A kind of oil-absorbing resin and preparation method thereof

Abstract

The invention relates to an oil-absorbing resin and a preparation method thereof. The oil-absorbing resin comprises an oil phase: 5-15 parts of glycol dimethacrylate, 15-30 parts of isobornyl methacrylate, 20-40 parts of p-diphenyl sulfone methacrylate, 10-15 parts of triethylene glycol methacrylate, 10-20 parts of divinylbenzene, 20-30 parts of styrene, 50-200 parts of porogen, 0.5-2 parts of AIBN; and a water phase: 500-1000 parts of distilled water, 5-15 parts of PVA, and 20-50 parts of NaCl. According to the preparation method provided by the invention, the isobornyl methacrylate and the p-diphenyl sulfone methacrylate are used as main synthesis materials, and meanwhile, the non-polar crosslinking agents divinylbenzene and glycol dimethacrylate are used as crosslinking agents, and the styrene with higher hydrophobicity is used as a comonomer to synthetically prepare the oil-absorbing resin which can effectively absorb oil.

Problems solved by technology

It can be seen that domestic research on acrylic oil-absorbing resins is more important, but it is still difficult to obtain products with high oil absorption and easy desorption, regeneration and reuse.
