Description

Technical Field

[0001] The invention belongs to the technical field of ceramic wine bottles, and in particular relates to a ceramic wine bottle crack glaze and a preparation method thereof. Background Art

[0002] At present, there are many materials for wine containers on the market, including ceramics, glass, plastics, aluminum products, wooden barrels, etc. Although the packaging materials of wine are becoming more and more abundant and diverse, the packaging materials of high-end wines on the market are mostly ceramic products. The reasons are as follows: Ceramic wine bottles are opaque, which avoids the reaction of light to wine and can better maintain the quality of wine; ceramic wine bottles have slow heat conduction, and the temperature in the wine bottle is relatively low, making the wine less likely to deteriorate; ceramic wine bottles have certain air permeability, and there are certain pores in their molecular structure, which is very conducive to the air permeability of white wine. Ceramic containers can allow wine to exchange with the outside air, which is very beneficial to the quality of wine. With the increasing application of ceramic wine bottles, people have higher and higher requirements for the aesthetics of ceramic wine bottles. Among them, ceramic wine bottles with beautiful cracks on the surface are the most popular, and the core technology of the preparation process of ceramic wine bottles with beautiful cracks is the preparation of crack glaze.

[0003] At present, the expansion coefficient of the ceramic bottle crack glaze is 300×10 -7 / ℃ or above glaze, through a matching firing process, can produce a wine bottle with a crackle aesthetic. However, the formation of crackle glaze increases the difficulty of cleaning the wine bottle. Dust and dirt easily accumulate in the cracks and are difficult to completely remove, which not only affects the appearance of the wine bottle, but may also pose a potential threat to the sanitary quality of the wine. Summary of the invention

[0004] The purpose of the present invention is to provide a ceramic wine bottle crack glaze and a preparation method thereof, so as to solve the problem that the crack wine bottle is difficult to clean in the prior art.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A ceramic wine bottle crackle glaze comprises the following raw materials in parts by weight: 60-70 parts of crackle frit, 2-8 parts of modified photocatalytic components, 18-22 parts of potassium feldspar, 5-7 parts of Guizhou clay, 1-3 parts of bentonite and 4-6 parts of calcite.

[0007] Furthermore, the above-mentioned ceramic wine bottle crack glaze includes the following raw materials in parts by weight: 65 parts of crack frit, 5 parts of modified photocatalytic component, 20 parts of potassium feldspar, 6 parts of Guizhou soil, 2 parts of bentonite, and 5 parts of calcite.

[0008] Furthermore, the crack frit comprises the following chemical components in parts by weight:

[0009] S i O 2 50-60 copies, A l2 O 3 5-13 parts, CaO 4-7 parts, Na 2 O 12-17 parts, BaO 2-6 parts, B 2 O 3 13-17 servings.

[0010] Furthermore, the preparation method of the modified photocatalytic component comprises the following steps:

[0011] The titanate coupling agent was added to anhydrous ethanol, and magnetic stirring was performed at 30° C. for 30 minutes. Then, the photocatalytic component was added, stirring was continued for 6-8 hours, and finally dried for 12 hours to obtain the modified photocatalytic component.

[0012] Furthermore, the amount of the titanate coupling agent is 1-3% of the mass of the photocatalytic component.

[0013] Furthermore, the photocatalytic component is a composite material of titanium aluminum carbide and silver phosphate.

[0014] Furthermore, the method for preparing the photocatalytic component comprises the following steps:

[0015] The pretreated titanium aluminum carbide was ultrasonically dispersed in deionized water, and then Na 2 HPO 4 12H 2 0 aqueous solution, after the addition is completed, stir the reaction at a speed of 20-60r / min for 2h, then add the silver nitrate aqueous solution and continue stirring for 4-6h. After the stirring is completed, filter and wash the filter cake repeatedly with deionized water and anhydrous ethanol until the washing liquid is neutral, and finally dry it in vacuum at 60°C to constant weight to obtain a photocatalytic component.

