Abstract

The invention discloses a kapok sandwich construction non-woven oil absorbing material. The material is composed of a kapok sandwich layer and an anti-seepage layer located at one side of the kapok sandwich layer, wherein the kapok sandwich layer is composed of an oil storage layer and oil absorbing layers located on both sides of the oil storage layer, the oil absorbing layer is micro-denier polypropylene needle-punched nonwoven cloth, the oil storage layer is a kapok fiber web, and the anti-seepage layer is polypropylene spun-bond nonwoven cloth. The kapok sandwich construction non-woven oilabsorbing material has the advantages that the oil absorption ratio is higher, the oil-holding property is good, and the material has reusability and certain degradability.

Description

technical field [0001] The invention belongs to the field of adsorption material structure and relates to a non-woven oil absorption material with kapok sandwich structure. Background technique [0002] In recent years, offshore oil spills have occurred frequently, and the harm of oil pollution cannot be underestimated. At present, how to effectively deal with oil spill pollution has become a global problem. Methods to deal with oil pollution are divided into chemical and physical methods. Among them, the chemical method is processed by using dispersants and direct combustion. Although this method is simple and fast in processing speed, it will produce a large amount of chemical residues. In contrast, physical recovery uses oil-absorbing materials or separators to absorb and store marine oil spills, which can not only effectively clean up pollution, but also easily recover substances after oil absorption, which is an ideal oil spill treatment method.
