nature,
• citric acid and 4 parts by mass of potassium carbonate, being components of the
stabilizer and the buffering agent,
• sodium gluconate, which is an supplementary ferrous metals corrosion inhibitor
having buffering properties,
• cyclohexylamine carbonate, which is an auxiliary steel corrosion inhibitor,
• water being the carrier/solvent of the composition,
• a commercial biocide, a non-ferrous metal passivator and a defoamer,
and selection of proportions of the above components made it possible to obtain a universal emulsifying agent for concentrates of fire-resistant hydraulic fluids of HFAE and HFAS type.
