Description

石墨烯自发热地板及制造方法及低电压自发热地板*** 技术领域
本发明属于建筑装饰材料领域，特别涉及石墨烯自发热地板及制造方法及低电压自发热地板***。
 背景技术
在寒冷的冬季，室内通常会利用暖炉、暖气等设备来为居家营造温暖的环境。但暖炉、暖气在运作时，经常有使用者不慎被烫伤的报道出现，而且极易导致居住者意外滑到触碰受伤，往往存在安全隐患。另外，暖炉、暖气占用室内空间，缩小了住房有效使用面积；同时，屋内受热不均，暖炉、暖气周围气温偏高，而远离暖炉、暖气的地方气温偏低，居住者体感不舒适。近年来，随着地暖设备的研究愈发成熟，发热地板逐渐成为居家取暖的首选。
市面上存在较多的发热地板，是将电热膜置于地板下方或地板中进行发热。这中间最大的问题是，没有专业知识的消费者，关心的是装饰效果和装修成本，容易安装一些并不适合地热条件的地板，从而导致以下一些问题。如：实木热传导性差，升温慢；多层实木甲醛、苯、氨等有害物质含量高，特别是在40℃温度下的甲醛释放量较大，产生家居污染，严重危害人们的身体健康。
现有发热地板主要是利用碳晶发热，以碳纤维为导电填料，半衰期短，使用寿命不长。现有发热地板根据人体对室内温度的需求仅仅能实现全方位的温度控制和关停，不能针对特定人群、特定位置和特定需求实现发热地板的独立温控，能源浪费的同时无法有效满足现实的使用需求。
随着时代的进步以及环保理念的提升，传统家居建材已经不能满足当下消费者的装修需求，环保建材正受到越来越多人们的关注。

 本发明的最佳实施方式
下面结合附图和以下实施例对本发明作进一步详细说明。
实施例1
图1为一种石墨烯自发热地板的俯视图；图2为图1的纵向截面图。如图1、图2所示，一种石墨烯自发热地板，包括地板本体1，地板本体1从上至下依次包括紧密贴合的耐磨层2、表面装饰层3、上绝缘阻燃耐温防水层4、上基材板层5、下基材板层7、下绝缘阻燃耐温防水层8和保温层9。
下基材板层7上表面设有至少一个槽深小于下基材板层7厚度的凹槽10，凹槽10的两端贯通下基材板层7，如图3所示。凹槽10内铺设有石墨烯发热元件6，以及与石墨烯发热元件6紧密贴合的导电线路11，每条导电线路11的两端连接有插接件，每条导电线路11的插接件均连接一独立的控制单元。本实施例中，导电线路11为导电铜箔、导电铜浆或导电银浆中的任意一种。
本实施例中，石墨烯发热元件6包括多层微片，单层微片厚度为10-30μm，微片包括石墨烯粉末层与玻璃纤维板层。优选的，石墨烯粉末为经过YH-7改性后的导热型石墨烯粉末，其导热、辐射散热性能大幅提高，并具备良好的电传导性能。
该石墨烯发热元件6是由如下重量份的材料制备而成：
石墨烯粉末86份；玻璃纤维10.4份；纳米竹炭纤维粉8.2份；纳米氧化铝7.5份；丙烯酸树脂 2.7份。
本发明提供的石墨烯发热元件6，可有效改善传统发热地板的热传导性能。通过在石墨烯粉末中加入玻璃纤维、纳米竹炭纤维粉、纳米氧化铝和丙烯酸树脂，可显著提高石墨烯自身的热传导性能，热传导性能提高40%；大大延长石墨烯元件6的使用寿命，使用寿命增加37.6%；有效改善石墨烯元件6释放的远红外和负离子功能，更加环保、更加健康，远红外和负离子辐射功能提高21.8%。
若剔除玻璃纤维、纳米竹炭纤维粉、纳米氧化铝和丙烯酸树脂中任何一种材料，则改变后的石墨烯发热元件6与完整添加上述四种添加剂的石墨烯发热元件6相比，其热传导性能平均降低10.2%，使用寿命缩减13.4%，远红外和负离子辐射功能降低15.7%。
若将玻璃纤维换成植物纤维、将纳米竹炭纤维粉换成普通纤维粉、将丙烯酸树脂换成环氧树脂或者将纳米氧化铝换成二氧化锰，则改变后的石墨烯发热元件6与完整添加上述四种添加剂的石墨烯发热元件6相比，其热传导性能平均降低6.2%，使用寿命缩减11.3%，远红外和负离子辐射功能降低13.6%。由此得出，只有在石墨烯中同时加入玻璃纤维、纳米竹炭纤维粉、纳米氧化铝和丙烯酸树脂，才能显著提高石墨烯自发热地板的热传导性能、使用寿命和远红外和负离子辐射功能。
