Abstract
The invention provides a TiO2-PS core-shell structure nano powder used in optical glass coating comprising the following steps: dipping TiO2-PS core-shell structure nano powder by a flexible material to wipe the surface of the hairy or smooth optical glass till the surface of the optical glass is coated with a TiO2 film; or adding 2g-10g of TiO2-PS core-shell nano powder into 20ml-50ml of deionized water or anhydrous alcohol, uniformly mixing and preparing a TiO2-PS core-shell nano powder suspending liquid, directly coating the TiO2-PS core-shell nano powder suspending liquid on the hairy or smooth optical glass surface, wiping the glass with the flexible material after heat drying or air drying till the surface is coated with a TiO2 film. The method of the invention coats the TiO2-PS core-shell nano powder on the optical glass surface by a frictional coating method, which has anti reflection function of the visible light zone, furthermore effectively filters the ultraviolet ray under 400nm, and enables the film coating cost to reduce and the time to shorten with good effect.
Description
Technical field
The present invention relates to a kind of TiO
2Rub on the opticglass application of plated film of-PS (titanium dioxide-polystyrene) core-shell structure nanopowder belongs to TiO
2The applied technical field of-PS core-shell structure nanopowder.
Background technology
As everyone knows, no matter is the glasses that people wear now, or the vehicle window of automobile all is coated with anti-reflection usually and have the film of anti-ultraviolet function.Carry out the method that plated films such as anti-reflection film, filter ultraviolet ray are generally taked the high temperature high vacuum at opticglass and crystalline material surface, such as particle beam magnetron sputtering, chemical vapor deposition (CVD), molecular beam epitaxy (MBE), laser molecular beam epitaxy, pulsed laser deposition etc., this all needs accurate expensive plant and instrument and valuable target material or reaction source material.
Existing glass coating technology has on-line coating and method such as off-line coated.On-line coating has another name called hard plated film, be with process for chemical vapor deposition of materials with via (CVD), at float glass process cold junction deposit film on float glass, therefore name with " online ", its advantage be can deposit, the rete adhesivity is good, be fit to produce in enormous quantities, shortcoming is that simple products, kind are single, color is dull, switching cycle is long between the different varieties, can't in time make a response according to client's needs.And off-line coatedly have another name called soft plated film, be to utilize magnetron sputtering, physical vapor deposition (PVD) that material surface is carried out evaporation, its advantage be kind color selectivity wide, can in time change kind.On-line coating and off-line coated both are a kind of complementary relationship.Plated film lens is to add the multiwalled antireflective coating at lens surface, to reduce specular reflection, increases transmittance, guarantees that vision is clear, increases aesthetic feeling, and reduces infrared rays and ultraviolet damage to eyes.
Titanium dioxide (TiO
2) be a kind of semiconductor material with wide forbidden band, except in photochemical catalysis, being widely used TiO
2Film is because of having high photoelectric response, ultraviolet ray filtering, have from cleaning and hydrophobicity, having advantage such as the antifog and wear resistance of anti-soil and extensively be applied in the plated film of eyeglass, glass for vehicle window as Coating Materials.Can realize anti-reflection, the beam split, optical filtering of glass, high function such as anti-by plated film.
The antiultraviolet film on the glasses or the anti-reflection film of opticinstrument etc. generally all can wear and tear or loss after use after a while to some extent.There is the scared phenomenon such as fog of eyeglass especially in common resin glasses.And if utilize conventional film coating method that eyeglass is safeguarded, not only very expensive consuming time but also long, be unpractical.Eliminating of therefore a lot of glasses is not because the number of degrees are improper because the wearing and tearing of eyeglass have so just caused great waste.Therefore how fast, impaired glasses film and other glass films of low-cost reparation is a very significant research work.
TiO
2-PS core-shell structure nanopowder is introduced in the preparation process of three-D photon crystal, generally is preparation TiO
2After-PS the bead, utilize slowly again to deposit to obtain the TiO of periodic arrangement
2-PS photonic crystal obtains counter opal structure (TiO thereby with the method for slow oxidation the PS bead is removed then
2The parcel air).Recently about TiO
2The attriting performance of-PS nano powder has report to think TiO
2-PS bead attriting performance has wear resistance and oilness preferably.TiO
2-PS core-shell structure nanopowder does not also carry out the report that plated film is used on opticglass.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of TiO is provided
2The application of-PS core-shell structure nanopowder on optical glass coating makes the coating cost of opticglass low, the time is short, effective.
TiO of the present invention
2The application of-PS core-shell structure nanopowder on optical glass coating is to utilize flexible materials to dip in to get TiO
