Abstract

The invention belongs to the technical field of functional polyester films, and particularly relates to an uvioresistant coating liquid for a polyester film as well as a preparation method and an application thereof. The uvioresistant coating liquid for the polyester film comprises the following components in parts by weight: 20-40 parts of titanate alcoholic liquid, 50-80 parts of water-based thermoset acrylic resin, 1-10 parts of aliphatic isocyanate, 1-5 parts of surface tension additive and 100-200 parts of deionized water, wherein the concentration of the titanate alcoholic liquid is 0.1-0.2 g / ml. The preparation method comprises the following steps: preparing a basic liquid; preparing a titanate alcoholic liquid; and mixing the liquids to obtain the coating liquid. The coating liquid is coated on a biaxial stretching polyester film through an online coating process to obtain the polyester film with the uvioresistant function. The technical liquid is high in coating efficiency and strong in uvioresistant performance, maintains high light transmittance, overcomes the problem of yellowing of polyurethane ink, and is simple, easy and feasible to operate.

Description

technical field [0001] The invention belongs to the technical field of functional polyester films, and in particular relates to an anti-ultraviolet coating solution for polyester films, a preparation method and application thereof. Background technique [0002] In the prior art, the anti-ultraviolet function of glass is usually solved by sticking a film or glass coating, and the sticking film can effectively block more than 90% of ultraviolet rays. For automotive glass, people in the car are irradiated by excessive ultraviolet rays, which will accelerate skin aging and burn the skin, and the facilities in the car will also accelerate aging and shorten the service life when exposed to ultraviolet rays. Therefore, there is an urgent need for high anti-ultraviolet film. application. [0003] At present, biaxially oriented polyester film is generally used as the base material of the film, and the biaxially oriented polyester film BOPET film has the characteristics of high stren...
