在本实施例中，所述金属板保护层2还有一个功能，由于所述金属板保护层2设置在电热膜发热层3与瓷砖层1之间，所述金属板保护层2可以对位于金属板保护层2内侧的电热膜发热层3进行防护，在本申请中所述瓷砖层1外壁为朝向室内的一面，所述瓷砖层1的内壁为瓷砖层1朝向地面的一面，即瓷砖层1与金属板保护层2接触的侧壁；当所述瓷砖层1外壁受到冲击力，造成瓷砖层1的内壁出现小幅度崩裂时，不会让瓷砖层1的碎片造成电热膜发热层3出现损坏，造成防雷发热瓷砖整体失效的情况发生；
作为本实施例中一种优选的实施方式，所述瓷砖层1包括瓷砖11和瓷砖底面导热涂层12；所述瓷砖底面导热涂层12涂覆于瓷砖11的内壁，所述瓷砖11涂覆瓷砖底面导热涂层12的一侧与金属板保护层2接触连接；
所述金属板保护层2包括金属板21和金属板底面导热涂层22，所述金属板底面导热涂层22涂覆于金属板21远离瓷砖11的一侧，所述金属板21涂覆金属板底面导热涂层22的一侧与电热膜发热层3接触连接；
在本实施例中，所述金属板底面导热涂层22和瓷砖底面导热涂层12采用绝缘防水、导热能力好、附着力强的涂料；
所述金属板21材质为镀锌钢板、钢板、不锈钢板、铝板、合金板中的任意一种，金属板21厚度为0.2mm~2.0mm，金属板21表面电阻＜2Ω；所述金属板底面导热涂层22和瓷砖底面导热涂层12提高防雷发热瓷砖的隔音降噪、保温性能，提升热能利用效率；
作为本实施例中一种优选的实施方式，所述电热膜31采用石墨烯电热膜、碳晶电热膜、金属丝电热膜、碳纤维电热膜中任意一种；
所述电热膜31与外壳5之间还设有热辐射反射层4，所述热辐射反射层4设于电热膜31远离金属板保护层2的端面，所述热辐射反射层4减少热量从电热膜31远离瓷砖层1的一侧散发，让热量集中向瓷砖层1的外壁散发；
防雷的电热瓷砖的制备方法包括以下几个步骤：
S1、瓷砖11和金属板21的导热涂层预制备
准备好瓷砖11、金属板21和绝缘导热涂料，将瓷砖11底面（紧贴金属板21面）和金属板21底面（紧贴电热膜31面）朝上，在瓷砖11和金属板21底面全面喷涂无水清洁剂，清洁剂静置保留1~2分钟，然后用高压空气喷枪吹喷瓷砖11底面和金属板21底面，进行空气干洗，然后进行烘烤，烘烤温度为80~100℃，然后将他们放置到室温，然后用喷枪将绝缘导热涂料全部涂覆喷瓷砖11底面和金属板21底面，涂覆完，将它们推入温度为100~120℃的烘烤房烘烤，进一步得到具有底面带有绝缘高导热涂层的瓷砖11和金属板21，完成瓷砖底面导热涂层12和金属板底面导热涂层22的制备；
S2、金属板保护层2、电热膜层3及热辐射反射层4、防雷模块的制备
将电热膜31、S1中完成涂覆涂层的、第一防雷模块34、第二防雷模块35和热辐射反射膜4准备好，将金属板21置于最底层，将设有金属板21底面导热涂层22一面朝上，并在上面铺上电热膜31和热辐射反射膜4；
然后进一步将第一防雷模块34和第二防雷模块35放在热辐射反射层4远离电热膜31端面适当位置，将火线与零线各连接一组防雷模块，第一防雷模块34通过导线接入与电源输入端快速连接器32火线导线，第二防雷模块35所述通过导线接入与电源输入端快速连接器32连接的零线导线，第一防雷模块34和第二防雷模块35的接地线及电源接地线的一端都焊接在金属板21上，该连接点和电热膜电源线接入点、防雷模块引线与火线、零线的连接点均用阻燃耐温防水绝缘胶进行封固，进一步用阻燃耐温防水绝缘胶在每层与层的边缘进行封胶，使金属板保护层2、电热膜发热层3、热辐射反射层4、第一防雷模块34和第二防雷模块35形成一个组件；
S3、瓷砖与组件进行组合
将S1制备的瓷砖11与S2制备的组件进行组合，按自下而上的顺序，放置涂层瓷砖，瓷砖11上设有瓷砖底面导热涂层12的端面朝上，然后在其上面对齐放上S2制备的组件，金属板保护层2与瓷砖11的涂层面紧贴，紧贴四周边缘用阻燃耐温绝缘防水胶粘贴封固，自此得到一个功能组件主体；
S4、功能组件主体与阻燃防水绝缘外壳的压合
将S3制备的功能组件主体放入发泡钢模具中，瓷砖11外壁朝下，通过模具设置的线凹槽将电源输入端快速连接器32和电源输出端快速连接器33牵出至模具外，然后在模具中注入阻燃防水保温绝缘的材料，合上模具上盖，待其发泡完毕后从钢模具中取出，就此得到一块具有阻燃防水保温的防雷防漏电电热瓷砖。
