镁铝水滑石的制备与性能研究

Abstract

Abstract: Mg-Al-hydrotalcite was prepared by saline-alkaline co-precipitation method.The synthesized samples were analyzed and characterized by XRD，FT-IR，and particle size analysis.The effects of Mg-Al-hydrotalcite stabilizer on the static thermal aging property and static thermal stability of PVC were investigated by static thermal aging test and static thermal stability test.Results showed that Mg-Al-hydrotalcite was a good thermal stabilizer and a good thermal aging stabilizer for PVC. The best proportion of thermal stability test among PVC，stearic acid，and Mg- Al-hydrotalcite was 100∶2∶1.2（mass ratio）.The best proportion of thermal aging test for PVC，DOP，stearic acid，and Mg-Al-hydrotalcite was 100∶70∶2∶2（mass ratio）.

Key words: co-precipitation method；Mg-Al-hydrotalcite, characterization；thermal aging property；thermal stability
