Description
Technical Field
The invention relates to the technical field of glass surface treatment, in particular to high-alumina glass frosting powder and a using method thereof.
Background
The glass has the unique advantages of good transparency, high mechanical strength, uniform texture, smooth surface and the like, and is widely applied to the industries of buildings, decorations, instruments, daily necessities, electronics and the like. The glass is applied to the electronic industries such as televisions, computers, mobile phones and the like in a super large scale, and an industrial production system of related industries is formed. However, due to the imperfection of glass product manufacture, high intensity light pollution is caused, so that the electronic product poses a threat to the eyesight health of people. Therefore, how to eliminate the problem of light pollution of glass products has become a hot spot of research in the international scientific community. At present, the method of glass frosting is generally adopted to increase the roughness of the glass surface, thereby reducing the light pollution. Glass frosting is a method for deep processing of glass, and particularly relates to a method for processing the surface of glass by using a solution prepared from glass frosting powder.
High alumina glass means Al2O3The glass with the content of more than 12 percent has the advantages of high hardness, good chemical stability, high mechanical strength, high pressure resistance, high temperature resistance, low thermal conductivity and the like, and is applied to the electronic industry on a large scale. However, the frosting powder in the prior art is mainly designed for common soda-lime glass, has poor etching stability for high-alumina glass and low production yield, and particularly cannot meet the precision requirement of high-alumina glass in the electronic industry on surface roughness.
For example, CN104724939A discloses an anti-glare frosting powder for windshields, which comprises the following specific components: ammonium fluoride 14.5%, ammonium bifluoride 14.5%, magnesium hydrogen fluoride 13.5%, and aluminum hydrogen fluoride 13.5% as the main raw material, oxalic acid 3.5%, sodium acetate 2.5%, sodium silicate 2.5%, ammonium fluoroborate 2.5% and sodium fluoroborate 2% as ionic strength regulator, Al2O314% and SiO214 percent of sodium dodecyl sulfate as a viscosity regulator, 1 percent of cellulose MCC1 percent, 0.5 percent of sodium hexametaphosphate and 0.5 percent of sodium polyacrylate as a surfactant. The content of solid acid in the frosting powder is low, the etching performance of the high-alumina glass is poor, the production quantity rate is low, and the precision requirement of the high-alumina glass on the surface roughness in the electronic industry cannot be met.
CN1400184A discloses a preparation method of an environment-friendly type bulb inner shell frosting liquid, and the frosting powder comprises the following specific components: 30-60 parts of ammonium bifluoride, 5-30 parts of fluoride, 5-30 parts of fluorosilicate, 5-30 parts of fluoborate, 1-10 parts of guar gum, 1-10 parts of organic acid, 1-10 parts of barium salt and 2-15 parts of a high-molecular polysaccharide compound; mixing and reacting the frosting powder and industrial hydrochloric acid according to the ratio of 1:0.1-2, and then using the obtained frosting liquid for frosting operation. The content of solid acid in the frosting powder is low, so that industrial hydrochloric acid is needed for curing before use, the frosting powder has the problems of corrosivity, safety, environmental protection and the like, and cannot be suitable for high-alumina glass and meet the precision requirement of the high-alumina glass in the electronic industry on surface roughness.
For the characteristics of high-alumina glass, some researchers improve the acidity of the frosting solution by directly adding hydrofluoric acid and enhance the etching performance, for example, CN110563341A discloses a high-alumina glass frosting solution, which comprises the following components in parts by weight: 30-45 parts of ammonium bifluoride, 5-15 parts of citric acid, 2-5 parts of barium sulfate, 4-10 parts of starch, 2-6 parts of bentonite, 10-20 parts of ferric trichloride, 5-15 parts of potassium fluoride, 6-13 parts of potassium nitrate, 2-6 parts of hydrofluoric acid and 10-30 parts of water. The frosting solution is added with hydrofluoric acid and citric acid at the same time, so that high-alumina glass can be effectively etched, but the problems of too high etching rate and difficulty in control are solved, and the problems of corrosivity, safety, environmental friendliness and the like are solved.
In view of the above, there is a need to develop an effective frosting powder for high alumina glass and a method for using the same.

In order to achieve the purpose, the invention adopts the following technical scheme:
one purpose of the invention is to provide high-alumina glass frosting powder, which comprises the following components in percentage by mass:
in the high-aluminum frosting powder, ammonium fluoride and potassium bifluoride are used as a fluorine ion etching agent to provide water-soluble fluorine ions; sulfamic acid is used as an acidity regulator, can provide hydrogen ions, has the function of acidity regulation, and can generate hydrofluoric acid with fluoride ions for the etching reaction of the high-alumina glass; the precipitated barium sulfate is used as a filling agent, the starch is used as a dispersing agent, and the carboxymethyl cellulose is used as a thickening agent, so that the frosting liquid obtained by adding water for curing has proper viscosity and fluidity, and the whole system is uniform and stable; magnesium fluoride, sodium fluosilicate and potassium fluoroaluminate are used as particle sanding agents and are attached to the surface of the high-alumina glass after etching reaction, and then a 'sand layer' is formed on the etched surface through chemical reaction, so that sanding operation is completed.
According to the high-alumina glass frosting powder, sulfamic acid is used as an acidity regulator, so that on one hand, due to good water solubility of sulfamic acid, the frosting powder is favorable for reaching proper acidity in the process of adding water into the frosting powder, and therefore high-alumina glass is effectively etched; on the other hand, compared with the traditional inorganic strong acid, sulfamic acid as solid organic acid can slowly release hydrogen ions, so that the etching reaction is mild, and the problem of uneven etching caused by over-strong local reaction is prevented.
In addition, the mass percentage of sulfamic acid in the high-alumina glass frosting powder is limited to 15-25%, so that the frosting liquid after being aged by adding water has the advantages of appropriate acidity and uniform and stable system, the surface roughness Ra of the high-alumina glass can be controlled to be 0.1-2.0 mu m, and the high-alumina glass frosting powder has wide applicability. If the mass percentage of the sulfamic acid is too high, the sand coating agent on the particles in the system cannot be effectively attached to the surface of the high-alumina glass, and further the chemical reaction for forming a sand layer cannot be completed; if the mass percentage of the sulfamic acid is too low, excessive fluorine ion etching agent can be caused in the frosting liquid obtained by adding water for curing, and further the fluorine ion etching agent is crystallized and separated out, so that the viscosity of the system is increased and even becomes paste, and the problem of frosting leakage is caused on the surface of the high-alumina glass.

The precipitated barium sulfate of the present invention is generally prepared by the following method: mixing a barium sulfide solution and a mirabilite solution after calcium and magnesium removal, reacting at 80 ℃ to generate a precipitate, carrying out suction filtration, washing with water and acid, adjusting the pH value to 5-6, filtering, drying and crushing to obtain precipitated barium sulfate. The precipitated barium sulfate is white amorphous powder in appearance, has a relative density of 4.50(15 ℃), a melting point of 1580 ℃, shows a white color due to a high refractive index (1.63-1.65), has a certain covering power, is almost insoluble in water, ethanol and acid, and is a chemically stable filler.
