Abstract

The invention relates to a method for preparing a hydrophobic porous oil-water separation material and belongs to the technical field of material processing. The method comprises the following steps:stirring and mixing sliced paraffin with liquid paraffin, performing water bath heating so as to obtain molten paraffin, weighing obsidian, pitchstone and perlite, performing ball-milling, screening so as to obtain ball-milling powder, putting the ball-milling powder and molybdenum disulfide into a quartz pipeline, sealing the quartz pipeline, vacuuming, performing heating, introducing argon intoa quartz tube, controlling a flowing speed, performing heat-preservation heating, leaving to stand, cooling to the room temperature, collecting modified granules, mixing the modified granules with molten paraffin, performing heating stirring, and performing vacuum freeze-drying, and performing crushing screening so as to obtain modified packing; putting polyether polyol, deionized water, a foam stabilizer, modified packing and diphenylmethane diisocyanate into a flask, performing stirring mixing so as to obtain a mixed liquid, casting into a mold, performing foaming treatment, performing heat-preservation heating, leaving to stand, and cooling to the room temperature, thereby obtaining a hydrophobic porous oil-water separation material.

Description

technical field [0001] The invention relates to a preparation method of a hydrophobic porous oil-water separation material, belonging to the technical field of material processing. Background technique [0002] Marine oil spills have caused catastrophic damage to the marine environment, and the leaked toxic substances have threatened various species through the food chain, including low-level algae to high-level mammals and even humans. From the Toli Kanrong oil spill in 1967 to the Bohai Bay oil spill in 2011, these oil spills have always existed. The hazards of oil spills urgently need to be properly dealt with. Compared with direct burning on the sea surface in the past, it will be a better way to artificially separate the oil in the water, because this kind of treatment can recover the leaked oil again without causing other environmental pollution. Traditional oil-water separation techniques include electrochemical, flotation, centrifugation, filtration and gravity sep...
