Description
Technical Field
The invention relates to the technical field of adhesive tapes, in particular to a traceable adhesive tape for a battery and a preparation method thereof.
Background
The adhesive tape can be divided into a high-temperature adhesive tape, a double-sided adhesive tape, an insulating adhesive tape, a special adhesive tape, a pressure-sensitive adhesive tape and a die-cutting adhesive tape according to the effects of the adhesive tape, and different effects are suitable for different industry requirements. The surface of the adhesive tape is coated with a layer of adhesive, so that the adhesive tape can stick to articles, the earliest adhesive is from animals and plants, and in the nineteenth century, rubber is the main component of the adhesive; while various polymers are widely used in modern times.
The existing traceable adhesive tape has poor chemical resistance, no corrosion resistance, no acid-base performance and low efficiency, for example, chinese patent document CN114196345A discloses a traceable adhesive tape which comprises a light-permeable base material and an adhesive layer which are mutually compounded; the light permeable substrate comprises a first surface and a second surface which are oppositely arranged; the first surface is a corona surface and a digital printing marker is arranged on the corona surface; the light-permeable base material is compounded with the adhesive layer through the first surface; the corrosion resistance of the adhesive tape in the document needs further improvement and optimization, and based on the corrosion resistance, the invention provides a traceable adhesive tape for a battery and a preparation method thereof.
