Antistatic release film with light release force

Abstract

The invention discloses an antistatic release film with a light release force. The antistatic release film with the light release force is characterized by comprising a base film layer, wherein a release layer is arranged on the base film layer and formed by coating a release agent, and the release agent comprises the following components in parts by mass: 5 to 10 parts of polyethylene wax particles, 20 to 42 parts of vinyl organic silicon resin, 10 to 18 parts of polyvinyl alcohol, 2 to 5 parts of conductive polymers, 0.2 to 2 parts of pigment, 1 to 5 parts of coupling agents, 0.5 to 3 parts of defoaming agents, and 10 to 25 parts of solvents. The release film has the excellent antistatic ability, and further contains the polyethylene wax particles, so that the surface composition of the release film is changed, the surface lubricity of the release film is improved, the stereoscopic sense and glossiness of the release film are increased, and then the obtained release film is relatively light and stable in release force. In addition, the polyethylene wax particles are excellent in wear resistance, thus the anti-scratch performance of the release film can be improved.

Description

technical field

[0001] The invention relates to a release film, in particular to an antistatic release film with light release force. 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 characteristics of the...
