Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, and more particularly to a hollow glass. Background Art

[0002] Insulating glass is a new type of building material that has good heat insulation, sound insulation, is beautiful and practical, and can reduce the weight of buildings.

[0003] Insulating glass is a high-performance sound-insulating and heat-insulating glass made by bonding two (or three) pieces of glass with aluminum spacers containing desiccant using a high-strength and high-airtightness composite adhesive. The aluminum spacers contain a desiccant that continuously absorbs moisture entering the spacing layer during the life of the insulating glass. The sealing strip formed by the solidification of the high-strength and high-airtightness composite adhesive firmly bonds the aluminum spacers and the two adjacent layers of glass.

[0004] For sealing performance considerations, when sealing insulating glass, the amount of adhesive used must be sufficient to allow sufficient contact area between the sealant formed by its solidification and the two layers of glass. Accordingly, the thickness of the sealant will be thicker, forming a large black edge, which will lead to a decrease in the proportion of the light-transmitting area of ​​the insulating glass.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0006] In view of the deficiencies in the prior art, the present invention aims to provide a hollow glass.

[0007] The above technical purpose of the present utility model is achieved through the following technical scheme: a hollow glass, including two single-layer glasses and an aluminum spacer located between the single-layer glasses, the edge of the single-layer glasses facing the aluminum spacer is provided with a frosted glass edge, and the aluminum spacer and the frosted glass edge are fixed by a sealant layer formed by the solidification of sealant.

[0008] The utility model is further configured as follows: a plurality of extruded strips are provided between the two single-layer glass panels, the two sides of the extruded strips are fixedly connected with side edges extending back to the aluminum spacer strips, the extruded strips are arranged parallel to the aluminum spacer strips, and the extruded strips, side edges and sealants are fixed.

[0009] The utility model is further configured as follows: the cross section of the aluminum spacer facing away from the center of the single-layer glass is configured in an inverted isosceles trapezoidal shape.

[0010] The utility model is further configured as follows: a plurality of micro-concave holes are provided on the surface of the aluminum spacer facing away from the center of the single-layer glass.

[0011] The utility model is further configured as follows: the single-layer glass is high-silica glass.

[0012] The utility model is further configured as follows: the sealant layer is made of hot-melt butyl glue.

[0013] In summary, the present invention has the following beneficial effects: by arranging a frosted glass edge on the edge of one side of the single-layer glass, the uneven surface of the frosted glass edge is utilized to increase the contact area between the single-layer glass and the sealant layer, that is, per unit area, the frosted glass edge and the sealant are in more complete contact than those of the smooth glass, and the sealant layer formed after the sealant solidifies has better sealing performance. Therefore, under the premise of the same sealing performance, the thickness of the sealant layer required by the present invention is smaller, the amount of sealant used is less, no large black edge is formed, and the light transmittance area of ​​the insulating glass is slightly increased.

[0018] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. Example

[0019] A hollow glass, such as Figure 1 As shown, it includes two single-layer glass 1 and an aluminum spacer 2 located between the single-layer glass 1. The aluminum spacer 2 contains a desiccant for continuously absorbing moisture that enters the spacer layer during the service life of the insulating glass to ensure the sound insulation and heat insulation performance of the insulating glass. The single-layer glass 1 is high-silica glass. The main component of high-silica glass is about 95% to 98% SiO2. Due to its high silicon content, it has high heat resistance and chemical stability, which makes the insulating glass perform well in high temperature environments and is suitable for various applications requiring high heat resistance and chemical stability.

[0020] like Figure 1 and Figure 2As shown, a frosted glass edge 3 is provided on the edge of the single-layer glass 1 facing the aluminum spacer 2, and the aluminum spacer 2 and the frosted glass edge 3 are fixed by a sealant layer 4 formed by solidification of the sealant. By providing the frosted glass edge 3 on the edge of one side of the single-layer glass 1, the uneven surface of the frosted glass edge 3 is utilized to increase the contact area between the single-layer glass 1 and the sealant layer 4, that is, per unit area, the frosted glass edge 3 is in more complete contact with the sealant than that of the smooth glass, and the sealant layer 4 formed after the sealant solidifies has better sealing performance. Therefore, under the premise of the same sealing performance, the thickness of the sealant layer 4 required by the utility model is smaller, the amount of sealant used is less, no large black edge is formed, and the light transmission area of ​​the insulating glass is slightly increased.

[0021] like Figure 1 As shown, the sealant layer 4 is made of hot-melt butyl adhesive. Hot-melt butyl adhesive has excellent resistance to ultraviolet aging. When exposed to sunlight for a long time, it can maintain its performance and is not easy to age or degrade, thereby increasing the service life of the insulating glass. In addition, hot-melt butyl adhesive has good bonding strength to the glass, ensuring its stability and reliability during use. Hot-melt butyl adhesive also has an extremely low water vapor permeability, which is very important for applications that require waterproofing and moisture-proofing. When used for sealing insulating glass, it can effectively prevent water vapor penetration and keep the interior dry.

[0022] like Figure 1 and Figure 3 As shown, the cross-section of the aluminum spacer 2 facing away from the center of the single-layer glass 1 is arranged in an inverted isosceles trapezoid, so that there is a larger contact area between the aluminum spacer 2 and the sealant layer 4, which can improve the sealing performance of the insulating glass. Furthermore, a plurality of micro-concave holes 7 are provided on the surface of the aluminum spacer 2 facing away from the center of the single-layer glass 1. The design of the micro-concave holes 7 further increases the contact area between the aluminum spacer 2 and the sealant layer 4, thereby improving the sealing performance of the sealant layer 4 and making the insulating glass have a longer service life.

[0023] like Figure 1 As shown, a plurality of extruded strips 5 are provided between the two single-layer glasses 1. Side edges 6 extending back to the aluminum spacer strip 2 are integrally formed on both sides of the extruded strips 5. The extruded strips 5 are arranged parallel to the aluminum spacer strip 2. The extruded strips 5, the side edges 6 and the sealant are fixed. After the sealant is injected between the two single-layer glasses 1, the extruded strips 5 are embedded between the two single-layer glasses 1 before the sealant solidifies. The extruded strips 5 squeeze the unsolidified sealant, so that the sealant is in more complete contact with the frosted glass edge 3 and the aluminum spacer strip 2. The sealant is squeezed between the side edges 6 and the frosted glass, so that a small amount of sealant can also be in full contact with the frosted glass edge 3, thereby improving the sealing performance of the sealant layer 4 formed after the sealant solidifies.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
