耐黄变聚乙烯醇缩丁醛树脂及其制备方法

Anti-yellowing Polyvinyl Butyral Resin and Preparation Method

文章介绍了一种耐黄变聚乙烯醇缩丁醛树脂的制备方法。这种耐黄变聚乙烯醇缩丁醛树脂在200℃的电热恒温鼓风干燥烘箱内烘烤1 h仍不发黄,具有抗老化性能和热稳定性能好的优点,为聚乙烯醇缩丁醛树脂及胶片生产企业的技术进步提供参考。

In this paper,a preparation method of anti-yellowing polyvinyl butyral(PVB)resin is introduced.The anti-yellowing PVB resin was baked in the dry oven with electric heating constant temperature blower at 200℃after 1h and still remained unyellowing.It has the advantages of anti-aging performance and good thermal stability,providing a reference for the technological progress of PVB resin and f ilm production enterprises.
