Abstract
The invention discloses an anti-dazzle method for optical glass by a wet process. The method specifically comprises the following steps: cleaning, wind-shearing and drying a to-be-processed fresh glass substrate in a dust-free environment; further cleaning the glass substrate by adopting a plasma gas, and roughening the surface of the glass; pre-heating the substrate and maintaining constant temperature; adjusting parameters of a spraying process; coating an anti-dazzle liquid by way of ultrasonic atomization; placing, leveling and carrying out surface dry after coating; roasting and curing to form a film; and slowly cooling the substrate to room temperature and preparing the anti-dazzle glass after examination. Compared with existing anti-dazzle technology, the hardness is increased from 2H to over 5H compared with that of a straight sticker. Compared with conventional anti-dazzling in an etching method, environment-friendliness is realized and Moore phenomenon is reduced. The cleanness is further enhanced and the film binding force is improved by adopting the plasma gas to roughen the glass substrate. The effect of ultrasonic atomization is better than that of common aerodynamic discretion. The atomizing particles are smaller and more uniformly dispersed.
Description
Technical field
The present invention relates to a kind of glass anti-dazzle method, relate in particular to a kind of opticglass wet method anti-dazzle method.
Background technology
At present, electronic display unit is attracted attention by the client more and more, and range of application also can be more and more extensive.Yet, high-resolution display device is in the situation that sun direct projection and high illumination etc. watch the not good sharpness of condition to be affected, picture meeting metamorphopsic distortion, therefore need to carry out non-glare treated to the display equipment cover-plate glass, make former reflecting surface become the dumb light diffuse reflection surface, reach the purpose that reduces ambient light interference.
On equipment, the straight antiglare film of pasting can achieve the above object, but the pad pasting product hardness is very low.Except pad pasting, anti-dazzle performance obtains by following two kinds of approach substantially: dry process film and wet process film.Dry process film even thickness (deviation is less than 5%), rete densification, but required equipment complexity, film speed is slow, film toughness is poor, and cost is high, therefore few in industrial application.Wet process film be by methods such as spraying, spin coating, dipping lift by the film forming sol coating at substrate surface, after heat treatment obtain.With dry method, compare simple to operationly, and cost is lower and be used widely.In this several wet process film technique, when the spin coating mode prepares large-size glass, glass edge can apply irregular, and size increases again, and the rotation meeting is because gravity factor is subject to larger the impact.The dipping method of pulling up product tighter for film thickness monitoring can't be suitable for;
Increase the roughness of display screen surface.Directly display screen surface carried out to mechanical mill or carry out selectively corroding and making its surface irregularity with the etching reagent of hydrofluoric acid and so on, this method environmental pollution is larger, treated glass screen can not recycling, also destroyed the transparency of display screen, being easier to dust and accumulating, is the main flow of current domestic production.
The spraying method principle that the present invention adopts is to spray one or more silicon ester or silicate solutions is deposited as the film that the rough silicon-dioxide small-particle of one deck forms in display screen surface, thereby around scattering, the reflected light of light source reaches anti-dazzle effect.The method is easy to operate, and antiglare effect is also better, and the glass screen after use is also recyclable, so spraying method prepares the main flow that anti-glare glass will become development in following 5～10 years.
Summary of the invention
Purpose of the present invention just is that providing a kind of addresses the above problem, improve the pollution technique that domestic employing etching obtains antiglare effect, provide that a kind of manufacturing process is simple, cost is low, environmentally friendly, reach the anti-glare glass performance effect identical with lithographic technique be deposited, and reduce the opticglass wet method anti-dazzle method of the generation of mole phenomenon.
To achieve these goals, the technical solution used in the present invention is: a kind of opticglass wet method anti-dazzle method, and the concrete technology step is as follows,

C) by the substrate preheating and keep constant temperature;
D) adjust spraying parameter;
E) substrate, under spraying parameter and constant temperature, adopts the ultrasonic atomizatio mode, carries out the anti-dazzle liquid coating;
F) place levelling and surface drying after the spraying;
G) toasted film-forming;
H) substrate temperature slowly is down to room temperature, completes the making of anti-glare glass after check is without bad defect;
As preferably, in step c, described preheating temperature scope is 0～130 ℃;
As preferably, in steps d, spraying parameter comprises, spray pressure is 1～60psi, and the coating flow is 1～40ml/min, and travelling speed is 20～300mm/s, and spraying is highly 5～50mm;
As preferably, in step e, anti-dazzle liquid is the anti-dazzle coating-forming agent of GLS-AG;
As preferably, in step f, be 3～4min described storage period;
As preferably, adopt three-dimensional circulation drying tunnel to be toasted, storing temperature is 50～500 ℃;
As preferably, anti-dazzle liquid contains two kinds of silica dioxide granules that diameter is different.
Compared with prior art, the invention has the advantages that:
(1) with straight pad pasting, compare, more than hardness has increased to 5H by 2H;
(2) compare with traditional etching method is anti-dazzle, realized environmentally friendly, as to have reduced mole phenomenon generation;
(3) adopt plasma gas to carry out alligatoring to glass substrate, further strengthen cleanliness factor, improve and be coated with binding force of membrane;
(4) ultrasonic atomizatio is than pneumatic discrete better effects if commonly used, and atomizing particle is more tiny, disperses more even.
