Problems solved by technology

[0002] With the development of science and technology, the requirements for protective films of electronic products are also increasing. When the existing protective films are attached to graphite or electronic products, they are prone to fall off, reverse peeling or destroy the structure of the attached object, resulting in economic losses; On the other hand, the compatibility of existing protective films is low, especially for low cohesion objects, which will easily cause matching errors when selecting protective films; Mutual interference affects the amount of factors, not only is easy to peel off and affects the service life, but also further affects the performance of the protective film, resulting in poor conductivity, easy to be affected by static electricity, and low performance; and the existing protective film in the state of conventional rubber surface is exhausted Therefore, protective films in the die-cutting industry, graphite or graphene, or the electronics industry still have huge economic market prospects

Embodiment 1

[0047] Such as figure 2 and 3 As shown, the dot-matrix PET protective film of this product is composed of hemispherical first bumps 3, semi-elliptical second bumps 4 and PET substrate, and has the characteristics of uniformly distributed dot arrays;

[0048] The PET base material is prepared by the net roll body 5 and the pressure roll 6 coated with silica gel to obtain the dot matrix PET protective film of this product.

Embodiment 2

[0050] Such as Figure 4 and Figure 5 As shown in the figure, it is composed of a hemispherical first bump 3, a semi-elliptical second bump 4 and a PET substrate. figure 2 and 3 The first bump 3 and the second bump 4 are obtained by rotating 45°. In actual production, due to the effect of surface tension, after the silica gel falls from the mesh roller body 5 and bonds with the PET substrate, it will deform, so it will Produces inconsistent bumps and greatly reduces compatibility with graphite or electronics.

Embodiment 3

[0052] Such as Figure 6~9 As shown in the figure, it is composed of a hemispherical first bump 3, a diamond-shaped second bump 4 and a PET substrate, such as Figure 6 Rotate each point in 45° to get Figure 7 , Figure 8 Rotate each point in 45° to get Figure 9 , in actual production, due to the effect of surface tension, after the silica gel falls from the mesh roller body 5 and bonds with the PET substrate, some deformations will occur, and some bumps will become similar to those after curing. Figure 2~5 The corresponding shape in , so the effect in Example 2 will be produced, figure 2 and image 3 The dot matrix distribution is more high-performance, high compatibility, and ultra-high exhaust.

Abstract

The invention discloses a dot-matrix PET protective film which comprises a base material layer; a salient point layer is fixed on the base material layer, the salient point layer comprises a plurality of first salient points and second salient points, the first salient points and the second salient points are uniformly distributed, and the top points of the first salient points and the top points of the second salient points are on the same plane. The dot-matrix PET protective film has the advantages of high performance, high compatibility, ultrahigh exhaust property and reworkability.

Description

technical field [0001] The invention relates to the field of film technology, in particular to a dot-matrix PET protective film and an anvil roll for the same. Background technique [0002] With the development of science and technology, the requirements for protective films of electronic products are also increasing. When the existing protective films are attached to graphite or electronic products, they are prone to fall off, reverse peeling or destroy the structure of the attached object, resulting in economic losses; On the other hand, the compatibility of existing protective films is low, especially for low cohesion objects, which will easily cause matching errors when selecting protective films; Mutual interference affects the amount of factors, not only is easy to peel off and affects the service life, but also further affects the performance of the protective film, resulting in poor conductivity, easy to be affected by static electricity, and low performance; and the...
