After the above-mentioned protection liquid preparing one side toughened glass is coated in glass surface formation protective membrane; because protective membrane has good viscosity; be not easy to come off from glass surface; can not produce fused salt and pollute; after forming one side toughened glass; because protective membrane is soluble in water, easily that protective membrane is clean from one side toughened glass surface cleaning, be not easy to produce residual on one side toughened glass surface.
Introduce the above-mentioned protection liquid preparing one side toughened glass below and prepare the application in one side toughened glass.
As shown in Figure 1, the preparation method of the one side toughened glass of an embodiment, comprises the steps:
S10, provide pending glass.
Pending glass can be ultra-thin glass or sheet glass.The thickness of ultra-thin glass can be 0.2mm ~ 1.1mm.The surface of pending glass can deposit one deck conductive layer.The material of conductive layer can be tin indium oxide (IndiumTinOxides, ITO) etc.Before painting protection liquid, first glass is carried out cleaning and drying.
S20, form protective membrane in surface-coated layer of protecting liquid of glass.
In the present embodiment, protect liquid to comprise each component of following mass percentage: the metasilicic acid of 0.7% ~ 42% and the mixture of two silicic acid, 0.1% ~ 48% disilicic acid, 0.1% ~ 5% water soluble alkali, the acetone of 0.5% ~ 30%, the ethanol of 0.5% ~ 40% and surplus water.Wherein, in the mixture of metasilicic acid and two silicic acid, the mass ratio of metasilicic acid and two silicic acid can be 1:1 ~ 10, in actual applications, can regulate the mass ratio of metasilicic acid and two silicic acid as required.In the present embodiment, water soluble alkali is sodium hydroxide.In other embodiments, water soluble alkali can also be potassium hydroxide, sodium carbonate or sodium bicarbonate.
In one embodiment, protect liquid to comprise each component of following mass percentage: the metasilicic acid of 0.9% ~ 15% and the mixture of two silicic acid, 0.9% ~ 15% disilicic acid, 0.1% ~ 3% water soluble alkali, the acetone of 18% ~ 30%, the ethanol of 15% ~ 30% and surplus water.
In a preferred embodiment, protect liquid to comprise each component of following mass percentage: the metasilicic acid of 0.9% and the mixture of two silicic acid, 0.3% disilicic acid, 0.1% water soluble alkali, the acetone of 5%, the ethanol of 18% and surplus water.Now, the reaction of metasilicic acid, two silicic acid, disilicic acid and sodium hydroxide is comparatively complete, and the viscosity of the protection liquid obtained is better.
In the present embodiment, roller painting can be adopted to form protective membrane in a surface-coated layer of protecting liquid of glass.The quality of protective membrane adopting roller painting coating to be formed is good, homogeneous, and roller painting to have working efficiency high, the advantages such as environmental pollution is little.Certainly, in other embodiments, additive method can also be adopted to form protective membrane in a surface-coated layer of protecting liquid of glass.
In the present embodiment, the thickness of the protective membrane of formation can be 3 μm ~ 8 μm.
S30, glass preheating 15 ~ 100 minutes under 270 DEG C ~ 370 DEG C conditions that will protective membrane be coated with.
In one embodiment, glass preheating 30 minutes under 350 DEG C of conditions that can will be coated with protective membrane.The glass being coated with protective membrane is carried out preheating to be cured protective membrane.
S40, the glass after preheating put into the fused salt reaction 3 ~ 8 hours of 390 DEG C ~ 440 DEG C.
In the present embodiment, fused salt can be saltpetre fused salt.In other embodiments, according to the character of the one side toughened glass that will prepare, in fused salt, appropriate potassium hydroxide and aluminium sesquioxide etc. can also be added.Glass after preheating is put into the fused salt of 390 DEG C ~ 440 DEG C, do not have the potassium ion in the metal ion on the surface of the glass of coating protective film and fused salt to carry out ion-exchange.Utilize the difference on basic ion volume to form embedded squeezing stress on the top layer of glass, form compressive stress layer on the surface of glass, thus reduce the impact of glass surface crackle, improve the intensity of glasswork.
S50, reacted glass is carried out anneal, obtain one side toughened glass.
After glass carries out ion exchange reaction, slowly taken out by glass from fused salt, the annealing furnace putting into temperature identical or close with temperature of molten salt is annealed to room temperature.
The preparation method of above-mentioned one side toughened glass; after a surface-coated protection liquid of pending glass forms protective membrane; protective membrane can prevent the surface of the glass being coated with protective membrane from the fused salt of high temperature, carrying out ion-exchange; ion exchange reaction can only be carried out on the surface of the glass of uncoated protective membrane, thus obtains one side toughened glass.The preparation method of above-mentioned one side toughened glass only needs can enter protection at a surface-coated layer protecting film of glass, does not need to carry out ion exchange reaction in the effect of extra electric field, lower to equipment requirements.Meanwhile, this preparation method is simple to operate, is easy to realize.
