DOPO衍生物阻燃性能研究
Research on Flame Retardancy of DOPO Derivative
摘要
Abstract
Phosphorus-containing organic compounds such as DOPO have several advantages including high flame-retardant efficiency, low production of corrosive and toxic gases in flames etc. In this work, a novel DOPObased siloxanes were evaluated as halogen-free flame retardants for epoxy resins. The cured epoxy resins exhibited better thermal stabilities and greatly improved flame retardant properties due to the presence of phosphorus-containing siloxanes. The cured epoxy resins with phosphorus loading of 2. 0 wt％ showed LOI values of 32-33 and achieved UL94 V-O ratings. Silicon and phosphorus demonstrated a synergistic effect in the flame retarding behavior of the resins.关键词
