Problems solved by technology

However, when spherical sol particles are used to form a film: if the bonding between the particles is weak, it is conducive to the formation of a porous structure, which can reduce the refractive index to 1.2, but the strength is poor and not wear-resistant; if the bonding between the particles is strong, Although the mechanical properties and wear resistance can be greatly improved, the porous structure is greatly sacrificed, the refractive index of the film layer is relatively high, and the anti-reflection effect is not good.

Abstract

The invention discloses a POSS (Polysilsesquioxane)-containing antireflective film coating liquid and a preparation method and application thereof, and belongs to the field of film coating liquids. The preparation method of the POSS-containing antireflective film coating liquid comprises the following steps of: adding the following raw materials in percentage by weight: 0.01%-20% of POSS derivatives, 0-10% of nanometer silicon dioxide granules, 0%-10% of hollow silicon dioxide, 0%-5% of non-silicon nanometer oxide granules, 0%-10% of organic silicon compounds, 0%-50% of deionized water and 0%-2% of catalysts into a solvent; and reacting at 20-150 DEG C for 0-45 hours to obtain the POSS-containing antireflective film coating liquid. The POSS-containing antireflective film coating liquid disclosed by the invention can be applied to photovoltaic glass, display screen base plate glass, building glass and automobile glass; and the obtained antireflective film has the advantages of good film layer uniformity, high adhesive force and rigidity and good weather resistance.

Description

[0001] technical field [0002] The invention relates to the field of coating solution, in particular to a coating solution containing POSS anti-reflection film and its preparation method and application. Background technique [0003] Incident light (intensity of I 入射 ) passing through a medium, it will reflect a part of the light on the surface of the medium (the intensity is I 反射 ), through which a portion of the light (with an intensity of I 透过 ), and the medium absorbs a portion of the light (intensity of I 吸收 ) in, then: [0004] I 入射 = I 反射 + I 透过 + I 吸收 . [0005] In many cases, the reflected light when light passes through some media can have a great impact on the application, such as: [0006] (1) Solar cell field [0007] As an inexhaustible clean energy source, solar energy has been paid more and more attention by people. The effective use of solar energy can not only alleviate the problem of energy shortage to a large extent, but also ca...
