Abstract

The invention relates to an easy-to-uncover polyimide elastic heat-conducting adhesive tape which comprises foam (1), a heat-conducting material (2), adhesive glue (3), a base material (4) and a release film (5). The release film (5) is divided into two parts in the middle of the surface of the adhesive glue (3), a part is used for pinching, and the pinched part is mutually pasted without being bound. The problem that a polyimide adhesive tape is difficult to uncover due to the fact that a material used for making the adhesive tape is soft and fragile is solved, and heat-conducting and elastic functions are added.

Description

technical field [0001] The invention belongs to the field of adhesive tapes, in particular to an easy-to-remove polyimide elastic heat-conducting adhesive tape. Background technique [0002] The current polyimide tape is basically a design in which the release film and the rubber surface of the product are completely attached together. When using it, it is necessary to gently lift the release film from the edge of the tape, and then stick it to the desired position. place of use. However, because some materials are particularly soft, it is difficult to remove after die-cutting, especially in the insulation or heat conduction of mobile phones and electronic products, because the area of ​​the glue used is small, which increases the difficulty of removal. The application promotion of polyimide adhesive tape is limited. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an easy-to-remove polyimide elastic heat-conduc...
