聚氯乙烯/杨木粉模压发泡材料的制备及性能研究

目的制备聚氯乙烯杨木粉发泡材料并研究其性能。方法采用模压法制备发泡材料,利用压缩试验表征其性能。结果随着杨木粉填充量的增加,聚氯乙烯杨木粉发泡材料的密度呈上升趋势。添加木粉后,压缩强度呈先升高后下降的趋势,当木粉填量为10份时,压缩强度达到最大。随着木粉粒度的增加,聚氯乙烯木粉发泡材料压缩强度也呈先上升后下降的趋势,在木粉粒度为100目时压缩强度达到最大。结论可采用模压法制备聚氯乙烯杨木粉发泡材料,发泡剂用量、木粉填量和粒度对发泡材料性能有一定影响。

Preparation and Properties of PVC/Poplar Powder Composite Foam by Moulding Method

The PVC/Poplar powder composite foam was prepared and its properties were investigated. The moulding method was used to prepare the composite foam, and the compressive test was used to characterize the properties of the composite foam. The density of the composite foam was increased as the filling content of poplar powder was increased. The compressive stress was increased firstly then decreased as the filling content of poplar powder was increased. When the content of poplar powder was 10 portions, the compressive stress was the maximum. The compressive stress was increased firstly then decreased as the mesh number of poplar powder was increased. When the mesh number was 100 meshes, the compressive stress was the maximum. The moulding method can be used to prepare the PVC/Poplar powder composite foam. The properties of composite foam were influenced by the content of AC foaming agent, the filling content and the mesh number of poplar powder.
