Embodiment 1
[0030] see Figure 1-3 As shown, the present invention is a double-function freezer support leak-proof bubble seal, including a sealing plate body 1 and a coating layer 2,
[0031] One side of the sealing plate body 1 is provided with a coating layer 2;
[0032] Wherein, the sealing plate body 1 is divided into an opening part 2 and a sealing part 3, and the opening part 2 has a through hole matched with the installed condensing pipe or water pipe;
[0033] Wherein, coating layer 2 glue layer 5 and release paper 6, glue layer 5 is attached on the side of sealing plate body 1, and release paper 6 is attached on the outside of glue layer 5.
[0034] Further, the through hole formed on the hole portion 2 is located at the center of the area.
[0035] Further, the thickness of the sealing plate body 1 is 4-12mm.
[0036] Further, the sealing plate body 1 adopts one or more of PU, PE, EPDM or rubber-plastic viscosesponge.

Abstract
The invention discloses a difunctional freezer support bubble leakage prevention seal part, and relates to the technical field of freezer support seal. The seal part comprises a seal plate body and acoating layer, the coating layer is arranged on one side face of the seal plate body, the seal plate body is divided into a pore opening part and a seal part, the pore opening part is provided with athrough hole matched with a condensation pipeline or water pipe, the coating layer comprises a gluing layer and a released paper, the gluing layer is attached to the side face of the seal plate body,the released paper is attached to the outer side of the gluing layer, the pore opening part, and the sealing part are arranged on the seal plate body, seal work of different areas can be finished, andthe problems that a traditional leaking stoppage support leaks bubbles, whole scrapping is caused, the foaming cost is high, and energy losses are caused are effectively solved.
Description
technical field [0001] The invention belongs to the technical field of freezer support seals, in particular to a double-function freezer support leak-proof bubble seal and a preparation process thereof. Background technique [0002] In the freezer manufacturing industry, bracket leakage has always been an industry problem. In order to solve the above problems, various freezer manufacturing enterprises have invested a lot of manpower, material resources and financial resources in terms of structural design, optimization of plugging materials and professional cleaning equipment. However, stent leaking has not been effectively resolved. [0003] The reason is that the installation of the sewer pipe breaks through the sealing material and the difficulty in sealing the anti-condensation pipe out of the box is the two main reasons. The bracket leakage caused by these two reasons can lead to shrinkage and scrapping of the whole machine in serious cases. Secondly, after the bracket...
