Problems solved by technology

[0004] Although the oil-absorbing resin has a high oil absorption rate and good oil retention, because it floats on the sea surface and is exposed to the sun for a long time, the molecular chain of the high-oil-absorbing resin is easily broken under the light, resulting in the aging of the oil-absorbing resin, which affects the oil-absorbing performance.

Abstract

The invention relates to the field of polymer material synthesis, and discloses a method for preparing oil-absorbing resin balls for absorbing floating oil in the ocean. The steps are: A) preparation of organically modified sepiolite powder; B) preparation of acrylate copolymer emulsion Preparation; C) Preparation of oil-absorbing resin balls. The oil-absorbing resin of the present invention uses the acrylate copolymer as a matrix, and organically modified sepiolite powder is compounded during the synthesis of the acrylate copolymer, which can effectively improve the high oil-absorbing resin and aging resistance.

Description

technical field [0001] The invention relates to the field of polymer material synthesis, in particular to a preparation method of an oil-absorbing resin ball used for absorbing floating oil in the ocean. Background technique [0002] In recent years, the problem of oil spills on the ocean surface has become increasingly prominent, seriously affecting the marine environment, causing serious pollution to sea water quality, and seriously threatening the survival of marine organisms. [0003] For the treatment of marine oil slicks, oil-absorbing materials are generally used to absorb the oil in the water body, and the most commonly used is super oil-absorbing resin. Super oil-absorbing resin is an oil-absorbing material that has developed rapidly in the past ten years. It is a polymer formed by cross-linking lipophilic monomers. The molecules have a three-dimensional cross-linking network structure. Chemicalization causes the resin to swell. Since the super oil-absorbing resin...
