Embodiment 1

[0037] Add 100g of quartz sand with a particle size of 0.074-0.085mm into the sand mixer and stir, then add 10g of fluorine-modified epoxy resin to the quartz sand and stir evenly to form a mixture, so that the fluorine-modified epoxy resin is mixed with the quartz sand Cover the surface with a film, then add 0.1g of silicon micropowder with a particle size of 0.015-0.020 microns, and stir evenly to make the silicon micropowder adhere to the fluorine-modified epoxy resin, then add 7g of curing agent phenalkamine and stir evenly to promote fluorine For the curing of the modified epoxy resin, add 2g of dispersant paraffin before the above-mentioned mixture is agglomerated and continue to stir to reduce adhesion. After the normal temperature curing is complete, the obtained mixture is crushed and sieved to obtain coated particles, and the coated particles are calcined at 400-600° C. for 2 minutes to form a micro-nano composite structure on the surface of the coated particles to fo...

Embodiment 2

[0039] Add 100g of ceramsite with a particle size of 0.085-1.18mm into the sand mixer and stir, then add 1g of silicon-modified epoxy resin to the ceramsite and stir evenly to form a mixture, so that the silicon-modified epoxy resin is mixed in the ceramsite Surface coating, then add 0.4g of alumina powder with a particle size of 0.015-0.020 microns, and stir evenly to make the alumina powder adhere to the silicon-modified epoxy resin, then add 0.5g of curing agent cycloaliphatic amine and stir evenly , to promote the curing of silicon-modified epoxy resin, add 0.5g of dispersant calcium-based grease before the above-mentioned mixture is agglomerated and continue to stir to reduce adhesion. After the normal temperature curing is complete, the obtained mixture is crushed and sieved to obtain coated particles, and the coated particles are calcined at 400-600° C. for 2 minutes to form a micro-nano composite structure on the surface of the coated particles to form the final product...

Embodiment 3

[0041]Add 100g of gravel with a particle size of 0.074-0.085mm into the sand mixer and stir, then add 30g of polysulfide rubber modified epoxy resin (the mass ratio of epoxy resin: polysulfide rubber is 5:1) to the gravel and stir Uniformly form the mixture, make the polysulfide rubber modified epoxy resin film on the surface of the gravel, then add 9g of a mixture of microsilica powder and alumina powder with a particle size of 0.015-0.020 microns, and stir evenly to make the microsilica powder and alumina powder The powder adheres to the polysulfide rubber modified epoxy resin, then add 25g curing agent aliphatic amine and stir evenly to promote the curing of the polysulfide rubber modified epoxy resin, and then add 0.3g before the above mixture is agglomerated Dispersant lithium-based grease continues to stir to reduce sticking. After the normal temperature curing is complete, the obtained mixture is crushed and sieved to obtain coated particles, and the coated particles ar...

Abstract

The invention discloses an oil-water separation material and a preparation method thereof. The oil-water separation material comprises aggregates and an oleophylic and hydrophobic resin film coating the aggregates, wherein the oleophylic and hydrophobic resin film is formed by one or more of fluorine, silicon and sulfur. The oil-water separation material has a micro-nano composite structure. The oil-water separation material further comprises an additive, wherein the grain diameter of the additive is 0.015-0.020 microns, and the mass ratio of the additive to the oleophylic and hydrophobic resin film is equal to (1-50):100; and the additive can be silica powder and / or alumina powder. The oil-water separation material has super-hydrophobic and super-oleophylic performance, and has a good oil-water separation effect; and the oil-water separation material is prepared by a reactive film coating technique, the binding strength between the aggregates and the resin film is high, and thus the resin film is less prone to falling in use.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a porous oil-water separation material with superhydrophobicity and superoleophilicity. Background technique [0002] The free water contained in the oil not only affects the quality of the oil, but also the oily sewage discharged from urban and industrial production is a serious pollution source of the environment. Therefore, finding an economical, durable and efficient oil-water separation method is an urgent problem to be solved in industrial production and urban life . At present, oil-water separators with complex equipment and high energy consumption are widely used in the field of oil-water separation technology. Therefore, it is an important subject in the filtration industry to find a method that is both economical and practical, and can continuously remove water in the oil. [0003] Chinese patent document CN101586024A discloses a film-coated particle for oil r...
