| 摘 要： | 采用乳液共混法制备了淀粉/丁苯橡胶(SBR)以及间苯二酚甲醛树脂(RF)改性淀粉/SBR复合材料,考察了偶联剂对2种复合材料硫化特性、力学性能的影响,并用扫描电镜观察了其相态结构。结果表明,各种偶联剂都能在一定程度上提高淀粉/SBR复合材料的拉伸强度和撕裂强度,其中γ-氨基丙基三乙氧基硅烷(KH-550)和N-β(氨基乙基)-γ-氨丙基三甲氧基硅烷(KH-792)的增强效果最为显著;采用RF对淀粉进行改性,RF改性淀粉/SBR复合材料的力学性能较之淀粉/SBR复合材料的力学性能有了进一步提高。橡胶相与淀粉相界面结合的改善是RF改性淀粉/SBR复合材料力学性能提高的主要原因。

| Abstract: | Starch/styrene-butadiene rubber(SBR) and starch modified with resorcinol-formaldehyde(RF)/SBR composites were prepared by latex compounding method.Effects of coupling agents on curing characteristics and physical-mechanical properties of the two kinds of composites were investigated,and the morphological structure of the composites were observed by scanning(electron) microscope.The results showed that six coupling agents such as NDZ-105,Si 69,A-151,KH-570,KH-550 and KH-792 could improve the tensile strength and tear strength of starch/SBR composites,especially aminosilane coupling agents KH-550 and KH-792 showed the strongest reinforcement.Compared with starch/SBR composites,starch modified with RF/SBR composites exhibited better physical-mechanical properties,which should be attributed to the enhanced interfacial strength. |
