Problems solved by technology

[0003] It has been reported that by modifying the thermoplastic elastomer used in the peelable blue glue, the peelable blue glue can be quickly cured at room temperature, but the process of preparing the modified thermoplastic elastomer is complicated, and a large amount of toluene, xylene, methyl ethyl ketone, etc. are used. An organic solvent with a pungent smell, which is harmful to the human body and the environment
There is also research on adding chloroprene rubber to the raw material of peelable blue glue and using environmentally friendly solvents to prepare a self-drying peelable blue glue, which can be sprayed on the surface of the protected article, but a crosslinking agent is added, which may Corrosion to other electronic components near the screen
At the same time, after the device processing is completed, the peelable blue glue needs to be peeled off, which is prone to fracture and is not easy to peel off

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to a peelable adhesive and a preparation method and application thereof. Background technique [0002] When processing and manufacturing the surface of printed circuit boards, touch screens or other devices, in order to avoid damage to the devices, the peelable blue glue is usually coated on the surface of the device for protection, and the peelable blue glue can be peeled off after the processing is completed. Traditional peelable blue glue is a heat-curing adhesive that needs to be cured at high temperature. If it is used to protect touch screens or other electronic components, it will inevitably have a certain impact on electronic components. For this reason, the development of peelable blue glue that does not require high temperature and can be cured at room temperature is of great significance to the application of peelable blue glue in electronic components.
