Embodiment 1

[0022] The polyester masking protective tape includes a substrate layer, a release agent layer disposed above the substrate layer, and an adhesive layer disposed below the substrate layer.

[0023] In this embodiment, the adhesive layer is composed of silicone adhesive, and the substrate layer is composed of the following components by weight:

[0024] 78 parts of polyethylene terephthalate, 4 parts of polymethyltriethoxysilane, 3 parts of vinyl phenyl silicone oil, 5 parts of silicone, 3 parts of di-tert-butyl peroxide.

[0025] The preparation method of the above polyester masking protective tape consists of the following steps:

[0026] (1) Heat the polyethylene terephthalate to a molten state;

[0027] (2) After mixing the polymethyltriethoxysilane, vinylphenyl silicone oil and silicone uniformly, add them to the molten polyethylene terephthalate to make a mixture one;

[0028] (3) Under continuous stirring, add di-tert-butyl peroxide to the mixture one, and then make the base materi...

Embodiment 2

[0031] The difference between this embodiment and embodiment 1 is that the content of each component in the substrate layer is different, and the specific parts by weight of each component in the substrate layer are as follows:

[0032] The substrate layer is composed of the following components by weight:

[0033] 80 parts of polyethylene terephthalate, 3 parts of polymethyltriethoxysilane, 3 parts of vinyl phenyl silicone oil, 6 parts of silicone, and 5 parts of di-tert-butyl peroxide.

Embodiment 3

[0035] The difference between this embodiment and embodiment 1 is that the content of each component in the substrate layer is different, and the specific parts by weight of each component in the substrate layer are as follows:

[0036] The substrate layer is composed of the following components by weight:

[0037] 75 parts of polyethylene terephthalate, 5 parts of polymethyltriethoxysilane, 1 part of vinyl phenyl silicone oil, 8 parts of silicone, 4 parts of di-tert-butyl peroxide.

Abstract

The invention discloses shielding and protecting polyester adhesive tape. The adhesive tape mainly solves the problem of existing protecting adhesive tape that adhesive failure occurs often due to temperature and bonding time. The adhesive tape comprises a base material layer, a mold release agent layer arranged over the base material layer, and an adhesive layer arranged under the base material layer, wherein the adhesive layer is formed by a silicone adhesive, and the base material layer is prepared from, by weight, 70-80 parts of polyethylene terephthalate, 1-5 parts of polymethyl triethoxy silane, 1-5 parts of vinyl phenyl silicone oil, 5-10 parts of silicone and 1-5 parts of di-tert-butyl peroxide. The adhesive tape has high tensile resistance and adhesive force, and adhesive failure does not occur after long-time bonding at high temperature.

Description

[0001] technical field [0002] The invention relates to an adhesive tape, in particular to a polyester masking protective adhesive tape. Background technique [0003] Adhesive tape is one of the commonly used fixing and covering tools in daily life and work. According to its function, it can be divided into high temperature tape, medium temperature tape, normal temperature tape, double-sided tape, insulating tape, special tape, pressure sensitive tape, die-cut tape, etc. According to different functions, it is suitable for different places and fields, among which high temperature tape is one of the commonly used tapes. [0004] The protective tape is a protective film, which is a pressure-sensitive adhesive used to protect the surface of the material and prevent scratches and pollution. It is generally made of PET or PE film, coated with acrylic pressure-sensitive adhesive, and usually has a small peeling force. [0005] Due to the influence of the temperature and the len...
