Problems solved by technology

[0004] In view of the above problems, the purpose of the present invention is to overcome the limited adjustable space and cumbersome preparation process of the easy-pull removable adhesive tape with substrate in the prior art, and the coating process of the existing non-substrate adhesive tape is also relatively cumbersome. , the lack of relatively low adhesion of the obtained easy-to-pull tape provides a non-substrate easy-to-pull tape with simple preparation process, low cost, convenient use, and high tensile strength, adhesive force, and tensile elongation. Removable tape, the non-backing tape is a double-sided fixed tape with high bonding strength. It can be used after peeling off the release paper or release film during use. When it needs to be removed, just pass through Stretch the tape, it can be removed, easy to use and simple, it can bring great convenience to the staff in the repair and maintenance of electronic components

Abstract

The invention discloses a non-substrate easy-to-pull removable adhesive tape. The adhesive tape has a thickness of 20 to 300 mu m, is prepared from the following components in parts by mass: 80 to 150parts of thermoplastic rubber, 60 to 150 parts of tackifying resin, 100 to 330 parts of toluene, 1 to 30 parts of softener, 1 to 10 parts of color paste, and 0.1 to 1 part of leveling agent. The non-substrate adhesive tape is a double-sided fixing tape with high bonding strength, can be used without pretreatment, and can be used after just peeling off the release paper or the release film. When the adhesive tape needs to be removed, the adhesive tape is only stretched to remove. The adhesive tape can bring great convenience to the staff during the maintenance of the electronic components.

Description

technical field [0001] The invention belongs to the field of double-sided adhesive fixing tapes, and in particular relates to a substrate-free, easy-to-pull, removable double-sided adhesive fixing tape. Background technique [0002] With the rapid development of modern technology, more and more electronic products appear in our life and play an irreplaceable role. As an indispensable item in the field of electronic products, adhesive tape is widely used in the bonding and fixing of screens, batteries and other components. However, many electronic components are difficult to disassemble after being fixed by tape. When the product needs to be reworked due to quality problems during the assembly process, temporary fixing is required during the product processing process, and the product needs to be disassembled for after-sales maintenance or recycling. To great inconvenience and cause certain economic loss. Therefore, in the process of using the adhesive tape, the adhesive pe...
