摘要
Abstract
In this study,flame-retardant reinforced PBT compounds were prepared through a multi-component combina-tion of halogen flame retardants with phosphorus,nitrogen,and phosphorus-nitrogen-based flame retardants,and their glow-wire ignition temperature(GWIT)was investigated.Brominated polystyrene,antimony trioxide,diethylalumi-num hypophosphate,melamine cyanurate,melamine polyphosphate,and carbon-based composite halogen-free flame re-tardant were used as flame retardants to compound with the reinforced PBT for flame-retardant experiments.The en-hanced PBT compound only with halogen flame retardant or with halogen-free flame-retardant system cannot meet the re-quirements of IEC60335-1 for the GWIT of current carrying components in unmanned electrical appliances.By a combi-nation of different types of flame retardants and the use of bromine-nitrogen-phosphorus synergistic flame retardant,the enhanced PBT could ultimately achieve the best flame-retardant performance and simultaneously meet the requirements of flame-retardant standard at GWIT>825℃,GWFI>960℃,and UL 94 V-0.关键词
