Abstract

The invention belongs to the field of protective films, and relates to a polyester film protective film, which comprises a polyester film and a pressure-sensitive adhesive layer coated on the surfaceof the polyester film, the resistance of the pressure-sensitive adhesive layer is less than 10<10> ohm / square; the pressure-sensitive adhesive layer contains acrylate resin; the acrylate resin is prepared from a long-chain acrylic monomer, a fluorine-containing acrylic monomer, an acrylate hard monomer, an acrylate soft monomer and an acrylate functional monomer through free radical polymerization. According to the technical scheme, wettability and optical performance of the surface of the optical component can be considered at the same time.

Description

technical field [0001] The invention belongs to the field of protective films and relates to a polyester film protective film. Background technique [0002] In order to make the surface of optical components have special functions, functional coatings are usually coated on the surface of optical components, such as: hardening layer, antifouling layer, antiglare layer, antistatic layer, high fog layer, diffusion layer, etc. In order to prevent optical components with functional coatings from being polluted and scratched during assembly or transportation, an optical protective film needs to be pasted on the surface of the optical device. Due to the low surface energy of the functional coating, the wettability of the protective film is poor, and it is easy to generate air bubbles during the lamination process, making it difficult to attach and the peeling force is significantly reduced. Therefore, a protective film with good wettability is required. [0003] Although the prior...
