Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of self-adhesive tapes, in particular to a reinforced silicone rubber self-adhesive tape. Background Art
[0002] Silicone rubber self-adhesive tape is made of high temperature resistant and stackable adhesive inorganic silicone rubber. The tape is attached with an easy-to-peel protective layer and can be used at H-level high temperature of 250℃. It is especially suitable for being wrapped around the outermost layer of cable terminals and is resistant to electrical tracking.
[0003] Silicone rubber self-adhesive tape generally consists of an isolation film and a self-adhesive tape body. When in use, the self-adhesive tape is wound around items such as cables at a certain angle, and the self-adhesive tape parts overlap when wound, and the overlapping parts stick together. However, the existing self-adhesive tape is only made of a single self-adhesive silicone rubber, resulting in low structural strength, easy to be damaged or broken during use, and during use, due to the flat surface of the self-adhesive tape, the contact area of the overlapping part is small, the bonding is not strong enough, and the sealing of the overlapping part is poor. For this reason, we propose an enhanced silicone rubber self-adhesive tape. Utility Model Content

When in use, the first self-adhesive layer is bonded to the second self-adhesive layer;
[0007] The side surface of the first self-adhesive layer is symmetrically connected with convex strips, and the side surface of the second self-adhesive layer is symmetrically provided with grooves. When in use, the convex strips are moved into the corresponding grooves.

DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0022] Reference Figure 1-Figure 4A reinforced silicone rubber self-adhesive tape comprises a reel 1, a self-adhesive tape body 7 is wound on the reel 1, the self-adhesive tape body 7 comprises a base layer 10, a first anti-tension layer 9 and a second anti-tension layer 11 are connected to both sides of the base layer 10, the first anti-tension layer 9 and the second anti-tension layer 11 are both made of glass fiber material, the strength of the self-adhesive tape body 7 can be increased under the action of the first anti-tension layer 9 and the second anti-tension layer 11, and the self-adhesive tape body 7 is prevented from being damaged and broken during use;
[0023] like Figure 2 As shown, the first tensile layer 9 is connected to the first self-adhesive layer 8 on the side away from the base layer 10, and the second tensile layer 11 is connected to the second self-adhesive layer 12 on the side away from the base layer 10. When in use, the first self-adhesive layer 8 is bonded to the second self-adhesive layer 12. In actual use, the self-adhesive tape body 7 is wrapped around an object such as a cable. When wrapped, Figure 4 As shown, the self-adhesive tape body 7 will partially overlap, so that the first self-adhesive layer 8 and the second self-adhesive layer 12 can be bonded to each other to complete the winding;
[0024] like Figure 3 and Figure 4 As shown, the side of the first self-adhesive layer 8 is symmetrically connected with convex strips 2, and the side of the second self-adhesive layer 12 is symmetrically provided with grooves 4. When in use, the convex strips 2 are moved into the corresponding grooves 4. In actual use, when the self-adhesive tape body 7 is wound, the convex strips 2 on one side will move into the grooves 4 on the other side of the self-adhesive tape body 7. This can increase the contact area of the self-adhesive tape body 7 when winding, thereby improving the adhesion and sealing effect.
[0025] like Figure 3 As shown, the inner end face of each groove 4 is provided with a second bevel 13, one side of the second bevel 13 is aligned with the opening of the groove 4, and the side face of each convex strip 2 is provided with a first bevel 6 matching the second bevel 13, and the first bevel 6 is adhered to the second bevel 13. Under the action of the first bevel 6 and the second bevel 13, the overlapping part of the self-adhesive tape body 7 can be kept flat when it is wound, thereby improving the sealing performance.
[0026] It should be noted that the first self-adhesive layer 8, the second self-adhesive layer 12, the first inclined surface 6 and the second inclined surface 13 are all made of self-adhesive silicone rubber, so that when connected, the first self-adhesive layer 8 can only be bonded to the second self-adhesive layer 12, but cannot be bonded to other foreign objects.
[0027] Specifically, when the utility model is used, the staff wraps the self-adhesive tape body 7 around an object such as a pipe. Figure 4As shown, during winding, one side of the self-adhesive tape body 7 will overlap with the other side, causing the convex strip 2 to move into the corresponding groove 4, and during the winding process, the first self-adhesive layer 8 will connect with the second self-adhesive layer 12, and the two will adhere to each other to complete the winding of objects such as pipes.
[0028] Furthermore, Figure 1 As shown, an isolation film 5 is provided on one side of the second self-adhesive layer 12, and third inclined surfaces 14 are provided on both sides of the isolation film 5. The third inclined surface 14 matches the second inclined surface 13. The isolation film 5 can be used to isolate the first self-adhesive layer 8 and the second self-adhesive layer 12 on the self-adhesive tape body 7 when the self-adhesive tape body 7 is rolled up, so as to prevent the two from being bonded together and affecting subsequent use.
[0029] Furthermore, Figure 1 As shown, a plurality of tear grooves 3 are equidistantly provided on the side surfaces of the isolation film 5 and the third inclined surface 14, and the isolation film 5 can be easily torn off through the tear grooves 3. In this way, in actual use, the excess isolation film 5 can be torn off according to the position of the end of the self-adhesive tape body 7 to prevent the rolled-up parts of the self-adhesive tape body 7 from sticking together.
[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
