Abstract

The invention discloses a heat-conducting and flame-retardant double-sided adhesive tape that can be stretched and removed, and belongs to the application field of adhesive tapes. The double-sided adhesive tape comprises successively a release profile layer, a first pressure-sensitive adhesive layer, a substrate layer, a second pressure-sensitive adhesive layer, and a release profile layer; or sequentially comprises the first pressure-sensitive adhesive layer; the base material layer, the second pressure-sensitive adhesive layer A sensitive adhesive layer and a release profile layer; wherein, the substrate layer and the release profile layer are pasted through the first pressure-sensitive adhesive layer and the second pressure-sensitive adhesive layer respectively. The invention adopts a modified base material layer and adds flame-retardant and heat-conducting components to the adhesive, so that the adhesive tape can improve the flame-retardant and heat-conducting properties of the adhesive tape while ensuring the original adhesive force. When unbonding electronic devices or mobile phone batteries and other components, and removing the tape at 60-90°, the double-sided tape can also be easily pulled out without breaking between the pasted objects, providing convenience for later rework, maintenance and other processes , providing work efficiency.

Description

technical field [0001] The invention relates to a heat-conducting and flame-retardant double-sided adhesive tape that can be stretched and removed, and belongs to the application field of adhesive tapes. Background technique [0002] Existing stretchable and removable double-sided adhesive tapes use thermoplastic polyurethane film or rubber as the base material, and the glue adopts acrylic ester, rubber series, and polyurethane series. During the removal process, when the removal angle is greater than 60°, the It requires a significant increase in force and is easy to break. Electronic devices and mobile phone batteries have relatively small gaps. When removing the existing stretchable and removable double-sided adhesive tape, it is necessary to remove some other parts and then remove the adhesive tape. At the same time, the existing products are almost non-flammable, and some electronic devices, mobile phone batteries, etc. will generate a lot of heat, which cannot be expo...
