[0025] Reference Figure 1-4 As shown, the utility model provides a technical solution: a sticky anti-bulging Mylar sheet, comprising a Mylar sheet body 1, and a bottom paper 2 is glued to the lower surface of the Mylar sheet body 1.

[0026] The following is a detailed description of its overall specific settings and functions.

[0027] In this embodiment: a plurality of ventilation slots 5 are evenly provided on the lower surface of the Mylar sheet body 1. The cross section of the ventilation slots 5 is triangular, and the ventilation slots 5 are located between the base paper 2 and the Mylar sheet body 1. During the pasting process, since the longitudinal area of ​​the Mylar sheet body 1 is small, bulging and blistering are not easy to occur. Even if bulging and blistering occur, the staff can easily squeeze out the bulging and blistering from the side of the Mylar sheet body 1. A plurality of rows of tear seams 7 are evenly provided on the lower surface of the base paper 2. The base paper 2 will be torn along the tear seams 7. A plurality of connecting strips 8 are evenly fixedly connected to the lower surface of the base paper 2. The connecting strips 8 are located on the side of the tear seams 7. By providing the connecting strips 8, the stability of tearing the base paper 2 at the tear seam 7 is improved.

[0028] Specifically, a plurality of connecting pieces 4 are evenly and fixedly connected to the lower surface of the base paper 2. By pulling the connecting pieces 4, the base paper 2 can be easily torn off the Mylar sheet body 1. A folding groove 6 is provided on the upper surface of the Mylar sheet body 1. The corresponding folding groove 6 is provided to facilitate the bending of the Mylar sheet body 1 at the tear seam 7, thereby facilitating the pasting of the Mylar sheet body 1 after the base paper 2 is torn off. The upper surface of the Mylar sheet body 1 is coated with a heat-resistant coating 3, which is a polyimide coating. The heat-resistant coating 3 made of polyimide coating has good performance stability in a wide temperature range, such as excellent mechanical properties, chemical stability, aging resistance, radiation resistance, etc. Coating on the Mylar sheet body 1 improves the heat resistance of the Mylar sheet body 1 during use as much as possible, and extends the service life of the Mylar sheet body 1 as much as possible.

[0029] Working principle: when it is necessary to paste the Mylar sheet body 1, the bottom paper 2 can be easily torn off the Mylar sheet body 1 by pulling the connecting piece 4, and the bottom paper 2 will be torn along the tear seam 7. The staff can tear the bottom paper 2 on the lower surface of the Mylar sheet body 1 according to the pasting order. After tearing off a strip of bottom paper 2, the Mylar sheet body 1 at this position can be pasted. By setting the connecting strip 8, the stability of tearing the bottom paper 2 at the tear seam 7 is improved, and the phenomenon of the bottom paper 2 being skewed during the process of tearing off the bottom paper 2 is avoided, and the stability of tearing the strip-structured bottom paper 2 is improved. At this time, the Mylar sheet body 1 at the torn bottom paper 2 can be pasted. During the pasting process, since the longitudinal area of ​​the Mylar sheet body 1 is small, bulging and bubbling are not easy to occur. Even if bulging and bubbling occur, the staff can easily squeeze it out from the side of the Mylar sheet body 1. The bubbles are bulging, and by setting the ventilation slots 5, the staff can not only squeeze out the bubbles easily, but also set the corresponding folding slots 6, which facilitates the bending work of the Mylar sheet body 1 at the tear seam 7 position, and then facilitates the pasting work of the Mylar sheet body 1 after tearing the base paper 2 position. The heat-resistant coating 3 made of polyimide coating has good performance stability in a wide temperature range, such as excellent mechanical properties, chemical stability, aging resistance, radiation resistance, etc. It is coated on the Mylar sheet body 1 to improve the heat resistance of the Mylar sheet body 1 during use as much as possible, and prolong the service life of the Mylar sheet body 1 as much as possible. By setting the above structure, the multi-time pasting work of the Mylar sheet body 1 is facilitated, and the structure divided into small strips is pasted in sequence, which effectively avoids the phenomenon of bulging and bubbling during the pasting process, and improves the effect of pasting and using the Mylar sheet body 1 as much as possible.

For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.
