| 中文摘要: |
| 研究废旧轮胎胶粉(GTR)粒径和用量以及相容剂种类和用量对GTR/聚苯乙烯(PS)共混物性能的影响。结果表明：GTR可以改善PS的脆性，提高PS的抗冲击性能，但会使拉伸性能降低；GTR粒径越小，GTR/PS共混物的抗冲击性能越好；相容剂乙烯-丙烯酸酯-甲基丙烯酸缩水甘油酯和苯乙烯-丁二烯-苯乙烯嵌段共聚物(SBS)能大幅改善GTR/PS共混物的抗冲击性能，相容剂马来酸酐接枝聚丙烯以及甲基丙烯酸甲酯、丁二烯和苯乙烯的三元共聚物对GTR/PS共混物的抗冲击性能改善不大；GTR（粒径为75 μ m）/PS/相容剂SBS用量比为40/100/10时，GTR/PS共混物的综合性能较好，缺口冲击强度达到4.87 kJ·m-2。 |
| 英文摘要: |
| The effect of particle size and addition level of ground tire rubber(GTR),and the type and addition level of compatibilizer on the properties of GTR/polystyrene(PS) blend was investigated.The results showed that,GTR could improve the brittleness of PS and increase impact resistance property,but decrease tensile property of PS.The smaller the particle size of GTR was,the better the impact resistance property that GTR/PS blend had.Compatibilizer GMA and SBS could improve the impact resistance property of GTR/PS blend significantly，while PP-g-MAH and MBS had only a little effect.When the mass ratio of GTR(particle size was 75 μ m)/PS/SBS was 40/100/10,GTR/PS blend had excellent comprehensive properties,and the impact strength of GTR/PS blend reached 4.87 kJ·m-2. |
