Problems solved by technology

[0006] In order to overcome the problems of low oil-water selective adsorption performance, easy blockage of adsorption pores and short service life caused by the oil-water amphiphilic properties of organic polymer adsorption materials, especially when other solutions are difficult to work, and it is difficult to balance dehydration efficiency and selectivity, The invention provides a new solution, which can not only greatly improve the selective adsorption capacity of oil and water of the sodium polyacrylate adsorption resin material, but also ensure that the high-efficiency dehydration performance of the material itself has a slight impact, so that the comprehensive use of the material Enhanced performance and extended service life

Embodiment Construction

[0017] Specific implementation according to the appended figure 1 Follow the steps shown:

[0018] 1. Preparation steps of a series of adsorbent materials: add 60mL cyclohexane and 2mL cetyl alcohol phosphate into 6 flasks respectively, and pass nitrogen gas to drive out the oxygen in the bottles, and raise the temperature to 60°C to dissolve them. At the same time, 7.5g of acrylic acid was placed in 6 conical flasks, neutralized with a 41% NaOH solution to the acrylic acid monomer weight under cooling conditions, and 0.6% of the acrylic acid monomer weight was added to the conical flasks. Potassium sulfate is used as an initiator, and then respectively continue to add N, N'-methylenebisacrylamide with a weight of 0.04%, 0.06%, 0.08%, 0.09%, 0.10%, and 0.12% of acrylic acid monomers as a crosslinking agent, blowing Enter nitrogen, pour the mixed solution into the dropping funnel, drop the mixed monomer in the dropping funnel into the flask at a speed of 1-2dr / s, and then reac...

Abstract

The invention belongs to a method for improving oil-water adsorption selectivity of an oil adsorbing separating purifying dewatering material sodium polyacrylat. The method mainly consists of the following steps: (1) taking N, N'-Methylenebisacrylamide as a cross-linking agent, potassium persulphate as an initiator and cyclohexane as a continuous phase, adjusting the amount of the cross-linking agent, and employing inverse suspension polymerization to prepare a series of sodium polyacrylat dewatering resin materials; (2) respectively determining dewatering performance and oil-water adsorption selectivity of a series of the sodium polyacrylat dewatering resin materials; and (3) according to the performance data of a series of the sodium polyacrylat dewatering resin materials, drafting a curve map to determine optimum balance control amount of the cross-linking agent, and adopting the optimum balance control amount of the cross-linking agent to prepare an adsorptive resin material with high dewatering performance and high adsorption selectivity.

Description

technical field [0001] The invention belongs to the field of organic polymer materials and oil purification and separation, and its technical content relates to a method for improving the oil-water selective adsorption performance of sodium polyacrylate adsorption resin, an oil-liquid adsorption, separation, purification and dehydration material, especially the use of original technical means to improve the oil-water adsorption material Choose the method of adsorption capacity and service life. Background technique [0002] The development and application of adsorption separation materials is the core of oil purification technology based on adsorption. Sodium polyacrylate adsorption resin material is a new type of oil dehydration purification material. However, the oil-water amphiphilic properties of most resin materials will lead to competitive adsorption of oil-water molecules on the material interface, causing a large number of oil molecules to enter the adsorption pores...
