Description

Technical Field

[0001] The utility model relates to the technical field of adhesive backing, in particular to a silicone foam structure of adhesive backing. Background Art

[0002] Adhesive is a sticky material that is often used to stick various materials together or fix them on the surface of an object. The adhesive is usually coated on a substrate so that the substrate can be easily pasted to other surfaces when needed and has good bonding properties. In general, adhesive is a very common and practical adhesive material that is widely used in various fields.

[0003] When the existing silicone foam structure with adhesive backing is used, the internal voids are larger due to the low density of the silicone foam, thereby slowing down the speed of heat conduction. The relatively low density limits the effective heat transfer of the silicone foam and affects its heat dissipation performance. For this reason, we propose a silicone foam structure with adhesive backing. Utility Model Content

[0004] The purpose of the utility model is to provide a silicone foam structure with adhesive backing to solve the problems raised in the above background technology.

[0008] A first waterproof layer is disposed at the upper end of the first sealing layer, a second waterproof layer is disposed at the lower end of the second sealing layer, and a second foam layer is disposed at the upper end of the first waterproof layer.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The silicone foam structure with adhesive backing is used in combination with a first foam layer, holes and grooves, and aluminum powder columns.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "several" is two or more, unless otherwise clearly and specifically defined.

[0024] like Figure 1-4 As shown, a technical solution provided by the utility model:

[0025] A silicone foam structure with adhesive backing, comprising a first foam layer 1, a first sealing layer 2 is arranged at the upper end of the first foam layer 1, a second sealing layer 3 is arranged at the lower end of the first foam layer 1, a plurality of holes 4 are opened inside the first foam layer 1, and the interiors of the plurality of holes 4 are filled with aluminum powder columns 5; a first waterproof layer 6 is arranged at the upper end of the first sealing layer 2, a second waterproof layer 7 is arranged at the lower end of the second sealing layer 3, and a second foam layer 8 is arranged at the upper end of the first waterproof layer 6; the aluminum powder columns 5 are made of aluminum borate;

[0026] In this embodiment, the filling of aluminum powder columns 5 can increase the thermal conductivity of the silicone foam. Aluminum is a good thermal conductive material that can transfer heat more effectively, thereby improving the heat dissipation effect of the backing glue. The setting of the hole grooves 4 can fix the aluminum powder columns 5 inside the foam to avoid movement or falling off during use. The setting of the hole grooves 4 can increase the surface area of ​​the foam, allowing it to better contact with the aluminum powder columns 5, thereby enhancing the heat transfer efficiency between the aluminum powder columns 5 and the foam. In addition, filling the aluminum powder columns 5 can also increase the structural stability and durability of the backing glue.

[0027] like Figure 2 As shown, an adhesive layer 9 is provided between the first waterproof layer 6 and the second foam layer 8, and the first waterproof layer 6 and the second waterproof layer 7 are made of fluoroplastic film; an adhesive layer 10 is provided on the lower end surface of the second waterproof layer 7, and the adhesive layer 10 and the adhesive layer 9 are made of amino adhesive;

[0028] In this embodiment, the first waterproof layer 6 and the second waterproof layer 7 are made of fluoroplastic film. The provision of the fluoroplastic film can effectively prevent water penetration and protect the material inside the adhesive from being affected by a humid environment.

[0029] like Figure 2 As shown, the first sealing layer 2 and the second sealing layer 3 are made of polyester film;

[0030] In this embodiment, the polyester film can effectively seal both sides of the hole groove 4 in the first foam layer 1 to prevent the aluminum powder filler from leaking out of the hole groove 4, thereby ensuring the overall performance of the material and preventing the loss of the filler or the entry of external impurities.

[0031] like Figure 2 As shown, the first foam layer 1 and the second foam layer 8 are made of silicone foam;

[0032] In this embodiment, the first foam layer 1 and the second foam layer 8 themselves have a certain sound insulation effect, and after being filled with the aluminum powder column 5, their sound insulation performance can be further improved, making the backing adhesive more effective in blocking sound propagation.

[0033] Working principle: The filling of aluminum powder column 5 can increase the thermal conductivity of silicone foam. Aluminum is a good thermal conductive material that can transfer heat more effectively, so it can improve the heat dissipation effect of the adhesive. The setting of the hole groove 4 can fix the aluminum powder column 5 inside the foam to avoid movement or falling off during use. The setting of the hole groove 4 can increase the surface area of ​​the foam, so that it can better contact with the aluminum powder column 5, thereby enhancing the heat transfer efficiency between the aluminum powder column 5 and the foam. In addition, filling the aluminum powder column 5 can also increase the structural stability and durability of the adhesive. The polyester film can effectively seal the two sides of the hole groove 4 in the first foam layer 1 to prevent the aluminum powder filler from leaking out of the hole groove 4, which can ensure the overall performance of the material and prevent the loss of filler or the entry of external impurities.

[0034] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
