Description

Technical Field

[0001] The invention relates to the technical field of microcrystalline glass plate manufacturing, and in particular to a manufacturing process of an imitation fire-burned stone microcrystalline glass plate. Background Art

[0002] With the rapid development of modern architecture and interior decoration industry, people have higher and higher requirements for decorative materials. As a new type of decorative material, imitation fire-burned stone micro-ceramic glass plate is gradually favored by the market for its unique appearance and excellent performance.

[0003] The existing production processes of imitation fire-burned stone micro-ceramic glass panels on the market have many shortcomings. On the one hand, some production processes are relatively complicated, involving multiple processes and complex equipment operations, which not only increases the time and labor costs of production, but also places high demands on the technical level of operators. For example, some traditional processes require the use of specific expensive equipment, and the debugging and maintenance of the equipment are also cumbersome.

[0004] On the other hand, the cost of products made by existing processes is relatively high. Due to the complex production process and reliance on high-end equipment, the costs of raw materials, equipment depreciation, and labor costs remain high, which to a certain extent limits the application of imitation fire-burned stone micro-ceramic glass panels in a wider market.

[0005] In addition, unstable product quality is also an important problem facing the current process. Different batches of products may have large differences in appearance, performance, etc., which brings troubles to consumers' choices and use, and also affects the reputation and market competitiveness of manufacturers. For example, in the etching process, the etching depth and uniformity are difficult to control accurately, which may lead to inconsistent product surface effects; in the spraying process, the thickness, adhesion and other properties of the coating may also vary due to fluctuations in process parameters. Summary of the invention In view of the shortcomings of the prior art, the present invention solves the technical problems by adopting a technical solution: a process for manufacturing a fire-burned stone micro-ceramic glass plate, comprising the following steps: Step 1: Use a sandpaper polisher to polish the surface of the glass plate to form a "fog-like" structure on the surface of the glass plate; the polishing parameters of the sandpaper polisher include: using sandpaper between 800-1200 mesh, the polishing pressure is 2-5 Newtons, and the polishing time is 5-10 minutes; Step 2: AG etching is performed on the glass plate with a foggy structure; Step 3: Use a rotary wool wheel polisher to grind and polish the surface of the etched glass plate; Step 4: Spray coating on the polished glass surface.

[0006] Preferably, the process parameters of the AG etching include etching solution composition, etching temperature and etching time.

[0007] Preferably, the polishing parameters of the rotary wool wheel polishing machine include wool wheel material, polishing pressure and polishing time.

[0008] Preferably, the anti-fingerprint coating composition and spraying process parameters used in the spraying process are Preferably, the specific steps of performing AG etching on a glass plate having a "foggy" structure are as follows: Step 1: Preparation stage, first check the state of the etching equipment to ensure that it is well sealed and all parts are operating normally; then, prepare the etching solution according to the specific formula, add acids, oxidants, corrosion inhibitors, chelating agents, stir, and adjust the temperature and pH value of the etching solution to the appropriate range; then, clean the glass plate with a "fog" structure to remove impurities such as dust and oil on the surface to prepare for etching. This stage is the basis for successful etching and ensures that the equipment and materials are in the best condition; Step 2: Etching process, put the prepared glass plate into the etching tank, use immersion etching to make the glass plate completely immersed and not in contact with each other, start the stirring device and heating device to keep the etching liquid flowing evenly and at a constant temperature. During the etching process, regularly observe the etching of the glass plate through a microscope, including etching depth, uniformity and surface quality, and adjust the etching parameters according to the actual situation to avoid problems such as over-etching or uneven etching. This stage requires strict monitoring to ensure that the etching effect meets the requirements; Step 3: After the processing is completed, when the glass plate reaches the desired etching effect, stop the etching equipment and take out the glass plate, rinse the glass plate with pure water to remove the residual etching liquid and impurities, and then dry it. Finally, conduct quality inspection, including appearance inspection, size measurement and performance testing, to ensure that the quality and performance of the glass plate meet the application requirements. The processing and inspection at this stage are the key links to ensure product quality.

[0009] Preferably, the specific method for adjusting the etching temperature and pH value is as follows: Adjustment of etching solution temperature: First, use a water bath for heating, place the etching tank in a container filled with water, and heat the etching solution indirectly by heating the water. During the temperature adjustment process, use a thermometer to monitor the temperature of the etching solution in real time. Select a digital thermometer and insert it into the etching solution. According to the etching requirements, control the temperature between 30°C and 50°C. At the same time, use a temperature controller to automatically adjust the temperature of the etching solution. The temperature controller automatically controls the working state of the heating device according to the set temperature value to keep the temperature of the etching solution within a stable range. Adjustment of pH value of etching solution: Add acid or alkali to adjust pH value. If the pH value of etching solution is greater than seven, acidic substances such as phosphoric acid and nitric acid inorganic acid, or acetic acid and citric acid organic acid can be added to lower pH value. On the contrary, if pH value is too low, alkaline substances such as sodium hydroxide and potassium hydroxide can be added. In the process of adding acid or alkali, use pH meter to monitor the pH value change of etching solution in real time. Insert the electrode of pH meter into etching solution, read the current pH value, and adjust pH value according to the formula of etching solution and etching requirements. Generally speaking, pH value of etching solution needs to be kept within a certain acidic range to promote etching reaction. pH value can also be adjusted indirectly by controlling the proportion of each component in etching solution. For example, increasing the proportion of acidic components may reduce pH value, while increasing the proportion of alkaline components such as corrosion inhibitor may increase pH value.

