Description
Technical field
The present invention relates to chemical industry, nano material, film preparation and clean energy resource field, particularly relate to a kind of nanometer anti-reflection coating liquid and its preparation method and application.
Background technology
Now, transparent material is widely used in industry-by-industry, such as solaode cover-plate glass, optics etc..Owing to refraction index is different, light still can produce reflex at air/material interface when by transparent material, thus can not all pass through, reduces its light transmittance.Such as, glass is most commonly seen transparent material, and the single face reflectance of simple glass is approximately 4%, and therefore its total light transmittance is difficult to more than 92%.Requiring higher system for some transparencys, such as solaode, display screen and optics etc., the visible ray proportion of goods damageds of 8% can largely effect on the energy ecology of equipment.For solaode, if the visible light transmissivity of glass can improve further, the energy conversion efficiency of solaode then can be greatly improved.And for display screen material, the raising of screen glass light transmittance then can reduce the brightness requirement to backboard, thus the power consumption of equipment is greatly reduced, extend the service life of battery.
It is said that in general, by the thin film preparing one or more layers low refractive index at substrate surface, reduce the light reflectance at interface, it is possible to improve the light penetration of material.Still for glass, the refraction index of glass is about 1.5, and Theoretical Calculation draws, if forming one layer of refraction index at glass surface is the thin film of 1.25, then the light transmittance of glass can be brought up to 100%.But the refraction index of the material (Afluon (Asta)) that the refraction index that nature is known is minimum is also only 1.38.Therefore, it is presently mainly by introducing hole at thin layer, utilizes the low refractive index (1.0) of air to reduce the refraction index of thin film.
From technological angle, the preparation method of anti-reflection film mainly includes following several: etching method, vacuum vapour deposition and sol-gel process.Inorganic Substrate Surface layer, generally by the material of severe corrosive, is performed etching by etching method, thus reducing the consistency of glass surface, forms the anti-reflection thin layer of high porosity.CN102674704 and CN102491649 is utilized respectively fluorine-containing strong acid and glass is performed etching the antireflection layer obtaining porous at glass surface by disodium hydrogen phosphate/aluminum chloride mixed liquor.The method has the drawback that flow process is longer, and the etchant adopted is high, not environmentally, has potential safety hazard.Vacuum Coating method includes magnetron sputtering and vapour deposition process etc., and its common feature is under vacuum conditions, the gasification of high-purity target target or ionizing is occurred physics or chemical reaction again, generates thin layer at substrate surface.As CN20244455 make use of magnetron sputtering technique to be prepared for the anti-reflection coating with multi-layer film structure at glass surface.Vacuum Coating method can prepare the antireflection layer that thickness is highly uniform, but process conditions are very harsh, and equipment cost is higher.
Comparatively speaking, the filming equipment of sol-gel process is simple, can operate under normal temperature and pressure conditions, and the Modulatory character of technical recipe is high, therefore applies more extensive.This technique is using the compound containing high chemical active ingredient as presoma, it is mixed to get clear solution with alcohols or ketones solvent, adding appropriate water causes hydrolysis-condensation reaction to obtain transparent colloidal sol, it is coated on substrate surface subsequently, after its drying and forming-film, carry out heat treatment, then can obtain inorganic anti-reflection film.The Main Function of follow-up heat treatment process is to be sintered the gel layer formed in drying and forming-film process solidifying to obtain the antireflection layer containing hole.The preparation method that namely CN103524049 discloses a kind of monolayer antireflecting silicon dioxide film.Silicon dioxide organic precursor is first dissolved in acid alcohol/water mixed liquid by the method, subsequently until it after substrate glass surface filming, is thermally treated resulting in monolayer silicon dioxide plated film then through 200～400 DEG C.And for example CN102850894 is first prepared for the complex sol that size is different, then itself and coalescents are blended in substrate surface prepare anti-reflection coating.Although this method is simple, but the storage stability that the shortcoming affecting its large-scale industrial application is colloidal sol is poor, because most of colloidal sols are thermodynamically in metastable state, thus causing that it can produce flocculation or sedimentation after storage certain time due to uncontrollable hydrolysis-condensation reaction.
If therefore anti-reflection film coating liquid can be prepared from stable nano-particle, then can be greatly improved the stability of technique and product.But currently without the anti-reflection film preparation method based on nano-particle of comparative maturity, be primarily due to compared to sol-gel process, prepare coating liquid from granule directness, the requirement of coating liquid formula and technique is higher.Although CN102795791 is prepared for anti-reflection film with nanometer silicon dioxide particle for raw material, but the LBL self-assembly technique of the electrostatic attraction effect that is based on adopted.This technological process is complicated, simultaneously to the utilization ratio of raw material extremely low (several times of the grain amount that grain amount is actual participation film forming lost in actual process process or even decades of times), so not utilizing extensive commercial application.Additionally, membrana granulosa needs other problem solved is that between rete and base material, adhesive force is inadequate when application, this leverages its service life.
Summary of the invention
The technical problem to be solved is in that defects such as overcoming existing thin film fabrication techniques route complex process, relatively costly, service life is short, it is provided that a kind of nanometer anti-reflection coating liquid, and the transparent base being coated with anti-reflection film prepared by it.
