EFFECT OF CURING AGENTS AND CURING CONDITIONS ON INTERCALATION AND EXFOLIATION BEHAVIOR OF EPOXY/CLAY NANOCOMPOSITE

Department of Polymer Science and Engineer, Zhejiang University,Hangzhou 310027,China

摘要: 本文作者选用了5种不同类型的胺类固化剂:二乙烯三胺(DETA),二氨基二苯基甲烷(DDM),2.4.6三(二甲氨基甲基)苯酚(DMP-30),增韧改性胺和低温固化改性胺。考察了固化剂类型,固化温度和时间对环氧树脂/粘土纳米复合材料插层剥离行为的影响。固化程度和粘土层间距分别采用FT-IR和XRD,TEM检测。结果表明:环氧/粘土的插层与剥离行为与所选用的五种固化剂类型关系不大,而主要取决于固化工艺参数。在合适的固化条件下,当环氧树脂在粘土层间的固化速度大于层外固化速度,达到基本固化时,就能实现粘土的剥离,得到环氧/粘土纳米复合材料。

Abstract: Effects of curing agents and curing conditions on the intercalation and exfoliation behavior of epoxy/clay nanocomposites were investigated. Five curing agents used were DETA,DDM,DMP-30 and two modified amines. The curing degree and distance between layers of the clay were measured by FT-IR , XRD and TEM respectively. It was found that epoxy resin is easy to intercalate the clay,but clay exfoliation in epoxy resin was dependent more on the curing conditions than on the curing agents. When the curing speed of epoxy resin interlayers is faster than that of extralayers and fully reaches curing, exfoliation easily takes place, and epoxy/clay nanocomposites can be prepared.
