摘要
以水稻秸秆和丙烯酸(AA)、丙烯酰胺(AM)等为主要原料,然后将适量的聚乙烯醇(PVA)加入,以低毒甘油(GL)作交联剂,腐殖酸作为营养剂制备保水剂。首先将水稻秸秆原料进行预处理,提取纤维素,然后将其与乙丙烯酸和丙烯酰胺按照一定的配比混合,加入过硫酸钾和腐殖酸在加热条件下进行接枝共聚反应,反应产物干燥粉碎后即得到营养保水剂产物产品。
This work reported the preparation and adsorption properties of a kind of agricultural wstraw. The rice straw was first extracted and mixed with acrylic acid （AA）,acrylamide （AM） . Then, pglycerol （GL） were added as cross linking agent,and humic acid （HA） was added as a nutritional agent to prepare the water retaining agent In the work,the effect of different raw materials and other conditions on the water adsorption ability of the water retaining age^ were investigated. The final agricultural nutritional water retaining products were obtained ater drying the reaction pol}mier in drying cabinet.
