However, the molecular weight of the product obtained in this way is reduced by more than one-third, which greatly reduces the product quality, and the product property is unstable, and the filtration ratio exceeds the standard; at the same time, the drying time is long, the energy consumption is high, the production environment is poor, the labor intensity of the workers is high, and the production efficiency is low. Very low, unable to achieve large-scale continuous production

Embodiment 1
[0023] High molecular polymer lubricating oil dispersing aid of the present invention, its batching weight percent is composed of:
[0029] Preparation method: Add kerosene, C6-C18 alkyl polyoxyethylene ether sulfate, stearic acid, C2-C8 fatty alcohol, and C6-C18 alkyl polyglucoside into the reaction kettle and stir for 4 hours, then pressurize and spray The liquid becomes a columnar fluid stream, and the frictional contact between the fluid streams makes the liquid fully mixed.
Embodiment 2
[0031] High molecular polymer lubricating oil dispersing aid of the present invention, its batching weight percent is composed of:
[0032] Light diesel 76%
[0033] Alkyl Sulfate 7%
[0034] Nonylphenol ethoxylate 3%
[0035] Glycerin 8%
[0036] Ethylene glycol methyl ether 6%.
[0037] Preparation method: Add light diesel oil, alkyl sulfate, nonylphenol polyoxyethylene ether, glycerin, and ethylene glycol methyl ether into the reaction kettle and stir for 5 hours, and then pressurize and spray the liquid into a columnar fluid stream. The frictional contact between the fluid streams makes the liquids thoroughly mixed.
Embodiment 3
[0039] High molecular polymer lubricating oil dispersing aid of the present invention, its batching weight percent is composed of:
[0040] Hydrogenated Oil 79%
[0041] Fatty acid polyoxyethylene ether 6%
[0042] Palmitic Acid 2%
[0043] Diethylene glycol ether 8%
[0044] C6-C18 Alkyl Betaines 5%.
[0045] Preparation method: add hydrogenated oil, fatty acid polyoxyethylene ether, palmitic acid, diethylene glycol ether, and C6-C18 alkyl betaine into the reaction kettle and stir for 6 hours, and then pressurize the injection to make the liquid into a columnar fluid Beams are produced by the frictional contact between the fluid streams to thoroughly mix the liquids.

Abstract
The invention relates to a polymer lubricating oil dispersing aid and its scientific, reasonable, simple and easy preparation method, which is mainly used for the lubrication of rubber block cutting in the production process of polymer polyacrylamide, and the weight of ingredients is 100 Grouped into: 75-83% light oil, 5-8% emulsifier, 2-3% stabilizer, 7-8% solubilizer and 3-6% surfactant; add various ingredients to the reaction kettle Stir in medium for 3 to 6 hours, and then pressurize the jet to make the liquid into a columnar fluid beam, and the frictional contact between the fluid beams makes the liquid fully mixed. Adding it to the polymerized polyacrylamide rubber block can make it cut into small rubber blocks quickly, and the small rubber blocks are continuously sent to the granulator by the screw conveyor for fine granulation, and can obtain particles with a particle size of about 3 mm. Small colloidal particles. The fast and effective cutting method ensures that the molecular weight does not decrease, and the obtained small colloidal particles are uniform and loose, have good fluidity, and are easy to dry.
Description
technical field [0001] The invention relates to a polymer lubricating oil dispersion aid and a preparation method thereof, which are mainly used for lubricating rubber block cutting in the production process of polymer polyacrylamide. Background technique [0002] High molecular polymer polyacrylamide has various characteristics such as flocculation, thickening, drag reduction, adhesion, stable colloid, film formation and scale inhibition, and is widely used in important industries such as papermaking, mining, coal washing, metallurgy, environmental protection, and oil exploration. Sector, is an important chemical for water treatment. It plays an important role in improving production efficiency and product quality, especially as the most effective tertiary oil recovery agent, it has been widely used in the world's petroleum industry and has become an important means of improving oil recovery. Significant economic benefits. [0003] The polymerized polyacrylamide block con...
