Description

一种高隔热降噪防辐射真空玻璃及其制造方法
技术领域
本发明涉及一种高隔热降噪防辐射真空玻璃及其制造方法。
背景技术
真空玻璃是将两片平板玻璃四周密闭起来,将其间隙抽成真空并密封排气孔,两片玻璃之间的间隙为0.1-0.2mm,真空玻璃的两片一般至少有一片是低辐射玻璃,这样就将通过真空玻璃的传导、对流和辐射方式散失的热降到最低,其工作原理与玻璃保温瓶的保温隔热原理相同。真空玻璃是玻璃工艺与材料科学、真空技术、物理测量技术、工业自动化及建筑科学等,多种学科、多种技术、多种工艺协作配合的硕果。
真空玻璃是一种新型节能玻璃,它基于保温瓶原理,将两片玻璃四周密封,中间间隔为0.1-0.2mm的薄真空层。由于没有气体传热,内表面又有起保温瓶银膜作用的透明低辐射膜,使真空玻璃的保温隔热性能远优于目前已广泛使用的“中空”玻璃。
然而,目前市场上大多真空玻璃保温效果并不好,且如果长时间使用后,密封不严会严重影响其保温效果,且功能单一。
对此,目前国内主要存在如下专利文献:
如授权公告号:CN204782596U,公开了一种真空玻璃,具体为一种真空玻璃。其包括第一玻璃层(1),第二玻璃层(2)及第一玻璃层(1)与第二玻璃层(2)之间形成的抽真空腔体(3),且抽真空腔体(3)四周设有密封装置(4),一端与抽真空阀体(5)连接;所述的抽真空腔体(3)内部均匀的设有支撑物(6),其一端、第一玻璃层(1)与第二玻璃层(2)之间设有组成密封装置(4)的密封胶条(7),抽真空腔体(3)与密封装置(4)相对的另一端设置的抽真空阀体(5)包括玻璃安装孔(401),一侧设置的快速连接头(402),中心腔体内部安装的抽真空阀(403)。其有益效果在于:生产工艺简单、节省能源、隔音效果好,并且制造、使用成本低,使用广泛。虽然该真空玻璃具有一定的保温、降噪效果,然而,其并没有防辐射效果,且保温效果仅仅通过密封实现,并不明显。
发明内容
为解决上述存在的问题,本发明的目的在于提供一种高隔热降噪防辐射真空玻璃及其制造方法,所述玻璃兼具保温、防辐射及降噪三重功效,防辐射效果好,设计提供专门的隔热保温涂层,涂层成分搭配合理、生产方法易操作,导热系数低,保温效果好,且只需喷涂使用即可在玻璃表面形成涂层,使用简单,且涂覆后不易脱落,使用寿命长,PVB胶膜设置于真空内腔内,隔音吸音效果良好,经济成本低,使用前景好。
