| titleOfInvention | A kind of preparation method of high-strength nanocomposite three-network hydrogel based on waste chrome leather scraps |
| abstract | The invention relates to a preparation method of a high-strength nano-composite three-network hydrogel based on waste chrome leather scraps. In the present invention, montmorillonite is used as nano-filler, poly-2-acrylamide-2-methylpropanesulfonic acid with good salt resistance is used as the first network, polyacrylamide is used as the second network, and waste chrome leather shavings hydrolyzate is used as the first network. Three-network, poly-2-acrylamide-2-methylpropanesulfonic acid-polyacrylamide-waste chrome leather shavings hydrolyzate/montmorillonite nanocomposite three-network hydrogel with high strength and certain temperature and salt resistance was prepared . The use of waste chrome leather scraps for the synthesis of hydrogels can not only utilize the hydroxyl and amino groups in waste chrome leather scraps to form a physical cross-linked network through hydrogen bonding, but also the existing Cr 3+ can coordinate with carboxyl groups. To improve the cross-linking degree of the hydrogel system, and Cr 3+ can exist stably in the hydrogel system without affecting the growth of plants. This kind of material is expected to be used in the field of oil field water blocking, and provides a way for the resource utilization of waste chrome leather scraps. |
