Antistatic optical release film for polaroid and preparation method of antistatic optical release film

Abstract

The invention discloses an antistatic optical release film for a polaroid. The antistatic optical release film comprises a release layer, a base material layer and an antistatic layer from top to bottom, and the release layer comprises the following components in parts by weight: 20-40 parts of vinyl polydimethylsiloxane, 3-8 parts of hydrogen-containing polysiloxane, 0.5-1.5 parts of an anchoring agent, 0.05-0.2 part of chemically modified inorganic particles, 3-8 parts of fluorine modified organic silicon resin, 2-4 parts of a platinum catalyst and 130 parts of an organic solvent. The release film has the characteristics of stable release force, low quick release force, antistatic property, high light transmittance, high residual adhesion rate and the like, is mainly used for protecting and transporting pressure-sensitive adhesive layers of polaroid products, does not generate static electricity to adsorb dust in polaroid transportation and downstream production, does not generate bad bubbles in use, and the release film cannot be quickly stripped in the downstream manufacturing process to cause poor stripping and influence the yield.

Description

[Technical field]

[0001] The present invention relates to the technical field of exemplary membranes, in particular, a preparation method thereof, in particular, of the preparation method thereof. 【Background technique】

[0002] The polarizing plate is called a partial light sheet, typically consisting of a protective film layer, a TAC film layer, a PVA film layer, a TAC film layer, a pressure-sensorized layer, a membrane layer, and is an important part of a liquid crystal display imaging, in order to protect polarizing plates. The medium pressure sensitive adhesive layer is not contaminated during the product transportation process and the production process, and it is necessary to bond the appropriate optical release film to protect the pressure sensitive adhesive layer in polarizer products; this layer of optical release film requirement Stable induction force, strong PSA adapter, high residual start rate, high level of flatness, high wideness, etc.; and need to leave the memb...
