Description

Technical Field

[0001] This utility model relates to the technical field of hollow rubber strips, specifically a high and low temperature resistant hollow composite rubber strip. Background Technology

[0002] Insulating sealant strips are one of the key materials in the production of insulated glass, mainly serving a sealing and supporting function to ensure the heat insulation and sound insulation performance of the insulated glass. They are typically made of materials such as polyisobutylene, butyl rubber, and molecular sieves, and possess excellent airtightness and watertightness.

[0003] After installation, the hollow rubber strip is in direct contact with the external environment and is easily affected by the ambient temperature. In cold environments, the strip may harden or crack, while in high-temperature environments, it may soften or degrade and lose its sealing performance. Existing hollow rubber strips are made of a single material, have a simple structure, and poor resistance to high and low temperatures, making them prone to cracking or softening due to high and low temperatures, thus affecting the sealing effect. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high and low temperature resistant hollow composite rubber strip, comprising a sealing part and an outer edge part, and further comprising a connecting and insulating layer, wherein:

The surface of the connecting isolation layer is provided with multiple second microporous structures.

[0009] As a preferred embodiment of this utility model, the insulation layer is an irregularly shaped layer with a hollow interior, the width of the insulation layer is 2mm-3mm, and the insulation layer is made of fluororubber.

[0010] As a preferred embodiment of the present invention, the hollow portion of the insulation layer is filled with a filling layer, the filler of the filling layer is nano-silica, the outer edge is closed at the end, and the filling layer is fixed inside the insulation layer.

[0011] In a preferred embodiment of this invention, the second microporous structure connecting the isolation layer is respectively disposed on the upper and lower surfaces of the isolation layer, and the microporous structures of the second microporous structures connecting the upper and lower surfaces of the isolation layer are not interconnected.

[0012] As a preferred technical solution of this utility model, the sealing rubber sleeve is made of EPDM rubber, and the sealing rubber sleeve has multiple horizontally placed and equidistantly arranged support strips integrally formed inside, and the support strips are also made of EPDM rubber.

[0013] As a preferred technical solution of this utility model, the inner wall of the cavity inside the sealing rubber sleeve is provided with a plurality of first micropore structures, which are equidistantly arranged on the inner walls of the left and right sides and the upper and lower sides of the cavity.

[0014] As a preferred embodiment of this utility model, the pore size of the first microporous structure is 0.4mm-0.6mm, and the pore size of the second microporous structure is 0.8mm-1mm.

[0015] Compared with the prior art, this utility model provides a high and low temperature resistant hollow composite adhesive strip, which has the following beneficial effects:

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0025] Please see the appendix Figures 1-6 This utility model discloses a high and low temperature resistant hollow composite adhesive strip, including a sealing part 2 and an outer edge part 1, and also includes a connecting isolation layer 4, wherein:

[0026] The outer edge 1 has a multi-layer structure, including an outer insulating layer 11 made of silicone rubber and a heat insulation layer 13, with the heat insulation layer 13 wrapped inside the outer insulating layer 11;

[0027] The sealing part 2 includes a sealing rubber sleeve 21, and a cavity 3 is provided in the middle of the sealing rubber sleeve 21;

[0028] The connecting isolation layer 4 is located between the outer isolation layer 11 and the sealing rubber sleeve 21. The upper and lower ends of the connecting isolation layer 4 are fixed to the outer isolation layer 11 and the sealing rubber sleeve 21 respectively. The surface of the connecting isolation layer 4 is provided with multiple second micropore structures 41.

[0029] Please refer to the appendix. Figure 3 The insulation layer 13 is an irregularly shaped hollow layer with a width of 2mm-3mm and is made of fluororubber.

[0030] Specifically, the multi-layered structure can effectively isolate the transmission of high and low temperatures, and different composite materials can improve the durability of the rubber strip. Fluororubber has excellent high temperature resistance and can be used for a long time in the range of -20℃ to 200℃, making it particularly suitable for high temperature and chemically corrosive environments.

[0031] Furthermore, the hollow portion within the insulation layer 13 is filled with a filling layer 12, the filler of which is nano-silica, and the outer edge 1 is closed at the end, thus fixing the filling layer 12 within the insulation layer 13.

[0032] Specifically, adding nanofillers such as nano-silica to hollow rubber strips can significantly improve the material's resistance to high and low temperatures.

[0033] Please refer to the appendix. Figure 4 , Figure 5 The second microporous structure 41 connecting the isolation layer 4 is respectively disposed on the upper surface and the lower surface of the isolation layer 4. The microporous structures of the second microporous structure 41 connecting the upper and lower surfaces of the isolation layer 4 are not connected, and the pore diameter of the second microporous structure 41 is 1mm.

[0034] In this embodiment, the second microporous structure 41 can not only reduce weight, but also effectively adjust the heat conduction performance, so that the isolation effect of the connecting isolation layer 4 is better, so that the temperature transmitted by the outer edge 1 in contact with the outside is not entirely transmitted to the sealing part 2 that is not in contact with the outside, thereby reducing the impact of high and low temperatures on the sealing part 2, and thus improving the high and low temperature resistance of the sealing part 2. Example 2

[0035] Based on the above embodiment one, please refer to the appendix. Figure 6 The sealing rubber sleeve 21 is made of EPDM rubber. Inside the sealing rubber sleeve 21, there are multiple horizontally placed and equidistantly arranged support strips 22, which are also made of EPDM rubber.

[0036] Furthermore, the inner wall of the cavity 3 inside the sealing rubber sleeve 21 is provided with a plurality of first micropore structures 23, the pore diameter of the first micropore structure 23 is 0.6mm, and the first micropore structures 23 are equidistantly arranged on the inner walls of the left and right sides and the top and bottom sides of the cavity 3.

[0037] In this embodiment, the support strip 22 inside the sealing rubber sleeve 21 can improve the strength of the sealing rubber sleeve 21 and prevent the sealing rubber sleeve 21 from breaking due to excessive deformation under stress. In addition, the multiple first microporous structures 23 in the cavity 3 of the sealing rubber sleeve 21 can play a heat insulation role in high temperature environment, and can store heat in low temperature environment to prevent the material from becoming brittle due to sudden temperature drop. On the basis of isolating temperature with the connecting isolation layer 4, the high and low temperature resistance of the sealing rubber sleeve 21 is further improved.
