Problems solved by technology

[0002] In recent years, with the rapid development of the chemical industry, more and more oily sewage and offshore oil spills have caused great harm to the environment. Traditional oil-absorbing materials have low oil absorption ratio, poor oil-water selectivity, and poor oil retention rate. Disadvantages such as post-processing troubles cannot meet the needs, so the research and development of green and efficient oil stain removers has become a hot research topic in environmental science

Embodiment 1

[0028] Accurately weigh 6g of OP-10 liquid, add 94g of water, and prepare an OP-10 solution with a mass fraction of 6%.

[0029] Add 0.0042g of N,N-methylenebisacrylamide, 0.0050g of sodium dodecylbenzenesulfonate and 2ml of OP-10 solution with a mass fraction of 6% and 1ml of water in a 50ml round bottom flask, and disperse by ultrasonic for 25min Then, 0.0054 g of azobisisobutyronitrile and 8 ml of lauryl methacrylate were added. The mixture was magnetically stirred and protected by nitrogen, and reacted at 70°C for 6 hours to obtain a spongy polymer product, which was washed with absolute ethanol and dried at 50°C to obtain a super oil-absorbing resin.

Abstract

The invention relates to a porous high-oil-absorption resin and a preparation method thereof. The high-oil-absorption resin is prepared by radical-triggered composite emulsion polymerization of a monomer in the presence of a cross-linking agent, a trigger and an emulsifier and in a protective atmosphere of nitrogen. The high-oil-absorption resin in a small volume has high oil absorption rate and can absorb only oil but not water; after absorbing oil, the resin becomes a block and is easy to recover; with a density smaller than that of water, the resin can float on water and thus can well treat floating oil; and the resin has a certain application value in fields of petroleum, chemicals, environment protection and medicines.

Description

technical field [0001] The invention aims to provide a method for preparing porous high-absorbing grease. Background technique [0002] In recent years, with the rapid development of the chemical industry, more and more oily sewage and offshore oil spills have caused great harm to the environment. Traditional oil-absorbing materials have low oil absorption ratio, poor oil-water selectivity, and poor oil retention rate. Disadvantages such as post-processing troubles cannot meet the needs, so the research and development of green and efficient oil stain removers has become a hot research topic in environmental science. [0003] Super oil-absorbing resins can be roughly divided into two categories according to different polymerized monomers: one is acrylic; the other is olefin. Due to the wide range of sources of acrylate monomers, there are many studies. Lin Hailan (Lin Hailan, Liao Jianhe, etc., the synthesis and performance research of acrylate copolymer super oil-absorbin...
