Study on Blending Modification of Waste Flame-Retardant HIPS Plastic
Physical modification was used in recycling of waste flame retarded HIPS (high impact polystyrene) plastics. Styrene butadiene rubber (SBR) and styrene-butadiene-styrene copolymer (SBS) being used as flexibilizer to toughen waste HIPS plastics was studied and the mechanical properties of modified plastic were analyzed in the experiment. The results showed that when the addition of SBS or SBR was 20% or 30%, the modified plastics had the maximum izod impact strength of 13.96 KJ/m2 and 11.86 KJ/m2 respectively, which increased 96.3% and 66.8%. Based on the optimal toughening formula, the influence of nano-organic montmorillonite (OMMT) on mechanical properties of modified plastic was studied further. The results showed that when the addition of OMMT was 6%, the mechanical properties enhanced notably.
