Embodiment 1

[0044]Get 34 grams of p-iodomethylstyrene, 1.5 grams of divinylbenzene, 0.5 grams of benzoyl peroxide initiator and 2.5 grams of single-layer graphene, stir for 1 hour and mix evenly, take out 5 grams of mixed solution, add 0.8 gram of iodoform, shake and mix in a low-temperature water bath to obtain solution A, and the remaining mixed solution is set aside. Take a 500 ml three-neck flask and add 200 ml of deionized aqueous solution in which 2 g of polyvinyl alcohol has been dissolved. The previously prepared solution A was added dropwise, and the air was replaced by argon after being sealed, heated to 80°C, and reacted for 5 hours; then heated to 90°C, reacted for 5 hours, and finally heated to 98°C, reacted for 6 hours. After the reaction, pour out the upper liquid, wash it with hot water, then filter it, put it in an oven to dry at 80°C, and sieve it to collect the composite microspheres A with a particle size in the range of 0.35-0.60mm.

Abstract

The invention relates to a strongly basic composite ion exchange resin material and a preparation method thereof, and mainly solves the problems in the prior art that the content of the basic active group in the catalyst of the strong basic ion exchange resin is low and correspondingly the activity of the catalyst is not high during the application process . The present invention comprises the following components based on the weight percentage of the total weight of the resin material: (a) 72 to 87 parts of polymerized monomers; (b) 4 to 18 parts of comonomers; (c) 0.1 to 10 parts (d) 0.1 to 1 part of chain transfer agent component; (e) the technical scheme of 0.1 to 10 parts of initiator solves this problem well, and can be used for strong basic composite ion exchange resin material catalyst in industrial production.

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 into chloromethyl polystyrene resin, and then reacting with trimethylamine to prepare strong base anion exchange resin. The document JP01-75041 discloses a triethyldiamine type strong base anion exchanger having a tricyclic structure. The 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 methyle...
