Strong-alkalinity composite ion exchange resin material and preparation method thereof

Abstract

The invention relates to a strong-alkalinity composite ion exchange resin material and a preparation method thereof and is mainly used for solving the problems of low heat resistance and swelling resistance of the strong-alkalinity ion exchange resin in the prior art. The strong-alkalinity composite ion exchange resin material comprises the following components in percentage by weight: a) 75-90% of polymer monomer; b) 5-15% of copolymer monomer; c) 0.1-5% of graphene; and d) 0.1-10% of initiator. The technical can be used for solving the problem relatively well and can be applied to the industrial production of strong-alkalinity composite ion exchange resin material.

Description

technical field

[0001] The invention relates to a strongly basic composite ion exchange resin material and a preparation method thereof. Background technique

[0002] Strongly basic anion exchange resins can be used in water treatment, substance purification, concentration, separation, transformation of ionic composition of substances, decolorization of substances, and catalysts.

[0003] There have been some publications on the technology of developing strongly basic anion exchange resins at home and abroad. Document SU675056 discloses introducing 2% 2-mercaptobenzimidazole in chloromethyl polystyrene resin, and then reacting with trimethylamine to prepare strong base anion exchange resin. Document JP01-75041 discloses a triethyldiamine type strong base anion exchanger having a tricyclic structure. Document JP07-24334 discloses a high-temperature-resistant anion exchanger used as a gas adsorbent, which is characterized in that there is no hydrogen on the methylene α-C be...
