Description

一种可调光式门窗玻璃
技术领域
本发明涉及门窗技术领域,特别是一种可调光式门窗玻璃。
背景技术
门窗通常包括玻璃,玻璃的四周设有副边框,副边框的外侧连接外框,外框与墙体内的附框连接。现有的门窗在建筑施工过程中,通常是先将附框安装在建筑物的门窗安装施工洞口内,在建筑物主体竣工后,再利用扣件等连接构件将门窗安装在附框内。人们对于门窗玻璃不仅仅是出于安全、美观、质量等方面的考虑,同时还对门窗玻璃的实用性、功能性、科学性也提出了更高要求,亟需一款能够通过玻璃内部的膜技术来智能调节玻璃的透光性和透明度。
目前常见的门窗玻璃,当光照过强时,会通过玻璃射入室内,室内居住人员会受到强光射入而导致不舒服,且辐射大,尤其时夏天的时候,很容易受到红外线和紫外线的辐射而不利于人体健康。另外,处于室内的人员还需要一定的隐私。如果设置窗帘,会大大提高成本,而且窗帘容易粘灰尘,不仅对人体的健康不利,而且要经常清洗,费时费力。因此,本发明亟需设计一款可调光式玻璃,来防止强光直射室内人员,也能保护室内人员的隐私。
发明内容
本发明的目的是克服现有技术的上述不足而提供一种透明度可调,防辐射,舒适性高的可调光式门窗玻璃。
本发明的技术方案是:一种可调光式门窗玻璃,所述门窗玻璃上设有调光部,所述调光部包括调光膜层,调光膜层的上表面由下至上依次设有防辐射层、反射层、胶层和基材层;调光膜层的下表面由上至下依次设有保护层和自粘层。
进一步,所述调光膜层包括液晶膜,液晶膜的上表面设有第一导电层,液晶膜的下表面设有第二导电层。
进一步,所述第一导电层的一端连接第一电极,第二导电层的一端连接有第二电极,第一电极通过导线连接电源的正极,第二电极通过导线连接电源的负极,所述导线上设有用于控制第一电极和第二电极通断电的开关。
进一步,所述防辐射层为阻隔红外线和紫外线的薄膜或涂料;或者防辐射层为阻隔紫外线的薄膜或涂料。
进一步,所述反射层为反射隔热涂料。
进一步,所述自粘层包括粘贴层和设于粘贴层外表面上的不干胶防护层。
进一步,所述保护层由防水层替代。
本发明的有益效果:一方面,当调光膜层处于透明度时,通过调光膜层与反射层、防辐射层相结合,就能彻底除去太阳光中的太阳辐射,使进入室内的阳光柔和,舒适性好;当调光膜层处于非透明度时,可直接阻止光线穿透薄膜,而且反射层、防辐射层也吸收了太阳辐射,不仅能够防止室内的人被阳光晒到,而且还能保护室内人的隐私。
附图说明
图1是本发明实施例1的结构示意图。
具体实施方式
以下将结合说明书附图和具体实施例对本发明做进一步详细说明。
实施例1
如图1所示:一种可调光式门窗玻璃,所述门窗玻璃上设有调光部,调光部包括调光膜层,调光膜层的上表面由下至上依次设有防辐射层6、反射层7、胶层8和基材层9;调光膜层的下表面由上至下依次设有保护层2和自粘层1。
其中,调光膜层包括液晶膜4,液晶膜4的上表面设有第一导电层5,液晶膜4的下表面设有第二导电层3。第一导电层5的一端连接第一电极,第二导电层3的一端连接有第二电极,第一电极通过导线连接电源的正极,第二电极通过导线连接电源的负极,所述导线上设有用于控制第一电极和第二电极通断电的开关。
本实施例的防辐射层6为阻隔红外线和紫外线的塑料薄膜。这种塑料薄膜既能阻隔红外线,又能阻隔紫外线,即经过反射层7反射后的太阳光已经被反射层7吸收掉大量的红外线,还有部分红外线和所有的紫外线在经过防辐射层6,就可以彻底去除红外线和紫外线,使射入室内的太阳光更加柔和、安全。
本实施例中,反射层7为反射隔热涂料,如果防辐射层6为阻隔红外线和紫外线的塑料薄膜,那么反射层可无需选择能够吸收100%红外线的材料,这样能够降低成本。例如,可选择吸收70%~80%左右的红外线的材料即可。本实施例的反射层为涂料,可直接涂覆于防辐射层的上表面。
本实施例的基材层9为离型膜。防辐射层6上涂覆有反射层7,再经胶层8连接基材层9。
本实施例的自粘层1包括粘贴层和设于粘贴层外表面上的不干胶防护层,当将薄膜贴到玻璃上时,将不干胶防护层撕下,使粘贴层粘在玻璃上即可。
本实施例的工作原理为:撕下不干胶防护层,将粘贴层平整的贴在门窗玻璃的内侧面,完成薄膜的贴合。然后将第一电极和第二电极经导线分别连接电源的正极和负极,然后按下开关,使得调光膜层处于通电状态,第一导电层5和第二导电层3之间形成电场,在电场作用下,液晶膜4中的液晶分子有序排列,使光线能够透过薄膜,这是薄膜便呈现透明状态,外面的人能够看到室内。但即使呈现透明状态,室外的太阳光也不会直射入室内,而是先经过反射层7反射,以吸收80%-100%的红外线,经反射层7反射后的太阳光再经防辐射层6,彻底吸收红外线以及紫外线,去除太阳光中的太阳辐射,使进入室内的阳光更加柔和,舒适性好,且有利于人体健康。反之,通过开关将电源断开,液晶膜4中的液晶分子无序排列,这时调光膜变成非透明状态,使光线无法穿透薄膜,从而达到调光目的。
可以说,一方面,当调光膜层处于透明度时,通过调光膜层与反射层、防辐射层相结合,就能彻底除去太阳光中的太阳辐射,使进入室内的阳光柔和,舒适性好;当调光膜层处于非透明度时,可直接阻止光线穿透薄膜,而且反射层、防辐射层也吸收了太阳辐射,不仅能够防止室内的人被阳光晒到,而且还能保护室内人的隐私。
实施例2
与实施例1的区别在于,防辐射层为为阻隔紫外线的薄膜,主要起到吸收紫外线的作用。反射层优选为氧化铟银溅射层,可到90%以上的红外线阻挡率。
实施例3
与实施例1的区别在于,保护层由防水层替代,即调光膜层的下表面由上至下依次设有保护层和自粘层,能够防止水珠进入其它层。
