Hollow diaphragm glass and manufacturing method thereof

Abstract

The invention discloses single-glass hollow diaphragm glass. The single-glass hollow diaphragm glass comprises glass, a spacing frame, a diaphragm and an adhesive, the spacing frame is fixedly adhered to the periphery of the glass through the adhesive, a positioning strip or a positioning groove is arranged at the adhesion position of the periphery of the glass and the spacing frame, the adhesive at least contains one quick-drying adhesive, and the quick-drying adhesive ensures that the spacing frame does not displace in the next film stretching process; and the diaphragm is fixed to the spacing frame, a cavity is defined by the glass, the spacing frame and the diaphragm, and the diaphragm is instantly flattened and tightened in the mode that the diaphragm is directly heated through heat tightening equipment. The invention further discloses double-glass hollow diaphragm glass which is composed of one piece of single-glass hollow diaphragm glass and one piece of glass or composed of two pieces of single-glass hollow diaphragm glass. The invention further discloses a manufacturing method and device of the hollow diaphragm glass, and low-cost, large-batch, mechanical and continuous production of the hollow diaphragm glass can be achieved.

Description

technical field [0001] The invention belongs to the production field of hollow glass, and in particular relates to a single-glass hollow diaphragm glass, a double-glass hollow diaphragm glass and a manufacturing method thereof. Background technique [0002] The hot mirror insulating glass is composed of two layers of glass and a special hot mirror film. Compared with the three-glass two-cavity insulating glass of the same structure, its thermal insulation performance remains the same, but its weight is reduced by nearly 1 / 3 , so the advantages are obvious; but there are also obvious disadvantages, mainly because the heat-stretching process needs to be used after the two-layer glass is combined to stretch and tighten the hot-mirror film in the middle to achieve a good visual effect; but because heat-stretching requires It can only be implemented after the structural sealant of glass edge sealing is cured, and the hot mirror film is heated through the glass, so the hot stretch...

AI Technical Summary

Problems solved by technology

[0004] During the hot stretching process, the hot mirror film will generate a large shrinkage force and apply it to the spacer frame, and the spacer frame is generally bonded with butyl glue (butyl glue can meet the requirements of air tightness), because butyl glue does not cure, Therefore, the movement of the spacer frame under the action of external force cannot be restricted, and only the structural sealant can be relied on, and the structural sealant needs 7-10 days of curing to cure, and only after curing can it play a role in positioning the spacer frame, resulting in a hot stretch cycle Very long and cannot be used for continuous production

[0005] The hot-stretching process is to heat the hot-mirror film to make it shrink. It is very difficult to heat-stretch the glass and the structural sealant after curing; The characteristic of hot mirror hollow diaphragm glass is that it has good heat insulation performance, so it takes a long time to heat up; during the heating process, the air layer will be heated and expanded, and the glass will be heated and deformed, so it is required that the heating rate should not only be slow, but also uniform, so that the whole The hot-stretching process requires several hours of heating and constant temperature time, plus the time required for slow cooling, the hot-stretching process takes longer, which not only consumes high energy, but also cannot carry out continuous production
