摘　　要：对甘油锌用作聚氯乙烯(PVC)光稳定剂的光稳定作用进行了研究,考察了PVC紫外光老化后力学性能和颜色的变化。结果表明,甘油锌对PVC具有明显的光稳定作用,与受阻胺光稳定剂Tinuvin770复配时,具有明显的正协同效应,当二者的配比达到2∶3(质量比,下同)时,对PVC的光稳定效果最佳。Glyzinc was used as a light stabilizer of PVC, and its effect on the after-aging mechanical properties and color of PVC was investigated. It showed that the photostabilization of glyzinc on PVC was excellent, and a synergistic effect of glyzinc with Tinuvin770 was observed. When the weight ratio of glyzinc to Tinuvin770 was 2 ： 3, the photostabilization was the best.