进一步优选的，如图5所示，插接件包括电源接头121和防水防电堵头122，电源接头121与插接件对应的控制单元电连接。进一步优选的，电源接头121为导线的外接连接插针，并在导线外皮套有硬质塑料的保护外壳，避免插针受损。导线尾线通过防水防电堵头122进行绝缘防水处理，确保通电前导线的安全可靠及通电中的家人的使用安全。
上基材板层5上表面设有若干盲孔13,盲孔13内嵌有磁石柱14，磁石柱14的高度小于等于盲孔13的深度，如图4所示。
一种石墨烯自发热地板的制造方法，该制造方法包括以下步骤：
（1）选料：选用密度要求在900-1000 kg/m3、外形尺寸为920毫米×140毫米×10毫米的高密度纤维板材作为基材板坯料；
（2）前处理：将坯料放入干燥室，在180℃的温度下进行6-8小时的高温干蒸处理；干蒸过程中，适时将常压蒸汽送入干燥室内，对坯料进行喷蒸、调湿处理；
（3）刨铣加工：a.将前处理的坯料进行刨铣加工，加工后基材板的外形尺寸为900毫米×122毫米×5毫米；
b.部分基材板上表面铣出用于放置石墨烯发热元件的凹槽，所述凹槽的槽深小于基材板厚度，所述凹槽的两端贯通基材板，企槽标准为表面平整光洁，此批基材板即为下基材板；
c.部分基材板上表面铣出若干盲孔，要求孔内干净无多余物，此批基材板即为上基材板；
（4）铺线：在加工处理后的下基材板的凹槽内铺设导线；
（5）制作石墨烯胶水溶液：将石墨烯粉末、玻璃纤维粉末与地板粘合胶水混合、搅拌，制成石墨烯胶水溶液，静置备用；
（6）固化成形：将步骤（5）中制成的石墨烯胶水溶液涂于下基材板的凹槽内，常温下固化形成；
（7）组装：在上基材板盲孔内安装高度小于等于所述盲孔深度的磁石柱，而后在上基材板上表面涂胶设上绝缘阻燃耐温防水层，上绝缘阻燃耐温防水层的厚度为2毫米；上绝缘阻燃耐温防水层上表面涂胶设表面装饰层，表面装饰层厚度为1毫米；表面装饰层上表面涂胶设耐磨层，耐磨层厚度为1毫米；上基材板下表面涂胶粘接安装有石墨烯发热元件和导线的下基材板；下基材板的下表面涂胶设下绝缘阻燃耐温防水层，下绝缘阻燃耐温防水层的厚度为2毫米；下绝缘阻燃耐温防水层下表面涂胶设保温层，保温层的厚度为2毫米；对组装后的板材进行冷压，冷压时间不少于12小时；
（8）砂光处理：将组装后的板材上砂光机进行砂光，使地板表面达到一定的光洁度；
（9）上漆处理：将砂光处理后的地板吸尘后，上无色底漆，并经紫外光烘干；
（10）检验包装：质检人员严格按照国家标准对地板的等级、色号检验，分等，最后密封包装塑封出厂。
开启电源，导电线路11通过电流，电流激发地板中间嵌入的石墨烯发热元件6，石墨烯发热元件6快速升温，电能转化成热能，从而使地板发热。由于石墨烯发热元件6内部碳原子受激发后运动充分，能够维持稳定的运动空间，使得该地板的发热率稳定，发热均匀。
石墨烯发热元件6同时会释放波长为6-14微米的远红外线，该波段的远红外线被称为“生命光波”。“生命光波”渗入体内之后，促进人体微血管扩张，加速血液循环，有利于清除血管囤积物及体内有害物质，将妨害新陈代谢的障碍清除，重新使组织复活，促进酵素生成，达到活化组织细胞、防止老化、强化免疫***的目的，对于血液循环和微循环障碍引起的多种疾病均具有改善和防治作用。
导电线路11的插接件连接一独立的控制单元，用户可以独立对地板的通电电流大小进行控制，进而对地板的发热量实现智能化独立调节。
由于上基材板层5内嵌有磁石柱14，形成有益于人体健康的微磁场，人在该磁场作用下，相应形成了人体自身的磁场。通过利用上述物理补磁疗法可以预防疾病，缓解病痛，起到保健功效。
实施例2
实施例2在实施例1的基础上，提供了一种更为优选的石墨烯自发热地板结构，具体的，该实施例2进一步限定了：

