The utility model discloses a vacuum glass, belonging to the technical field of glass products. On the two layer around the periphery of the glass seal, the central cavity vacuum zone, which is characterized in that the upper and lower two layers of glass were used to bump glass, flat glass, flat glass, convex glass sandwich around edges of the laminated glass sealing film fusion. The air side set around the interlayer film for laminated glass, PVB film or EVA film. A convex point is uniformly arranged on the surface of the convex glass, and the convex point and the main body glass are integrally molded or separately connected. The utility model directly by the convex glass and glass plate connected by the bump on the glass instead of the traditional vacuum glass in a separate set of intermediate support or intermediate, made of two layers of glass hollow region more stable support. Laminated glass film edge seals has the characteristics of heat resistance and cold resistance, high mechanical strength, strong coordination ability, - 40 DEG C to + 120 DEG C can keep various physical performance and stability.

技术介绍
目前,节约建筑能耗是我国当前的政策导向也是全球趋势。据统计,我国住宅能耗的40%是由门窗造成的,而建筑门窗的节能性能基本上决定于玻璃的 节能性能。真空玻璃的传热系数低、隔热隔声性能优良,在一些领域尤其是在 建筑门窗玻璃应用领域有庞大的需求,但有一些技术和工艺不利于工业化快速 生产。如专利号200420109208.9的中国专利公开的柔性支撑真空玻璃,中间 层采用支撑物,采用复合玻璃密封胶封口。其产品一般只能用于中空玻璃,玻 璃密封胶类产品使用在真空玻璃的封边结构上,透气率很难保证在10—8pa L/S 级别上。且由于其在玻璃面上采用抽气装置,其工艺性难以实现高速批量生产。 乂如专利号200510069186.7的中国专利公开的建筑真空玻璃板的生产方法, 特点是采用丝网印刷工艺印制围边封接带和中间支承点的焊接玻璃料,其不在 玻璃上使用抽气装置,在真空高温封接工序同时完成玻璃封接与真空腔的形成。 这种方法,要求真空室加热到200—40(TC,焊接工作温度达380—48(TC,极大 地耗用能源,也无法使 ...
【技术保护点】
真空玻璃,上下两层玻璃周边围接密封,中部空腔构成真空区,其特征在于上下两层玻璃分别采用凸点玻璃(1)、平板玻璃(2),凸点玻璃(1)、平板玻璃(2)夹层围边采用夹胶玻璃胶片(3)融合密封。
