摘要
以POE-g-MAH为增容剂,应用双螺杆挤出机制备通过熔融共混法制备了PA6/ABS合金,研究了ABS树脂的用量对合金的力学性能的影响。结果表明:在POE-g-MAH存在的条件下,随着ABS用量增大,共混物的拉伸强度逐渐增大,简支梁缺口冲击强度则逐渐减小,而无缺口冲击强度先减小后增大。在混和体系中,POE-g-MAH具有增容和增韧的双重作用。
PA6/ABS alloy was prepared, POE - g - MAH used for compatibilizer, by the melt blending with the application of twin - screw extruder, and the effects of the amount of ABS resin on the mechanical properties of the alloy were studied. The results showed that： with the increasing amount of ABS under the existence of POE - g - MAH, the tensile strength of the blend was gradually increased, and Charpy notched impact strength gradually decreased and non -notched impact strength decreased firstly and then increased. In the mixed system, POE -g -MAH played the dual role of compatibilizer and a toughening regeant.
