Comparison Study of Four Aluminum Phosphinates Filled Flame-retardant Epoxy

摘要

Epoxy resins (EP) hold an important position in polymer materials[1],while dialkylphosphinate salts belong to newly developed phosphorus-containing fire retardants[2].Difference in structure of alkyl group attached on phosphorus atom will cause a difference in properties of phosphinate salt itself,which will cause a variation of performance for polymer composites.In this study,the compared investigation of four aluminum dialkylphosphinates filled EP composites was carried out:aluminum methylethylphosphinate (Al (MEP)),aluminum diethylphosphinate ((A;(DEP)),aluminum methylbutylphosphinate (A;(MBP)) and aluminium methylcyclohexylphosphinate (Al(MHP)).
