PVC水滑石类热稳定剂研究进展

The Research progress of LDHs heat stabilizer of PVC

水滑石（LDHs）是一种新型的热稳定剂，其特殊的化学组成决定了其对HCl具有吸收作用，而且其特殊的层状结构可以对其进行层问有机阴离子嵌入改性。将其用于聚合物PVC中，可以起到阻止PVC热分解的作用。文中综述了水滑石稳定剂的制备性能和稳定机理。

LDHs is a new type of heat stabilizer, its special chemical composition makes it absorb HCI ,and its special laminated structure could be inserted in the organic anion to modify its interlamellar behaviour. When used in the polymer PVC, it can play a role in preventing PVC thermal decomposition. It was summarized the preparations, properties and stabilization mechanism of LDHs.
