Description

Technical Field

[0001] This utility model relates to a wrapping tape, specifically a self-curing insulating armor wrapping tape. Background Technology

[0002] As is well known, according to electrical construction standards, exposed electrical connections in cables, optical cables, overhead bare wires, and lines must be covered with insulating tape. For example, when overhead bare wires are too close to buildings or trees, or when the electrical safety distance is insufficient, it is necessary to strengthen the waterproof sealing and insulation protection of the overhead lines; exposed metal parts of electrical connection points pose a risk of leakage and also require waterproof sealing and protection; the top of the support insulators of overhead lines in the field serve as an insulation layer to prevent birds from nesting and causing short circuits; exposed metal parts such as busbar connection points inside switchgear must be insulated and sealed, and the bottom cable inlet holes must be insulated and sealed.

[0003] In the prior art, the tapes used to achieve the above sealing structures are mostly made of ordinary insulating tape or insulating filler for covering or sealing. However, the existing tapes have poor plasticity and do not have puncture resistance and tensile strength. When covering products or filling insulation, their overall strength is insufficient and their toughness is poor. Furthermore, these insulating tapes do not have good fire resistance and water resistance; if a fire or water immersion occurs, they cannot maintain a relatively long-term safety.

[0004] Therefore, in view of the shortcomings of the existing technology, those skilled in the art urgently need to improve the insulation and puncture resistance of existing insulating coating products so that they can achieve coating and filling functions in fields such as power and water conservancy. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, this utility model proposes a self-curing insulating armor tape, which adopts a multi-layer structure, with an anti-puncture layer, a tension layer and a flexible adhesive layer inside the multi-layer structure, so that it can be gently bonded together during the wrapping process, thereby improving the overall wrapping strength.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A self-curing insulating armored packaging tape includes an inner armor layer bonded to an adhesive layer, wherein the adhesive layer is made of silicone rubber and the inner armor layer is made of mesh carbon fiber cloth or mesh glass fiber cloth; an isolation layer is provided below the adhesive layer, which is used as a product packaging spacer and needs to be removed when used to cover an object.

[0008] The adhesive layer is multi-layered, with an anti-stab layer inside. The anti-stab layer has a woven structure, which consists of a left diagonal weave and a right diagonal weave that intersect, with vertical woven layers interspersed between the left diagonal weave and the right diagonal weave.

[0009] The adhesive layer of a single self-curing insulating armor tape is larger than the area of ​​the inner armor layer. The purpose of this structure is to completely cover the inner armor layer when used for external wire harness wrapping.

[0010] The puncture-resistant interlayer of a single self-curing insulating armor tape has an area equal to or smaller than that of the adhesive layer. This structure can achieve overall strength compensation after the wire harness is wrapped.

[0011] This invention offers the following advantages: The inner armor layer is bonded to the adhesive layer, which is made of silicone rubber. This adhesive layer can be deformed through winding and kneading, making it suitable for various wire harness winding scenarios. It can also be kneaded into a ball-like structure for use as filler. The inner armor layer is made of mesh carbon fiber cloth or mesh glass fiber cloth, which isolates the wound object from the silicone rubber, protecting the internally wrapped wire harness. Below the adhesive layer is an isolation layer, used for product packaging separation and removed when used to wrap objects. This invention can also design the adhesive layer as multiple layers, with an anti-puncture layer within the inner interlayer to prevent punctures to the outer side of the wrapped wire harness. This invention offers diverse product specifications, is easy to operate, saves time and effort during installation, requires no heating or special tools, has high adaptability to substrates, and can be cut and shaped arbitrarily according to on-site application needs during construction.

[0018] The present invention will be further described below through embodiments. The following description is merely an exemplary explanation. Those skilled in the art can make further structural improvements based on the following explanation. The scope of protection of this patent shall be determined by the scope set forth in the claims.

[0019] Example 1:

[0020] A self-curing insulating armor tape, as shown in the attached image. Figure 1 As shown, it includes an inner armor layer 1, which is attached to an adhesive layer. In this invention, the inner armor layer 1 is made of mesh carbon fiber cloth or mesh glass fiber cloth. In this embodiment, considering the overall manufacturing cost, the inner armor layer 1 is made of mesh glass fiber cloth.

[0021] To improve the overall strength and stab-resistant effect of the self-curing insulating armor tape, this invention features a double-layered adhesive layer: an inner adhesive layer 2 and an outer adhesive layer 4. A stab-resistant interlayer 3 is positioned between the inner and outer adhesive layers 2 and 4. This stab-resistant interlayer 3 employs a mesh fiberglass cloth weave structure, with a left-side oblique weave 32 intersecting with a right-side oblique weave 31. This structure separates the inner and outer sides of the stab-resistant interlayer 3. To further enhance the density of the stab-resistant interlayer 3, a vertical weave layer 33 is interspersed between the left-side oblique weave 32 and the right-side oblique weave 31. Through this structural design, an additional stab-resistant interlayer 3 is added to the inner part of the adhesive layer 2, providing initial protection on the outside of the adhesive layer 2. Furthermore, when filled in a clump-like structure, it prevents the mesh fiberglass cloth from being exposed on the outside.

[0022] Both the inner adhesive layer 2 and the outer adhesive layer 4 are made of silicone rubber. This material is characterized by its resistance to hardening at low temperatures and its non-flowing nature at high temperatures, allowing for all-weather construction and its applicability in both northern and southern regions. The silicone rubber used in this product has innovative self-curing properties, curing at room temperature and reacting with trace amounts of moisture in the air. It exhibits excellent conformability, flexible construction methods, and can be used freely in confined spaces, easily accommodating irregularly shaped substrates. It also provides excellent adhesion when applied to irregularly shaped locations (such as wire clips). However, the aforementioned outer adhesive layer 4 is exposed. After the finished product is manufactured, it is transported and sold in rolls. To prevent it from warping and sticking together, an isolation layer 5 is attached below the adhesive layer. This isolation layer 5 is made of plastic and serves as a packaging divider. When this product is used to wrap an object, the isolation layer 5 needs to be removed.

[0023] Based on the above structural design, to improve the ease of use of this utility model, the self-curing insulating armor tape is made into segments, and then the segments of the self-curing insulating armor tape are rolled and packaged. However, when the inner armor layer 1 is applied to the outer adhesive layer 4, the inner armor layer 1 is designed in segments, and the area of ​​each segment of the outer adhesive layer 4 is larger than the area of ​​the inner armor layer 1. The purpose of this structural design is to completely cover the inner armor layer 1 when used for external wire harness wrapping, preventing the mesh fiberglass cloth from being exposed on the outside. The area of ​​the puncture-resistant interlayer 3 of a single piece of self-curing insulating armor tape is equal to or smaller than the area of ​​the adhesive layer. This structure can achieve overall strength compensation after the wire harness is wrapped, while preventing the reinforcing mesh fiberglass cloth from being exposed on the outside.

[0024] This utility model is particularly suitable for application to irregularly shaped parts such as connection clamps, outgoing clamps, and jumpers of overhead lines in power distribution networks. It can realize on-site rapid insulation and sealing, rapid emergency repair operations, and has a long safe operating life, which can meet the requirements of on-site construction and electrical performance of overhead line insulation.

[0025] This invention is widely used in the fields of insulation reinforcement, waterproof sealing, and outer casing repair in civil power, communication systems, and military equipment. It has good flame retardant properties, excellent flexibility, heat resistance, and fire resistance that meet the UL-V1 test level. During construction, it can be cut and shaped arbitrarily according to the needs of on-site application.
