Problems solved by technology

[0004] 1. The sealant (usually silicone glue, polysulfide glue, etc.) has a long curing time. After the insulating glass and the frame are bonded and fixed, they need to be fixed with tooling. It can be basically fixed after 3-4 hours. Remove the tooling and wait for 24 hours. The above can be fully cured, and the production cycle is slow
[0005] 2. The sealant has a very strong odor. After it is installed

Embodiment 1

[0044] refer to figure 2 Shown is a structural cross-sectional view of a specific embodiment of the glass door according to the present invention. The glass door is a double-layer hollow glass door, including an outer glass 1, an inner glass 2, and a spacer bar 3. The outer glass 1 and the inner glass 2 are separated by a spacer 3 to form a hollow 4, the spacer 3 is made of PVC material, and the spacer 3 contains molecular sieve, which is used as a desiccant. The spacer 3 is located around the hollow 4, and the outer side of the spacer 3 is bonded between the outer glass 1 and the inner glass 2 by a sealant 5. The outer side of the sealant 5 is provided with a PU frame 6, and the PU frame 6 is simultaneously The surrounding edges of the inner glass 2 and the outer glass 1 are wrapped to form an all-encompassing structure. The cross section of the PU frame 6 is U-shaped. The PU frame 6 of this embodiment wraps around the hollow glass as a whole to form an integral frame. In t...

Embodiment 2

[0052] refer to image 3As shown, it is a structural cross-sectional view of another specific embodiment of the glass door according to the present invention. The glass door is a double-layer hollow glass door. The difference between this embodiment and Embodiment 1 is that the PU frame 7 only wraps around the edges of the inner glass 2. , the outer edge of the outer glass 1 is flush with the outer edge of the PU frame to form a half-wrapped structure, and the section of the PU frame 7 is L-shaped, such as image 3 shown. Others are the same as in Embodiment 1, and will not be repeated.

[0053] Of course, two pieces of inner glass 2 in the above-mentioned embodiment can also be used to form a three-layer hollow glass door, and the two pieces of inner glass are also separated by spacers to form a hollow space. The spacer bar 3 can also be made of aluminum or composite material. Composite materials usually use glass fiber and reinforced composite materials with a mass percen...

Abstract

The invention provides a glass door which comprises an outer glass sheet, an inner glass sheet and a spacing bar. The outer glass sheet is separated from the inner glass sheet through the spacing bar, and a hollow space is formed. The spacing bar is located on the periphery of the hollow space. The outer side of the spacing bar is located between the outer glass sheet and the inner glass sheet, and the outer glass sheet and the inner glass sheet are bonded through a sealant. A PU frame is arranged on the outer side of the sealant. The PU frame wraps the periphery of the inner glass sheet or wraps the periphery of the inner glass sheet and the periphery of the outer glass sheet at the same time. The invention further provides a manufacturing technique of the glass door and refrigeration equipment adopting the glass door. Integrated formation of a door body is achieved by combining the PU and the RIM technique, the hollow glass sheets are sealed into an integral module through the PU material, and the undesirable odor problem of a sealant of a hollow glass door is solved; meanwhile, condensation of a frame can be prevented; and by the adoption of the integral forming technique, a few hours of curing time of the hollow glass sheets and the frame is shortened, the product takt time is shortened, and the production quality is improved.

Description

technical field [0001] The invention belongs to the technical field of refrigeration equipment, and in particular relates to a glass door, a preparation process and refrigeration equipment. Background technique [0002] At present, the insulating glass door body used for refrigeration equipment is generally two-layer insulating glass or three-layer insulating glass bonded or plugged into the frame to form a door assembly. Taking two-layer insulating glass as an example, the structure can be found in figure 1 As shown: the hollow glass door body includes outer glass a and inner glass b, the outer glass a and the inner glass b are separated by a spacer c, and sealed with two layers of glue, the first sealant d is Butyl glue, the second sealant e is silicone glue, and then the door body frame f (extruded frame, injection frame or aluminum alloy frame) is plugged and assembled with insulating glass, and bonded with sealant g. Wherein the sealant g and the second sealant are of ...