表面装饰层3为三聚氰胺装饰纸、PVC板、防火板、装饰木单板中的任意一种，板层表面经由机械加工、贴面装饰或涂饰三种方式处理后，增加了板面的立体感、特殊性能及美观性。
上绝缘阻燃耐温防水层4和下绝缘阻燃耐温防水层8均由以下重量份原料高温复合制备而成：聚四氟乙烯15份、酚醛环氧树脂8份、三氧化二锑1份、聚醚砜6份和氯丁橡胶7份。两层防水层的防水等级≥IP×7。
上基材板层5和下基材板层7均为无机板、碳金板、高密度纤维板、石塑板、实木板中的任意一种。
保温层9优选为憎水环保型XPE泡棉双层铝箔。本产品由多层阻隔层材料复合而成，各层材料有着很好的耐磨性和高强的抗撕裂性。保温层9具有阻燃憎水、反热保温、节能环保等优点。
石墨烯自发热地板由上述各层复合粘结而成，防霉防潮、防火阻燃。配合着石墨烯释放远红外线，结合磁石的磁疗特性，强身保健，有益家人健康。
实施例3
实施例3在实施例1的基础上，提供了一种更为优选的石墨烯自发热地板结构，具体的，该实施例3进一步限定了凹槽10的数量为2n个，其中，n为自然数，且2n个凹槽10的宽度总和小于下基材板层7的纵向宽度。石墨烯发热元件6通电激发后释放出大量热能，为了确保地板各处吸收热量的均匀，进一步优选的，凹槽10沿下基材板层7的横向方向中心轴对称分布。同样为了确保磁场的释放均匀，并控制磁场的磁力大小以适合人体需要，更进一步优选的，盲孔13的圆心与上基材板层5的横向方向中心轴重合，盲孔13的数量为2m个，其中，m为自然数，且2m个盲孔13的直径总和小于上基材板层5的横向长度。
根据本发明的另一方面，还提供了一种低电压自发热地板***，如图6所示。该***包括若干拼装在一起的上述石墨烯自发热地板，***还包括电源15、温度控制器16、总控制器17和空气开关18。优选的，电源15选用三线电源插座。
每块石墨烯自发热地板上任意一条导电线路11对应的控制单元均电连接至总控制器17上；总控制器17通过供电主线分别与电源15和温度控制器16电连接，温度控制器16、电源15、空气开关17通过供电支线相互电连接。
其中，供电主线和供电支线均选用铜芯线，各项指标必须符合国家标准。供电主线和供电支线的导线直径与发热面积参照如下对应关系执行：当发热面积小于20m2时，导线直径为2.5mm2；当发热面积大于等于20m2且小于40 m2时，导线直径为4mm2；当发热面积大于等于40m2且小于60 m2时，导线直径为6mm2；当发热面积大于等于60m2时，导线直径为10mm2。
本***的安装流程如下：
1、从墙角处开始逐片安装发热地板，并用锤子与木楦将地板轻轻敲紧，锁住地板端头。
2、地板铺设完成后，所有插接件的电源接头121的槽口处整洁干净；所有未使用的插接件的导线尾线应选用防水防电堵头122进行绝缘防水处理。
3、将每块石墨烯自发热地板上任意一条导电线路11对应的控制单元电连接至总控制器17上。同时，总控制器17通过供电主线分别与电源15和温度控制器16电连接，温度控制器16、电源15、空气开关17通过供电支线相互电连接。
使用时，每块地板均是智能集成的独立单元，操作者根据家庭的实际需求，通过总控制器17对每个地板上任意一条导电线路11对应的控制单元单独控制关停和温度调节，从而实现了室内温度的分区控制。
为实现智能温控效果，进一步优选的，本***可在电源接头121或总控制器17处设置弹性温控保护器。当地板温度超过40℃，会自动断开电流，停止供热，以免地板温度继续升高；当地板温度不足40℃时，保护器又会自动接通电流，开始供热，使地板表面在使用过程中恒温40℃。整个过程全部由智能控制器自动完成，无须人工操作，省心省力。
本发明不局限于上述最佳实施方式，任何人在本发明的启示下都可得出其他各种形式的产品，但不论在其形状或结构上作任何变化，凡是具有与本申请相同或相近似的技术方案，均落在本发明的保护范围之内。
