Description

一种防火智能调光玻璃
所属技术领域
本发明属于玻璃加工及制造技术领域，具体涉及一种防火智能调光玻璃。
背景技术
防火玻璃，在防火时的作用主要是控制火势的蔓延或隔烟，是一种措施型的防火材料。现有的防火玻璃，如公开号为CN203742393U的中国实用新型专利公开了《一种新型防火玻璃》，其包括两大小相同的防火玻璃原片，在两防火玻璃原片的同侧均匀镀上透明的耐高温热反射膜镀层，在两防火玻璃原片的边缘之间设置有方框形低熔点管，在低熔点管内装有发泡剂，两防火玻璃原片及低熔点管之间为中空；在两防火玻璃原片及低熔点管的外缘涂有防火胶层。上述技术方案提高了防火玻璃的耐火完整性和耐火隔热性要求，但防火玻璃在长时间的阳光辐射下，吸收了大量的热能，隔热效果差；并且在黑暗环境下，不能起到指引作用，其使用范围受到限制。公开号为CN104402248A的中国发明专利公开了《一种防火玻璃》，它是在普通防火玻璃层上复合上LED发光玻璃层、图片胶片层和Low-E低辐射节能玻璃层而形成一种多层复合的多功能复合玻璃，在防火的基础上，增加了玻璃的使用范围。
智能调光玻璃是两层玻璃之间夹着液晶膜，液晶膜两面覆盖PVB膜或EVA膜，经高温高压胶合成一体的夹层结构的光电玻璃产品。使用者通过控制电流的通断与否实现玻璃透明与不透明状态切换，起到保护隐私等特殊功能。由于智能调光玻璃的夹层结构特点，它同时具备安全玻璃的特点。将智能调光玻璃制成具有防火功能的防火智能调光玻璃，其用途将更加广泛。
发明内容
本发明的目的在于克服现有技术存在的不足，而提供一种结构组成合理，具有智能调光功能，隔热和耐火效果好的防火智能调光玻璃。
为解决上述技术问题，本发明采用技术方案如下：一种防火智能调光玻璃，它主要包括两层防火玻璃层，所述的两层防火玻璃层之间设有一层智能调光膜，在防火玻璃层和智能调光膜之间还有一层用以胶合作用的PVB膜胶片或EVA膜胶片。
作为优选：所述PVB膜胶片或EVA膜胶片的厚度为1.14～1.52mm；所述智能调光膜的厚度为1.0～1.2mm，开关电压为36～75伏特，关闭时的透光率是2.0～2.5%，打开时的透光率是67～72%；所述防火玻璃为铯钾防火玻璃，其厚度为5～10mm。
作为优选：所述PVB膜胶片或EVA膜胶片通过高温高压胶合在防火玻璃层和智能调光膜之间；形成一种在智能调光膜两面贴合上两片防火玻璃的、具有智能调光和防火功能的、复合的防火智能调光玻璃。
作为优选：所述的智能调光膜上设置有多种方便电路控制的控制开关；所述智能调光膜包括两层PET膜，在两层PEY导电膜之间是一层聚合物分散液晶膜，PET膜的内表面设有ITO导电层。
作为优选：所述智能调光膜的两片PET膜内表面的ITO导电层分别与两个电极焊接，两个电极分别引出导线以备与外电源连接。
与现有技术相比，本发明在两片防火玻璃内夹一层智能调光膜，提供一种安全的防火智能调光玻璃，膜的存在，使本发明成为安全玻璃，智能调光膜的存在，实现透明与不透明之间切换，外侧两片防火玻璃的存在，能满足防火要求；本发明主要用于通道防火使用，当然也可以用于其他建筑上，具有结构组成合理，具有智能调光功能，隔热和耐火效果好等特点。
