PA/ABS合金力学性能的提升
|
摘要
通过改变树脂种类以及调控PA和ABS的树脂比例对PA/ABS合金材料的力学性能进行了提升。对不同比例的PA/ABS合金进行拉伸强度、弯曲模量以及缺口冲击强度等性能测试分析,通过扫描电子显微镜观察不同合金材料的微观形貌,并对材料结构-性能之间的关系进行进一步分析。研究结果发现,与黏度较低的PA树脂相比,采用高黏度的PA树脂制备得到的合金材料具有更加优异的力学性能。在此基础上,向黏度较高的PA树脂中同时引入丁二烯含量不同的2种ABS树脂能对合金材料的力学性能具有有效的调控作用,当PA∶ABS=50∶45,且ABS树脂中高丁二烯含量的POW HR181树脂含量为25%时,合金材料达到最佳的刚韧平衡。
The mechanical properties of PA/ABS alloy were improved through adjusting resin variety and PA/ABS ratio.Tensile strength,flexural modulus and Izod notched impact strength of PA/ABS alloys with different resin ratio were tested and analyzed. The microstructures of different PA/ABS alloys were observed with electron scanning microscopes and the relationship between the structure and property was further investigated. The results showed that the better mechanical properties could be achieved for PA/ABS alloy prepared with high-viscosity PA. Meanwhile,mechanical properties could be effectively adjusted through the blending the PA of high viscosity with two kinds of ABS with different butadiene contents. The stiffness and toughness could be well balanced with the PA/ABS ratio of 50∶ 45,in which the amount of POW HR181 with high butadiene content was 25%.
