Problems solved by technology

[0006] The technical problem mainly solved by the present invention is that traditional oil-absorbing materials, such as sponge, clay and other porous substances are widely used. Although these materials have good oil-absorbing effect, the structural properties of the material itself make the traditional oil-absorbing materials have low oil-absorbing capacity. Large, low oil-water selectivity, the oil-absorbing material is not easy to degrade after absorbing oil, the comprehensive cost of waste treatment is high, the reusability is poor, and it is easy to cause secondary pollution to the environment. A degradable oil-absorbing material is provided. preparation method

Abstract

The invention relates to the technical field of preparation of oil absorbing materials, and specifically relates to a preparation method of a degradable oil absorbing material. According to the preparation method, meerschaum and enteromorpha prolifera are used as raw materials to prepare activated stone slurry and purified algae cellulose, nanofiber is scattered in the activated stone slurry so asto obtain nanofiber sponge sizing agent, the purified algae cellulose and the nanofiber sponge sizing agent are mixed so as to obtain a dispersed sizing agent, and compound sponge fiber, poly dimethylsiloxane, liquid paraffin wax and other matters are mixed and put into a fermentation tank to be fermented and modified, so as to obtain the degradable oil absorbing material. The meerschaum fiber isadsorbed on the surface and in pores of the organic nanofiber, so that the oil absorbing quantity of the oil absorbing material is increased; the poly dimethylsiloxane and other oily matters generateoleophilic nonpolar radicals on the surface of the fiber sponge, so that the oleophilic and hydrophobic performance of the fiber sponge is enhanced; and the fiber materials and the stone slurry are easy to recycle and do not pollute the environment. The preparation method has a bright application prospect.

Description

technical field [0001] The invention relates to the technical field of preparation of oil-absorbing materials, in particular to a method for preparing degradable oil-absorbing materials. Background technique [0002] In recent years, the frequent occurrence of offshore oil spill accidents and the massive discharge of industrial oily sewage have made the problem of oil-water separation become the focus of attention again. Oily sewage has a wide range of sources, such as oil spills, land mining of petroleum ore, food, textiles, machinery processing and many other industries discharge a large amount of oily sewage into the environment. Whether it is industrial oily sewage or domestic oily sewage, any discharge is harmful to production. The living environment has caused great pollution, and the resulting environmental problems cannot be ignored. [0003] In recent decades, the research and application of oil-absorbing materials has developed rapidly and has a wide range of uses...
