Problems solved by technology

However, the oil absorption ratio of these high oil-absorbing resins reported so far is not high, this is because the high oil-absorbing resin is a high molecular polymer with a low degree of crosslinking inside.

Embodiment 1

[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...

Embodiment 2

[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...

Embodiment 3

[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.

[0052] (2) Modification of carbon nanotubes:

[0053] 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.

Abstract

The invention belongs to the field of synthesis of polymeric nanocomposites, and relates to modification of carbon nanotubes, in particular to a preparation method for acrylate / carbon nanotube composite resin with high oil absorption performance. The acrylate / carbon nanotube composite resin is synthesized by polymeric monomer butyl acrylate and butyl methacrylate, modified carbon nanotubes MWNTs-KH570, N-N methylene bisacrylamide, purified benzoyl peroxide and ethyl acetate at constant pressure and under the protection of nitrogen. The acrylate / carbon nanotube composite resin has the advantages that the oil and water selectivity is favorable, various oil products can be absorbed, the oil absorption rate can reach tens to dozens of times, the mass is low, the size is small, and the transportation and the storage are easy.

Description

Technical field: [0001] The invention belongs to the field of polymer nanocomposite material synthesis, relates to the modification of carbon nanotubes, in particular to a method for preparing an acrylate / carbon nanotube composite resin with high oil absorption performance. Background technique: [0002] In recent years, with the rapid development of my country's industrial production, the demand for crude oil and oil products has increased, and they have been widely used and transported. The number of oil spill incidents of various sizes has continued to increase, and the occurrence of oil spill accidents is on the rise. The anhydrous discharge of insoluble organic matter and the occurrence of accidents in chemical raw material warehouses, large chemical plants and other centralized storage places for chemical raw materials have brought great threats to the water environment, soil and the surrounding environment where the accident occurred. On April 20, 2010, a drilling pl...
