Description

Technical Field

[0001] This invention belongs to the field of glass etching technology, and specifically relates to a frosting liquid for AG glitter frosting effect on automotive decorative glass and its preparation method. Background Technology

[0002] With the rapid development of the automotive industry, consumers' demands for the car's user experience have gone beyond conventional requirements such as power, chassis stability, and noise insulation. They are increasingly focusing on the interior's style and pursuing a personalized experience. Ambient lighting in cars is undoubtedly a new generation of fashionable features. Using AG glass with a frosted finish to cover the surface of the luminous light strips creates a more personalized and cool decorative effect, while also effectively protecting the light strips from wear and tear, making it very popular with consumers. Decorative frosted glass for cars has a stylish appearance, is scratch-resistant, and offers excellent personalized decorative effects, combining beauty and practicality.

[0003] Frosted glass is prepared using both physical and chemical methods. Physical methods, such as sandblasting or film application, achieve the frosted effect on the glass surface. However, this physical process results in frosted glass with poor adhesion, susceptibility to scratches, and a short lifespan, making it unsuitable for current automotive decorative glass needs. In contrast, frosted glass produced using chemical etching methods is scratch-resistant and has a longer lifespan. Existing chemical frosting solutions produce conventional AG glass and frosted glass with a dull, lackluster surface, limiting its decorative appeal and application in automotive decorative glass. Frosted glass, on the other hand, boasts a striking appearance and provides excellent decorative effects. However, current frosted glass used in automotive decorative glass suffers from uneven shimmer, a rough surface, insufficient fineness, high roughness, poor feel, and difficulty in cleaning as dirt easily accumulates on the surface.

[0004] Therefore, in order to solve the above problems, there is an urgent need to provide a new frosting liquid to obtain AG frosted glass with good uniform flashing effect, low roughness, fine sanding surface, silky feel, dirt not easily hiding on the glass surface, and easy cleaning and maintenance, so as to provide users with an excellent sensory and user experience. Summary of the Invention

[0005] In order to overcome the shortcomings and deficiencies of the prior art, the primary objective of this invention is to provide a frosting liquid for AG glitter frosting effect on automotive decorative glass.

[0006] The frosting solution provided by this invention, through the coordinated action of its components, can etch glass to obtain a uniform and delicate frosted surface with low roughness of 0.5-1.0 μm, silky smooth touch, high haze of 85%-100%, high brilliance, and good flashing effect. It effectively avoids the problems of rough frosted surface, rough touch, and excessive roughness in existing glass etching processes.

[0007] Another objective of this invention is to provide a method for preparing the above-mentioned frosting solution.

[0008] Another object of the present invention is to provide the application of the above-mentioned frosting liquid.

[0009] The objective of this invention is achieved through the following solution:

[0010] A frosting liquid for creating an AG glitter frosted effect on automotive decorative glass comprises the following components by weight percentage: 20-40% fluoride, 20-30% acidic additives, 10-20% salts, 1-2% hydrodynamic modifiers, and water as the balance.

[0011] As a solution of the present invention, the fluoride includes at least one of ammonium bifluoride and ammonium fluoride.

[0012] As a solution of the present invention, the acidic additive includes at least one of hydrochloric acid, sulfuric acid, nitric acid, phosphoric acid, lactic acid, malic acid, and benzoic acid.

[0013] As a solution of the present invention, the salts include at least one of sodium chloride, potassium sulfate, potassium acetate, zinc citrate, and ferric sulfate.

[0014] As a solution of the present invention, the fluid dynamics modifier may include at least one of guar gum, sodium polyacrylate, gum arabic, and polyurethane.

[0015] The frosting liquid for creating an AG (Aggregate Glitter) effect on automotive decorative glass in this invention utilizes the etching effect of fluorides on glass. Combined with acidic additives, salts, and hydrodynamic modifiers, it forms uniform and stable micro-particles. The AG frosted glass obtained by treating with this invention exhibits uniform high glitter, a bright surface, dense and compact sand patterns, fine texture, low roughness, and a silky feel. The roughness is controlled within a range of 0.5-1.0 μm, and the haze is 85%-100%. The resulting frosted surface not only provides a decorative effect but also features a silky feel, is less prone to dirt residue, and is easy to clean, resulting in an excellent aesthetic and user experience.

[0016] The present invention also provides a method for preparing the above-mentioned frosting liquid for the AG glitter frosting effect of automotive decorative glass, wherein the components are mixed in proportion and stirred evenly to obtain the product.

[0017] Furthermore, after the components are mixed, the solubility may decrease due to the heat absorbed by the solid dissolving in water, resulting in a large amount of solute precipitating out. This can be addressed by heating and stirring in a water bath to dissolve the solute before use.

[0018] Furthermore, the temperature of the water bath can be 40-60℃.

[0019] This invention also provides the application of the frosting liquid for the AG frosted effect on automotive decorative glass. The specific steps are as follows: add the frosting liquid for the AG frosted effect on automotive decorative glass of this invention into a frosting device, immerse the glass to be etched in the frosting liquid for frosting treatment, remove it, wash and dry it to obtain glass with a frosted effect.

[0020] Furthermore, the frosting treatment time can be 40-120 seconds.

[0021] Furthermore, the frosting liquid for the AG glitter effect on automotive decorative glass of the present invention can be used at a temperature of 10-25°C.

[0022] Furthermore, areas of the glass to be etched that do not require etching can be protected by screen printing with anti-etching ink.

[0023] Furthermore, the cleaning process can be completed by rinsing with water.

[0024] The frosting solution of this invention is easy to use, the frosting treatment conditions are mild, and excellent frosting effect can be achieved in a short time. The obtained frosted surface is uniform and delicate, with low roughness of 0.5-1.0um, silky touch, high haze of 85%-100%, high brilliance, and good flashing effect. It effectively avoids the problems of rough surface, rough touch, and large roughness of existing glass etching frosted surfaces.

[0025] The frosting solution of this invention utilizes the etching effect of fluorides on glass. Fluorides dissolve in water, and fluoride ions combine with hydrogen ions in the solution to form hydrogen fluoride, which etches the glass and is the effective component for glass frosting. An acidic additive dissolved in water provides hydrogen ions, which combine with the fluoride ions released by the effective component to form hydrofluoric acid, etching the glass. This provides a large number of hydrogen ions, ensuring reaction efficiency and allowing for thorough etching of the glass. Salts are used to provide the metal ions required for the reaction. The silicon tetrafluoride generated from the reaction of hydrogen fluoride and glass reacts with the metal ions in the solution to form fluorosilicate particles with low solubility, which uniformly adhere to the glass surface. This, along with a fluid dynamics regulator, regulates the frosting process. The fluid shear force between the frosting solution and the glass achieves optimal hydrodynamic effects, while simultaneously enhancing the adsorption of fluorosilicates on the glass surface. During the etching process, the glass oscillates evenly and systematically within the equipment, and the frosting solution etches the exposed glass surface in a regular manner. The fluorosilicates and the fluid dynamics regulator work together to control and regulate the contact time between the glass and the frosting solution, thereby preventing excessive localized corrosion of the glass. This invention utilizes the combined action of fluoride compound acidic additives, salts, and fluid dynamics regulators to form uniform and stable microparticles, resulting in a uniform and delicate frosted surface with low roughness and good shimmering effect. It effectively avoids the problems of uneven corrosion depth on the glass surface, which leads to a rough surface, a sticky feel, and excessive roughness. Attached Figure Description
