As shown in fig. 1, the adhesive tape with a heat conducting function provided by the invention comprises a substrate layer 2, and an ester-philic coating 1 and a heat conducting adhesive layer 3 which are respectively coated on two surfaces (upper and lower surfaces) of the substrate layer 2, wherein the substrate layer 2 is made of plastic. In the adhesive tape of the present invention, the lipophilic coating layer is the outermost layer, that is, the coating layer which is in direct contact with the condensation tube when in use.

In the present invention, the lipophilic coating layer may be formed using a lipophilic material commonly used in the art, such as at least one of silicone oil, methacrylic acid, and methyl ethyl ketone, and preferably, the composition of the lipophilic coating layer includes silicone oil. That is, the lipophilic coating layer may be formed using a material whose main component is silicone oil. The density of the lipophilic coating may be from 0.9 to 1g/cm3。
In the present invention, the thickness of the lipophilic coating layer is preferably 0.05 to 0.1 mm. The use of an ester-philic coating is particularly advantageous for enhancing the adhesion between the foam and the tape.
In the present invention, the thermally conductive adhesive layer may be formed using a thermally conductive material commonly used in the art, such as at least one of butyl rubber, acrylic, and polyurethane. Preferably, the heat-conducting rubber layer comprises butyl rubber, namely, a material with the main component of butyl rubber can be used for forming the heat-conducting rubber layer, and the material with the main component of butyl rubber has no pungent odor and meets the requirement of food grade.
In the invention, the thickness of the heat-conducting adhesive layer is preferably 0.02-0.03 mm.
In the invention, the adhesive tape can also comprise release paper 4, and the position of the release paper enables the heat-conducting adhesive layer to be positioned between the release paper and the substrate layer. Preferably, the thickness of the release paper is 0.09-0.15 mm. Release papers from various sources in the art can be used to prepare the tapes of the present invention, for example, the release paper can be tan in appearance and can have a density of 90-110g/m3。
The thermal conductivity of the adhesive tape is in the range of 4-4.8W/MK, the tensile strength is in the range of 40-50N/cm, the elongation at break is in the range of 150-180%, the heat dissipation performance is good, and the adhesive tape is not easy to break.

Or forming an ester-philic coating and a heat-conducting adhesive layer on two surfaces of the substrate layer, and then pasting release paper on one surface of the heat-conducting adhesive layer. According to a more specific embodiment, the method of making the adhesive tape of the present invention comprises: coating the lipophilic coating on one surface of the substrate layer by using a roller, coating the heat-conducting adhesive layer on the other surface of the substrate layer by a rolling method, drying (for example, at 80-120 ℃ for 15-30min), and optionally pasting release paper.
When the refrigerator cooling tape is used, the refrigerator cooling tape can be directly attached to the condensation pipe, and as mentioned above, the refrigerator cooling tape can completely attach the condensation pipe and adhere foaming materials, so that the heat dissipation performance of the refrigerator can be effectively improved. Therefore, the outer surface of the condensation pipe provided by the invention is coated with the adhesive tape.
In addition, as mentioned above, the adhesive tape of the present invention is adhered to the outer surface of the condensation pipe of the refrigerator provided by the present invention.
