Description

Technical Field

[0001] The utility model relates to the technical field of adhesive tapes, in particular to an industrial heat-insulating adhesive tape. Background Art

[0002] Thermal insulation products are needed in heating equipment, high-temperature boilers, heat transfer pipes, high-temperature appliances in civilian kitchens, high-temperature steam pipes in commercial kitchens, or high-temperature components and accessories in equipment and instruments where high temperatures are generated. Thermal insulation products can effectively block the dissipation and emission of heat inside the heat source, reducing production energy consumption; at the same time, they can also reduce safety hazards caused by high temperatures, such as overheating and fire, and burns to the human body.

[0003] In the cooling equipment or cooling environment of industrial products, such as cold boxes and low-temperature containers, lower heat transfer is required to maintain the low temperature effect of the local environment in a relatively confined space. Insulation products can also be used to prevent external heat from penetrating into the internal low-temperature space, thereby achieving the effect of improving the cooling effect or extending the cooling time, reducing equipment energy consumption, etc.

[0004] At present, ordinary insulation products on the market are too thick and need to be reinforced with tape or double-sided tape. However, conventional tape and double-sided tape itself will melt and lose adhesion when placed on objects with a temperature exceeding 120 degrees, causing the insulation product to fall off. Therefore, external objects need to be used for bundling or clamp fixation, which does not meet the usage requirements. Summary of the Invention

[0005] The purpose of the present invention is to provide an industrial thermal insulation tape to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: an industrial thermal insulation tape, comprising a TPU protective layer, an aerogel insulation layer, a high-temperature resistant double-sided adhesive layer and a release paper, wherein an aerogel insulation layer is pressed under the high-temperature resistant double-sided adhesive layer, a TPU protective layer is hot-pressed under the aerogel insulation layer, and the release paper is affixed to the top of the high-temperature resistant double-sided adhesive layer.

[0007] Preferably, the thickness of the TPU protective layer is 0.03-0.08 mm.

[0008] Preferably, the aerogel thermal insulation layer is a structural layer with aerogel microparticles attached to the surface, and the thickness of the aerogel thermal insulation layer is 2-3 mm.

[0009] Preferably, the high temperature resistant double-sided adhesive layer is a high temperature resistant acrylic double-sided adhesive layer, and the thickness of the high temperature resistant double-sided adhesive layer is 0.03-0.1 mm.

[0010] Preferably, the high temperature resistant double-sided adhesive layer is a high temperature resistant silicone double-sided adhesive layer, and the thickness of the high temperature resistant double-sided adhesive layer is 0.03-0.1 mm.

[0011] Preferably, the thickness of the release paper is 0.1 mm.

[0012] Compared with the existing technology, the beneficial effects of the present invention are: the present invention has a simple structure and novel design, and the high-temperature resistant double-sided adhesive layer adopted can not only be directly attached to the surface of equipment or instruments with a temperature of 120-260 degrees; it can also be directly attached to cold-keeping equipment with a minimum temperature of -30 degrees; thereby greatly improving the convenience of construction.

[0013] The thickness of the aerogel insulation layer of the utility model is 2-3mm, which is not only ultra-thin but also has excellent thermal insulation effect. When a 200-degree heat source passes through the insulation tape, the temperature on the other side of the insulation tape is about 100 degrees. When directly attached to a cold-keeping device, it can effectively prevent external heat from penetrating into the internal low-temperature space. BRIEF DESCRIPTION OF THE DRAWINGS
