聚氯乙烯—稀土稳定剂复合物的加工和使用性能的研究

Study on the Processing and Application Properties of Rare Earth Stabilized Polyvinyl Chloride Compounds

本文报道聚氯乙稀(PVC)与几种合成的稀土稳定剂组成的复合物的加工性能、力学性能与普通 PVC 稳定剂相比,所实验的稀土稳定剂能使复合物塑化速率加快、挤出产率提高,材料强度、韧性和光稳定性改善,而复合物熔体粘度有所增大。

This Paper deals with the processing and application properties of thePVC compouds stabilized with synthetic rare earth stabilizers.With compari-son of conventional stabilizers,the tested rare earth stabilizers may accele-rate the plasticizing rate of the compound raise extrusion output and improvestrength toughness and light stability of the material,but make some increasesof melt viscosity.
