For this reason, Chinese Patent No. CN201310542477.8 discloses an environmentally friendly, acid-free and pollution-free scrub powder and its preparation method. The method adopts ball milling, and the resulting mixture is melted at 1000-1350 ° C. After treatment, the scrub powder is finally obtained. This scrub The powder is environmentally friendly and has no acid pollution, which can avoid harm to the human body and the environment. The frosted glass made of the above-mentioned frosting powder can replace the frosted glass produced by acid etching and machining, and can overcome the rough feel of the grinding surface of the current mechanical processing and hydrofluoric acid. The corrosion method has the disadvantage of pollution

Embodiment 1

[0046] see figure 1 , a preparation method of frosted glass, the preparation method is:

[0047] S1: Prepare scrub powder;

[0048] S2: adding a blending agent to the prepared scrub powder to prepare a slurry;

[0049] S3: apply the frosted slurry on the glass substrate with multiple defoaming brushes, and dry;

[0050] S4: Put the dried glass substrate with frosted slurry into a tempering furnace or a roller kiln for firing.

[0051] Multiple defoaming brushes can realize multiple defoaming of the frosted slurry during the coating process, effectively reduce the residual air bubbles in the frosted slurry, increase the density of the coating layer, and thus improve the preparation quality of the frosted glass.

[0052] Scrub powder includes the following components by weight percentage: SiO2: 60%; ZnO: 30%; CaO: 2%; BaO+SrO: 0.1%; B2O3: 8-30%; Al2O3: 0.1-8% ;TiO2: 0.5-8%; ZrO2: 0-5%; Na2O: 5-20%; K2O: 1-10%; Li2O: 0-8%; P2O5: 1-18%, above The scrub powder prepared from ra...

Embodiment 2

[0063] A preparation method of frosted glass, the preparation method comprising:

[0064] S1: Prepare scrub powder;

[0065] S2: Add a blender to the prepared frosting powder to prepare a slurry, then add an appropriate amount of environmentally friendly defoamer according to industry standards, and stir for 10 minutes. Using the environmentally friendly defoamer can eliminate the air bubbles inside the frosting powder slurry, which is convenient for subsequent coating work;

[0066] S3: apply the frosted slurry on the glass substrate with multiple defoaming brushes, and dry;

[0067] S4: Put the dried glass substrate with frosted slurry into a tempering furnace or a roller kiln for firing.

[0068] Scrub powder includes the following components in weight percentage: SiO 2: 45%; ZnO: 15%; CaO: 2%; MgO: 2%; BaO+SrO: 3%; B 2O 3: 8%; Al 2O 3: 0.1 %; TiO 2: 0.5%; ZrO 2: 2%; Na 2O: 5%; K 2O: 1%; Li 2O: 2%;

Embodiment 3

[0070] A preparation method of frosted glass, the preparation method comprising:

[0071] S1: Prepare scrub powder;

[0072] S2: Add a blender to the prepared frosting powder to prepare a slurry, then add an appropriate amount of environmentally friendly defoamer according to industry standards, and stir for 10 minutes. Using the environmentally friendly defoamer can eliminate the air bubbles inside the frosting powder slurry, which is convenient for subsequent coating work;

[0073] S3: apply the frosted slurry on the glass substrate with multiple defoaming brushes, and dry;

[0074] S4: Put the dried glass substrate with frosted slurry into a tempering furnace or a roller kiln for firing.

[0075] Scrub powder includes the following components in weight percentage: SiO 2: 40%; ZnO: 18%; CaO: 2%; MgO: 2%; BaO+SrO: 3%; B 2O 3: 10%; Al 2O 3: 1 %; TiO 2: 5%; ZrO 2: 3%; Na 2O: 5%; K 2O: 1%; Li2O: 4%;

Abstract

The invention discloses a preparation method for frosted glass, and belongs to the field of glass processing. The preparation method for the frosted glass comprises the following steps that S1, frosted powder is proportioned and prepared; S2, a blender is added into the proportioned and prepared frosted powder so as to prepare the pulp; S3, the frosted powder pulp coats a glass base body by usingmultiple defoaming brushes, and drying is performed; and S4, the dried glass base body with the frosted powder pulp is placed into a toughening furnace or a roller kiln to be sintered. The multiple defoaming brushes comprise powder pulp cylinders and brush heads, detachable connecting pieces are connected between the powder pulp cylinders and the brush heads, the pulp cylinders are used for loading the frosted powder pulp, the surface of the glass base body is coated through the brush heads, the detachable connecting pieces are convenient to detach, replace and clean, multiple defoaming can beperformed on the frosted powder pulp in the coating process through the multiple defoaming brushes, residual air bubbles in the frosted powder pulp can be effectively reduced, the density of the coating layer can be improved so that the preparation quality of the frosted glass can be improved.

Description

technical field [0001] The invention relates to the field of glass processing, in particular to a method for preparing frosted glass. Background technique [0002] Frosted glass is also called frosted glass and dark glass. Due to the rough surface, the light produces diffuse reflection, the light transmitted through is soft but not dazzling, and the light is transparent but not see-through, thus forming a translucent fog surface effect with a hazy aesthetic feeling. It is used for indoor partitions, doors and windows, and also for trademarks, handicrafts, decorations, etc. [0003] At present, the processing methods of frosted glass mainly include mechanical processing and hydrofluoric acid corrosion. The disadvantages of mechanical processing methods are large investment, high cost, rough surface feel, and low production efficiency, and it is not easy to process special required patterns. Acid etching and frosting use hydrofluoric acid as the main etchant. For example, in...
