水滑石的合成及其在PVC中的应用研究进展

摘要

Hydrotalcite is one kind of layered double hydroxides. Because of its special crystal chemical property, hydrotalcite has good thermal stability, adsorption, and anionic exchangeable property. Due to these properties, hydrotalcite finds many applications in varied fields such as chemical industry, material, environmental protection and medicine. The synthesis methods with advantages and disadvantages, the application advance of hydrotalcite in PVC were introduced in this paper. At the end, the development direction of hydrotalcite in PVC was pointed out.%水滑石是一种层状双羟基复合金属氧化物,因其特殊的晶体化学性质,故有良好的热稳定性、吸附性和离子交换性,广泛应用于化工、材料、环保和医药等领域.本文重点介绍了水滑石的合成方法及其优缺点,水滑石在PVC中的应用进展,以及水滑石作为PVC热稳定剂的优异性能,并指出了今后的发展方向.
