以纤维素(棉浆粕)为基材、硝酸铈铵-HNO_3为引发剂、甲基丙烯酸丁酯(BMA)为接枝单体、N,N′-亚甲基双丙烯酰胺为交联剂,采用悬浮振荡接枝聚合法合成了棉浆粕-BMA接枝聚合吸油材料。用FFIR,XRD,SEM,TG-DSC等分析手段对产物的结构进行了表征,提出了用聚合度增量法测定产物接枝率的新方法,并对产物的吸油率、保油率、吸油速率、水面浮油回收率等吸油性能及其重复使用性能进行了分析。实验结果表明,产物为棉浆粕与BMA的接枝聚合物,该产物对黏度较大和极性较强的油品有较高的吸油率,对各类油品都具有较高的吸油速率,对不易挥发的油品有较好的保油率,水面浮油回收率低于产物饱和吸油率,回收规律与吸油规律基本一致,即吸油性能较好的试样对水面浮油的回收能力也较高。
Using cellulose (cotton pulp) as substrate, cerium ammonium nitrate-HNO3 as initiator, butyl methacrylate (BMA) as grafting monomer and N, N’-methylenebisacrylamide as crosslinking agent , Cotton pulp-BMA grafted polymerization oil-absorbing material was synthesized by suspension-vibration graft polymerization. The structure of the product was characterized by means of FFIR, XRD, SEM and TG-DSC. A new method for determining the grafting yield of product was proposed by using the polymerization degree increment method. The oil absorption rate, oil retention rate, oil absorption Rate, surface oil recovery and other oil absorption properties and their repeated use performance were analyzed. The experimental results show that the product is a graft polymer of cotton pulp with BMA. The product has higher oil absorption rate to the oil products with larger viscosity and higher polarity, and has higher oil absorption rate for all kinds of oil products. The less volatile oil has a good oil retention rate, the water surface oil recovery rate is lower than the product saturated oil absorption rate, the recovery law and the oil absorption law is basically the same, that is, good oil absorption performance of the sample of the oil slick surface recovery ability Higher.
