摘要
淀粉是重要的天然胶粘剂的原料,因其价格低廉,原材料丰富,被广泛应用于各个领域。但是天然淀粉的耐热、耐酸、耐剪切等性能较差,对其使用造成很大的局限性,因此必须进行适当的改性。通过不同的改性方法可以改变淀粉的黏度、溶胀性、黏附性等各种理化性质,从而使制得的胶粘剂符合人们的需求。常用的改性方法有化学改性(酸、氧化、酯化、接枝、交联)、物理改性和复合改性等。主要阐述了这三种改性方法的原理以及对淀粉结构和性能的影响,最后对淀粉基胶粘剂未来的发展进行了展望。
Starch is an important material for natural adhesives,and it is widely used in various fields because of its low price and wide range of raw materials.However,natural starch has great limitations in its use due to its poor resistance to heat,acid and shear,so it must be suitably modi-fied.Different modification methods can change the viscosity,swelling,adhesion and other physical and chemical properties of starch,so that the re-sulting adhesive can meet the needs of people.Commonly used modification methods include chemical modification(acid,oxidation,esterification,grafting,cross-linking),physical modification,compound modification,etc.The principles of these three modification methods and their effects on the structure and properties of starch are described,and the future development of starch-based adhesives is prospected.
