Hanging film hollow glass and manufacturing method thereof

Abstract

The invention discloses hanging film hollow glass and a manufacturing method thereof. The hanging film hollow glass comprises front glass, rear glass, spacing frames, hanging films and structural adhesive, the spacing frames are bonded to the corresponding positions of the peripheries of the front glass and the rear glass, one hanging film is hung between every two adjacent spacing frames, the lower end of each hanging film is fixedly connected with a bottom rod of which the length is matched with the width of each hanging film, and cavities are formed between the hanging films and the front and rear glass as well as between the hanging films; and spaces formed by the front glass, the rear glass and the outer sides of the spacing frames are fully coated with the structural adhesive, and after the structural adhesive is cured, the double-cavity or multi-cavity hanging film hollow glass is formed. The manufacturing method of the hanging film hollow glass has the characteristics of being simple in process, convenient to manufacture, low in cost and large in productivity.

Description

technical field [0001] The invention belongs to the field of hollow glass, and in particular relates to a hanging film hollow glass and a manufacturing method thereof. Background technique [0002] With the development of green and energy-saving buildings, the heat insulation performance of the glass used has been put forward higher and higher requirements, and it has gradually developed from the original single-cavity insulating glass to three-glass two-cavity or even four-glass three-cavity insulating glass. The increase of hollow cavities brings the problem that the thickness and weight of the glass are doubled, and the cost of frame materials and hardware also increases accordingly, so the cost of doors and windows also doubles; The technology of the intermediate glass of cavity hollow glass has been gradually accepted by users and the market. Since the optical plastic film has the same optical properties as ultra-thin glass, and has flexible characteristics that glass ...

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 suspended film insulating glass determine that its structure is too complicated, the production process is cumbersome, and the production and processing are difficult

Therefore, since the industrial production of hanging film insulating glass, the insertion of elastic elements, the fixing and tensioning of optical plastic films, and the packaging of the inner and outer glass have become the technical bottlenecks restricting automatic continuous production.

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