Hydrogel and preparation method thereof

The invention discloses hydrogel and a preparation method thereof. The hydrogel is prepared from the following components: water, fibroin, sodium alginate, glucuronic acid, succinic acid diester, thermophilic cellulose decomposition bacteria, protease producing bacteria, polyvinyl alcohol, polyacrylamide, a cross-linking agent, a hardening agent, a pH regulator, a stabilizer and a thickening agent. The hydrogel and the preparation method thereof have the advantages that the biodegradability is higher, the decomposition speed in the natural environment is higher, and the long-term influence on the soil and the environment can be avoided. 本发明公开了一种水凝胶及其制备方法，包括以下成分：水、蚕丝蛋白、海藻酸钠、葡萄糖醛酸、琥珀酸二酯、嗜热纤维素分解菌、蛋白酶产生菌、聚乙烯醇、聚丙烯酰胺、交联剂、硬化剂、pH调节剂、稳定剂、增稠剂；该水凝胶及其制备方法生物降解性较强，在自然环境中分解速度较快，能够避免对土壤和环境造成长期影响。
