摘要

The addition of a small quantity of nanoclay (3 wt%) can greatly enhance the efficiency of low profile additives (LPAs) on volume shrinkage control of low profiled unsaturated polyester (UP)/styrene (St) /LPA systems. In this study, the effect of nanoclay on volume shrinkage of low profiled UP resins containing polystyrene, poly(methyl methacrylate) and poly(vinyl acetate) respectively has been investigated by an integrated approach of static phase characteristics of uncured resin mixture, morphology of the cured samples, reaction kinetics, and shrinkage measurement. The results revealed that nanoclay greatly increased the fraction of LPA-rich phase, leading to a more micro-cracking in the LPA-rich phase or at the interface of the LPA-rich and UP-rich phases, and therefore an prominent improvement of volume shrinkage control. The effect of structure/properties of low profile additives and surface property of nanoclay on shrinkage of UP resin were also investigated.
