| 中文摘要: |
| 通过熔融共混法制备用于包覆丙烯腈-丁二烯-苯乙烯共混物（ABS）的热塑性聚氨酯弹性体（TPU），研究TPU流动性和硬度对其与ABS之间粘合强度的影响以及硅酮粉用量、光稳定剂HA10/紫外线吸收剂UV-P/抗氧剂1010体系和抗氧剂1098/168/626体系对TPU耐磨性能和耐老化性能的影响。结果表明：TPU与ABS之间的粘合强度随着TPU熔融指数增大而增大，随着TPU硬度增大先增大后减小，当TPU的邵尔A型硬度为85度时，粘合强度达到最大，为16 N·m-1；硅酮粉可以提高TPU的耐磨性能，光稳定剂HA10/紫外线吸收剂UV-P/抗氧剂1010体系可以使TPU灰度等级小于4的试验时间延长至380 h，抗氧剂1098/168/626体系可以有效提高TPU的耐磨性能和耐老化性能。 |
| 英文摘要: |
| The thermoplastic polyurethane elastomer（TPU）for coating acrylonitrile-butadiene-styrene copolymer（ABS） was prepared by melt blending method，the effect of the fluidity and hardness of TPU on the adhesion strength between TPU and ABS and the effect of silicone powder amount，light stabilizer HA10/ultraviolet rays absorber UV-P/antioxidant 1010 system and antioxidant 1098/168/626 system on TPU wear resistance and aging resistance were investigated.The results showed that，the adhesion strength between TPU and ABS was increased with the increase of TPU melt index，and increases first and then decreases with the increase of TPU hardness.When the Shore A hardness of TPU was 85 degrees，the adhesion strength reacheed the maximum，which was 16 N·m-1.The silicone powder could improve the wear resistance of TPU，the light stabilizer HA10/ultraviolet rays absorber UV-P/antioxidant 1010 system could make the test time that the TPU gray level was less than 4 extend to 380 h，and the antioxidant 1098/168/626 system could effectively improve the wear resistance and aging resistance of TPU. |
