Description

Heat insulation hollow glass

Technical Field

The utility model relates to the technical field of glass, in particular to hollow glass.

Background

With the higher and higher requirements of people on the performance of building materials, the use of hollow glass is increased. Compared with common single-layer glass, the hollow glass has good sound insulation and heat preservation effects, so the hollow glass is often used for improving the energy-saving effect when designing large buildings.

The hollow glass generally comprises two or more pieces of glass, the two adjacent pieces of glass are separated by an aluminum alloy frame containing a drying agent, and the joint part of the aluminum alloy frame and the glass is bonded by high-airtightness adhesive such as butyl rubber. During bonding, butyl rubber is generally coated on the side edge of the aluminum alloy frame, then the aluminum alloy frame is adhered to one piece of glass in advance, finally the other side of the aluminum alloy frame is compounded with a second piece of glass to form a three-layer structure of glass-aluminum alloy frame-glass, and then the three-layer structure is sent to a hot press for hot-press bonding, so that stable bonding between the three layers can be realized. When the hollow glass is produced by the method, glue leakage sometimes occurs, namely glue leaks from a part where the aluminum alloy frame is attached to the glass to a hollow part, so that a finished hollow glass product is flawed.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems, the utility model provides the heat-insulating hollow glass capable of preventing glue leakage.

In order to achieve the purpose, the utility model adopts the following technical scheme:

the utility model provides a thermal-insulated cavity glass, includes at least two-layer printing opacity glass and sets up the interval frame between adjacent two-layer printing opacity glass, its characterized in that: the spacing frame is provided with two bonding surfaces facing the first side light-transmitting glass and the second side light-transmitting glass, an outer end surface facing the outer side of the hollow glass and an inner end surface facing the inner side of the hollow glass; the bonding surface is provided with a first sealing adhesive layer and is bonded and attached to the light-transmitting glass through the first sealing adhesive layer; the bonding surface is provided with a plurality of outer convex parts and inner concave parts which are arranged at intervals; the joint of the bonding surface and the inner end surface forms a sealing part protruding towards the side edge, and the protruding height of the sealing part is larger than that of the outer protruding part.

Furthermore, a sealing rubber groove is formed between the outer convex part close to the sealing part and the sealing part.

In the field of hollow glass, the leaking glue includes two cases, one is that butyl glue and the like which form the first sealing layer are pressed to overflow, the occurrence of the cases is relatively less, more, silicone glue and the like which are arranged at the outer side of the spacing frame penetrate inwards through the first sealing layer, and the silicone glue and the like flow to the inner side surface of the glass to form flaws, and part of the occurrence of the problems is that the first sealing layer is not firmly bonded to generate gaps. According to the utility model, the bonding surface of the spacing frame forms a similar wave-shaped structure through the inner concave part and the outer convex part, so that the contact area between the first sealing layer and the bonding surface is increased, the bonding property between the first sealing layer and the spacing frame is enhanced, and a larger relative pressure is formed between the outer convex part and the glass, so that the sealing effect of the first sealing layer is stronger under the action of the relative pressure, and a gap is not easy to generate. However, when the structure is adopted, the side edge of the spacing frame is of a non-flat structure, when the spacing frame and the transparent glass are subjected to hot pressing, the first sealing layer is extruded by the outward convex part, the first sealing layer may seep outwards or inwards after being extruded, the first sealing layer seeping outwards has no obvious influence on the product quality, and the first sealing layer seeping inwards may cause the area of the glass for transmitting light to be polluted, so that quality defects occur. Therefore, the sealing part protruding towards the side edge is arranged at the joint of the bonding surface and the inner end surface, the pressure between the sealing part and the transparent glass is greater than that of the outer convex part, a narrow opening which is difficult to pass is formed, and the pressed first sealing layer overflows towards the outer side more, so that the product quality is not influenced early. In the process of gluing the spacing frame, the sealing glue groove is required to be prevented from being filled with glue forming the first sealing glue layer, so that a buffer space is reserved in the sealing glue groove, when the first sealing layer is pressed, the glue flowing to the sealing part is firstly filled into the sealing glue groove, and therefore the probability of glue leakage from the sealing part to the inside of the hollow glass is reduced.

Furthermore, an elastic rubber piece is arranged on the bonding surface of the spacing frame and is arranged in the leakage-proof groove in a matching mode.

Further, the elastic rubber member protrudes outward from the sealing portion.

Further, the first sealing layer is formed on the outer side of the elastic rubber piece. The outer side here means that the first sealing layer is located away from the hollow glass cavity with respect to the elastic rubber member.

In order to further improve the sealing effect of the sealing part, an elastic rubber piece can be arranged in the sealing rubber groove, and when the hollow glass is subjected to hot pressing, the elastic rubber piece can be tightly attached to the glass to prevent the rubber liquid from permeating into the hollow glass. The elastic rubber member should be selected from a material that is less stiff, softer and able to withstand the high temperatures during hot pressing.

Furthermore, the depth of the groove bottom of the sealing rubber groove is larger than that of the inner concave part.

Further, at least one inner side surface of the light-transmitting glass is provided with a low-radiation coating. The low-emissivity coating can reduce the heat conducted by the glass in a radiation mode, can reduce the heat transferred from the outside to the inside in summer, and can reduce the heat transferred from the inside to the outside in winter. Glasses which are usually provided with a low-emissivity coating are also referred to as low-e glasses.

Furthermore, a drying air cavity is formed inside the spacing frame, and drying agent is filled in the drying air cavity

Furthermore, the outer end face is provided with a moisture absorption hole.

Furthermore, a gap is reserved between the outer end face of the spacing frame and the edge of the light-transmitting glass, and a second sealing adhesive layer is filled between the outer end face and the edge of the light-transmitting glass.

In summary, the following beneficial effects can be obtained by applying the utility model:

1. according to the utility model, the sealing effect of the first sealing adhesive layer is enhanced by arranging the outer convex part, and no gap is generated in the first sealing adhesive layer under the pressure of the outer convex part, so that the condition that the glue solution forming the second sealing adhesive layer leaks into the glass cavity is avoided.

2. The sealing part and the sealing rubber groove are arranged to avoid the situation that the first sealing rubber layer seeps into the glass cavity after being pressed by the convex part, and further avoid the situation of rubber leakage.

3. According to the utility model, the elastic rubber piece is arranged in the sealing rubber groove, and the elastic rubber piece is tightly attached to the glass by utilizing the characteristic that the elastic rubber piece can deform per se, so that the condition that the rubber liquid leaks into the cavity is further avoided.
