specific Embodiment approach 1

[0042] Specific embodiment one: the present embodiment takes corn oil as an example to produce emulsified oil for hydraulic supports; its preparation method is carried out according to the following steps:

[0043] Step 1. Mix 150kg corn oil and 99kg naphthenic acid, start stirring at 70r / min when the temperature rises to 75°C, add 99kg of lye, and then carry out saponification reaction at 100°C until the pH value is 8.0-8.5. ;

[0044] Step 2, then add 99kg rosin;

[0045] Step 3. When the rosin is completely dissolved, add 461 kg of corn oil and stir at 70 r / min for 10 min at 125 ° C;

[0046] Step 4, then adjust the temperature to be 80°C, then add 99kg sodium petroleum sulfonate, 29kg triethanolamine and 5kg benzotriazole;

[0047] Step 5. Then adjust the temperature at 80°C, then add 29kg of water, stir at 70r / min for 15min, cool down to 50°C, and obtain a reddish-brown transparent liquid. After testing, the viscosity is ≤100㎜ 2 / s (40°C), the pH value is 7.5-9.0, the ...

specific Embodiment approach 2

[0051] Specific embodiment two: the present embodiment takes rapeseed oil as an example to produce emulsified oil for hydraulic support; its preparation method is carried out according to the following steps:

[0052] Step 1. Mix 150kg rapeseed oil and 99kg naphthenic acid, start stirring at a speed of 75r / min when the temperature rises to 80°C, add 99kg of lye, and then carry out saponification reaction at 120°C until the pH value is 8.0-8.5 Finish;

[0053] Step 2, then add 99kg rosin;

[0054] Step 3. When the rosin is completely dissolved, add 461kg of rapeseed oil and stir for 10min at a speed of 75r / min at 130°C;

Abstract

The invention provides a preparation method of an emulsified oil for a hydraulic support and belongs to the field of a high-moisture content hydraulic liquid. The preparation method provided by the invention is used for solving the technical problems of non-renewability resources and failure in degradation of the existing emulsified oil (high-moisture content hydraulic liquid) for the hydraulic support. The method comprises the following steps of: 1, mixing a plant oil with naphthenic acid, increasing the temperature to 60 to 80 DEG C, and then stirring, adding an alkaline liquid, and carrying out a saponification reaction until the pH value is 8.0 to 8.5; 2, adding rosin; 3, after the rosin is completely dissolved, adding the plant oil and stirring at 120 to 130 DEG C; 4, adjusting the temperature to 80 DEG C, and adding petroleum sodium sulfonate, triethanolamine and benzotriazole; and 5, adjusting the temperature to the range from 70 to 80 DEG C, adding water and stirring, reducing the temperature to below 50 DEG C, and filtering after passing a test, thereby obtaining the emulsified oil for the hydraulic support. The plant oil adopted by the invention is renewable; in other words, the raw material is inexhaustible. Besides, the product obtained by the preparation method provided by the invention is environment-friendly, easy to degrade, free of pollution to the environment, and simple in aftertreatment.

Description

technical field [0001] The invention belongs to the field of high water content hydraulic fluid and specifically discloses a preparation method of emulsified oil (high water content hydraulic fluid) for hydraulic supports. 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. [0003] The traditional emulsified oil (high water-containing hydraulic fluid) for hydraulic supports is produced from mineral oil, which has two technical problems: first, mineral oil is extracted from petroleum, which is a non-renewable resource. will run out. Second, mineral oil is an organic chemical raw material and is not easy to degrade. Waste hydraulic oil pollutes the environment, especially groundwater. Contents of the invention [0004] The invention aims to solve the te...
