Synthetic method for modified carbon nanotube and acrylate composite high-oil-absorption resin

[0032] (1) Refining of benzoyl peroxide (BPO):

[0033] Add 4 grams of benzoyl peroxide to 20 ml of chloroform, and stir and dissolve a certain amount of benzoyl peroxide in chloroform. The solution was suction filtered to obtain the filtrate, and the above filtrate was slowly added dropwise to 40ml of absolute ethanol (ice-water bath), and left to stand until no white needle-like crystals precipitated. Filter and wash the precipitate, then put it in a vacuum drying oven to dry, and put the product in a brown bottle and keep it sealed for later use.

[0034] (2) Modification of carbon nanotubes:

[0035]Weigh a certain amount of MWNTs into a beaker, add 2.7molL-1 nitric acid solution, ultrasonically disperse for 20min, transfer to a round bottom flask, heat the oil bath to about 110°C, and mechanically stir and reflux for 10h. Transfer the carbon nanotube-nitric acid mixture to a beaker, let it stand, and remove the supernatant. Add deionized water to wash, and repeat the a...

[0041] (1) Refining of benzoyl peroxide (BPO):

[0042] Add 5 grams of benzoyl peroxide to 30 ml of chloroform, and stir and dissolve a certain amount of benzoyl peroxide in chloroform. Suction filter the solution to obtain the filtrate, slowly add the above filtrate dropwise into 60ml of absolute ethanol (ice-water bath), and let stand until no white needle-like crystals precipitate. Filter and wash the precipitate, then put it in a vacuum drying oven to dry, and put the product in a brown bottle and keep it sealed for later use.

[0043] (2) Modification of carbon nanotubes:

[0044] Weigh a certain amount of MWNTs into a beaker, add 2.7molL-1 nitric acid solution, ultrasonically disperse for 20min, transfer to a round bottom flask, heat the oil bath to about 110°C, and mechanically stir and reflux for 10h. Transfer the carbon nanotube-nitric acid mixture to a beaker, let it stand, and remove the supernatant. Add deionized water to wash, and repeat the above cleaning proc...

[0050] (1) Refining of benzoyl peroxide (BPO):

[0051] Add 7 grams of benzoyl peroxide to 35 ml of chloroform, and stir and dissolve a certain amount of benzoyl peroxide in chloroform. The solution was filtered with suction to obtain the filtrate, which was slowly added dropwise to 70ml of absolute ethanol (ice-water bath), and left to stand until no white needle-like crystals precipitated. Filter and wash the precipitate, then put it in a vacuum drying oven to dry, and put the product in a brown bottle and keep it sealed for later use.
