[0024] Add 42.0 grams of p-chloromethylstyrene, 2.6 grams of divinylbenzene and 0.3 grams of benzoyl peroxide initiator in a 250 milliliter three-necked flask, and stir at 60° C. for 1.5 hours; then add 1.4 grams of multi-walled carbon nanotubes , continue to stir for 1 hour for pre-polymerization. 130 mL of deionized water in which 1.3 g of polyvinyl alcohol had been dissolved was added. Adjust the stirring speed, while gradually raising the temperature to 80°C, and react for 5 hours; then raise the temperature to 90°C, react for 5 hours, and finally raise the temperature to 98°C, and react 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 0.35-0.60 mm.

[0025] In a 250 ml three-necked flask, add 30.0 g of composite microspheres A and 60 ml of dichloroethane, adjust the temperature of the water bath to ...

Embodiment 2

[0029]In a 500 ml three-neck flask, add 4.6 g of polyvinyl alcohol and 300 ml of deionized water, start stirring and raise the temperature to completely dissolve the polyvinyl alcohol. Stop stirring, add 63.0 grams of p-chloromethylstyrene, 6.0 grams of divinylbenzene and 0.5 grams of benzoyl peroxide initiator, and a mixed solution of 4.9 grams of multi-walled carbon nanotubes after cooling slightly. Adjust the stirring speed while gradually raising the temperature, and react at 80°C for 5 hours; then raise the temperature to 88°C, continue the reaction for 5 hours, and finally raise the temperature and react at 100°C for 6 hours. After the reaction, pour out the upper liquid, wash with hot water, filter, put in an oven to dry at 80°C, and sieve to collect composite microspheres B with a particle size in the range of 0.35-0.60 mm.

Abstract

The invention relates to strongly basic carbon nanotube composite resin and its preparation method, and mainly aims to solve the problems of poor heat resistance and swelling resistance of ion exchange resin involved in previous technologies. The composite resin of the invention comprises: (1) 75-90% of a monomer; (2) 5-15% of a comonomer; (3) 0.1-5% of a nano-material; (4) 0.1-10% of an initiator. Specifically, the monomer is at least one of p-chloromethyl styrene, 4-(3-chloropropyl) styrene, 4-(3-bromopropyl) styrene, 4-(4-chlorobutyl) styrene, 4-(4-brombutyl) styrene, 4-(5-chloropentyl) styrene or 4-(5-bromopentyl) styrene; the comonomer is at least one of glycol dimethacrylate, 2-propenylbenzene, divinyl phenylmethane, and divinylbenzene;the nano-material is at least one of a multi-walled carbon nanotube, a single-walled carbon nanotube, C60 or C70 etc. fullerene; and the initiator is at least one of benzoyl peroxide, azodiisobutyronitrile, lauroyl peroxide, and cumene hydroperoxide. The composite resin and its preparation method of the invention well solves the above problems, and can be used in the industrial production of oxirane catalytic hydration.

Description

technical field [0001] The invention relates to a strongly basic carbon nanotube composite resin and a preparation method thereof. Background technique [0002] Carbon nanotubes are a new type of material. Since carbon nanotubes were discovered, their unique structure and properties have caused a wave of research in the scientific community (Iijima, S.; Ichihashi, T.Nature 1993, 363, 603- 605; Wang, C.C.; Guo, Z.X.; Fu, S.K.; Wu, W.; Zhu, D.B. Progress in Polymer Science 2004, 29, 1079-1141.). Due to the similar structure of carbon nanotubes and polymers, and excellent mechanical and electrical properties, compounding carbon nanotubes and polymers can obtain high specific strength, strong designability, good fatigue resistance, and excellent molding process. Polymer nanocomposites with advantages such as simplicity can realize the complementary advantages of the two, so as to effectively use the excellent mechanical properties, thermal stability and electrical conductivity ...
