Abstract

The invention provides a preparation method of a super-hydrophobic sponge material for oil-water separation, and relates to the field of oil-water separation materials. The preparation method comprises the following steps: mixing polyether silicone, polypropylene oxide glycol and methylbenzene, heating, adding isophorone diisocyanate and dibutyltin laurate, reacting for 5-10 h, adding gamma-aminopropyltrimethoxysilane into a mold, and curing the mold to form a semi-finished product A; coarsening the semi-finished product A, and freeze-drying the semi-finished product A to obtain a semi-finished product B; carrying out ultraviolet irradiation on the semi-finished product B, and immersing the semi-finished product B into a triethyl chlorosilane n-hexane solution to obtain a semi-finished product C; and loading nano-silica to obtain the super-hydrophobic sponge material finished product. The contact angle between the surface of the sponge material and water is larger than 150 DEG, the sponge material has super-hydrophobic performance, the contact angle is only slightly decreased after n-hexane is repeatedly absorbed for 10 times, the sponge material has excellent adsorption capacity for diesel oil with high viscosity, and the adsorption capacity is basically not decreased after repeated adsorption for multiple times.

Description

technical field

[0001] The invention relates to the field of oil-water separation materials, in particular to a preparation method of a superhydrophobic sponge material used for oil-water separation. Background technique

[0002] With the development of the economy, a large number of water sources polluted by organic matter or oil products are produced in modern society. The more typical ones are the frequent occurrence of oil spill pollution incidents in marine transportation in recent years. These polluted water sources have caused great damage to the ecological environment. Traditional treatment The methods of oil pollution of water sources are mainly divided into physical methods, chemical methods and biological methods. The physical treatment method has low efficiency and is greatly affected by the weather environment. When chemical and biological methods are used to treat oil-polluted water sources, a certain amount of chemical reagents are required for treatment, whic...
