Referring to fig. 1, the present embodiment provides a full-lamination method for an AG anti-glare live broadcast touch screen, including the following steps:
s1, performing AG anti-glare treatment on glass to obtain AG anti-glare glass.
The glass is pre-washed by adopting a pre-washing liquid medicine, and is placed into a frosting liquid medicine of a frosting device for frosting treatment after pre-washing, so that the working surface of the glass forms a microscopic pit shape, and then polishing treatment is carried out by adopting a polishing liquid to achieve the effects of transparence and AG anti-dizziness.
AG anti-glare treatment, namely etching AG, dissolving silica on the surface layer of the glass by hydrofluoric acid, and obtaining a glossy surface or a matt rough surface according to different solubilities of residual salts. The basic principle of etching is that the silicon oxide layer on the surface of the glass and the radon-fluoric acid or its salts are chemically reacted, and the crystal structure on the surface of the glass is made to be in an uneven state through the erosion reaction on the surface of the glass, so that the light is refracted and scattered, and the glass becomes an opaque and lusterless frosted surface according to the difference of the solubility of the residual salts after the acid etching. The chemical reaction is simply shown as follows:
＝Si-O-Si＝+R+F→＝Si-OR+＝Si-F；
in the formula, R is H + 、Na + 、K+、NH + 、Ca 2+ For convenience of description, R is represented by H + hereinafter. Si in a silicon oxide layer 4+ And O 2- Meanwhile, the electric energy is continuously attacked by new positive and negative charges, so that mutual chemical reaction is easy to occur;
product = Si-OH in the above formula may also continue to react with hydrofluoric acid to form fluorosilicic acid, e.g.
Si(OH) 4 +6HF＝＝HSiF+4H 2 O；
Reacting soda-lime glass with hydrofluoric acid: under the general condition, it is in gas state, but it is not volatilized in time in the solution, and it reacts with water and hydrofluoric acid to produce complex fluosilicic acid.
3SiF 4 +3H 2 O＝＝H 2 SiO 3 +2H 2 SiF 6 ；
SiF 4 +2HF＝＝H 2 SiF 6 ；
In addition, hydroxide generated by silicate hydrolysis in the glass and fluosilicic acid can react with each other to obtain fluosilicate, and the reaction formula is shown as a series of reaction formulas:
Na 2 SiO 3 +2H 2 O＝＝2NaOH+H 2 SiO 3 ；
H 2 SiF 6 +2NaOH＝＝Na 2 SiF 6 +2H 2 O；
CaSiO 3 +2NaOH＝＝Ca(OH) 2 +NaSiO 3 ；
2H 2 SiF 6 +Ca(OH) 2 ＝＝CaSiF 6 +H 2 SiO 3 +H 2 O；
if the frosting agent or frosting paste contains fluoride, the fluoride will also react with SF 4 Producing fluorosilicate with the following reaction formula:
2NH 4 F+SiF 4 ＝＝(NH4)SiF 6 ；
2NaF+SiF 4 ＝＝Na 2 SiF 6 ；
CaF 2 +SiF 4 ＝＝Ca 2 SiF 6 ；
there are two main classes of reactant salts:
(1) Fluoride: is easy to dissolve in water: alkali metal fluorides such as potassium and sodium; water-insoluble: calcium fluoride, barium fluoride and lead fluoride.
(2) Fluorosilicate: the solubility in water is small: fluorosilicates of potassium, sodium, calcium, barium, lead; high solubility in water: ammonium fluorosilicate.
In the formulation of the frosting agent, some salts which are expected to generate low solubility, such as calcium fluoride and barium, can be added according to requirements. Lead salt and potassium, sodium, calcium and barium fluosilicate are crystallized on the surface of glass to form initial crystal nucleus and grow continuously. The part of the glass surface covered by the crystalline salt prevents the contact and further reaction with the frosting agent; while the portions of the glass surface that are slightly covered, i.e., the gaps between the crystallized grains, remain exposed to the frosting agent and are eroded. Salt crystallization at the covering part is changed continuously, and glass at the gap covered by the covering part is eroded continuously, namely the surface of the glass surface is eroded unevenly to form an uneven matt surface.
