Description

Technical Field

[0001] The utility model relates to the technical field of adhesive tapes, in particular to a tensile-resistant insulating adhesive tape. Background Art

[0002] Insulating tape refers to the tape used by electricians to prevent leakage and play an insulating role. It is also called insulating tape, tape tape, which consists of a base tape and a pressure-sensitive adhesive layer. The base tape is generally made of cotton cloth, synthetic fiber fabric and plastic film, etc. The adhesive layer is made of rubber plus a compounding agent such as a tackifying resin, with good viscosity and excellent insulation performance.

[0003] For example, a Chinese patent discloses an insulating tape, CN209652211U, which is characterized in that: the insulating tape includes a single-sided adhesive layer, a base layer and a double-sided adhesive layer, and the double-sided adhesive layer, the base layer and the single-sided adhesive layer are compounded in sequence from top to bottom; the single-sided adhesive layer is a transparent plastic film and a resin adhesive coating coated on the plastic film; the base layer is a basalt fiber fabric and a mixed coating coated on the basalt fiber fabric, and the mixed coating is a mixed material of basalt fiber chopped yarn and resin adhesive. The insulating tape provided by the utility model adopts basalt fiber and basalt fiber chopped yarn, which can increase the electrical insulation properties of the electrical insulating tape; the surface layer of the insulating tape is provided with a plurality of sub-plastic films, and when the surface layer of the insulating tape is stuck with oil stains and other dirt, it is only necessary to tear off the corresponding sub-plastic film to enhance the adhesion between the double-sided adhesive layer and the surface of the base layer, which is conducive to bonding.

[0004] The above scheme has the above advantages, but the disadvantages are: the performance and tensile strength of the insulating tape are relatively poor. The insulating tape will be subjected to a large tensile force when it is installed and used. The tensile strength of the existing insulating tape is poor, and it is easy to be damaged during the pulling process, or it is easy to crack during use, which brings safety hazards. In addition, when using the insulating tape, due to its adhesion and certain toughness, it is generally torn by hand or cut with a knife. It is also necessary to prepare cutting tools when using it, which is more troublesome. Utility Model Content

[0021] The technical effect of adopting the above further solution is: by sliding the sliding block to make it slide with the cutting knife in the sliding groove, the insulating tape can be cut without preparing cutting tools, which is convenient and quick.

[0022] Compared with the prior art, the advantages and positive effects of the utility model are:

When the sliding block is released, the sliding block slides again with the cutting knife under the action of the spring until the cutting knife enters the accommodating groove, which does not affect the subsequent rotation of the tape body.
