High molecular polymer lubricant oil dispersing auxiliary and method of producing the same

Abstract

The invention relates to a high molecular polymer lubricant dispersing aid and a preparation method thereof which is scientific, reasonable, simple and practicable. The dispersing aid is mainly used for the lubrication of rubber brick cutting in the production process of high molecular polymer polyacrylamide and comprises ingredients according to the percentage by weight: 75-83% of light weight oil, 5-8% of emulsifier, 2-3% of stabilizing agent and 7-8% of solubilizing additive and 3-6% of surface active agent. Various ingredients are added into a reaction kettle for being stirred for 3-6 hours, the liquid becomes cylindrical fluid bundles by pressuring and injection and then the friction type contact among fluid causes the fluid to be fully blended, thus the dispersing aid is prepared. The dispersing aid is added into the polymerized polyacrylamide rubber brick to cause that the polyacrylamide rubber brick is quickly cut into small rubber bricks which are continously sent into a pelleting machine for fine granulation by a screw conveyor, thus small colloidal particles with the diameter of about 3mm can be obtained. The fast and effective cutting method ensures that the molecular weight is not reduced, and the obtained small colloidal particles are uniform, unwound and easy to be dried and has good fluidity.

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...

Problems solved by technology

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
