摘要: 基于2-甲基-2,5-二氧-1,2-氧磷杂环戊烷(OP)的环状酸酐结构和可以通过水解或醇解开环的特点,对OP/对苯二酚/环氧树脂预聚体的反应可行性、固化过程以及阻燃性能进行了研究;成功制备了含磷环氧树脂,固化12 h后的环氧树脂具有良好的阻燃性能,极限氧指数(LOI,%)为25.7%,垂直燃烧测试达到UL-94 V-0级别。

关键词: 环氧树脂, 2-甲基-2, 5-二氧-1, 2-氧磷杂环戊烷, 对苯二酚, 阻燃性能

Abstract: Based on the structure of 2-methy-2,5-dioxo-1,2-oxaphospholane(OP)which are cyclic estolide structure,and the ring can be opened through hydrolysis or alcoholysis,studies the reaction feasibility,solidification process and flame retardancy of OP/hydroquinone/epoxy preformed polymer;successfully prepares the epoxy containing phosphorus,the epoxy has good flame retardancy after solidifing 12 h,the limited oxygen index is 25.7%,the calmet burning test reaches UL 94 V-0 grade.

Key words: epoxy, 2-methy-2, 5-dioxo-1, 2-oxaphospholane, hydroquinone, flame retardancy
