Problems solved by technology

[0006] However, the oil absorption effect of the existing oil-absorbing felt is not high, and the strength of the oil-absorbing felt is low. After the outer layer is partially damaged, it is easy to cause a large area of ​​damage to the oil-absorbing felt as a whole, and the service life is reduced, and the barrier effect of the outer layer material on the oil-absorbing felt body of the inner layer is too strong.

Abstract

The invention proposes a nanofiber oil-absorbing material, which comprises an upper covering layer, an upper absorbing layer, a non-woven fabric layer, a lower absorbing layer and a lower covering layer from top to bottom, and the upper absorbing layer and the lower absorbing layer form a matrix A plurality of accommodation grooves are arranged, and each accommodation groove is filled with nanofibers, and the accommodation grooves of the upper absorbent layer and the lower absorbent layer are arranged in one-to-one correspondence; the four edges of the nanofiber oil-absorbing material are seamed with sutures. The warp and weft interweave between the adjacent two receiving grooves and stitch the edge; the invention has high oil absorption efficiency, improves the service life and increases the tolerance.

Description

technical field [0001] The invention relates to an oil-absorbing material, in particular to a nanofiber oil-absorbing material. Background technique [0002] Usually, during the processing and transportation of oil, a considerable amount of oil will be leaked and discarded, which not only wastes limited resources, but also poses a great threat to the environment. It is very difficult to remove oil pollution. At present, the control of oil pollution in the world is divided into chemical methods and physical methods. [0003] Chemical method: According to the pollution situation, use emulsification dispersion, oil collection or oil coagulation method to control. For oil films with a thickness of less than 1mm, it is effective to use chemical dispersants to clean up oil stains, but chemical cleaning methods need to consume a lot of chemicals and may cause secondary pollution. [0004] Physical method: It is the most commonly used treatment method, including oil containment bo...
