Embodiment 1

[0033] a) Pollen pretreatment step: Soak 5 g of rapeseed pollen grains in 75 mL ethanol solution for 5 h, then ultrasonically clean for 2 h, filter with suction, wash with water and ethanol for 3 times, collect 5 g of pollen and disperse them in a solution containing 12.5 mL formaldehyde and 37.5 mL ethanol mixture for 10 min, suction filtered, washed with water and ethanol three times, then soaked in 60 mL of 12 mol / L sulfuric acid for dehydration under magnetic stirring for 4 h, suction filtered, and removed Wash with deionized water until the filtrate is neutral, and dry at 80°C.

[0034] b) Modification step of pollen particles: the pollen obtained in step a) was heated to 500°C in nitrogen and calcined for 2 h to obtain a carbonized pollen skeleton. at 100°C with HNO 3 The pollen surface was activated by steam for 5 h, cooled, filtered with suction, washed with water and ethanol until the filtrate was neutral, and dried at 80°C for 12 h. The resulting 0.3 g of nitric acid...

Abstract

The invention belongs to the technical field of preparation of modified functional polymer materials, and relates to preparation of an oil-absorbing material, specifically to preparation and application of a modified pollen biomass carbon composite acrylate oil-absorbing material. The preparation method disclosed by the invention comprises the following steps: subjecting pollen to pretreatment, carrying out steam activation with HNO3, then carrying out hydrophobic modification, with a deionized water solution containing a dispersant namely polyvinyl alcohol as a reaction system, carrying out heating to 60 to 90 DEG C, carrying out stirring for 30 min, carrying out cooling, and adding butyl acrylate, butyl methacrylate, hydrophobic pollen biomass carbon, an initiator, a crosslinking agent namely N-N-methylene bisacrylamide and a pore-forming agent namely an ethyl acetate mixed solution; and carrying out programmed heating synthesis by utilizing microwave radiation. The composite material prepared by utilizing the method provided by the invention has the advantages of good structure and thermal stability, an internal well-developed three-dimensional network structure, excellent hydrophobic lipophilicity, significantly-improved oil-absorbing effect, and capability of being applied to selective adsorption and recovery of various oil products and environment control problems like sewage treatment.

Description

technical field [0001] The invention belongs to the technical field of preparation of modified functional polymer materials, and relates to the preparation of oil-absorbing materials, in particular to the preparation and application of modified pollen biomass carbon composite acrylate oil-absorbing materials. Background technique [0002] Ecological harmony is an important indicator of social development. At present, frequent oil spill accidents and a large amount of oily wastewater discharged from industry and households have brought serious negative impacts on the environment and ecosystem. Efficient absorption and selective separation of oil are urgent needs for environmental governance. Solved technical problems. For a long time, people have used traditional oil-absorbing or oil-water separation materials such as oil booms, oil skimmers, kapok fibers or polypropylene non-woven fabrics, but existing problems such as low hydrophobicity, low adsorption capacity, low oil-wat...
