氧化-双重醚化改性淀粉/PVA的复合膜性能及其黏合性的研究
|
摘要
为提高氧化木薯淀粉(OTS)的使用性能,在碱性条件下,以3-氯-2-羟丙基磺酸钠和3-氯-2-羟丙基三甲基氯化铵为醚化剂,与OTS反应制备了氧化-双重醚化改性木薯淀粉(ODES),使用傅里叶变换红外光谱(FTIR)对其进行了表征分析,并研究了共混比对其与聚乙烯醇(PVA)复合材料的薄膜、黏合等性能的影响规律。结果表明,PVA与ODES共混对复合膜的性能具有显著的影响,膜的断裂伸长率分别由PVA与ODES共混质量比0∶100的3. 37%提升到80∶20的134. 4%,断裂强度逐渐降低,表明复合膜具有良好的柔韧性;共混后对棉和聚乳酸粗纱的黏合性能得到了显著提升。
To improve the performance of oxidized tapioca starch( OTS), oxidized and doubly etherified starch( ODES) was prepared by the reaction of OTS with sodium 3-chloro-2-hydroxypropyl sulfonate and 3-chloro-2-hydroxypropyl trimethyl ammonium chloride under alkaline condition. The ODES granules were analyzed by Fourier transform infrared( FTIR) spectroscopy. The influence of blending ratio on the properties of composite film and adhesion of the ODES/polyvinyl alcohol( PVA) was investigated.The results show that the blending of PVA and ODES has a significant effect on the properties of the composite films. When the blending ratio of PVA and ODES changes from 0 ∶ 100 to 80 ∶ 20,the breaking elongation of the films increases from 3. 37% to 134. 4%. The breaking strength of the films decreases gradually,which indicates that the ODES/PVA composite films have good flexibility. The adhesion exhibits an obvious improvement after the blending.
