Embodiment 1

[0022] (1) Weigh 0.02g of sodium dodecylbenzene sulfonate and 0.03g of gelatin, dissolve them in 150ml of deionized water, stir until a transparent solution, and add them into a three-necked flask.

[0023] (2) Weigh 20g of styrene, 10g of butyl methacrylate, 0.6g of benzoyl peroxide, 0.4g of divinylbenzene, and 12g of ethyl acetate, mix them and put them into a three-necked flask.

[0024] (3) Slowly heat up to the polymerization reaction temperature, and react for 8 hours.

[0025] (4) After the reaction, the product was filtered out and washed three times with absolute ethanol and warm water successively.

[0026] (5) The product is dried in a vacuum drying oven to constant weight to obtain a porous super oil-absorbing resin.

[0027] In this embodiment, the amount of porogen used is 40% of the total mass of the monomers. The oil absorption performance test of the obtained resin shows that the oil absorption rate of the sample to carbon tetrachloride is 22.74g / g, and the o...

Abstract

The invention discloses a binary fast porous high-oil-absorption resin and a preparation method thereof. The binary fast porous high-oil-absorption resin is synthesized according a suspension polymerization method by taking styrene and methacrylate as monomers in the presence of a pore-forming agent. The binary fast porous high-oil-absorption resin prepared through the method disclosed by the invention has an irregular porous structure on the surface, thereby enlarging the specific area of resin and effectively enhancing the oil absorption velocity and oil absorption magnification of the resin for an oil product. The binary fast porous high-oil-absorption resin prepared through the method disclosed by the invention has good development prospect in the fields of treatment of ocean floating oil and industrial oily wastewater.

Description

technical field [0001] The invention relates to an oil-absorbing material and a preparation method thereof, more specifically, to a binary rapid porous high oil-absorbing resin and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of world industry and the continuous improvement of people's living standards, the transportation and use of oil and various oil products have become a part of modern life. However, oil tanker leakage accidents, industrial oily wastewater discharge and other problems are also becoming more and more serious. Therefore, the development and research of high-quality oil-absorbing materials has become one of the major research topics. [0003] At first, people used porous substances such as cotton, sponge, and clay to absorb oil. These traditional oil-absorbing materials have the advantages of convenient use, low price, and biodegradability. However, their disadvantages such as low oil absorption, ...
