Problems solved by technology
[0002] Due to its strong moisture absorption and air permeability, good resilience, no static electricity and excellent aging resistance, the acetate cloth tape made of composite tape has high temperature resistance, anti-aging, soft and docile, acid and alkali resistance and anti-mildew, etc. Its insulation performance is better than ordinary glass fiber cloth and glass cloth, so it is widely used in the manufacturing fields of TV sets, transformers, air conditioners and computers. However, the double-layer PET fiber composite tapes on the market today have poor high temperature resistance. The highest temperature cannot exceed 80 degrees, the stability is poor, the glue is easy to remain, and there are certain limitations in use. Therefore, we propose a high-temperature resistant double-layer PET fiber composite tape to solve the above problems

Embodiment
[0013] refer to figure 1 , a high-temperature-resistant double-layer PET fiber composite tape, comprising a non-silicon release layer 1, a first PET fiber layer 2, a polyester substrate 3 and a second PET fiber layer 4, the non-silicon release layer 1 , the first PET fiber layer 2, the polyester substrate 3 and the second PET fiber layer 4 are sequentially pasted together along the thickness direction of the composite tape, and the heat insulation layer 1 and the second PET fiber layer 4 are far away from each other. Both sides are bonded with a high temperature resistant layer 5 .
[0014] In this embodiment, the non-silicon-coated release layer 1 is made of an inert element release agent, and the thickness of the non-silicon-coated release layer 1 is 5um-18um, and the polyester substrate 3 is made of PET material , and the thickness of the polyester substrate 3 is 20um-80um, and the first PET fiber layer 2 and the second PET fiber layer 4 are both made of polyethylene terep...

The invention relates to the technical field of composite adhesive tapes, in particular to a high temperature resistant double-layer PET fiber composite adhesive tape to solve the problem that double-layer PET fiber composite adhesive tapes on the market nowadays have poor high temperature resistance, the maximum temperature cannot exceed 80 DEG Cs, the stability is poor and the residue is easilycaused. The high temperature resistant double-layer PET fiber composite adhesive tape comprises a non-silicon coated release layer, a first PET fiber layer, a polyester substrate and a second PET fiber layer. The non-silicon coated release layer, the first PET fiber layer, the polyester substrate and the second PET fiber layer are successively glued together in the thickness direction of the composite adhesive tape. One side of a heat insulating layer, far from the second PET fiber layer, is glued with a high temperature resistant layer. The adhesive tape has a reasonable design and layout, and the problem that a traditional adhesive tape has poor high temperature resistance and is hard to use at 80 DEG C and above. Thereby, the composite adhesive tape is more resistant to high temperature, has stronger stability, can be used at higher temperature, and is resistant to acid and alkali. In addition, the preparation process is simple, is low-cost, and is widely applied.
