Abstract

The invention discloses an optical fluorine-containing polyurethane acrylate UV-curable monomer and a preparation method thereof. The chemical structure of the monomer is represented by a general formula shown in the specification. The preparation method of the monomer comprises the following steps: 1, adding a hexasubstituted phenylhexafluoropropane structure monomer and dihydric alcohol into a reaction apparatus, reacting under the action of a catalyst for 1-4h, and stopping the reaction when the water yield reaches 80-98% of the theoretic water yield to obtain a dicarboxyl-terminated prepolymer; 2, continuously adding diamine to the reaction apparatus, and reacting under the action of a catalyst for 1-3h to obtain a diamino-terminated prepolymer; and 3, adding an acrylic monomer into the diamino-terminated prepolymer, and esterifying under the action of a catalyst for 1-5h. The optical fluorine-containing polyurethane acrylate UV-curable monomer has good heat, ageing and scratch resistance and excellent optical performances, and is suitable for surface coating of fluorine-containing polymers, such as fluorine-containing modified PET bidirectional stretching optical films.

Description

technical field [0001] The invention relates to the field of optical films, in particular to an optical fluorine-containing polyurethane acrylate UV curing monomer and a manufacturing method thereof. Background technique [0002] Fluoropolymers have been widely used in various fields of industrial production because of their excellent chemical stability, heat resistance, electrical insulation, self-lubrication, non-stickiness, and atmospheric aging resistance. . However, due to the chemical inertness and extremely low surface energy of fluorine-containing polymers, it is difficult for general coatings to be suitable for the coating of fluorine-containing polymer films. However, by taking advantage of the special properties of fluoropolymers, many coating materials with self-cleaning properties have been developed, which are widely used in the anti-fingerprint, anti-fouling, and anti-scratch fields of liquid crystal displays, mobile phones, and tablet computer screens.
