Description

Technical Field

[0001] The invention relates to the technical field of C03C15 / 00, and in particular to a water-based glass frosting powder and a preparation method and application thereof. Background Art

[0002] A Chinese patent with patent application number CN202110125166.6 discloses an anti-glare glass water-based frosting powder and its application in the anti-glare glass frosting processing. It uses ammonium bifluoride and organic acid to solve the problem of easy transportation of frosting powder for processing anti-glare glass; however, the technical problems of increasing the processing volume of glass and producing high roughness through processing have not been disclosed.

[0003] The frosting powder currently on the market can only process a few thousand pieces of glass at a time, and the surface of the glass cannot be highly rough after processing, which affects the touch of the glass.

[0004] Therefore, providing a product that can process more glass and produce high roughness on the glass surface is the main technical problem that needs to be solved at present. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a water-based glass frosting powder. The raw materials for preparation include, by weight, 45-55 parts of fluoride, 18-22 parts of treating agent, 2-8 parts of dispersant, 1-5 parts of antifreeze agent, and 5-10 parts of filler.

[0006] Preferably, the antifreeze agent is ethanol or ethylene glycol.

[0007] Preferably, the treatment agent is an organic acid or an inorganic substance; the organic acid is selected from one or more of methanesulfonic acid, citric acid, oxalic acid, and salicylic acid.

[0008] The inorganic substance is selected from one or more of ammonium persulfate, sodium persulfate and potassium persulfate.

[0009] The methanesulfonic acid was purchased from Guangzhou Ninghe Chemical Co., Ltd. and the model number was Arkema MAS-high alcohol methanesulfonic acid.

[0010] Preferably, the fluoride is selected from one or more of ammonium fluoride, calcium fluoride, sodium bifluoride, potassium bifluoride, and potassium fluoroborate.

[0011] Preferably, the fluoride is ammonium fluoride.

[0012] Preferably, the dispersant is a surfactant.

[0013] Preferably, the surfactant is selected from one or more of sodium alkyl sulfonate, hydroxycellulose and sodium lignin sulfonate.

[0014] The weight ratio of the dispersant to the fluoride is 1:(10-15).

[0015] Preferably, the sodium alkyl sulfonate is selected from one or more of sodium dodecylbenzene sulfonate, sodium dodecyl sulfonate, sodium tridecylbenzene sulfonate and sodium hexadecylbenzene sulfonate.

[0016] Preferably, the sodium alkyl sulfonate is sodium dodecyl sulfonate.

[0017] Preferably, the filler is selected from one or more of bentonite, kaolin and titanium dioxide.

[0018] Preferably, the filler has a particle size of 1000-5000 mesh.

[0019] Preferably, the filler is kaolin.

[0020] The particle size of the kaolin is 4000 mesh, and the kaolin is purchased from Lingshou County Chengnuo Mineral Products Co., Ltd.

[0021] In order to improve the environmental friendliness of water-based glass frosting powder during application and improve the treatment performance of glass surface roughness, the applicant unexpectedly found in the experiment that when the treatment agent is mixed with fluoride, dispersant, antifreeze agent and filler, especially when the treatment agent is an organic acid or an inorganic substance, the organic acid is selected as methanesulfonic acid, and the inorganic substance is selected as sodium persulfate, the performance of water-based glass frosting powder in treating glass can be improved. The possible reason is that when methanesulfonic acid or sodium persulfate is used in combination with sodium dodecyl sulfonate, especially when the weight ratio of sodium dodecyl sulfonate to ammonium fluoride is 1: (10-15), the dispersibility of kaolin in the system can be improved, thereby improving the dispersion uniformity of each raw material in the raw material system, thereby improving the formation of a high roughness surface on the glass surface when the water-based glass frosting powder is added to water to treat the glass, thereby improving the treatment effect of the glass surface. At the same time, because methanesulfonic acid is added to the water solution, after the glass is treated, the obtained product has a certain wetting property, will not reduce the cleaning intensity, and improves the number of times the water-based glass frosting powder can be used.

[0022] The second aspect of the present invention provides a method for preparing water-based glass frosting powder, comprising the following steps: mixing and stirring ammonium fluoride, an organic acid, a dispersant, an antifreeze agent, and a filler, and grinding to obtain the water-based glass frosting powder.

[0023] When the treating agent used in the present application is an organic acid, the water-based glass frosting powder prepared by using methanesulfonic acid will not cause serious corrosion to the surface of the storage material when used, and is convenient for storage and transportation of the water-based glass frosting powder.

[0024] A third aspect of the present invention provides an application of water-based glass frosting powder in the field of glass processing technology, comprising the following steps:

[0025] S1. The aqueous glass frosting powder is added to water and stirred to obtain a frosting liquid;

[0026] S2. Treat the stains on the glass surface to form clean glass;

[0027] S3. Immerse the clean glass in the frosting solution for a period of time and then take it out;

[0028] S4. The glass is washed with water, polished and dried to obtain a finished product.

[0029] The weight ratio of the water-based glass frosting powder to water in S1 is 1:0.2-0.8.

[0030] Beneficial Effects

[0031] The frosting powder provided by the invention can etch a glass surface with high roughness, and the roughness Ra thereof is higher than 1000nm. The prepared glass surface has a delicate and smooth feel and a more comfortable touch.

[0032] When the frosting powder provided by the invention is added into water for glass treatment, the treatment amount can reach more than 10,000 pieces.

[0033] The frosting powder provided by the invention does not use strong acid, which can not only prevent workers from being hurt, but also protect the environment.

[0034] The frosting powder provided by the invention uses methyl sulfonic acid as the organic acid, which will not cause serious corrosion to the surface of the storage material during use, and is convenient for storage and transportation of the water-based glass frosting powder.

[0035] The frosting powder provided by the invention improves the environmental friendliness of the water-based glass frosting powder during application and improves the treatment performance of the glass surface roughness. DETAILED DESCRIPTION
