Oil-absorbing resin and preparation method

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.

Description

Technical field [0001] The present invention involves an oil -absorbing resin and its preparation methods. More specifically, the present invention involves a kind of solid surface, industrial emissions of wastewater or other channels into various water bodiesOil -absorbing resin materials and preparation methods for sexual substances are adsorbed and recycling. Background technique [0002] With the rapid development of my country's industrialized production, including the emissions of oil -containing or other insoluble organic sewage, leakage of oil tankers and tanker trucks, large chemical factories, chemical raw materials warehouses and other chemical raw material storage accidents, soil, river, ocean, ocean, and ocean The surrounding environment around the accident caused serious pollution and became an increasingly serious problem. [0003] Traditional oil -absorbing materials, such as activated carbon, clay, natural fiber fabrics, polypropylene fiber, etc., whether in term...

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.
