亚磷酸酯类抗氧剂与氧化锑的反应变色研究

Study on the color change of reaction between phosphite antioxidant and antimony oxide

本文研究了亚磷酸酯类辅助抗氧剂168、608和H10的加入对溴锑阻燃体系尼龙颜色的变化规律。研究结果表明,亚磷酸酯类抗氧剂和氧化锑的同时加入会使材料变色。不同磷含量的抗氧剂对材料变色的影响程度不一,而溴系阻燃剂的加入对整个变色有抑制作用。

This article studied the color change of nylon in the bromine antimony flame retardant system with the ad-dition of phosphite ester auxiliary antioxidants 168,608,and H10.The research results indicate that the simultane-ous addition of phosphite antioxidants and antimony oxide will cause the material to change color.The impact of an-tioxidants with different phosphorus contents on material discoloration varies,while the addition of brominated flame retardants has an inhibitory effect on the overall discoloration.
