Embodiment 1

[0012] 1 g of human hair keratin, dispersed in 10 ml of dimethyl sulfoxide, sequentially added 0.4 g of 4-methylaminopyridine, 0.5 ml of triethylamine and stirred to dissolve, then slowly added dropwise 0.4 ml of 2-bromoiso Butyryl bromide, reacted at room temperature for 24 hours. After washing and drying to obtain a keratin macromolecular initiator, take 0.2 g of the macromolecular initiator, dissolve it in 7.5 milliliters of N,N-dimethylformamide, add 7.5 milliliters of butyl methacrylate, 0.06 milliliters of pentaerythritol tris Acrylic ester, 0.015 g of copper powder, 0.07 ml of tetramethylethylenediamine, and conduct single electron transfer living radical polymerization at 65 degrees Celsius for 24 hours.

[0013] The oil absorption ratio of the obtained high oil-absorbing gel to chloroform is 37 times.

Embodiment 2

[0015] 1 g of human hair keratin, dispersed in 20 ml of dimethyl sulfoxide, sequentially added 0.8 g of 4-methylaminopyridine, 1.0 ml of triethylamine and stirred to dissolve, then slowly added dropwise 0.8 ml of 2-bromoiso Butyryl bromide, reacted at room temperature for 24 hours. After washing and drying to obtain a keratin macromolecular initiator, take 0.1 g of the macromolecular initiator, dissolve it in 7.5 milliliters of N, N-dimethylformamide, add 7.5 milliliters of butyl methacrylate, 0.06 milliliters of pentaerythritol tris Acrylate, 0.015 g of copper powder, 0.07 ml of tetramethylethylenediamine, single electron transfer living radical polymerization at 75 degrees Celsius, and react for 24 hours.

[0016] The oil absorption ratio of the obtained high oil-absorbing gel to chloroform is 44 times.

Embodiment 3

[0018] 1 g of human hair keratin, dispersed in 20 ml of dimethyl sulfoxide, sequentially added 0.8 g of 4-methylaminopyridine, 1.0 ml of triethylamine and stirred to dissolve, then slowly added dropwise 0.8 ml of 2-bromoiso Butyryl bromide, reacted at room temperature for 24 hours. After washing and drying to obtain a keratin macromolecular initiator, take 0.1 g of the macromolecular initiator, dissolve it in 7.5 milliliters of N, N-dimethylformamide, add 7.5 milliliters of butyl methacrylate, 0.06 milliliters of trihydroxy Methyl propane triacrylate, 0.015 g of copper powder, and 0.07 ml of tetramethylethylenediamine were subjected to single electron transfer living radical polymerization at 65 degrees Celsius for 24 hours.

[0019] The oil absorption ratio of the obtained high oil-absorbing gel to chloroform is 35 times.

Abstract

The invention discloses a method for modified preparation of high-oil-absorption gel through human hair keratin. The method is characterized by comprising the steps of firstly, using a reducing solution to extract the keratin from human hair, then using 2-bromoisobutyryl bromide to modify and obtain keratin macroinitiator, dissolving the keratin macroinitiator in N,N-dimethyl-formamide, adding monomers, a cross-linking agent, a catalyst and ligands sequentially, performing single electron transfer living radical polymerization, and obtaining the high-oil-absorption gel. By the aid of the preparation method, the high-oil-absorption gel with the oil absorption rate of 44 times on chloroform can be obtained.

Description

technical field [0001] The invention relates to a method for preparing high oil-absorbing gel by modifying human hair keratin, belonging to the field of functional polymer materials. Background technique [0002] High oil-absorbing resin is a new type of functional polymer material developed in the 1960s. It has the characteristics of large oil absorption, fast oil absorption rate, and good oil retention performance. It has received extensive attention in recent years. However, the main problem of this kind of super oil-absorbing resin is that it is difficult to biodegrade, and the synthesis of biodegradable bio-based super oil-absorbing resin is an important research topic at present. Human hair is a widespread waste protein resource, the main component of which is keratin. Hybridization of protein peptide chains into traditional carbon chain polymers can not only solve the environmental pollution problems caused by traditional polymers, but also fully Utilize waste protei...
