[0002] Silicone rubber self-adhesive tape (also referred to as silicone tape) is made of high temperature resistant and stackable adhesive silicone rubber. The tape is attached with an easy-to-peel protective layer and can be used at H-level high temperature of 180°C. Silicone rubber self-adhesive tape has a wide range of uses, large usage, and excellent performance, especially in terms of anti-fouling, anti-hydrochloric acid, anti-ultraviolet, waterproof, oxygen-resistant, ozone-resistant, cold-resistant, heat-resistant, and high-pressure resistance. It is suitable for being wrapped in the outermost layer of cable terminals and other fields.
[0003] At present, when using silicone rubber self-adhesive tape to wrap and cover cables, the following undesirable phenomena are prone to occur: ① When the edge of the silicone rubber self-adhesive tape of the latter circle is wrapped around the edge of the silicone rubber self-adhesive tape of the previous circle, since the cross-section of the existing silicone rubber self-adhesive tape in the thickness direction (i.e., the vertical cross-section) is generally rectangular, this will cause the thickness of the parts of the silicone rubber self-adhesive tape that are wrapped and overlapped together to be greater than the thickness of the middle part of the silicone rubber self-adhesive tape, that is, a height difference is generated, which causes the silicone rubber self-adhesive tape and the cable to be prone to empty bag phenomenon, and the empty bag phenomenon will cause the insulation performance of the silicone rubber self-adhesive tape to the cable to deteriorate, and may even cause breakdown phenomenon, resulting in an increase in the risk factor of the surrounding environment. ② When the operator wraps the silicone rubber self-adhesive tape, the area of the edge of the silicone rubber self-adhesive tape of the latter circle that wraps and covers the edge of the silicone rubber self-adhesive tape of the previous circle is generally untraceable, and the operator mostly performs the wrapping operation based on work experience, which makes the wrapping operation effect of the silicone rubber self-adhesive tape uncontrollable and uneven, and cannot meet the work requirements of the high-voltage insulation standardization operation in the power industry.
[0004] In view of this, the present utility model is proposed. Summary of the invention

[0007] As a further improvement of the present invention, the cross-section of the self-adhesive tape body along its thickness direction is triangular or rhombus-shaped.
[0008] As a further improvement of the utility model, when the cross section of the self-adhesive tape body along its thickness direction is triangular, the bottom thickness of the cross section is the thickness of the two side edges of the self-adhesive tape body in the width direction, and is 20% to 40% of the thickness at the center of the cross section;
[0009] When the cross section of the self-adhesive tape body along its thickness direction is rhombus-shaped, the major axis thickness of the cross section is the thickness of the two side edges of the self-adhesive tape body in the width direction, and is 20% to 40% of the thickness at the center of the cross section.
[0010] As a further improvement of the present invention, the positioning piece is a discontinuous or continuous belt-like structure extending along the length direction of the self-adhesive tape body.
[0011] As a further improvement of the present invention, the color of the positioning piece is different from the color of the self-adhesive tape body, and the positioning piece can be exposed or penetrated from the self-adhesive tape body.

[0022] Combined with the attached drawings, the following description is given:
[0023] 1. Self-adhesive tape body; 2. Positioning piece. DETAILED DESCRIPTION
[0024] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.
[0025] Embodiment 1:
[0026] Please refer to the attached Figure 1 and attached Figure 2 As shown, this embodiment 1 provides a silicone rubber self-adhesive tape, including a strip-shaped self-adhesive tape body 1, wherein the self-adhesive tape body 1 is centered on the center line of its length direction, and the thickness gradually becomes thinner toward the edges on both sides of its width direction, and the thickness distribution of the self-adhesive tape body 1 is also symmetrically distributed along the center line of its length direction; in addition, the self-adhesive tape body 1 is also provided with a positioning piece 2 with a reminder function at the center along its length direction.
