Preparation method of energy-saving heat mirror film insulating glass

Abstract

The invention relates to a preparation method of energy-saving heat mirror film insulating glass, which belongs to the field of glass processing technology, according to the preparation method, a professional laminating process can be developed, heat stretched process parameters are further adjusted, the process can be simply and easily operated, process parameters are easy to control, the phenomenon of film winkles and aluminum strip dislocation due to the fact that the laminated film is easy to be uneven when the heat mirror film is laminated can be solved, the extensibility of the heat mirror film is very good, and the appearance and performance are very good.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a method for preparing energy-saving hot mirror film insulating glass. Background technique [0002] With the rapid development of building curtain walls, the form of building curtain walls pays more and more attention to the effect of energy saving. Therefore, building curtain walls have higher and higher requirements on the performance of glass and various parameters. For architectural glass, lighting, viewing, and decoration are the basic requirements for glass, while energy saving and environmental protection are further requirements for glass, and are increasingly valued by the society. The existing market products are 1. Three-glass two-cavity insulating glass is composed of three pieces of glass. Its conventional glass composition structure is: glass A + spacer frame + glass B + spacer frame + glass C. Its characteristics include: [0003] (1) Different types of ...

AI Technical Summary

Problems solved by technology

[0008] (1) The weight of glass increases, resulting in increased pressure on door and window profiles and hardware;

[0009] (2) The sealing surface of the spacer is increased, resulting in an increase in the failure rate of the insulating glass

[0010] (3) The different pressures of the two cavities cause the glass in the middle to bear a large stress, which is easy to cause the glass to burst

[0014] Since the hot mirror film is a kind of soft polyester film, its hardness is equivalent to that of ordinary photographic negatives. In the process of assembling the film, it is easy to cause the film to fail to spread, and the edge of the hot mirror film is caused by the misalignment of the aluminum strip after hot stretching. Wrinkles and other phenomena make the appearance and performance of energy-saving hot mirror film insulating glass unsatisfactory
