Detailed Description

The invention will be further elucidated and described with reference to the following embodiments and drawings in which:

referring to fig. 1 and 2, a sealing tape includes a sheet-shaped substrate 10, two foam strips 20, a polyimide film 30, a thermal conductive adhesive 41, and a fixing adhesive 42.

The cross section of the foam strip 20 is in an L shape, two foam strips 20 are arranged on two sides of the same end face of the substrate body 10, the two foam strips 20 are distributed oppositely, and the vertical parts of the foam strips 20 are adjacent to each other, so that a groove structure is formed. The polyimide film 30 is embedded at both ends thereof in the horizontal portions of the two foam tapes 20, respectively, and is adhered to the base material body 10. In other words, the polyimide film 30 is accommodated in the groove, and both ends of the polyimide film are respectively embedded into the foam strips 20 for fixation. The heat conducting glue 41 is filled between the two vertical parts of the foam strips 20 and is adhered to one end of the polyimide film 30 far away from the substrate body 10. The fixing glue 42 is filled on the surface of the horizontal part of the foam strip 20 and is adhered with the vertical part of the foam strip 20. Glue 42 admittedly through both ends, can make sealed sticky tape attached on waiting to seal the object, heat-conducting glue 41 is in and waits to seal gap department this moment, produces high temperature in the gap, transmits fast to polyimide film 30 through heat-conducting glue 41 on, because the superstrong high temperature resistant nature of polyimide film 30, can guarantee sticky tape middle part non-deformable. The foam strips 20 at the two ends can also isolate the heat in the middle part, so as to avoid melting the solid glue 42 at high temperature; meanwhile, the foam strip 20 can effectively relieve external impact according to good damping effect of the foam strip. The sealing adhesive tape has no difference with the adhesive tape used in daily life, is stored in a curled form, and can be pulled and cut when in use.
