Problems solved by technology

Traditional emulsified oil for hydraulic supports is produced from mineral oil, but petroleum is a non-renewable resource, and waste hydraulic oil is not easy to degrade and will pollute the environment
At present, non-ionic emulsifiers with relatively good emulsifying performance and cooling performance, environmental protection and safety are generally used, and various functional additives are added to synthesize emulsified oil, but they are still prone to corruption and deterioration, and the phenomenon of oil and soap separation will intensify when the emulsion is unstable. The wear and tear of the system affects the service life of the equipment and many other problems

Embodiment 1

[0013] The preparation method of the emulsion for hydraulic support in this embodiment is to add 67kg of water and 450kg of water-soluble castor oil into the reaction kettle, then add 80kg of boric acid and 5kg of sodium hydroxide, heat up to 90°C, and keep stirring for 30 minutes , then add 80kg of triethanolamine, keep stirring for 3 hours, add 8kg of Span-80 after the liquid is transparent, stir for 30 minutes, add 250kg of barium dinonylnaphthalenesulfonate and 15kg of zinc naphthenate , 20kg of dodecenyl succinic acid, 20kg of borax and 5kg of zinc dialkyl dithiophosphate, and continue to stir for 30 minutes to obtain the emulsion for the hydraulic support. Water-soluble castor oil is put into the reactor by 1 mass part of castor oil, 9 mass parts of ethylene glycol and 0.3 mass part of toluenesulfonic acid, heated up to 85°C, stirred for 3 hours, and rectified after condensation reaction. have to.

Embodiment 2

[0015] The preparation method of the emulsion for hydraulic support in this embodiment is to add 76kg of water and 420kg of water-soluble castor oil into the reaction kettle, then add 75kg of boric acid and 4kg of sodium hydroxide, heat up to 90°C, and keep stirring for 30 minutes , then add 75kg of triethanolamine, keep stirring for 3 hours, add 10kg of OP-10 after the liquid is transparent, stir for 30 minutes, add 280kg of barium dinonyl naphthalene sulfonate, 12kg of zinc naphthenate , 15kg of dodecenyl succinic acid, 25kg of borax and 8kg of zinc dialkyldithiophosphate, and continued to stir for 30 minutes to obtain the emulsion for the hydraulic support. Water-soluble castor oil is put into the reactor by 1 mass part of castor oil, 9.5 mass parts of ethylene glycol and 0.4 mass part of toluenesulfonic acid, heated up to 85°C, stirred for 3 hours, and rectified after condensation reaction. have to.

Embodiment 3

[0017] The preparation method of the emulsion for hydraulic support in this embodiment is to add 46kg of water and 480kg of water-soluble castor oil into the reaction kettle, then add 90kg of boric acid and 7kg of sodium hydroxide, heat up to 90°C, and keep stirring for 30 minutes , then add 90kg of triethanolamine, keep stirring for 3 hours, add 3kg of OP-10 and 3kg of Span-80 after the liquid is transparent, stir for 30 minutes, and add 220kg of barium dinonylnaphthalenesulfonate at 70°C, 18kg of zinc naphthenate, 25kg of dodecenylsuccinic acid, 15kg of borax and 3kg of zinc dialkyldithiophosphate, and continue stirring for 30 minutes to obtain an emulsion for hydraulic supports. Water-soluble castor oil is put into the reactor by 1 mass part of castor oil, 8.5 mass parts of ethylene glycol and 0.25 mass parts of toluenesulfonic acid, heated to 85 ° C, stirred for 3 hours, and rectified after condensation reaction. have to.

Abstract

The invention relates to an emulsion for a hydraulic support. The emulsion comprises the following components in percentage by weight: 40 to 50% of water soluble castor oil, 20 to 30% of barium dinonyl naphthalene sulfonate, 15 to 20% of compound additive, 0.5 to 2% of nonionic surfactant, 1 to 2% of zinc naphthenate, 1 to 3% of dodecenyl succinic acid, 1 to 3% of borax, 0.2 to 1% of zinc dialkyl dithiophosphate, and 4 to 8% of water. The compound additive is prepared by reactions among the following components in parts by weight: 35 to 45 parts of boric acid, 35 to 45 parts of triethanolamine, and 3 to 8 parts of sodium hydroxide. The emulsion has the advantages of excellent extreme pressure lubricating performance, wear resistant property, cooling property, antirust function, cleaning property, good stability, and resistance to corruption and deterioration.

Description

technical field [0001] The invention relates to emulsified oil for hydraulic supports and a preparation method thereof, belonging to the technical field of emulsified oil. Background technique [0002] The emulsified oil for hydraulic support is suitable for the power transmission medium of coal mine hydraulic support and external injection single hydraulic prop, which can effectively protect the hydraulic system and prolong its service life. The traditional emulsified oil for hydraulic supports is produced from mineral oil, but petroleum is a non-renewable resource, and waste hydraulic oil is not easy to degrade and will pollute the environment. At present, non-ionic emulsifiers with relatively good emulsifying performance and cooling performance, environmental protection and safety are generally used, and various functional additives are added to synthesize emulsified oil, but they are still prone to corruption and deterioration, and the phenomenon of oil and soap separati...
