Abstract

The invention provides a preparation method of super absorbent resin for removing water of oil products. The method comprises the following steps: adding a cross-linking agent into a water-soluble acrylic monomer water solution with a certain neutralization degree, and fully mixing; adding a first polymerization inhibitor and an initiator into the obtained mixed solution, and fully mixing; dropwise adding the obtained solution into an organic solvent, wherein a surface active agent, an oil-soluble acrylic monomer and a second polymerization inhibitor are dissolved in the organic solvent at the certain temperature, separating water and removing water while stirring, cooling to the room temperature after the reaction is finished, wherein the obtained solid product is the product. The preparation method provided by the invention can solve the compatibility problem of the super absorbent resin in the oil products and the swelling and cracking problems, caused by excessive water absorption, of the super absorbent resin.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a preparation method of a superabsorbent resin used for dewatering oil products. Background technique [0002] Superabsorbent resin is a new type of polymer functional material developed since the 1970s. It is a macromolecule containing hydrophilic groups and a cross-linked structure, capable of absorbing hundreds of times its own weight in water. After absorbing water, it swells into a hydrogel, and even if a certain pressure is applied at room temperature, the adsorbed water will not precipitate, and it can be reused after drying. This excellent water absorption and water retention performance makes it widely used in the fields of industry, agriculture, food processing, medical hygiene and environmental protection. [0003] Oil products contain water brought in or artificially added during production. Excessive water content can easily lead to oil deterioration, con...
