摘要:
以环氧树脂为基材，以导电碳黑为填料，制备了具有正温度系数特性（PTC）的热固性导电复合材料.探讨了固化剂的种类，环氧树脂基体的种类等对环氧树脂基导电复合材料PTC特性的影响．当以E51为基体树脂，以VXC200为导电碳黑，树脂和碳黑用量相同时，不同种类固化剂制备的环氧树脂基导电复合材料的PTC强度不同，其中当固化剂为甲基六氢邻苯二甲酸酐时，所得的导电复合材料的PTC强度最大.当以环氧树脂E51为基材，以甲基四氢邻苯二甲酸酐为固化剂，以导电碳黑VXC200为导电填料制备的环氧树脂基导电复合材料具有很高的PTC强度，阻值随温度变化在130℃附近发生阶跃性变化,由2.7欧姆上升到几百欧姆，温度恢复到室温时，阻值恢复到初始值附近，具有可恢复性.
Abstract:
The thermosetting conductive composites were prepared with epoxy as base resin and conductive black as filler. The effects of curing agents and epoxy resins on the positive temperature coefficient (PTC) characteristic of the epoxybased conductive composites were discussed. When the contents of base resin and conductive black are same, the values of PTC strengh prepared with the different curing agents are different. The highest PTC strengh can be obtained when methyl tetrahydro phthalic anhydride is used as the curing agent. In the case of epoxy resin E51 as a matrix, methyl tetrahydro phthalic anhydride as a curing agent, VXC200 conductive carbon black as a conductive filler, the asprepared conductive epoxy composites have high PTC strength. The electrical resistance of the composites is changed sharply from 2.7 ohms to hundreds of ohms at about 130 ℃. Moreover, the composites return to the initial state with the lower electrical resistance when the temperature is decreased to room temperature.
