【摘要】：采用注射成型工艺和微粒浸出技术成功制备了碳纤维填充低密度聚乙烯(PE-LD/CF)多孔复合材料,其具有自限温性能且不含金属成分,用作电子烟烟弹可以有效消除传统电子烟线圈浸出的重金属离子和丙二醇受热氧化产生的有毒羟基化合物的危害。研究结果表明,PE-LD/CF多孔复合材料仅仅是CF和PE-LD的简单混合物,其主要孔隙直径约为1~2μm,有效孔隙率为23.79%。PE-LD/CF多孔复合材料具有明显正温度系数(PTC)效应且PTC强度约为1.82,其自发热最高温度为68.4℃,且其加载尼古丁后自发热最高温度(43.5℃)远低于丙二醇溶液沸点(132℃),理论上可以消除传统电子烟产生的羟基化合物的危害,其尼古丁释放浓度能在较长时间内保持稳定且释放量约为1.6μg/m L。结果表明,这种多孔复合材料可以取代传统电子烟烟弹。
[Abstract]:Carbon fiber filled low density polyethylene (LDPE) / PE-LD- / CFC porous composites were successfully prepared by injection molding and particle leaching technology. The toxic hydroxyl compounds produced by thermal oxidation of propylene glycol and heavy metal ions leached by conventional electronic smoke coil can be effectively eliminated by using electronic smoke bomb. The results show that the porous composite of PE-LDR / CF is only a simple mixture of CF and PE-LD. The main pore diameter is about 1 渭 m, the effective porosity is 23.79 and the PE-LD- / CF porous composite has the effect of positive temperature coefficient and PTC strength is about 1.82, the highest temperature of self-heating is 68.4 鈩，
