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.

Example Embodiment

[0013] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so that the protection scope of the present invention can be more clearly defined.
[0014] See figure 1 , The embodiment of the present invention includes:
[0015] A PI double-sided adhesive tape comprising: a base layer 1, a first adhesive layer 2 and a second adhesive layer 3 coated on both sides of the base layer 1, a first release layer 4 combined with the first adhesive layer 2, and a second adhesive layer The second release layer 5 combined with layer 3;
[0016] Among them, PI film (polyimide film) is used as the base material to form the base layer 1; the glue that forms the first glue layer 2 and the second glue layer 3 can choose two different types of glue for the different materials of the bonded objects. In this embodiment, the first adhesive layer 2 is formed of silica gel, and the second adhesive layer 3 is formed of acrylic. Other different types of adhesives can also be used, and the examples are not given here; the first release layer 4 and The second release layer 5 is made of an easy-to-peel isolation material, and a PET fluorine film is preferably used.
[0017] The PI double-sided tape of the present invention has a tensile strength of 10-25 N/cm, an elongation of about 3%, and a 180° peeling force of 5-8 N/cm.
[0018] The PI double-sided tape of the present invention can bond objects of two different materials, has the characteristics of high viscosity, easy peeling, convenient use, etc., and can be widely used in decoration, clothing, automobiles, electronics, post and other industries.
