Abstract

The invention relates to a super-macroporous adsorbent resin and a preparation method thereof, belonging to the field of high polymer materials. The super-macroporous adsorbent resin is prepared from the following raw materials in parts by weight: 50-70 parts of divinylbenzene, 5-10 parts of styrene, 10-20 parts of glycol bis-methacrylate, 5-10 parts of polystyrene, 50-80 parts of diethyl phthalate, 30-50 parts of 200# gasoline, 1-2 parts of diphenyl acyl peroxide, 150-200 parts of deionized water and 1-2 parts of polyvinyl alcohol. The polystyrene and diethyl phthalate used as the pore-forming agent component for preparing the super-macroporous adsorbent resin increase the pore size of the resin and widen the application range of the resin. The second crosslinking agent increases the pore size of the resin, ensures the mechanical strength of the resin and provides the service life of the resin.

Description

technical field [0001] The invention relates to an adsorption resin and a preparation method thereof, more specifically, the invention relates to a super-macroporous adsorption resin and a preparation method thereof, belonging to the technical field of polymer materials. technical background [0002] Macroporous adsorption resin is a kind of polymer adsorption resin with no exchange group and macroporous structure. It has a good macroporous network structure and large specific surface area, and can selectively adsorb organic substances from aqueous solution through physical adsorption. , is a new type of organic polymer adsorbent developed in the 1960s, and has been widely used in environmental protection, food, medicine and other fields. [0003] Macroporous adsorption resin, also known as fully porous adsorption resin, is prepared by polymerizing monomers and additives such as crosslinking agents, porogens, and dispersants through polymerization. After the polymer is form...
