Hydrophilic oil absorption cotton

Abstract

The invention relates to hydrophilic oil absorption cotton. The oil absorption cotton consists of a hydrophilic and oleophylic adjuvant layer and a filtering layer covering the adjuvant layer, wherein the hydrophilic and oleophylic adjuvant layer is prepared from a super-amphiphilic material; the filtering layer is prepared from composite filtering cotton; the composite filtering cotton comprises a filtering cotton layer; active carbon particles are uniformly distributed in the filtering cotton layer; nonwoven cloth thin layers which are difficult to defiber are arranged on the top surface and the bottom surface of the filtering cotton; the super-amphiphilic material is a macromolecular carbon nano composite material; the composite material contains a nano-level space consisting of a hydrophilic polymer chain section and an oleophylic polymer chain section which are regularly arrayed. The hydrophilic oil absorption cotton has dual effects of oil absorption and water absorption; the filtering layer and the hydrophilic and oleophylic adjuvant layer are of multihole structures; on the premise of guaranteeing high oil absorption rate, the oil absorption rate is also increased.

Description

technical field [0001] The invention relates to the field of materials, in particular to a hydrophilic oil-absorbing cotton. Background technique [0002] In recent years, with the development of offshore oil development and transportation, oil spills on the sea surface have occurred from time to time. This has not only caused a waste of oil resources, but also caused ecological environmental problems and water pollution. At the same time, the discharge of some wastewater containing organic matter also poses a certain threat to the ecological environment. Oil spills have caused many adverse effects on ecosystems, leading to a growing problem of environmental pollution. In order to protect the ecological environment, a large number of oil-absorbing materials have emerged, and have been widely developed and used. [0003] Ordinary oil-absorbing material itself only absorbs oil but not water. It can only be placed on the water surface to absorb oil stains, and cannot be used...

AI Technical Summary

Problems solved by technology

[0003] Ordinary oil-absorbing material itself only absorbs oil but not water. It can only be placed on the water surface to absorb oil stains, and cannot be used to filter oil stains and other impurities in water at the same time. However, many sewages contain various impurities such as algae, and a single oil-absorbing material cannot satisfy users. The purpose of filtering oil and impurities at the same time, therefore, the use of ordinary oil-absorbing materials is limited
