一种电热一体板及制备方法
技术领域
本发明涉及一种建材，具体涉及一种电热一体板及制备方法。
背景技术
目前我国南方冬季没有有效采暖措施，冬季寒冷潮湿；北方虽然有采暖措施，但采暖过程中对空气污染严重。随着环境污染和能源危机的日益严峻，国家目前正在大力推广煤改电，以便节能减排。但对于北方用户，集中供暖的方式使得用户在离开房屋时供暖设备依然在运行，能量损失严重；对于南方用户，目前缺少高效的采暖手段。
电热一体板是一款全新的采暖产品，通电后可发射5～15μm远红外线，5～15μm远红外线为生命光波，人体感应敏感且有具有红外理疗的作用，温暖舒适健康，能耗低，节能环保无污染。电热一体板采用一体化结构设计，集发热、保温和装饰三大功能于一体，安装方式多且安装灵活方便，可以用作室内地面、墙面以及屋顶。
本发明涉及电热一体板采用厚度小于10μm氧化物薄膜作为发热材料，不仅发热材料用量少，发热膜层生产成本低，而且采用氧化物作为发热材料，氧化物性能稳定，发热效率高，所以电热一体板使用寿命长，而且使用过程中发热功率稳定。
发明内容

优选的，上述发热膜层为碳氮化合物，所述发热膜层材料包括SiCxN(1-x)。
优选的，上述发热膜层上下两个表面设置有上绝缘防水层和下绝缘防水层；所述发热膜层表面两侧靠近边缘处附着有可导电的金属带作为供电电路，金属带与内置式电极电连接。
优选的，上述下绝缘防水层和上绝缘防水层材料为无机防水绝缘材料或有机防水绝缘材料；
所述无机防水绝缘材料包括陶瓷、瓷釉、玻璃、云母、石英和介电陶瓷；
所述有机防水绝缘材料包括聚酰亚胺、聚酰胺酰亚胺、聚酰亚胺、聚马来酰亚胺、聚二苯醚、改性环氧、不饱和聚酯和聚芳酰胺。
优选的，上述电热一体板还包括红外反射膜层，所述红外反射膜层可以位于基材和下绝缘防水层之间，所述红外反射层为含有金属的膜层。
优选的，上述保温基材的材料和尺寸满足抗压强度不小于10MPa，导热系数低于0.5W/(m·K)。
优选的，上述保温基材材料包括硅酸钙板、硅酸盐板、云母板、多孔陶瓷板和多孔陶瓷板中的一种或几种。
优选的，上述面层的材料莫氏硬度不小于3，耐磨性能不大于500mm3。
一种电热一体板的制备方法，包括如下步骤：
Step1：取保温基板，清洗干净并烘干；
Step2：在基材抛光表面采用真空镀膜法制备发热膜层，然后100～450℃退火10～120min；
Step3：在发热膜层表面设置金属导电带，并将金属导电带和内置电极电连接；
Step4：在发热膜层表面设置面层即完成低压电热板的制备。
本发明具有如下优点：
本发明的电热一体板及其制备方法，电热一体板采用厚度小于10μm氧化物薄膜作为发热材料，不仅发热材料用量少，发热膜层生产成本低，而且由于采用氧化物作为发热材料，氧化物性能稳定，发热效率高，所以电热一体板使用寿命长，而且使用过程中发热功率衰减小。
电热一体板采用真空镀膜制备发热膜层，不仅可以准确的控制发热膜层的厚度，而且真空镀膜可以精确控制发热材料的成分，可以有效对发热膜层的发热材料进行掺杂，一方面可以通过掺杂提高发热材料的红外线发射率，另一方面通过掺杂可以有效调节发热材料所发射红外线的波长进行，使电热一体板所发射红外线波长和人体吸收红外线相匹配。

参见图4，测试按照GB/T7287-2008进行，电热一体板额定电压220V，额定功率80W，采用氧化物作为发热膜层的电热一体板测试结果。
对比图3与图4中的测试结果，本发明的电热一体板及其制备方法，电热一体板采用厚度小于10μm氧化物薄膜作为发热材料，不仅发热材料用量少，发热膜层生产成本低，而且由于采用氧化物作为发热材料，氧化物性能稳定，发热效率高，所以电热一体板使用寿命长，而且使用过程中发热功率衰减小。
电热一体板采用真空镀膜制备发热膜层，可以准确的控制发热膜层的厚度，发热膜层厚度小于10μm，可以减小发热材料的用量，降低发热膜层成本。此外，真空镀膜后可以精确控制发热材料的成分，可以有效对发热膜层的发热材料进行掺杂，一方面可以通过掺杂提高发热材料的红外线发射率，另一方面通过掺杂可以有效调节发热材料所发射红外线的波长进行，使电热一体板所发射红外线波长和人体吸收红外线相匹配。
虽然，上文中已经用一般性说明及具体实施例对本发明作了详尽的描述，但在本发明基础上，可以对之作一些修改或改进，这对本领域技术人员而言是显而易见的。因此，在不偏离本发明精神的基础上所做的这些修改或改进，均属于本发明要求保护的范围。
