Embodiment 1

[0020] Crush the kapok fiber to about 4cm, add it to an aqueous solution containing 1% sodium chlorite, and heat it up to 70°C for 1 hour. After the reaction, the fibers were washed with distilled water until neutral, and the fibers were dried at 70°C to constant weight for later use. 10g kapok fiber after activation is joined in the reactor containing 700ml distilled water, add the 50ml dimethyl formamide solution that is dissolved with 0.045g initiator, 10g butyl methacrylate and 0.045g ethylene glycol dimethacrylate , heated to 80°C and stirred for 2h. After the reaction, the product was repeatedly washed with hot water, dried at 70°C until constant weight, and pulverized. The product in the present embodiment absorbs 48g of diesel oil per gram, 43g of gasoline, and 67g of chloroform.

Embodiment 2

[0022] Crush the kapok fiber to about 3cm, add it to an aqueous solution containing 1.5% sodium chlorite, and heat it up to 70°C for 1 hour. After the reaction, the fibers were washed with distilled water until neutral, and the fibers were dried at 70°C to constant weight for later use. 15g kapok fiber after activation is joined in the reactor containing 700ml distilled water, add the 50ml dimethyl sulfoxide solution that dissolves 0.045g initiator, 12g ethyl methacrylate and 0.06g ethylene glycol dimethacrylate , Warming up to 80°C and stirring for 3h. After the reaction, the product was repeatedly washed with hot water, dried at 70°C until constant weight, and pulverized. The product in the present embodiment absorbs 46g of diesel oil per gram, 41g of gasoline, and 64g of chloroform.

Embodiment 3

[0024] Crush the kapok fiber to about 2cm, add it to an aqueous solution containing 2% sodium chlorite, and heat it up to 70°C for 1 hour. After the reaction, the fibers were washed with distilled water until neutral, and the fibers were dried at 70°C to constant weight for later use. 15g kapok fiber after activation is joined in the reactor containing 700ml distilled water, add the 50ml dimethyl sulfoxide solution that is dissolved with 0.045g initiator, 12g methyl methacrylate and 0.045g ethylene glycol dimethacrylate , heated to 90°C and stirred for 2h. After the reaction, the product was repeatedly washed with hot water, dried at 70°C until constant weight, and pulverized. The product in the present embodiment absorbs 45g of diesel oil per gram, 43g of gasoline, and 63g of chloroform.

Abstract

The invention discloses a kapok fiber-based three-dimensional network oil absorption material. According to the invention, activation-treated kapok fibers are used as base materials, and the three-dimensional network oil absorption material is prepared by grafting copolymerization, crosslinking, washing, drying, and crushing in the presence of an initiator. The dry oil absorption material can absorb diesel oil with a mass being 40-50 times of the mass of the material, can absorb gasoline with a mass being 40-47 times of the mass of the material, and can absorb chloroform with a mass being 60-67 times of the mass of the material. The oil absorption material of the invention is simple in preparation operation, is characterized by high oil absorption rate and high oil absorption speed, and is applicable to fields such as sea, river, lake surface oil pollution, kitchens, and the like.

Description

technical field [0001] The invention relates to the field of oil-absorbing materials, in particular to an oil-absorbing material based on a kapok fiber three-dimensional network. Background technique [0002] In the process of oil extraction, refining, transportation, transfer and use of oil products, crude oil and refined oil spills occur frequently, and the pollution to the water environment is becoming more and more serious. The development of high-efficiency oil-absorbing materials has always been a hot spot of concern. [0003] In recent years, the development of organic-inorganic composite super oil-absorbing resins has received extensive attention. Chinese patents CN101914180A and CN101891860A have prepared super oil-absorbing resins by emulsion polymerization for jet fuel. Chinese patent CN101575404 discloses a method for preparing a super oil-absorbing resin containing cyclodextrin molecules. This technology is a super oil-absorbing resin prepared by a suspension p...
