2) suitable quantity of water dissolution is added in the glycerine of recipe quantity, glucolactone；
3) mixed liquor of step 2) is slowly added into the mixed liquor of step 1) under agitation and is uniformly mixed.
Under study for action we have found that the nitration mixture formed using the hydrochloric acid, sulfuric acid and hydrofluoric acid of proper proportion, and is added suitable
When the ammonium fluoride, aluminium chloride and zinc chloride of ratio, suitable glycerine and glucolactone are added, obtained etching solution energy
It is enough while carrying out thinning processing, in the suitable mist degree of glass substrate table surface production, to realize antiglare effect.Locating
It was found that each ingredient in thinning etching process plays synergistic effect in above-mentioned prescription when side's screening, change prescription be will lead to
It is unable to get the anti-dazzle glas of high-transmittance.
Specific embodiment
TFT glass substrate thinning etching solution provided by the invention, is prepared in the following manner,
1) recipe quantity hydrochloric acid, sulfuric acid and hydrofluoric acid are mixed, be added suitable quantity of water dilution after, be added recipe quantity ammonium fluoride,
Zinc chloride and aluminium chloride dissolution,
2) suitable quantity of water dissolution is added in the glycerine of recipe quantity, glucolactone；
3) mixed liquor of step 2) is slowly added into the mixed liquor of step 1) under agitation and is uniformly mixed.
The formula of embodiment and comparative example see the table below
The method for carrying out thin processingization to the etching liquor that embodiment and comparative example obtain is as follows
Taking raw material is glass substrate of the identical producer of plate nitre NA35 with batch, with a thickness of 1.000mm, having a size of
100mm×100mm。
Etch process is
1) thinning of TFT glass substrate is prepared with etching solution 10L (hereinafter referred to as etching solution)
