[0002] The Teflon tape first uses glass fiber as the base fabric, and is coated with Teflon emulsion and then dried to make Teflon fiberglass cloth. It is then made into a tape by secondary coating with silicone adhesive. It is widely used in industries such as packaging, thermoplastics, compounding, sealing and heat sealing, electronics and electricity.
[0003] As a kind of insulating tape, the Teflon tape is often used by electricians. However, when electricians want to ensure the firmness and waterproofness of the connection of circuits and electronic components, when using the Teflon tape, they often stretch and wind the tape to ensure that the tape is wound and adhered more tightly. After the tape is stretched, the adhesive layer on it is pulled loose, resulting in a decrease in the adhesion ability of the adhesive layer, and then reducing the service life of the tape. Therefore, an anti-aging Teflon tape is proposed. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] This part will describe the specific embodiments of the present utility model in detail. The preferred embodiments of the present utility model are shown in the drawings. The function of the drawings is to supplement the description in the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be construed as a limitation on the protection scope of the present utility model.
[0021] Please refer to Figures 1-4, the utility model provides a technical solution: an anti-aging Teflon tape, including a tape loop 2, on the surface of the tape loop 2 there is a tape body 1, the tape body 1 includes an adhesive layer 140, the adhesive layer 140 is arranged in a wavy shape, so that after the tape body 1 is stretched subsequently, the area of the adhesive layer 140 can be correspondingly enlarged, so that the adhesive layer 140 can adhere to a larger area, avoiding the situation that after the tape body 1 is stretched, the adhesive layer 140 becomes relatively loose, resulting in the weakening of the adhesion ability of the adhesive layer 140, thereby improving the adhesion ability of the tape body 1 and the use effect of the device, which is worthy of promotion.
[0022] On the top of the adhesive layer 140 there is a base layer 130, on the top of the base layer 130 there is a protective layer 120, on the top of the protective layer 120 there is a non-stick layer 110, the material of the non-stick layer 110 is a silicone release film, thus avoiding the tape body 1 from sticking to each other during the winding process, thereby affecting the normal use of the tape body 1 subsequently. At the same time, the silicone release film is a material with excellent heat resistance and flexibility, thereby improving the heat resistance performance of the tape body 1, enabling it to still be used normally in a high-temperature environment.
[0023] Furthermore, the protective layer 120 includes a reinforcing layer 121 and an anti-aging layer 122, the reinforcing layer 121 is arranged at the bottom of the non-stick layer 110, the anti-aging layer 122 is arranged at the bottom of the reinforcing layer 121, the material of the reinforcing layer 121 is a thermoplastic composite fiber layer, which can strengthen the tape body 1, so that the tape body 1 will not be broken during the stretching process, thereby improving the use effect of the tape body 1. At the same time, because the thermoplastic composite fiber layer has a certain elasticity, it does not prevent the subsequent staff from stretching the tape body 1 during use.
[0024] The material of the anti-aging layer 122 is a PE film, which has high weather resistance, thereby delaying the aging speed of the tape body 1 and increasing the service life of the tape body 1.
[0025] The base layer 130 includes a temperature-resistant layer 131, a polytetrafluoroethylene film 132 and a non-woven fabric layer 133, the temperature-resistant layer 131 is located at the bottom of the anti-aging layer 122, the polytetrafluoroethylene film 132 is located at the bottom of the temperature-resistant layer 131, the non-woven fabric layer 133 is located at the bottom of the polytetrafluoroethylene film 132, the material of the temperature-resistant layer 131 is a TPEE high-temperature resistant elastic film, with good toughness, water resistance, aging resistance, weather resistance and other characteristics, further improving the anti-aging effect of the tape body 1, and at the same time improving the high-temperature resistance effect of the tape body 1, which is worthy of promotion.
[0026] Furthermore, the polytetrafluoroethylene film 132 is arranged in a wavy shape, so that the polytetrafluoroethylene film 132 can be stretched synchronously during the stretching process of the tape body 1, avoiding the breakage of the polytetrafluoroethylene film 132 and ensuring the normal use of the tape body 1.
[0027] A cavity 134 is provided between the polytetrafluoroethylene film 132 and the heat-resistant layer 131, and nano-pores 135 are formed on the surface of the polytetrafluoroethylene film 132. Furthermore, through the settings of the nano-pores 135 and the cavity 134, a space for the heat at the position adhered by the tape body 1 to dissipate heat outward is provided, thus avoiding the situation where heat cannot dissipate, reducing the usage condition of electronic components, and further improving the usage effect of the device, which is worthy of popularization.
[0028] Furthermore, the non-woven fabric layer 133 is also arranged in a wavy shape, and the adhesive layer 140 is coated on the non-woven fabric layer 133 to provide an attachment position for the adhesive layer 140. At the same time, due to the certain gaps in the non-woven fabric layer 133 itself, heat can be dissipated outward, ensuring the normal use of the device.
[0029] Specifically, when adhering wires and electronic components, etc., the staff stretches the tape body 1, and then stretches the polytetrafluoroethylene film 132, the non-woven fabric layer 133 and the adhesive layer 140 to gradually flatten them, so that the adhesive layer 140 can adhere to a larger area, avoiding the situation where the adhesive layer 140 on the tape body 1 becomes sparse after stretching the tape body 1, and thus avoiding the situation of the bonding strength of the tape body 1, and further improving the overall usage effect of the tape, which is worthy of popularization.
[0030] Working principle: When adhering wires and electronic components, etc., the staff stretches the tape body 1, and then stretches the polytetrafluoroethylene film 132, the non-woven fabric layer 133 and the adhesive layer 140 to gradually flatten them, so that the adhesive layer 140 can adhere to a larger area.
[0031] The above has described the embodiments of the present invention in detail with reference to the drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field.