[0027] Compared with the prior art, the silicone rubber self-adhesive tape structure provided by the utility model has the following advantages: ① It is well known that when the silicone rubber self-adhesive tape is wrapped around a cable, one side edge (such as the left edge) of the silicone rubber self-adhesive tape of the latter circle will be wrapped around one side edge (such as the right edge) of the silicone rubber self-adhesive tape of the previous circle. The utility model, through structural innovation, designs the self-adhesive tape body of the silicone rubber self-adhesive tape into a "thick in the middle and thin on both sides" structure, which can greatly reduce the height difference (or thickness difference) between the parts of the self-adhesive tape body that are wrapped and overlapped together (that is, the right edge and the left edge that are wrapped and overlapped together) and the middle part of the self-adhesive tape body, thereby making it difficult for empty bags to occur between the silicone rubber self-adhesive tape and the cable, greatly improving the degree of fit between the silicone rubber self-adhesive tape and the cable, and effectively avoiding adverse phenomena such as gap discharge and damage of the silicone rubber self-adhesive tape, greatly improving the insulation effect of the silicone rubber self-adhesive tape on the cable, that is, greatly improving the protective effect of the silicone rubber self-adhesive tape. ② The utility model further provides a positioning piece with a reminder function at the center of the self-adhesive tape body along its length direction, so that the movement of one side edge of the latter circle of silicone rubber self-adhesive tape (specifically the self-adhesive tape body) when it is wrapped and overlapped on the previous circle of silicone rubber self-adhesive tape can be traced, that is, the positioning piece can be used as a position reference for the latter circle of silicone rubber self-adhesive tape to be wrapped and overlapped on the previous circle of silicone rubber self-adhesive tape, so that the effect and efficiency of the winding and covering operation of the silicone rubber self-adhesive tape can be controlled, thereby well meeting the work requirements of high-voltage insulation standardization operations in the power industry.
[0028] The structure of the silicone rubber self-adhesive tape described in Example 1 is described in further detail below.
[0029] Please continue to refer to the attached Figure 1 and attached Figure 2As shown, in this embodiment 1, the cross section of the self-adhesive tape body 1 along its thickness direction is triangular. It can be understood that the bottom thickness h of the triangular cross section is the thickness of the two side edges of the self-adhesive tape body 1 in the width direction, and according to the product coating performance requirements, especially to meet the use requirements of product surface flatness / consistent thickness during coating, the bottom thickness h of the triangular cross section and the thickness H at the center of the cross section satisfy the relationship: h = H*(20% to 40%). Furthermore, the bottom thickness h of the cross section is preferably 35% of the thickness H at the center of the cross section.
[0030] Please continue to refer to the attached Figure 1 and attached Figure 2 As shown, in this embodiment 1, the positioning member 2 is an intermittent or continuous strip structure extending along the length direction of the self-adhesive tape body 1, that is, the positioning member 2 is used as a "position reference line" when the silicone rubber self-adhesive tape is used for standardized coating operations. In addition, in order to realize that the positioning member 2 has a reminder function, this embodiment 1 also makes the following improvements and innovations to the positioning member 2:
[0031] Improvement 1: In this embodiment 1, the color of the positioning member 2 is different from the color of the self-adhesive tape body 1, and the positioning member 2 can be exposed or penetrated through the self-adhesive tape body 1, so that the positioning member 2 has a striking reminder function and better plays the role of a "position reference line".
[0032] Furthermore, when the positioning piece 2 is respectively exposed on both sides of the self-adhesive tape body 1 in the thickness direction (that is, the positioning piece 2 is partially built into the self-adhesive tape body 1 and partially exposed outside the self-adhesive tape body 1), the positioning piece 2 must be flush with the two sides of the self-adhesive tape body 1 in the thickness direction, so as to avoid the undesirable phenomenon that the height difference between the middle part of the self-adhesive tape body 1 and its width direction edge is increased due to the positioning piece 2 protruding from the self-adhesive tape body 1, thereby further ensuring the protective effect of the self-adhesive tape body 1.
