Description

一种瓦楞纸基电热板
技术领域
本实用新型属于欧姆电阻发热器件，特别涉及一种以碳纤维纸基材上制备电热膜构成的瓦楞纸基电热板，适用于地面电采暖。
背景技术
目前常用绝缘板作基材，如玻璃，陶瓷，碳化硅类基材，或云母板和矿棉纸类薄型基材，表面掺杂面电热膜，外加薄层绝缘板保护，构成电热板，用于电热器件。其热效率较高，热惯性小，升温快，寿命长，可连续工作上万小时，成为其得到应用的突出优点。当用作地板采暖的电热板时，由于强度不够高，绝缘板出现破损，致使表面改性的电热膜外露，造成电量的流失或泄漏，影响使用安全。
发明内容
本实用新型的目的在于，设计制作一种瓦楞纸基电热板，利用瓦楞纸基绝缘板和纸基电热膜构成电热板，提高表面纸基绝缘板的粗糙度，简化电热膜的电路结构，以提高电热板强度，增加韧性，减少破损，保证使用安全。
本实用新型的技术方案是如下实现的，一种瓦楞纸基电热板，由电热膜和绝缘板组成，碳纤维纸基表面掺杂面电热材料，构成电热膜，电热膜呈平面条状，两端有镀铜电极，设有连接电极引线，电热膜上下两面胶结压固有电绝缘瓦楞纸基绝缘板，电热膜的电极引线外接有电源插头。
本实用新型的优点是，充分发挥现有电热膜器件的电热转换优越性能，电热板的热效率高达96％以上，热惯性小，散热面大，升温快，寿命长。电热板在预定条件下工作时，外部绝缘性能好，不起火，不损坏，具有可靠防水性能。电热膜与电绝缘瓦楞纸基绝缘板胶结压固，强度提高，韧性增强。电路连接方式简捷，提高了电路安全性。适用于制作各种电热器件，采暖地面的电热板，暖房中的采暖电热板，农用高温室内的电热设备。
附图说明
