Cavity film with film stretching frames and cavity film hollow glass

Abstract

The invention discloses a cavity film with film stretching frames. The cavity film comprises a spacing frame, two diaphragms and two film stretching frames, the two diaphragms are respectively fixed on two sides of the spacing frame, and a cavity is formed among the diaphragms, the spacing frame and the diaphragms to form the cavity film; and the outer sides of the two diaphragms are respectively provided with one film stretching frame, the spacing frame and the film stretching frames are provided with convex-concave structures which are matched with each other, and when the film stretching frames and the spacing frame are pressed, the convex-concave structures are embedded with each other, so that the diaphragms can be stretched. The invention further discloses cavity film hollow glass. The cavity film hollow glass comprises the cavity film with the film stretching frames and two pieces of glass, the two pieces of glass are pasted on the two sides of the cavity film, and the space formed by the two pieces of glass and the outer side of the cavity film is fully coated with the structural adhesive. The invention further provides a manufacturing method of the cavity film and the cavity film hollow glass. The manufacturing method has the characteristics of being simple in process, convenient to manufacture, low in cost and large in productivity.

Description

Technical field [0001] The present invention belongs to the field of hollow glass, and more particularly to a cavity membrane and cavity membrane in cavity films and a cavity membrane in a cavity and a continuous production apparatus. Background technique [0002] With the development of green energy-saving buildings, it has been increasingly high-increasing the heat insulation performance of the glass used. It has gradually developed from the original single cavity in hollow glass or even in the three-cavity of four vagumes. The increase in the hollow cavity, the problem is that the thickness and weight of the glass increases, the cost of the framework and the hardware also increases, so the cost of the doors and windows is also increased; and the optical plastic film is used instead of double cavity or more The technology of intermediate glass in cavity has been gradually accepted by users and markets. Since the optical plastic film has the same optical properties as ultra-thin...

Problems solved by technology

However, due to the complexity of its processing technology, it is difficult to combine with glass, resulting in many problems such as low production efficiency and unstable quality.

[0004] The structural characteristics of the existing diaphragm insulating glass determine that its structure is too complex, the production process is cumbersome, and the production and processing are difficult

Therefore, since the industrial production of diaphragm insulating glass, the insertion of elastic elements, the fixing and tensioning of optical plastic films, and the packaging with two pieces of glass inside and outside have become technical bottlenecks restricting automatic continuous production.

[0005] At the same time, in order to ensure that the diaphragm has pre-tension and film surface flatness, the stability of the spacer frame, and the bonding strength and sealing requirements of the glass, the packaging width at the edge of the glass is too wide, which brings about the problem of "cold edge".