[0033] When the positioning member 2 is not exposed on both sides of the self-adhesive tape body 1 in the thickness direction (i.e., the positioning member 2 is completely built into the self-adhesive tape body 1), the positioning member 2 must be visible from the self-adhesive tape body 1 to achieve a striking reminder function of the positioning member 2. Understandably, at this time, the self-adhesive tape body 1 can be preferably transparent, and the positioning member 2 can be preferably red, green, blue, yellow, black or other bright colors.
[0034] Improvement 2: In this embodiment 1, the positioning member 2 is made of a material with a fluorescent function or a thermochromic function, so as to enable the positioning member 2 to have a striking reminder function. Specifically, ① The fluorescent material can be an inorganic fluorescent material or an organic fluorescent material, wherein the inorganic fluorescent material includes a material compounded with alkaline earth metal sulfides (such as ZnS, CaS), aluminates (such as SrAl2O4, CaAl2O4), etc. as luminescent matrices and rare earth lanthanide elements (such as europium (Eu, erbium (Er, etc.) as activators. Organic fluorescent materials include organic small molecule luminescent materials (such as oxadiazoles and their derivatives, triazoles and their derivatives, rhodamine and their derivatives, etc.) and phosphorescent objects, etc. ② The material with thermochromic function can be thermochromic powder, thermochromic ink, or thermochromic paint, etc.
[0035] Furthermore, based on the above-mentioned improvement of the positioning member 2, the arrangement of the positioning member 2 relative to the self-adhesive tape body 1 may preferably be: the positioning member 2 is embedded in the self-adhesive tape body 1 and is respectively exposed on both sides of the self-adhesive tape body 1 in the thickness direction, and at the same time, the positioning member 2 is also flush with the two sides of the self-adhesive tape body 1 in the thickness direction.
[0036] Note: ① For the above two improvements of the positioning member 2, this embodiment can be configured with one or both during specific implementation, depending on product requirements. ② The positioning member 2 and the self-adhesive tape body 1 are integrally formed by an extrusion molding process, which is a conventional technical means in the field of polymer material processing, so it will not be described in detail here.
[0037] Embodiment 2:
[0038] The second embodiment also provides a silicone rubber self-adhesive tape, and compared with the first embodiment, the main difference of the second embodiment is that the cross-sectional shape of the self-adhesive tape body 1 in the second embodiment along its thickness direction is different from that in the first embodiment.
[0039] Please refer to the attached Figure 3 and attached Figure 4 As shown, in this embodiment 2, the cross section of the self-adhesive tape body 1 along its thickness direction is rhombus-shaped. It is understandable that the long axis thickness h of the rhombus-shaped cross section is the thickness of the two side edges of the self-adhesive tape body 1 in the width direction, and according to the product coating performance requirements, especially to meet the use requirements of product surface flatness / consistent thickness during coating, the long axis thickness h of the rhombus-shaped cross section and the thickness H at the center of the cross section satisfy the relationship: h = H*(20% to 40%). Furthermore, the long axis thickness h of the cross section is 35% of the thickness H at the center of the cross section.
[0040] Note: In addition to the above differences, other contents such as the structure of the positioning member 2 in the silicone rubber self-adhesive tape described in this embodiment 2, the molding method between the positioning member 2 and the self-adhesive tape body 1, etc. are the same as those in embodiment 1, so they are not repeated here.
[0041] To sum up, the structure of the silicone rubber self-adhesive tape of the utility model is simple, novel and reasonable. On the one hand, it can achieve a closer fit between the cable and the cable, greatly improving its insulation effect on the cable; on the other hand, it can make its own winding and covering operation traceable, which well meets the work requirements of high-voltage insulation standardization operations in the power industry.
[0042] In the above description, many specific details are described to facilitate a full understanding of the present invention. However, the above description is only a preferred embodiment of the present invention. The present invention can be implemented in many other ways different from those described herein, so the present invention is not limited by the specific implementation disclosed above. At the same time, any person familiar with the technical field can make many possible changes and modifications to the technical solution of the present invention by using the methods and technical contents disclosed above without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes. Any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the scope of protection of the technical solution of the present invention.
