Abstract
The phenolic resin,PA6 and PPO were used as multiple charring agent to flame HIPS with the micro-capsulated red phosphorus together.In order to improve the flame retardant effect,mixture uniform design was used in the optimization of flame retardant conditions by preparing HIPS flame retardant composites.The limiting oxygen index as appraisal standard,mathematical model was established,which revealed the relationship among the MRP,PF,PA6 and PPO.Based on the analysis of the empirical model,the optimized parameters had been obtained,the limiting oxygen index was up to 30 %.Experimental results showed that the MRP with phenolic resin,and PPO was superior for flaming retardant HIPS.
