Description

Technical Field

[0001] This utility model relates to the field of adhesive tape technology, specifically to a pressure-sensitive adhesive tape based on a PET base film. Background Technology

[0002] With the rapid improvement of the new energy industry, energy storage industry, and industrial and consumer precision electronics industry, adhesive tape has been fully integrated into the production and use of these fields.

[0003] Adhesive tape is widely used in almost every industry, including consumer electronics, new energy power, commercial and industrial energy storage, and industrial equipment. The structure of adhesive tape generally includes a substrate layer, an adhesive layer coated on the substrate layer, and a release material layer used to protect the surface of the adhesive layer.

[0004] However, existing tapes have a single function, only having an adhesive function. However, the above-mentioned equipment often experiences micro-vibrations during use, and existing tapes can only perform adhesive bonding and do not have waterproof, dustproof, or shock-absorbing functions, which limits the application of tapes. Utility Model Content

[0005] (I) Problems to be solved

[0006] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a pressure-sensitive tape based on a PET base film that is easy to operate and use, has a buffer function, is waterproof and dustproof, and is easy to die-cut.

[0007] (II) Technical Solution

[0008] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a pressure-sensitive adhesive tape based on a PET base film, comprising a PET base layer, a buffer protective layer connected to the upper part of the PET base layer, a pressure-sensitive adhesive layer one on the top of the buffer protective layer, a pressure-sensitive adhesive layer two connected to the bottom of the PET base layer, an outer protective film layer connected to the bottom of the pressure-sensitive adhesive layer two, and a tear-resistant layer filled inside the buffer protective layer. The thickness of the pressure-sensitive adhesive tape is 0.05mm to 0.45mm.

[0009] As an improvement, the outer protective film layer is a release film or release paper.

[0010] As an improvement, the buffer layer is a PP buffer layer made of PP material, and the tear-resistant layer is located in the middle of the PP buffer layer.

[0011] As an improvement, the tear-resistant layer is made of high-elasticity yarn, comprising multiple sets of interwoven warp and weft threads.

[0012] (III) Beneficial Effects

[0013] The advantages of this utility model compared with the prior art are as follows: In this application, PET material is used as the base layer, and PP buffer layer is used in conjunction to form the base of the tape, thereby completing the buffer bonding of the equipment and having a certain buffering effect. In order to ensure the strength of the tape, an additional tear-resistant layer is set to improve the tear resistance of the tape, further increasing the performance of the tape and ensuring the application effect. At the same time, the PET bottom film plays a barrier role, preventing water molecules and dust from easily passing through. Due to the characteristics of the PET substrate itself, die-cutting of extremely narrow shapes is easier and better yield is obtained. Attached Figure Description
