Example Embodiment

[0055] Example 1

[0056] (1) Disperse 4.625Kg of nano-silica with a particle size of 5nm in 87.875Kg of deionized water to prepare a 5% dispersion, and add 2.775Kg of ethanol to the dispersion to prepare a 5% mass percentage concentration. The 3-(methacryloyloxy)propyltrimethoxysilane solution is heated to 70°C with stirring, and the reaction is maintained at this temperature for 30 minutes;

[0057] (2) Add 2.9193Kg ethanol, 23.7513Kg deionized water, 1.190Kg acrylic acid, 0.158Kg methacrylic acid, 0.06625Kg ethylene glycol dimethacrylate to the solution of step (1) under stirring. The mixed solution was stirred and mixed at 70°C for 40 minutes, then 0.09225Kg potassium persulfate was added, and reacted for 8 hours in a sealed reaction device. After cooling, a core-shell structure spherical acrylic acid and difunctional methacrylate copolymer with a particle size of 35nm was obtained -Silica colloidal nanocomposite material light blue dispersion;

Abstract

The invention discloses a preparation method of an antifogging and antireflection film coating liquid. The preparation method comprises the following steps: (1) dispersing nano silica in deionized water to prepare a dispersion liquid with mass percent concentration of 0.1-30%, adding a silane coupling agent to the dispersion liquid, heating to raise the temperature, and reacting for 0.2-1 hour; (2) adding a mixed solution which is formed by acrylic acids and acrylic esters and is diluted by a diluent to the solution in the step (1), stirring and mixing the solutions at 50-80 DEG C for 30-40 minutes, then adding an initiator, reacting for 5-10 hours, and cooling to obtain a nanocomposite dispersion liquid; (3) diluting the nanocomposite dispersion liquid in the step (2) into a solution with concentration of 0.1-50wt%. The preparation method has the beneficial effects that an in-situ free radical polymerization method is adopted, the coating effects are better, the coating can be ensured to have good apparent properties, and the coating is high in drying speed and has excellent antireflection and anti-dazzle effects.

Description

technical field [0001] The invention relates to the field of film materials, in particular to a method for manufacturing an anti-fog and anti-reflection film coating solution. Background technique [0002] In the case of sufficient water vapor, low wind force and stable atmosphere, if the air close to the ground is cooled to a certain extent, the water vapor in the air will condense into fine water droplets suspended in the air, reducing the visibility at the ground level. Known as fog, in autumn and winter, foggy days appear frequently. Fog is very harmful. In this weather, a layer of fog often appears on glass surfaces such as automobile glass and bathroom mirrors, which affects normal use. For example, if the windshield of a car is foggy, it will affect driving safety and even bring life danger. People who wear myopia glasses in winter often encounter the situation that a layer of fog occurs on the glasses when entering the warm room, which brings great inconvenience to ...
