Abstract

The invention discloses a stain-resistant release film with small release force. The stain-resistant release film comprises a base film layer; the base film layer is provided with a release layer; the release layer is formed via coating of a release agent; and the release agent comprises, by mass, 5 to 10 parts of polyethylene wax particle, 18 to 38 parts of vinyl organosilicone resin, 5 to 12 parts of fluorine-containing polysiloxane, 2 to 7 parts of polyvinyl alcohol, 0.1 to 2.5 parts of a pigment, 2 to 5 parts of an antioxidant, 2.5 to 5 parts of a coupling agent, 0.5 to 3 parts of an antifoaming agent, and 16 to 32 parts of a solvent. Cooperation of the ingredients is capable of providing the stain-resistant release film with excellent stain resistance; adding of the polyethylene wax particle is capable of changing surface composition of the stain-resistant release film, improving the lubricating properties, the stereoscopic impression, and the lustrousness of the surface of the stain-resistant release film, and providing the stain-resistant release film with small and stable release force; and at the same time, the polyethylene wax particle possesses excellent wear resistance, so that the scrath resistance of the stain-resistant release film is improved.

Description

technical field [0001] The invention relates to a release film, in particular to a release film with light release force and stain resistance. Background technique [0002] Release film, also known as anti-adhesive film, is based on polyethylene terephthalate plastic (PET for short), biaxially oriented polypropylene film plastic (BOPP for short), polyethylene plastic (PE for short), and carbonate plastic (PET for short). PC), polystyrene plastic (referred to as PS), polypropylene plastic (abbreviated as CPP) is a material with low surface energy on the surface. When the adjacent adhesive is peeled from the release surface, the release material can be easily peeled off or removed without damaging the physical properties of the adhesive. The release film is characterized by smooth surface, high cleanliness, stable size in subsequent processing, adjustable transparency and color, and a wide range of options for film thickness and substrate types. Utilizing these characteristi...
