【摘要】 <正>在PC片材微孔发泡时,发泡加工窗口的调控对其发泡和性能有重要的影响。为了调控PC片材的微孔发泡窗口,本文采用环保无毒的柠檬酸三正丁酯(TBC)增塑剂对PC片材增塑,增加了PC分子链的运动性和片材可塑性,在低于其玻璃化温度用模压法对PC片材进更多还原

【Abstract】 The influence of processing parameters on the mechanical properties of plasticized microcellular polycarbonate sheet has been investigated.The result showed that with the decrease of apparent density,the yield point of stress-strain curves was gradual unconspicuous and even disappeared,and meanwhile,tensile strength of the microcellular PC decreased.The tensile modulus of the plasticized PC decreased gradually when foaming temperature increased,while tensile strength and tensile modulus both decreased when the relative content of the plasticizer decreased.更多还原
