Halogen-free flame retardant reblending system for glass fiber reinforced nylon and its use in halogen free flame retardant glass fiber reinforced nylon materials

摘要

This invention discloses a halogen-free flame retardant mixture system for glass fiber reinforced nylon, of which the raw material composition by weight percentage comprises: aluminum diethylphosphinate 40-90%, aluminum orthophosphite 8-30%, melamine metal phosphite 1∼20% and zinc stannate 1∼10%. This invention discloses a halogen-free flame retardant mixture system for glass fiber reinforced nylon, which has the benefits of high fire resistance, no migration and no corrosion of equipment etc., overcoming the shortcomings of the phosphorus-nitrogen mixture flame retardant system based on aluminum diethylphosphinate applied to glass fiber reinforced nylon material in the prior art, which can adapt to the glass fiber reinforced nylon material system to obtain comprehensively excellent halogen-free flame retardant glass fiber reinforced nylon material.
