摘要
采用熔融挤出法制备阻燃ACS树脂,研究了环保溴系阻燃剂、增韧剂种类及用量对阻燃ACS综合性能的影响。结果表明,低分子量溴化环氧树脂/三氧化二锑复配阻燃ACS树脂的综合性能损失较小,耐候性良好。ABS高胶粉的增韧效果优于氯化聚乙烯(PE-C),但所得增韧阻燃ACS的拉伸性能、弯曲性能降幅较大。PE-C具有协效阻燃作用,但热稳定性相对较差。PE-C增韧阻燃ACS树脂的阻燃性能达到UL 94 V-0级,综合性能良好。利用阻燃ACS注塑成型制得的导流管接头的综合性能完全符合技术指标要求,与原有阻燃抗静电ABS制件相比,加工成型性能相当,抗静电性能有所提高。
The flame-resistant ACS resin was prepared by melt extrusion, and the effect of different green brominated flame retardant and toughening agent content on the comprehensive performance of the flame-resistant ACS resin were studied, and though- ened with high rubber content ABS powder and chlorinated polyethylene respectively. The results showed that the flame-resistant ACS resin based on brominated epoxy oligomer（ BEO）/Sb2O3 exhibited better weatherability and less loss on comprehensive performance. ABS powder possessed better toughening effect on the ACS than PE-C, it made the tensile strength and flexural strength of ACS degradation, while PE-C had a better assistant flame retardance to the ACS resin. The flame-resistant ACS based on PE-C had desirable comprehensive performance and ootimal flame retardancy with flammability rating of UL 94 V - 0. The resulting flame-resistant ACS exhibited equivalent moldability and better antistatic property when compared with the flame-resistant ABS, and the joints for draft tube made from the flame-resistant ACS could meet the application requirements perfectly.
