Problems solved by technology

[0002] Existing commonly used double-sided tapes are mostly used for stationery affairs. Double-sided tapes are generally composed of a base material layer, an adhesive layer and a release paper layer. Extensibility, especially not easy to break and cut off, resulting in poor dimensional stability, and prone to low adhesion, easy to warp and other phenomena; and the current domestic tape industry is still at a low level in terms of technology, manufacturers Coat the adhesive on the base material layer, usually after it is fully dried and then arrange it into a roll. If the adhesive tape is too wet, the tape itself will stick together very tightly, it will be difficult to open when using, and some cannot be used at all, thus Disadvantages that lead to weak adhesive tape

Abstract

The invention relates to the technical field of adhesive tapes and in particular to a high viscosity environmental-friendly double-sided adhesive tape capable of being repeatedly used and a manufacturing method thereof. The high viscosity double-sided adhesive tape comprises a first release film, a low viscosity adhesive layer, a substrate layer, a high viscosity adhesive layer and a second release film which are successively arranged from bottom to top. The lower surface and the upper surface of the low viscosity adhesive layer are separately attached to the upper surface of the first release film and the lower surface of the substrate layer, and the lower surface and the upper surface of the high viscosity adhesive layer are separately attached to the upper surface of the substrate layer and the lower surface of the second release film. The environmental-friendly double-sided adhesive tape provided by the invention has a relatively high bonding force, is unlikely to upwarp, is good in weather resistance, easy to tear and convenient to use, and can be repeatedly used; the environmental-friendly double-sided adhesive tape also has the advantages of being good in light transmission, good in high-temperature resistance and etc, and has a high bonding force and peeling strength.
