Description

Point-bonded sealed hollow diaphragm glass

Technical Field

The utility model relates to a production field of hollow glass, especially a point glues sealed-in diaphragm hollow glass.

Background

In order to further improve the heat insulation and sound insulation performance of the hollow glass, the applicant proposes a double-glass membrane hollow glass with application number 2020107254343, but in subsequent production practices, the membrane hollow glass has many defects as the existing common hollow glass, for example, during the use process, especially in a low-temperature cold environment, the phenomenon of fogging or condensation often occurs in the hollow layer of the hollow glass, the phenomenon of water storage seriously occurs, the heat insulation performance and the visual effect of the hollow glass are greatly influenced, the service life of the hollow glass is greatly shortened, and the occurrence of the phenomenon is closely related to the production and assembly process of the hollow glass and the technical maturity degree of workers. The main reasons for unstable quality of the existing hollow glass are that the production and assembly process is laggard, the mechanization and automation degree is low, and the quality is limited by the responsibility and the operation level of workers. Therefore, the improvement of the mechanization and automation degree of the production of the hollow glass is the key for improving the quality of the hollow glass.

The existing production process of hollow glass is simple, the process influencing the production mechanization and the automation degree lies in the placement of the spacing frame, although the existing automatic placement machine of the spacing frame has high cost and cannot be popularized and applied in a large range, the existing automatic placement machine of the spacing frame still adopts manual installation; the manual installation is adopted, so that the production efficiency is low, the product quality cannot be guaranteed, and particularly, for large-size products, the spacer frame is easy to deform and droop, so that the spacer frame of the large-size hollow glass is difficult to guarantee to be parallel to the edge of the glass, the attractiveness is influenced, the consistency of structural adhesive is also influenced, and the sealing performance and the mechanical strength of the hollow glass are further influenced. Therefore, the automatic placement of the spacing frame is realized by a simple and easy method, and the method is the key for improving the mechanization and automation degree of hollow glass production, the production efficiency and the product quality.

The edge sealing of the existing hollow glass generally adopts two sealing steps, the first step is that butyl rubber is generally adopted between a spacing frame and the glass, the butyl rubber belongs to non-setting adhesive, has better water vapor barrier capability and is a main factor for blocking water vapor from entering a hollow layer; however, the spacing frame is made of spacing strips and has at least one seam, and two sides of the seam are not sealed by butyl rubber, so that the sealing defect exists; the first sealing not only has a sealing gap, but also integrally connects the glass and the spacing frame together through the sealant, so that the heat insulation performance is poor; the second sealing is arranged between the outer side of the spacing frame and the two pieces of glass, generally, structural adhesives such as silicone adhesive, polysulfide adhesive and the like are adopted, the main function of the structural adhesives is to provide bonding strength, the sealing performance of the structural adhesives is poorer than that of butyl adhesive, and the more main defect is that the curing time is long, at least 24-48 hours of static curing time is needed, the hollow glass cannot move in the period, otherwise, the dislocation between the two pieces of glass is easily caused, the butyl adhesive sealing layer is damaged, and the mechanical property of the structural adhesives is also adversely affected. Therefore, the main defects of the edge sealing of the existing hollow glass include that firstly, the sealing performance of the butyl rubber is good but the hollow layer is not sealed in a totally-closed manner, the structural rubber can seal the hollow layer in a totally-closed manner but the sealing performance is poor, secondly, the curing time of the structural rubber is too long, the production efficiency is seriously influenced, the product quality is also adversely influenced, thirdly, the partition frame and the glass are bonded in a continuous manner, the heat insulation performance is poor, a cold bridge is easily formed, and the heat loss of the edge of the hollow glass is caused to be large, the hollow glass is easy to condense and the like.

The existing spacing frame of the hollow glass is added with a molecular sieve as a drying agent to absorb water vapor in the hollow layer and water vapor entering the hollow layer through the edge of the hollow glass, generally, the molecular sieve is filled after the spacing frame is made, the molecular sieve can always absorb water in the environment in the period from the filling of the molecular sieve to the lamination of the glass, and because the period is as long as ten minutes to dozens of minutes, the molecular sieve can absorb a large amount of water in the outside air in the environment with higher humidity, especially in the environment with high temperature and high humidity in summer, the service life of the hollow glass is greatly shortened, and the service life of the hollow glass is influenced.

The edges and corners of the existing hollow glass are exposed outside, and are easy to collide to generate gaps and microcracks in the carrying process, the glass belongs to a brittle material, and the breakage of common glass and the self-explosion of toughened glass are mostly caused by the microcracks, so the exposed edges and corners of the hollow glass are important factors for damaging the glass.

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.

The application takes the prior application (application No. 2020107254343) as the background technology, and innovates and reforms the edge sealing material, the edge sealing structure, the edge sealing process and the production line equipment of the hollow glass of the diaphragm, thereby having important significance for improving the production automation level of the hollow glass of the diaphragm, shortening the production period, improving the product performance, reducing the production cost, increasing the productivity and the yield and prolonging the service life of the hollow glass of the diaphragm.
