摘要
国外实验研究已经证明 ,利用PVC/纤维素纤维复合材料能够产生微孔发泡结构 ,但发泡率较低。多种因素如PVC、纤维素纤维的改性处理、加工条件等都将影响泡孔形态与制品的物理机械性能。本文针对PVC/木纤维复合材料 ,研究材料中增塑剂含量、表面改性处理、发泡时间、发泡温度等条件对发泡率、泡孔形态及制品物理机械性能的影响 ,以建立加工条件、泡孔形态、制品性能之间的关系。
Foreign experimental investigation has successfully demonstrated the feasibility of developing microcellular structures in PVC/cellulose-fiber composites,but a higher void fraction could not be achieved.Many factors such as the surface modification of PVC matrix and cellulose-fiber,processing conditions all affected the cell morphology and physical properties.Aimed at PVC/cellulose-fiber composites,the effect of conditions such as the content of plasticizer in polymer matrix,surface modification of wood fiber,foaming time and foaming temperature on foamability,cell morphology and physical properties of the product were studied,so as to make clear relationships of processing conditions,cell morphology and mechanical properties.
