Problems solved by technology

[0004] Most of the existing anti-glare glass is produced based on the etching process. This method can indeed greatly improve the light scattering rate, but this method has several obvious defects: ① The concave-convex area produced by etching on the glass substrate will Reduce the overall strength of the glass substrate; ②Increase the light scattering rate and reduce the light transmittance at the same time, that is, the anti-glare and light transmittance cannot be combined; ③The hydrofluoric acid used in the etching process will pollute the environment. cost for the price
[0005] In addition, the anti-reflection and anti-glare film that has emerged in recent years tends to replace the chemical etching process. At present, it is mainly concentrated on the particle film. ", which also affects the user's sensory experience

Abstract

The invention provides a preparation method of an anti-dazzle porous composite film. The preparation method comprises the following steps: (1) preparing silicate sol containing the following components at a mole ratio, wherein the mole ratio of Na2O to Al2O3 to SiO2 is (0 to 0.03): (0 to 0.03): 1; (2) adding a pore forming agent into the silicate sol, enabling the pore forming agent to suspend on the surface of the silicate sol, obtaining a macropore array silicate film compounded with the pore forming agent through a self-assembling reaction, and aging after film formation to obtain a silicate-microparticle composite film; and (3) taking the silicate-microparticle composite film on a slide, carrying out drying and calcinations in sequence, and removing a microparticle template to obtain the anti-dazzle porous composite film, wherein array holes with the pore diameters of 150 to 300 nm are formed in the anti-dazzle porous composite film. According to the prepared composite film, the haze can be improved to the maximum extent on the premise of not reducing the light transmittance in the using process on the glass substrate, so that an anti-dazzle effect is achieved effectively.

Description

technical field [0001] The invention belongs to the technical field of porous membrane materials, and in particular relates to a preparation method of an antiglare porous composite membrane and an antiglare glass using the composite membrane. Background technique [0002] With the development of electronics industry and IT industry, people's demand for in-vehicle multimedia is gradually strong, and the application and market of in-vehicle touch screen modules are expanding day by day. The existing vehicle-mounted touch screens are prone to "dazzling" when exposed to sunlight; when the intensity of ambient light radiation is high and the intensity of the internal light source of the display is low, the user will be affected by the external light from the display. The interference of specular reflected light leads to reduced visibility and even unreadability, anti-glare glass came into being in this context. Anti-glare glass is to process one or both sides of the glass to mak...
