Description
Technical Field
The invention relates to the field of glass deep processing, in particular to hollow glass with flexible edges and a manufacturing method thereof.
Background
At present, the energy consumption of buildings accounts for more than 30% of the total social energy consumption, the energy consumption of doors and windows accounts for about 50% of the energy consumption of the buildings, and the improvement of the heat insulation performance of the doors and the windows is a main way for promoting the energy conservation of the buildings; the hollow glass is a building energy-saving product with good heat insulation and sound insulation performance, and the application of the hollow glass is very common at present. When the inner surface and the outer surface of the hollow glass have temperature difference in the using process, the heat transfer of the middle part and the edge part is different. At the edge of the hollow glass, the spacing strips are in close contact with the inner glass and the outer glass through the sealant, so the heat transfer mode of the hollow glass is mainly heat conduction, and the heat transfer performance of the spacing strips has great influence on the heat transfer of the edge; because the gas in the hollow glass hollow layer has poor heat-conducting property and good heat-insulating property, the edge of the hollow glass can easily form a cold bridge. Because of the existence of the cold bridge, the temperature of the peripheral part of the hollow glass used for the building external window is obviously reduced in cold seasons, so that the building energy consumption is increased, the phenomena of dewing and frosting are generated at the edge of the hollow glass, the hollow glass is not sanitary, the appearance is influenced, and the window frame, the windowsill and even the wall are damaged. In addition, the air pressure of the hollow layer of the hollow glass can change along with the change of the temperature of the external environment, for example, when the temperature rises in summer or daytime, the air in the hollow layer of the hollow glass is heated and expanded, and generates outward thrust to the glass, so that the central part of the glass is raised; when the temperature drops in winter or at night, the gas in the hollow layer of the hollow glass shrinks when cooled, and an inward suction force is generated on the glass, so that the central part of the glass is sunken; the edge of the hollow glass is firmly bonded by the sealant, the spacing strips and the structural adhesive, the generated stress cannot be released, the edge of the glass is cracked in a sealing way and generates gaps after a long time, external water vapor gradually enters the hollow layer from the gaps, after moisture adsorbed by the desiccant molecular sieve in the spacing strips is saturated, the humidity of the hollow layer is increased, the inner surface of the glass is fogged and returns alkali, becomes black, white and opaque, the appearance and the visual effect are influenced, the heat preservation and heat insulation performance are influenced, the glass can be cracked in extreme weather, and the service life of the hollow glass is greatly shortened.
The service life of the existing hollow glass marked in the national standard is only 15 years, the service life of a building is as long as 70 years, and the used hollow glass needs to be replaced for many times in the life cycle of the building, so that not only is a large amount of waste of manpower, material resources and financial resources caused, but also a lot of unnecessary troubles are brought to a user. The service life of the hollow glass is only related to the glass and the edge sealing structure, the glass is made of inorganic materials, has very stable performance and can have the same service life as a building, and therefore, the service life of the hollow glass is determined by the reliability and the durability of the edge sealing of the hollow glass. Therefore, the key to save energy and reduce consumption in the building field is to prolong the service life of the hollow glass, especially to improve the edge sealing quality and performance of the hollow glass.
Disclosure of Invention
In order to solve the technical problems, the invention provides the flexible edge hollow glass which can adapt to the breathing phenomenon of the hollow glass, does not generate stress at the edge sealing part, prevents the sealing part from cracking and generating gaps, and greatly prolongs the service life of the hollow glass.
The purpose of the invention is realized by the following technical scheme:
a flexible edge hollow glass comprises glass, a hinge type spacing strip, a molecular sieve, bonding seal between the glass and the hinge type spacing strip and bonding seal at the periphery of the glass, and is characterized in that the glass has two pieces, and the length and the width of the glass are equal; the parts of the hinge type spacing strip are assembled together in advance, the segments are directly bonded to the periphery of the first glass bonding surface to form a closed frame, or the hinge type spacing strip forms a spacing frame and then is bonded to the periphery of the first glass bonding surface, and the second glass is bonded to the other surface of the hinge type spacing strip to align the peripheries of the two pieces of glass; or each part of the hinge type spacing strip is firstly segmented and directly bonded to the periphery of the bonding surfaces of the two pieces of glass respectively to form a closed frame, or each part of the hinge type spacing strip is firstly formed into a spacing frame and then is bonded to the periphery of the bonding surfaces of the two pieces of glass respectively, and the two pieces of glass are connected together through the parts of the hinge type spacing strip; the glass and the hinge type spacing strips are bonded together through a sealant or a structural adhesive or a double-sided adhesive tape, and a closed hollow layer is formed between the two pieces of glass and the hinge type spacing strips; at least one of the parts of the hinge type spacing bar is a cavity bar, and the molecular sieve is poured into the cavity of the hinge type spacing bar; one or more of a sealant, a structural adhesive, a sealing tape and a sealing adhesive tape is/are adopted to carry out integral sealing on the outer side edges of the two pieces of glass and the hinge type spacing strip, and the hollow glass after edge sealing can be directly transported and used without maintenance and solidification.
