Embodiment 1

[0040] After adding 55 ml of distilled water to 45 ml of a 10% by weight solution of silica gel (Ace Hitech, Silifog) with an average particle size of 6 nm, it was treated with an ultrasonic homogenizer for about 30 minutes, thereby producing a silicon oxide dispersion with a concentration of 4.5% by weight. Add 0.14 g of NH to the dispersion 4 F, make [NH 4 F] / [SiO 2 ] at a molar ratio of 0.05 and treated with an ultrasonic homogenizer for about 30 minutes, thereby preparing a coating composition. In order to observe the pH and particle size of silicon oxide particles, after manufacturing part of the coating composition, the solution was measured with a Ph measuring instrument (Hanna HI221) and a particle size analyzer manufactured by Malvern Instrument Co., Ltd. (Malvern) for 15 days. pH and particle size of silica particles.

Embodiment 2 to 4

[0046] In addition to using 0.27g, 0.55g and 1.11g of NH 4 Except F, the implementation method of embodiment 2 to 4 is the same as the method of embodiment 1. If gelation or particle size reduction of nano-silica particles occurred within 12 hours after the coating composition was manufactured, coating was not performed. Table 1 shows the measured physical properties.

Embodiment 5 to 8

[0048] In addition to using 0.08g (equivalent to 0.007 mole ratio), 0.18g, 0.35g and 0.72g (equivalent to 0.066 mole) H 2 SiF 6 to replace NH 4 Except F, the implementation method of embodiment 5 to 8 is identical with the method of embodiment 1. If gelation or particle size reduction of nano-silica particles occurred within 12 hours after the coating composition was manufactured, coating was not performed. Table 1 shows the measured physical properties.

Abstract

The present invention provides a method for preparing a glass substrate with antireflection functionality by applying a coating formulation that affords antireflection effects to a substrate comprising water, metalloid oxide nanoparticles that are dispersed in said water, and a hydroxide ion agent or fluoride ion agent that is introduced into said metalloid oxide nanoparticles at a mole ratio of 0.005-2:1. The coating formulation of the present invention enables manufacture of a porous nano antireflection film with high transmission following a more streamlined process than the prior art, obtaining an antireflection film with a high adhesive force between the film and substrate, and high durability by increasing particle-particle bonding and the bond strength between particles and substrate.

Description

technical field [0001] The invention relates to a coating composition for imparting anti-reflection effect to a transparent base material and a method for preparing a transparent base material with anti-reflection function by using the coating composition. Background technique [0002] When watching TV in a bright environment, due to the reflectivity of the glass or optical resin used in the manufacture of monitors or glasses, it cannot provide 100% light transmittance, and it is often difficult for people to see the content displayed on the screen. A phenomenon in which the screen cannot be viewed well. Therefore, in order to maintain the image resolution of the optically transparent substrate, anti-reflection technology (AR) is often used to treat the surface of the transparent substrate to reduce the reflectivity and increase the light transmittance. This AR technology can be widely applied to optical devices such as telescopes, glasses, optical communication parts, phot...
