Problems solved by technology

Although this method can provide a method for preparing a superhydrophobic / oleophilic oil-water separation membrane, concentrated nitric acid is needed in the intermediate process, which has certain safety hazards, and the preparation time is long, the steps are cumbersome, and the carrier used is metal. Net, metal material modification cost is high, and it is easy to be polluted by residual oil, and the service life is uncontrollable

preparation example Construction

[0017]The preparation method of the paint phenolic water separation film provided by the present invention includes the following steps:

[0018]Painted phenol solution is formulated with ethanol as a solvent;

[0019]Soak the cotton fabric substrate in the prepared lacquerol solution;

[0020]The soaked cotton fabric substrate was taken out, and the drying treatment was carried out to give the painthenol water separation membrane.

[0021]It can be seen from the above description, the advantageous effect of the present invention is that the cotton fabric substrate is modified by lacquerphenol, and the lacquer is coated on the surface of the cotton fabric substrate by solution impregnation method, and the surface energy of the cotton fabric substrate is reduced. The hydroxyl group on the cotton fabric substrate can be strongly complexed with lacquer, but also because the painthenol has a long side chain of hydrophobic properties, increases the hydrophobic effect of the cotton fabric substrate, ...

Embodiment 1

[0042]The solvent was prepared with ethanol as a solvent; the non-woven fabric was subjected to ultrasonic treatment in acetone for 15 min, dried into distilled water for 15 min, dried, and then placed in 0.01 mol / In the hydrochloric acid solution of L, then washed out of distilled water until neutral, then dried; a pre-treated nonwoven fabric was soaked in a phenolic solution of 60 mg / ml, and heating treatment and stirring treatment, said The heating temperature of the heat treatment was 50 ° C, the time was 24 h; the soaked nonwoven fabric was taken out, and the drying treatment was carried out at 120 ° C, and the time was 4 h, which obtained the paint-phenolic water separation film of the nonwoven fabric. .

Embodiment 2

[0044]Have a paint-phenol solution with ethanol as a solvent; the bio-oil and stains of the surface of the non-woven fabric were removed, and the obtained nonwoven fabric was soaked in a 40 mg / ml paint phenol solution, and the soaking nonwoven fabric was taken out. As in the oven, the drying treatment, the drying treatment, and the solidification treatment of the drying treatment is obtained by drying treatment, and the lacquer water separation film is obtained by the nonwoven fabric.

Abstract

The invention discloses a method for preparing an urushiol oil-water separation membrane, which belongs to the technical field of oil-water separation. The method for preparing the urushiol oil-water separation membrane comprises: preparing an urushiol solution with ethanol as a solvent, soaking a cotton fabric base material in the In the obtained urushiol solution, the soaked cotton fabric base material is taken out and dried to obtain the urushiol oil-water separation membrane. The preparation method of a urushiol oil-water separation membrane provided by the invention can prepare a variety of urushiol oil-water separation membranes for oil-water separation in one step. Water droplets cannot wet the surface of the oil-water separation membrane, and oil droplets can pass through smoothly, making the paint The phenolic oil-water separation membrane has hydrophobic and lipophilic properties; the whole preparation process is simple and fast, does not contain fluorine elements, the raw materials are green and pollution-free, and the cotton fabric has a wide range of sources, low price, low preparation cost, good mechanical stability, and good separation effect.

Description

Technical field[0001]The present invention belongs to the field of oil and water separation, and more particularly to a method for preparing a painthenol water separation membrane.Background technique[0002]Water is the necessary resources that maintain human survival. With the exacerbation of human activities and the rapid economic and social development, the situation facing water resources is becoming more severe, the water crisis characterized by tension, water pollution and flood disasters are become human. An important constraint for sustainable development. Among them, the fuel-free wastewater disclosed in sea crude oil and the oil-containing wastewater emissions in the production and life, which hinders the cyclic utilization of water resources. For oil-containing, traditional treatment methods include thermochemical treatment, microwave treatment, swirl separation method, and ultrasonic breast milk, and some physical law such as gravity separation, centrifugal separation, et...
