Description

Technical Field

[0001] The utility model relates to the technical field of tapes, in particular to an insulating tape with good waterproof effect. Background Technique

[0002] Tapes can be classified according to their functions into: high-temperature tapes, double-sided tapes, insulating tapes, special tapes, pressure-sensitive tapes, die-cut tapes. Different functions are suitable for different industry needs. A layer of adhesive is coated on the surface of the tape to make the tape stick to objects. The earliest adhesives came from animals and plants. In the 19th century, rubber was the main component of the adhesive; while various polymers are widely used nowadays.

[0003] For the current insulating tape with good waterproof effect, when water enters the tape, it will affect the adhesion of the tape. And when using the tape, generally the user needs to use external tools to tear and segment the tape. The remaining tape will re-adhere to the tape, and it is not convenient to find the head of the tape when the tape needs to be torn again. Content of the Utility Model

[0004] The purpose of the utility model is to provide an insulating tape with good waterproof effect to solve the problem that water entering the tape will affect the adhesion of the tape.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: an insulating tape with good waterproof effect, including:

[0006] A body;

[0007] A polytetrafluoroethylene film layer, which is located at the bottom end of the body;

[0008] An adhesive layer, which is arranged at the bottom end of the polytetrafluoroethylene film layer;

[0009] A primer layer, which is located at the bottom end of the adhesive layer;

[0010] A circular hole, which is arranged at the top end of the body;

[0011] An arc-shaped opening, which is located at the top end of the body and at a position on one side of the arc-shaped opening.

[0012] As a further scheme of the utility model: the body and the polytetrafluoroethylene film layer are adhesively connected.

[0013] As a further scheme of the utility model: the polytetrafluoroethylene film layer and the adhesive layer are adhesively connected.

[0014] As a further scheme of the utility model: a plurality of circular notches are equidistantly arranged along the width direction of the body at the arc-shaped opening.

[0015] As a further solution of the present utility model: the arc-shaped opening is semi-circular, and the primer layer and the adhesive layer are adhesively connected.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] 1. By providing a circular hole and an arc-shaped opening, the function of facilitating the tearing of the tape is realized. Pinch the arc-shaped opening, pull the tape and start tearing along one end of the circular hole. When tearing to the other end of the circular hole, the tape is divided into two parts, and another arc-shaped opening is exposed to the outside. At this time, the torn part can be taken off for pasting. When the tape needs to be torn again, pinch the just-exposed arc-shaped opening for tearing again, so as to realize the function of facilitating the tearing of the tape, and thus realize the function of facilitating the search for the head of the tape;

[0018] 2. By providing a polytetrafluoroethylene film layer, the function of preventing water from entering the tape and weakening the adhesiveness of the tape is realized. Since the E-PTFE fabric has excellent waterproof, moisture-permeable and windproof functions, the waterproof performance of the tape can be effectively improved. BRIEF DESCRIPTION OF THE DRAWINGS