[0016] Furthermore, in the above preparation process, titanium carbide aluminum, Na 2 HPO 4 12H 2 0 and silver nitrate in a ratio of 66.7 mg: 0.13-0.43 g: 0.33-1.5 g to pretreat titanium carbide, aluminum, Na 2 HPO 4 12H 2 0 and silver nitrate as raw materials to prepare titanium aluminum carbide and silver phosphate composite materials. The existence of heterojunction between titanium aluminum carbide and silver phosphate makes it have strong charge separation ability and excellent photocatalytic performance.

[0017] Furthermore, the method for preparing the pretreated titanium aluminum carbide comprises the following steps:

[0018] Heat deionized water to boiling, add sodium hydroxide and titanium aluminum carbide (Ti 3 Al C 2), transfer to a hydrothermal reactor after stirring evenly and introduce argon to deoxygenate, perform hydrothermal reaction at 240°C for 24h, wash with deionized water until the washing liquid is neutral after cooling, and dry at 60°C for 6h;

[0019] In the above preparation process, the usage ratio of deionized water, sodium hydroxide and titanium aluminum carbide is 25mL:30g:0.08-0.1g. After etching with alkaline water, titanium aluminum carbide shows an obvious layered structure, which is more conducive to the subsequent loading of silver phosphate.

[0020] A method for preparing a ceramic wine bottle crack glaze comprises the following steps:

[0021] According to the formula requirements, the ingredients are weighed and put into a ball mill for wet ball milling. After ball milling, the materials are sieved through a 160-mesh sieve to obtain a ceramic wine bottle crack glaze.

[0022] Furthermore, the mass ratio of raw material, ball stone and water in the ball milling process is 1:1.4-1.7:1-1.3.

[0023] Beneficial effects of the present invention:

[0024] 1. The present invention provides a crack glaze for a ceramic wine bottle and a preparation method thereof. The glaze consists of crack frit, modified photocatalytic components, potassium feldspar, Guizhou clay, bentonite, and calcite components. The components cooperate with each other. During the high-temperature sintering process, the glaze surface can generate a large tensile stress, so that many cracks are formed on the glaze surface, thereby obtaining a decorative effect of the cracks and improving the grade and texture of the ceramic wine bottle. In addition, the glaze surface formed by high-temperature sintering of the glaze also has good self-cleaning performance. Under the irradiation of visible light, it can catalytically degrade pollutants on the glaze surface, especially dirt in the cracks, thereby greatly improving the sanitary conditions of the ceramic wine bottle during use.

[0025] 2. The modified photocatalytic component in the present invention is a composite material of titanium aluminum carbide and silver phosphate treated with a titanate coupling agent. The coupling agent treatment improves the dispersibility of the photocatalytic component in the glaze and reduces adverse effects such as agglomeration. On the other hand, the titanium dioxide produced by the high-temperature sintering of the titanate coupling agent is beneficial to enhancing the photocatalytic, antibacterial and other properties of the glaze. The photocatalytic component is titanium aluminum carbide in situ loaded with silver phosphate, which not only has excellent photocatalytic properties but also has good antibacterial properties, can reduce the growth of bacteria on the glaze and improve the safety of wine bottles. In addition, the introduction of modified photocatalytic components can also improve the microstructure of the glaze and improve the strength of ceramic products.

[0026] 3. In the process of preparing the crack glaze for ceramic wine bottles, the present invention strictly controls the amount of modified photocatalytic components. When the amount is too low, it is difficult to effectively exert the photocatalytic and antibacterial effects. When the amount is too high, the glaze surface will be too brittle and hard, which will reduce the strength of the ceramic product.

[0027] 4. In the process of preparing the modified photocatalytic component, the amount of titanate coupling agent is strictly controlled in the present invention. If the amount of titanate coupling agent is too low, it is difficult to effectively improve the dispersibility of the photocatalytic component in the glaze, which will lead to a decrease in the comprehensive performance of the glaze, including self-cleaning, antibacterial, strength and other aspects. If the amount is too high, the photocatalytic component will be over-coated, affecting the contact of the photocatalytic component with light and bacteria, resulting in a decrease in the self-cleaning and antibacterial properties of the glaze.
