Study on Halogen-free Nitrogen and Phosphorus Flame Retardant TPS Composites
Using hydrogenated styrene-butadiene block copolymer(SEBS)/white oil/ethylene-oc-tene copolymer(POE)/polypropylene(PP)as the base material,and ADP/MCA halogen-free flame retardant was added.The halogen-free flame retardant SEBS composite was prepared by adjusting the flame terardant ratio,and the flame retardancy and mechanical properties of TPS composite were stud-ied.The results showed that with the increase of flame retardant content,regardless of the change in flame retardant ratio,the mechanical properties of the material showed a downward trend,and there was a linear relationship between the decrease in mechanical properties of the compound and the in-crease in flame retardant content.When the ratio of ADP/MCA was 1.5:1,and the content of flame retardants reached 40％,the composite flame retardants achieved the best flame retardant effect.
