Organic-silicon-resin-base superhydrophobic oil-absorbing sponge and preparation method thereof

Abstract

A super-hydrophobic oil-absorbing sponge with a silicone resin as a matrix and a preparation method thereof relate to an oil-absorbing sponge. The mass ratio composition of the superhydrophobic oil-absorbing sponge with silicone resin as the matrix: matrix 3-10; titanium dioxide 5-20; p-xylene 6-20; dopant 150-100; dopant 26-20 20; the dopant 1 is an easily soluble small molecular crystal particle, and the dopant 2 is a non-volatile solvent compatible with p-xylene. Mix the matrix, a non-volatile solvent compatible with p-xylene, and p-xylene, then add soluble small molecular crystal particles and titanium dioxide, remove the superficial liquid after centrifugation, heat, then remove the cured resin, water and Acetone washes away easily soluble small molecular crystal particles, non-volatile solvents compatible with p-xylene and p-xylene, which is a super-hydrophobic oil-absorbing sponge based on silicone resin. Has good oil absorption performance.

Description

technical field [0001] The invention relates to an oil-absorbing sponge, in particular to a superhydrophobic oil-absorbing sponge with organic silicon resin as a matrix and a preparation method thereof. Background technique [0002] With the rapid growth of the global population, various pollutants including petroleum and toxic organic substances have appeared in many fields such as transportation, industry and daily life, and the pollution to the environment has also become increasingly serious. However, with the increase in the types and quantities of pollutants, traditional oil pollution treatment has been unable to carry out effective and targeted treatment. In 2010, a serious oil spill occurred in the Gulf of Mexico in the United States. However, during the months from the beginning of the oil well leak to the closure of the oil leak, people have not been able to effectively deal with the leaked crude oil. Its "burning oil" action has aggravated the emission of greenho...

However, with the increase in the types and quantities of pollutants, traditional oil pollution treatment has been unable to carry out effective and targeted treatment

In 2010, a serious oil spill occurred in the Gulf of Mexico in the United States. However, during the several months from the beginning of the oil well leak to the sealing of the oil leak, people have not been able to effectively deal with the leaked crude oil.

Although the modified sponge has a simple process and low cost, it has not greatly improved its oil absorption performance and cannot meet the use in special environments.
