摘要
分别以苯乙烯丁二烯苯乙烯共聚物(SBS)和乙烯辛烯共聚物(POE)为增韧剂,研究了它们对阻燃高抗冲聚苯乙烯(HIPS)物理机械性能和阻燃性能的影响.结果表明:以SBS为增韧剂所得复合材料的综合性能优于以POE为增韧剂所得复合材料的综合性能;复合材料的冲击强度随SBS用量的增大而增大,当SBS用量为12%时,其冲击强度达到8 kJ/m2左右,较未经增韧改性复合材料的冲击强度增加了6 kJ/m2左右,并且SBS的加入不会对复合材料的阻燃性能产生不利影响.
Mechanical and flaming properties of flame retardance high impact polystyrene of modified by SBS or POE are studied. The results show that comprehensive properties of composite of containing SBS are better than those of containing POE, impact strength of composite is increased with SBS amount being raised. When SBS amount is 12 %, impact strength of composite about reaches 8 kJ/m^2, which about increases 6 kJ/m^2 on the base of former impact strength, flame retardance properties of composite of containing SBS are not influenced.
