Abstract

The invention discloses a preparation method of a high efficient oil storage type oil absorbent felt material, and belongs to the field of oil pollution treatment. Oyster mushroom bran is processed byplasma to increase the content of polar groups on the surface so as to improve the lipophilic property and oil adsorption performance; methyl methacrylate and butyl acrylate are used to prepare composite resin, which can increase the oil absorption amount and has good mechanical stability and lipophilic-hydrophobic properties; processed chitosan is added to enhance the oil absorbing performance of the oil absorbent felt material, moreover, chitosan has excellent thermal stability and a good solid-solid phase change performance; when the oil absorbent felt material is used in an environment with a large temperature difference, during the solid-solid phase change process, the chitosan can maintain a relatively stable volume in the oil absorbent felt material, and thus other components can well exert their functions. The problem that the oil absorbing performance and oil storage performance of a conventional oil absorbent felt are not good is solved.

Description

technical field [0001] The invention relates to the field of oil pollution treatment, in particular to a preparation method of an efficient oil storage type oil-absorbing felt material. Background technique [0002] Oil-absorbing felt is made of polypropylene, an inert chemical substance, through a melt-blown process, which can effectively absorb liquid and retain it. Adsorption products are all wrapped in polypropylene fibers or non-woven fabrics that are sewn with threads and treated with surface-activating agents. The outer fabric is extremely tough and durable, with strong capillary absorption and strong adsorption , so as to absorb the leaked liquid and flow to the oil-absorbing cotton, which effectively prevents the spread of the leak. The product can be reused after being twisted and squeezed, and 72% -90% of the leaked liquid can be recovered (depending on the manufacturing process and quality of the oil-absorbing cotton). The advantages of this material are flame r...
