Abstract

The invention discloses a PI (Prodium Iodide) double-sided adhesive tape, comprising a first release layer, a first adhesive layer made of a first adhesive material, a base layer, a second adhesive layer made of a second adhesive material and a second release layer, wherein the five layers are overlapped and composited together in sequence, the base layer is a PI film, and the first adhesive material and the second adhesive material are two different adhesive materials. According to the provided manner, the PI double-sided adhesive tape disclosed by the invention can be used for sticking two objects made of different materials, and has the advantages of high stickiness, easiness for peeling-off and convenience for use.

Description

technical field [0001] The invention relates to the field of adhesive tapes, in particular to a PI double-sided adhesive tape. Background technique [0002] Commonly used double-sided tapes are generally used as stationery supplies, or to replace ordinary adhesives to paste industrial accessories. PI film (polyimide film) has excellent high and low temperature resistance, electrical insulation, adhesion, radiation resistance, and medium resistance, and can be used for a long time in the temperature range of -269 ° C to 280 ° C It can reach a high temperature of 400°C. PI film is used as the base material in the adhesive tape, which can greatly improve the performance of the adhesive tape. [0003] Existing double-sided adhesive tape is mainly made by coating glue on both sides of the base material to form an adhesive layer, and then attaching an easy-to-peel isolation material outside the adhesive layer. The glue forming the viscose layer generally adopts the same materia...
