▎ 摘  要

NOVELTY - Antistatic optical grade release film comprises a substrate layer (10) and a release agent layer (20), where the substrate layer is provided with an antistatic layer (30) on the side opposite to the release agent layer, and the antistatic layer comprises 50-150 pts. wt. acrylic resin, 5-10 pts. wt. dimethyl silylated silica, 3-8 pts. wt. polyquaternary ammonium salt, 5-10 pts. wt. graphene, 2-5 pts. wt. melamine, and 100-300 pts. wt. ethylene glycol. USE - As antistatic optical grade release film. ADVANTAGE - The antistatic optical grade release film is flexibly applied online or offline to the production equipment, has excellent strength, is simple in production process, does not need to modify the equipment, and greatly facilitates the deployment of production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the antistatic optical grade release film comprising substrate layer and a release agent layer, comprising adding acrylic resin, dimethyl silylated silica, polyquaternary ammonium salt, graphene, melamine, and ethylene glycol, after mixing, stirring for 20-30 minutes according to the parameters of 800-1000 rpm, using a 260-300 mesh screen to filter, coating on the surface of the substrate layer by spin coating or spraying, and drying at 100 degrees C for 5 minutes to obtain the product. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the antistatic optical grade release film. Substrate layer (10) Release agent layer (20) Antistatic layer (30)
