Two-sided differential adhesive tape and production method thereof

Abstract

The invention relates to a two-sided differential adhesive tape. The two-sided differential adhesive tape comprises a first release film, a first adhering layer, a polyester film, a second adhering layer and a second release film in turn from top to bottom, wherein a fluorine plastic release film is served as the first release film; the first release film is adhered to the first adhering layer; the polyester film is arranged between the first adhering layer and the second adhering layer; a single-silicon release film is served as the second release film; the second release film is adhered under the second adhering layer. According to the invention, the mixture of sodium bicarbonate particle and carbon powder is added, so that the radiating mode in the adhering layer can be effectively improved and the radiating effect can be obviously promoted. A novel two-sided differential adhesive tape with an excellent radiating function is supplied.

Description

technical field [0001] The invention relates to an adhesive tape, in particular to a double-sided differential adhesive tape and a production method thereof. Background technique [0002] In the electronics industry, adhesive tape is an indispensable material. Tape is required for the reposting, bonding, and fixing of any parts. Therefore, the demand for adhesive tape is very large and the quality requirements are also high. It occupies a mainstream position in the current market. Electronic products such as laptops, tablets, and smartphones continue to be thinner and smaller in design. There are many components in electronic products and various materials are involved. It is necessary to ensure that each component is firmly fixed without displacement or falling off. And it can withstand long-term use, and the fixed tape that matches it is facing a great test. The adhesive on both sides of the traditional double-sided tape is the same, and it may not be satisfactory for part...

[0002] In the electronics industry, adhesive tape is an indispensable material. Tape is required for the reposting, bonding, and fixing of any parts. Therefore, the demand for adhesive tape is very large and the quality requirements are also high. It occupies a mainstream position in the current market. Electronic products such as laptops, tablets, and smartphones continue to be thinner and smaller in design. There are many components in electronic products and various materials are involved. It is necessary to ensure that each component is firmly fixed without displacement or falling off. And it can withstand long-term use. The fixed tape that matches it is facing a great test. The adhesive on both sides of the traditional double-sided tape is the same. It may not be able to meet the needs of parts with two materials.

[0003] At the same time, the existing adhesive tapes are mainly used in electronic components. Electronic components are often in high-temperature working conditions. The tapes in the prior art often only play the role of sealing and fixing, not only can not conduct heat well, but also is not conducive to heat dissipation because of its heat insulation; therefore, how to improve the existing tapes to achieve ideal heat dissipation performance is a Technical problems that need to be solved urgently in this field
