Research on Application of Novel Liquid Na/Zn Thermal Sstabilizer in Poly(vinyl chloride)

doi:10.19491/j.issn.1001-9278.2013.03.014

Abstract

Abstract: A highly efficient and low cost novel liquid Na/Zn thermal stabilizer was developed in this work. Its application in poly(vinyl chloride)(PVC) was investigated by Heat aging test and conductivity test. In comparison with blank PVC, the thermal stability time of PVC films was extended to 50 min though adding Na/Zn thermal stabilizer at a Na/Zn mass ratio of 1/1. The dynamic thermogravimetric analysis also confirmed that the Na/Zn stabilizer presented an obvious improvement of stability on thermal degradation. Besides, the Na/Zn stabilizer provided soft PVC with excellent mechanical properties.

Key words: poly(vinyl chloride), sodium/zinc thermal stabilizer, thermal stability, mechanical property
