[0017] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.
[0018] Example 1
[0019] This utility model provides a highly flame-retardant tape, such as Figures 1 to 3As shown, the tape includes: a tape core 1 and a tape body 2. The tape body 2, from bottom to top, is composed of an inner release film 201, a release coating 202, a first adhesive layer 203, an aluminum foil layer 204, a second adhesive layer 205, a mica-fiberglass composite layer 206, a third adhesive layer 207, a polyester insulating layer 208, and an outer protective film layer 209. The inner release film 201 has a thickness of 25-35 micrometers and is made of PET material. It is used to protect the adhesive surface of the tape. When in use, peeling off the inner release film 201 exposes the adhesive layer of the tape. The release coating 202 is provided at the top of the inner release film 201. The first adhesive layer 203 is bonded to the top of the release coating 202. The aluminum foil layer 204 is bonded to the top of the first adhesive layer 203. A second adhesive layer 205 is bonded to the top of the foil layer 204. A mica-fiberglass composite layer 206 is bonded to the top of the second adhesive layer 205. The mica-fiberglass composite layer 206 is composed of alternating layers of mica sheets and fiberglass. A third adhesive layer 207 is bonded to the top of the mica-fiberglass composite layer 206. The first adhesive layer 203, the second adhesive layer 205, and the third adhesive layer 207 are all made of acrylic polymer as the main adhesive, making the tape easy to peel off after being bonded to the product surface and leaving little residue, without damaging the product surface. A polyester insulating layer 208 is bonded to the top of the third adhesive layer 207. An outer protective film layer 209 is provided at the top of the polyester insulating layer 208. The outer protective film layer 209 is made of ETFE film material.
[0020] like Figure 2 and Figure 3 As shown, the polyester insulating layer 208 is yellow. The polyester insulating layer 208 includes a polyester film 2081 disposed on the top of the third adhesive layer 207. An insulating coating 2082 is disposed on the top of the polyester film 2081 and is disposed at the bottom of the outer protective film layer 209. The polyester insulating layer 208 itself has excellent electrical insulation properties, which can effectively isolate current. Its bright yellow color design is easy to identify and serves as a safety warning to workers.
[0021] like Figures 1 to 3 As shown, tape protectors 3 are fixedly fitted to both ends of the tape core 1. First, one tape protector 3 is fixedly fitted to one end of the tape core 1. Then, the tape is wound around the tape core 1 one turn at a time. Next, the other tape is fitted to the other end of the tape core 1. Thus, the tape wrapped around the tape core 1 is wrapped between the two tape protectors 3, ensuring the integrity of the tape and preventing the tape from being worn, making it convenient for storage and use.
[0022] Working principle: When in use, tear open the inner release film 201, and the tape is bonded to the surface of the product to be bonded through the action of the first adhesive layer 203. The aluminum foil layer 204, which has high reflectivity and thermal conductivity, can quickly disperse heat and delay the damage of high temperature to local structures. The mica-glass fiber composite layer 206, with its layered structure of mica, can block the diffusion of oxygen and combustible gases. At the same time, glass fiber, as an inorganic material, cannot be burned and can isolate flames. The polyester insulation layer 208 can effectively isolate current and prevent short circuits or leakage.
[0023] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
