摘要:
为改善淀粉的性能,提高淀粉膜的使用效果,通过对淀粉进行羟丙基磺酸基化变性处理,合成了羟丙基磺酸基化淀粉(HPSS)。以断裂强度和断裂伸长率为量化指标,考察了聚乙烯醇(PVA)品种和含量对PVA/HPSS复合膜增韧效果的影响。研究发现,PVA-0599、PVA-1788和PVA-1799分别与HPSS复合制膜后,复合膜的断裂强度降低,断裂伸长率明显提高,其中PVA-1799的增韧作用最好。随着复合膜中PVA-1799的质量分数从0%增加到50%,复合膜的断裂强度由28.9 MPa逐渐降低到15.9 MPa,断裂伸长率由4.1%逐渐增大到16.3%。综合考虑断裂强度和断裂伸长率,认为PVA-1799质量分数为30%~40%时复合膜性能较好。
Abstract:
To improve the property and the film usability of starch,the hydroxypropylsulfonated cornstarch(HPSS)is prepared by the starch hydroxypropylsulfonation. The effect of variety and mass ratio of the polyvinyl alcohol(PVA)on the toughness of PVA/HPSS composite films is studied by taking the film breaking strength and breaking elongation as the quantization index. It is found that,compared with that of the HPSS film,the breaking strength of the PVA-0599/HPSS,the PVA-1788/HPSS and the PVA-1799/HPSS decreases,while the breaking elongation remarkably increases,and the PVA-1799 shows the best toughening effect. As the mass ratio of the PVA-1799 increases from 0% to 50%,the breaking strength decreases from 28.9 MPa to 15.9 MPa,and the breaking elongation of the PVA-1799/HPSS increases from 4.1% to 16.3%. The resulting indicates that the preferable mass ratio of the PVA-1799 is 30%~40%.
