Description

含有金属边的真空玻璃及其制备方法
技术领域
本发明涉及一种真空玻璃及其制备方法， 尤其是一种含有金属边的真 空玻璃及其制备方法。
背景技术
真空玻璃的概念最早出现在 1913年国外一项专利文献， 直到 20世 纪 80年代， 对它的研究才逐渐活跃， 2001年 7月， 西安交大邓宏飞等人 发表了研究实验成果，称采用 0.8mm特种玻璃做成 4x4mm2的支撑制作了 500x500mm2的平面真空玻璃， 并进行了太阳能集热实验， "集热性能比双 层玻璃优越， 集热温度比双层玻璃高 15〜30°C"; 北京新立基真空玻璃公 司称，在北京大学唐健亚教授 (曾在悉尼大学参与真空玻璃研究)的指导 下， 用金属做支撑， 可生产不同规格的平面真空玻璃， 其真空玻璃采用低 熔点玻璃粉融化将两片玻璃粘接， 属于刚性密封连接 。
无论哪种真空玻璃， 它们的周边密封一般都是采用无机材料， 如采用 低熔点玻璃粘合方式， 由于有机材料容易老化， 直接影响到真空玻璃的使 用寿命， 而采用低熔点玻璃粘合方式生产真空玻璃， 属于刚性密封玻璃， 可承受的双面温差一般为 60度， 最高不能超过 80度。 温差过高， 会导致 真空玻璃出现炸裂。 如何选择真空玻璃周边的密封材料， 一直是本领域长 期关注的热点。
此外， 在真空玻璃周边采用柔性材料或低熔点玻璃作为密封材料， 对 真空玻璃的周边都没有刚性保护， 尤其是钢化真空玻璃在搬运和安装的过 程中， 也容易使平面真空玻璃碰坏而炸裂。
发明内容
本发明的目的在于， 针对目前真空玻璃周边一般采用刚性密封， 采用 低熔点玻璃粉焊接， 组装和焊接技术要求过高， 产品的合格率较低， 目前 还不能实现钢化安全真空玻璃玻璃的大批量制造； 目前的真空刚性封边的 真空玻璃承受高温差的能力较低， 使用领域受限； 以及真空玻璃周边缺少 刚性材料的保护， 在搬运的过程中， 极易导致损坏等一系列问题， 提供一 种新的含有金属边的真空玻璃及其制备方法。 本发明的目的是这样实现的： 一种含有金属边的真空玻璃， 包括上下 两层平板， 两层平板之间设有等高的支撑体， 四周密封再抽真空后形成真 空密封腔， 其特征在于， 两层平板均为几何形状一致的玻璃平板， 或一层 为玻璃平板， 另一层为几何形状一致的金属平板； 沿玻璃平板周边是粘为 一体的金属带， 所述的金属带的厚度为 0.03~1.5mm， 金属带向外延伸， 超 越玻璃平板周围的边沿； 所述的四周密封是通过两层平板周边的金属带之 间， 或金属带与金属平板之间， 或它们与位于两层平板周边的型材截面为 矩形的金属框之间的密封焊接实现的。
在本发明中， 所述的真空腔中设置吸气剂。
在本发明中， 所述的真空腔中设有真空度检测单元的探头。
一种上述的含有金属边的真空玻璃的制备方法， 其特征在于， a) 将符合产品形状的玻璃平板周边通过低熔点玻璃与金属带密封粘 接， 或在玻璃平板周边镀上金属膜， 将金属带通过与金属膜焊接后形成密 封粘接；
b)将几何形状一致的玻璃平板之间均匀设置等高的支撑体，或玻璃平 板与几何形状一致的金属平板之间均匀设置等高的支撑体；
c) 沿两层平板边缘将对应边的金属材料焊接， 形成密封腔， 密封腔预 留有抽真空口， 通过抽真空口抽真空； 所述的金属材料是指： 金属带或金 属平板或截面为截面为矩形的金属框；
d)在抽真空后将抽真空口封闭， 形成含有金属边的真空玻璃。
在本发明的制备方法中， 所述的将两层平板对应边的金属材料焊接是 指： 将两层玻璃平板对应边的金属带延伸部分相向弯折相交后实施焊接； 或将与真空玻璃厚度一致的金属框夹持于上下层玻璃平板的金属带延伸 部分之间， 将金属带与金属框焊接； 或将玻璃平板的金属带延伸部分向几 何形状一致的金属平板弯折， 相交后与金属平板对应边焊接； 或将金属框 的一面与将玻璃平板的金属带延伸部分焊接， 另一面与金属平板焊接。
在本发明的制备方法中， 在将两层平板之间形成密封腔之前， 应该放 置吸气剂， 或置入真空度检测单元的探头， 或同时放置吸气剂和置入真空 度检测单元的探头。 在本发明的制备方法中， 加工金属框的型材截面为中空的矩形， 在中 空的矩形截面中， 面向真空密封腔的壁上设有气槽或气孔， 所述的吸气剂 和真空度检测单元的探头设在矩形的中空区域。
本发明的优点在于： 由于本发明周边密封采用的是金属焊接， 即不存 在柔性材料的老化问题， 又可以通过金属材料的变形吸收两玻璃平板由于 温差导致伸缩不一致而产生的应力， 防止平板真空玻璃受高温差炸裂； 由 于在真空玻璃周边有一圈金属， 可以减少搬运过程中的碰撞导致的损坏； 在真空玻璃的真空腔中设置吸气剂或真空度检测单元的探头， 可以确保密 封腔中的真空度， 并能对其进行检测， 提高真空玻璃的可靠性。

图 7以截面结构的方式公开了另一种玻璃平板 1与金属带 2密封粘接 的方法，它是首先在玻璃平板 1周边镀上一层金属膜 11，然后将金属膜 11 与金属带 2进行密封焊接 12， 使玻璃平板 1与金属带 2之间密封粘接的。
具体实施时， 图 7所示的金属膜 11可以镀为单层或多层， 在玻璃平 板 1周边镀上金属膜 11的方法可以采用磁控溅射、真空蒸镀、 喷镀、 电镀 等等工艺镀膜方式来实现。
