[0002] Insulating tape generally refers to the tape used by electricians to prevent leakage and act as an insulator. It is mainly composed of a base tape and a pressure-sensitive adhesive layer. With the advancement of science and technology and economic development, more and more types of insulating tapes are widely used in electrical work such as wire wrapping, joints, insulation sealing, etc.

[0003] However, the existing insulating tapes still have certain defects. Some existing insulating tapes will add a certain amount of heavy metal compounds during the production process, which will not only cause environmental pollution, but also affect the health of operators. In addition, the existing insulating tapes have a relatively simple functional structure and low tensile strength, which cannot meet the use requirements in different actual situations. Therefore, an environmentally friendly insulating tape is proposed. Utility Model Content

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An environmentally friendly insulating tape comprises: a tape reel, the outer surface of which is wound with a tape strip, wherein the tape strip is composed of a waterproof layer, an ultraviolet protection layer, a high temperature resistant layer, a thermochromic layer, an organic silica gel layer and an adhesive layer which are compounded in sequence.

[0007] Preferably, the high temperature resistant layer is made of polyetheretherketone, and the high temperature resistant layer is configured as a transparent structure.

Through the design of the organic silicone layer and the high temperature resistant layer on the tape strip, the organic silicone layer and the high temperature resistant layer composed of polyetheretherketone have excellent characteristics such as high and low temperature resistance, electrical insulation, non-toxic and tasteless, and physiological inertness, so that they can replace the use of heavy metal compounds, so that they can better meet the use requirements of the tape and improve the environmental performance of the tape;

[0014] And through the design of waterproof layer and anti-ultraviolet layer, it can play a better protective role on the surface of the wire, which increases safety during use and helps to extend the service life of the tape.

[0015] 2.

[0017] 3. Through the design of wear-resistant strips and anti-slip strips, the wear-resistant strips can provide better wear resistance for the middle part of the tape, which can increase the service life and tensile resistance of the tape during use, and avoid damage during use.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 2 , the utility model provides the following technical solutions:

[0023] like Figure 1 As shown, an environmentally friendly insulating tape includes: a tape reel 7, a tape strip 8 is wound around the outer surface of the tape reel 7, and the tape strip 8 is composed of a waterproof layer 6, an ultraviolet protection layer 5, a high temperature resistant layer 4, a thermochromic layer 3, an organic silicone layer 2 and an adhesive layer 1 in sequence.

[0024] The high temperature resistant layer 3 is made of polyetheretherketone, and the high temperature resistant layer 3 is set to a transparent structure.

[0025] Through the design of the organic silicone layer 2 and the high temperature resistant layer 4 on the tape strip 8, the organic silicone layer 2 and the high temperature resistant layer 4 composed of polyetheretherketone have excellent properties such as high and low temperature resistance, electrical insulation, non-toxicity, tastelessness and physiological inertness, so that they can replace the use of heavy metal compounds, so that they can better meet the use requirements of the tape and improve the environmental performance of the tape;

[0026] Furthermore, through the design of the waterproof layer 6 and the anti-ultraviolet layer 5, a better protective effect can be provided on the surface of the wire, thereby increasing safety during use and helping to extend the service life of the tape.

[0027] like Figure 1 As shown, the thermochromic layer 4 is formed by mixing temperature-sensitive powder or temperature-variable powder with polypropylene or soft polyvinyl chloride and extrusion molding.

[0028] The waterproof layer 6 and the UV protection layer 5 are respectively made of polypropylene and polyimide, and are arranged to be transparent structures.

[0029] By setting the thermochromic layer 3, when the tape strip 8 is wound around the surface of the wire, the exposed copper wire will heat up and transmit the heat to the thermochromic layer 3 through the organic silicone layer 2, and the thermochromic layer 3 will change color after being heated. After the color changes, it will pass through the high temperature resistant layer 4, the UV protection layer 5 and the waterproof layer 6 which are set as transparent structures and be conspicuously displayed in front of the user, and the user can accurately observe the current exposed position of the copper wire, so that it is convenient for the staff to accurately wrap the tape strip 8 again and cover the exposed position of the copper wire, which can play a good role of temperature indication and reminder during use;

[0030] A high temperature resistant layer 4 is provided on the upper layer of the thermochromic layer 3, so as to avoid heat being blocked inside and heat being conducted to the surface of the outermost waterproof layer 6, thereby avoiding the occurrence of scalding.

[0031] like Figure 2 As shown, the upper surface of the waterproof layer 6 is provided with a wear-resistant strip 601 and an anti-slip strip 602 protruding therefrom.

[0032] The wear-resistant strip 601 is located in the middle of the waterproof layer 6 .

[0033] Through the design of the wear-resistant strip 601 and the anti-slip strip 602, the wear-resistant strip 601 can provide better wear resistance for the middle part of the tape, thereby increasing the service life and tensile resistance of the tape strip 8 during use and avoiding damage during use, while the anti-slip strip 602 can provide anti-slip effect on the surface of the wire and also increase the tightness of the connection when the tapes overlap.

[0034] According to the above technical solution, the working steps of this solution are summarized and sorted out:

[0035] When the tape strip 8 is wound around the surface of the wire, the exposed copper wire will heat up and transmit the heat to the thermochromic layer 3 through the organic silicone layer 2. The thermochromic layer 3 will change color after being heated. After the color changes, it will pass through the high temperature resistant layer 4, the UV protection layer 5 and the waterproof layer 6 which are set as transparent structures and be conspicuously displayed in front of the user. The user can accurately observe the current exposed position of the copper wire, so that it is convenient for the staff to accurately wrap the tape strip 8 again and cover the exposed position of the copper wire, which can play a good role of indicating temperature and reminding during use.

[0036] When the waterproof layer 6 is wound multiple times, the raised anti-slip strips 602 on the surface can increase the tightness of the connection when the tape strips 8 overlap;

[0037] The outermost waterproof layer 6 and the anti-ultraviolet layer 5 can play a better protective role on the surface of the wire, increase the safety during use, and help to extend the service life of the tape.

[0038] In summary: the use of heavy metal compounds is eliminated, so that it can better meet the use requirements of the tape, and the environmental performance of the tape can also be improved. After the tape strip is wrapped, the high temperature will produce color changes, which can play a good role in temperature indication and reminder during use. The anti-slip strip on the surface can play an anti-slip role after being wrapped around the surface of the device, which increases the tightness of the connection when the tape is overlapped.
