Embodiment 1

[0022] 1) Preparation of in-situ polymerized titanium dioxide / polyester composite particles:

[0023] Add ethylene glycol into the reaction kettle, add terephthalic acid and various additives while stirring to prepare a slurry, pressurize to 0.2MPa under nitrogen protection; control the internal temperature of the reaction kettle to 230-250°C, and the esterification reaction At the end, the pressure is reduced to normal pressure, the temperature is lowered to 230°C, and then nano-titanium dioxide is added to disperse evenly in ethylene glycol, and then added to the reaction kettle, and the temperature is raised to 260°C. After low vacuum and high vacuum stages, the temperature in the polycondensation kettle is controlled to 275 -285°C, the vacuum degree is less than 30Pa, after reaching the required viscosity, inject nitrogen gas to pressurize and discharge, and granulate to obtain composite particles. The average particle size of the particles is controlled at 5 μm, and the co...

Abstract

The invention belongs to the field of high molecular materials, and particularly relates to an anti-dazzling thin film and a preparing method of the anti-dazzling thin film. The anti-dazzling thin film comprises a base material and an anti-dazzling layer arranged on the base material in a coating mode. The anti-dazzling layer comprises, by weight, 50-60 parts of water-based acrylic resin, 30-40 parts of acrylic acid monomer, 8-13 parts of in situ polymerization titanium dioxide / polyester compound particle and 3-8 parts of photoinitiator. The preparing method comprises the following steps of preparing the in situ polymerization titanium dioxide / polyester compound particle, preparing ultraviolet light polymerization coating liquor and coating a film through a spinning coating mode. According to the technical scheme, the anti-dazzling layer is formed by coating of the water-based ultraviolet light polymerization coating liquor with the in situ polymerization titanium dioxide / polyester compound particles with the anti-dazzling function, the compatibility of the anti-dazzling layer and the base material is good, the anti-dazzling effect is obvious, and the anti-dazzling thin film has wide market prospects.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to an anti-glare film and a preparation method thereof. Background technique [0002] Glare is an important factor affecting vision, and it depends on the position and brightness of the light source. There are many potential glare light sources in the surrounding environment. Because glare has a great impact on people's normal life and work, in order to effectively overcome the impact of glare, glare must be eliminated. [0003] For the display screen, the glare mainly comes from two aspects, one is that the display screen itself shines brightly, and the other is the reflected glare generated by the external light on the display screen. Especially the reflected glare will seriously affect the normal display, so that the display performance is greatly reduced. [0004] The current solution is to use a soft plastic film with light-refracting properties on the surface, an...
