Problems solved by technology

[0003] At present, PET electrostatic film is often used, but this type of electrostatic film has high hardness, good shape retention, and is not easy to bend. When the surface is damaged, it is easy to warp and cannot meet the requirements of use
[0004] For this reason, a glue-coated electrostatic film has been developed. This glue-coated electrostatic film is made of a soft substrate and coated with an adhesive on the surface of the substrate. It is used for curved surfaces such as special-shaped and large corners. It is not easy to warp on the surface, but it cannot be pasted and peeled off repeatedly, and it is easy to degumming when peeling off, leaving white mist and residual glue and other foreign matter on the surface of the adhesive, which affects the performance

Abstract

The invention discloses a PVC (Polyvinyl Chloride) low-viscosity self-adhesive static protective film comprising a first base material layer, a second base material layer and a third base material layer, wherein the second base material layer is arranged between the first base material layer and the third base material layer; the second base material layer is a PVC resin thin film layer; and the first base material layer and the third base material layer are PVC resin self-adhesive layers. With the adoption of the manner, the static protective film disclosed by the invention can be adhered to a product through static adsorption to have the surface protection and antistatic functions; the PVC low-viscosity self-adhesive static protective film is low in adhesive force, can be repeatedly fitted and stripped, is not degummed in a stripping process, has no residual rime fog, and is soft; and the PVC low-viscosity self-adhesive static protective film can be used for arc-shaped surfaces with a special shape, a large corner and the like, and can not raise.

Description

technical field [0001] The invention relates to the field of protective films for electronic products, in particular to a PVC low-viscosity self-adhesive electrostatic protective film. Background technique [0002] At present, double-sided electrostatic film is mainly used for the protection of LCD light guide plate, die-cutting of diffuser, acrylic, PC, PET, glass plate, mobile phone lens, digital camera lens, and high-gloss injection plastic shell, etc. Static electricity is not felt. [0003] At present, PET electrostatic film is often used, but this type of electrostatic film has high hardness, good shape retention, and is not easy to bend. When the surface is damaged, it is easy to warp and cannot meet the requirements of use. [0004] For this reason, a glue-coated electrostatic film has been developed. This glue-coated electrostatic film is made of a soft substrate and coated with an adhesive on the surface of the substrate. It is used for curved surfaces such as sp...
