Abstract

The present invention relates to a superhydrophobic sponge body and a preparation method thereof. A purpose of the present invention is to mainly solve the problem of poor hydrophobic effect of the existing adsorption recovery material. The technical scheme of the present invention comprises a superhydrophobic sponge body and a preparation method thereof, wherein the superhydrophobic sponge body comprises a sponge body and a nanometer modifier, the sponge body is a melamine sponge or a polyurethane sponge, and the nanometer modifier preparation method comprises: dissolving a nanometer material in a hydrophobic organosilicon compound agent, and stirring until completely dissolving so as to obtain the nanometer modifier. With the technical scheme of the present invention, the problem in the prior art is well solved. The preparation method of the present invention can be used in the preparation of superhydrophobic sponge bodies.

Description

technical field [0001] The invention relates to a superhydrophobic sponge and a preparation method thereof. Background technique [0002] With the rapid economic growth, my country's oil consumption is increasing year by year, and its dependence on foreign countries is also expanding year by year. What followed was an increasing number of oil spill accidents on water, resulting in serious energy waste, environmental pollution and even hidden safety hazards. According to statistics, in recent years, the amount of oil spilled by ships and offshore drilling platforms in the coastal waters of my country has reached as high as 37,000 tons, of which there were 69 major oil spills of more than 50 tons, and the most serious oil spill was about 8,000 tons. Not only that, the oil spills caused by factors such as man-made and natural corrosion show an increasing trend year by year. All of these have further aggravated the shortage of oil resources in our country, severely restricted t...
