preparation example Construction

[0050] The preparation method of the melamine-based sponge that is used to absorb floating oil on the water surface of the embodiment of the present invention may further comprise the steps:

[0051] (1) Pretreatment: the melamine-based sponge is ultrasonically cleaned in absolute ethanol and deionized water, and then dried;

[0052] (2) Roughening: the pretreated melamine-based sponge is placed in an aqueous cobalt compound solution, and at room temperature, an oxidant solution is added to the cobalt compound aqueous solution while stirring, and the melamine-based sponge is taken out after 20-30 minutes and dried;

[0053] (3) Hydrophobic modification: immerse the roughened melamine-based sponge in the hydrophobic modification reagent, and stir while soaking; after soaking for 20-30 minutes, take it out and dry it to obtain a melamine-based sponge for absorbing slick oil on the water surface.

[0054] The sponge is used to prepare superhydrophobic and lipophilic materials, an...

Embodiment 1

[0065] The melamine-based sponge was ultrasonically washed three times in absolute ethanol and distilled water and dried, then immersed in Co(NO 3 ) 2 In the aqueous solution, at room temperature, add the oxidant solution while stirring, take it out and dry it after the reaction is complete; After drying, the melamine-based sponge for absorbing floating oil on the water surface is obtained.

Abstract

The invention relates to melamine-based sponge for absorbing oil slick and a preparation method thereof. The preparation method includes the following steps of pretreatment: putting melamine-based sponge in absolute ethyl alcohol and deionized water for ultrasonic cleaning prior to drying; roughening: putting the pretreated melamine-based sponge in cobalt compound water solution, adding oxidant solution into cobalt compound water solution with stirring at room temperature, and after reaction, taking out and drying the melamine-based sponge; hydrophobic modification: soaking the roughened melamine-based sponge into hydrophobic modified reagent with stirring; after soaking, taking out the soaked melamine-based sponge prior to drying to obtain the melamine-based sponge for absorbing oil slick. The melamine-based sponge for absorbing oil slick is simple preparation method, mild in reaction condition, easily available in raw material, low in cost, high in oil absorption rate and good in reusability.

Description

technical field [0001] The invention relates to the technical field of functional materials, in particular to a melamine-based sponge for absorbing floating oil on water surfaces and a preparation method thereof. Background technique [0002] The technical background related to the present invention will be described below, but these descriptions do not necessarily constitute the prior art of the present invention. [0003] Fishing boats in the fishing boat mooring area will leak oil during refueling and maintenance. If the leaked oil is not treated in time, it will cover the water surface. On the one hand, it will affect the surrounding water quality and cause the water quality to decline. On the other hand, it will cover the The oil on the water surface will affect the dissolved oxygen content in the water body, and pose a hazard to the growth of aquatic organisms in the water body. [0004] Traditional water surface oil pollution treatment solutions include: biodegradati...