[0010] Preferably, the acid, oxidant, corrosion inhibitor, and chelating agent are hydrochloric acid, hydrogen peroxide, benzotriazole, and ethylenediaminetetraacetic acid, respectively. Hydrochloric acid provides hydrogen ions and reacts with the silicon dioxide component in the glass to achieve etching. Hydrogen peroxide promotes the etching reaction and increases the etching rate. Benzotriazole forms a protective film on the glass surface during the etching process to slow down excessive etching of the glass and protect the structure and performance of the glass. Ethylenediaminetetraacetic acid forms a stable chelate with metal ions to prevent metal ions from contaminating the etching solution and maintain the stability of the etching solution. Hydrochloric acid accounts for 15-25 parts, hydrogen peroxide accounts for 8-12 parts, benzotriazole accounts for 0.2-0.4 parts, and ethylenediaminetetraacetic acid accounts for 0.6-1 parts. The etching solution is added in a proportion of 15-25 parts, 8-12 parts, 0.2-0.4 parts, and 0.6-1 parts. Mechanical stirring is adopted, and a stirring paddle is used to stir at a speed of 50-100 revolutions per minute in the etching solution container for 15-30 minutes. At the same time, the state of the etching solution is observed during the stirring process.

[0011] Preferably, the specific steps of observing the etching condition of the glass plate are as follows: Step 1: prepare an optical microscope and a magnifying glass, select four points on the edge of the glass plate and a straight line position from the etched glass plate, cut out a cross section, observe the cross section with an optical microscope, estimate the height difference between the etched area and the unetched area, record the values ​​at several positions and take the average value as a preliminary judgment of the etching depth; Step 2: Randomly select multiple observation points on the surface of the glass plate, first use the naked eye to observe whether the etching degree of each observation point is similar, and then use a magnifying glass to further check the difference in surface texture characteristics. If the difference is small, it means that the uniformity is good. If the difference is obvious, it is uneven. Step 3. Observe the surface of the glass plate directly with the naked eye to check for obvious scratches, spots, and bubbles. For areas suspected of having problems, use a magnifying glass to further inspect them and confirm the defects.

[0012] Preferably, the drying process is performed by hot air drying, the drying time is 10-20 minutes, and the drying temperature is 50-80°C.

[0013] The beneficial effects of the present invention are as follows: The manufacturing process of the present invention avoids complicated equipment operation and cumbersome procedures by rationally optimizing each step. For example, in the sandpaper polishing process, a common sandpaper polishing machine is used, and specific polishing parameters are clarified to make the operation easier. In the AG etching process, by accurately controlling parameters such as the etching liquid composition, temperature and pH value, the stability and controllability of the etching are improved, and the scrap rate caused by unstable parameters is reduced. In the spraying process, the cleaning steps before spraying, the adjustment of spray gun parameters, and the drying time of multi-layer spraying are clarified to ensure the quality of the coating. These optimization measures make the entire manufacturing process simpler and easier, reduce the requirements for the technical level of the operator, and thus reduce labor costs.

[0014] At the same time, by rationally selecting raw materials and optimizing process parameters, the consumption of raw materials and the depreciation cost of equipment are reduced. For example, in the selection of etching solution components, common substances such as hydrochloric acid, hydrogen peroxide, benzotriazole and ethylenediaminetetraacetic acid are used, which are relatively cheap and easy to obtain. In the spraying process, nano-silicon dioxide is selected as anti-fingerprint and wear-resistant coating, which not only has good performance but also has relatively low cost. In addition, by optimizing process parameters, such as controlling the spraying parameters of the spray gun and the drying time of multi-layer spraying, the waste of coating can be reduced and the cost can be further reduced.

[0015] After sandpapering to form a mist-like structure, AG etching can make the surface of the glass plate present a unique texture and texture similar to that of fire-burned stone. During the etching process, by precisely controlling parameters such as the etching liquid composition, temperature and time, the etching depth and uniformity can be precisely controlled, making the texture on the surface of the glass plate more natural and realistic. For example, by adjusting the ratio of components such as hydrochloric acid and hydrogen peroxide, the etching speed and depth can be controlled; by controlling the etching temperature and time, the etching uniformity can be ensured.

[0016] Finally, spraying the glass surface can not only increase the wear resistance and anti-fingerprint performance of the glass, but also further improve its decorative effect. Choosing nano-silicon dioxide as the coating can make the glass surface smooth and delicate, while also having good transparency, and will not affect the appearance of the glass.

[0017] The imitation fire-burned stone micro-ceramic glass plate produced by the present invention has excellent properties such as wear resistance and anti-fingerprint. In the spraying treatment process, nano-silicon dioxide is used as a coating to form a solid protective film on the surface of the glass plate, effectively improving the wear resistance and anti-fingerprint performance of the glass plate. At the same time, during the AG etching process, benzotriazole forms a protective film on the glass surface to slow down the excessive etching of the glass and protect the structure and performance of the glass.

[0018] In addition, through strict quality inspection and control, the quality of the products is ensured to be stable. During the production process, quality inspection is carried out on each link, including appearance inspection, dimension measurement, performance test, etc. For example, when drying after etching, hot air drying is used to control the drying time and temperature to ensure the drying effect and quality of the glass plate surface. After the coating is dried and cured, the glass plate is quality inspected to check whether the coating's appearance, thickness, adhesion and other properties meet the requirements. These quality control measures ensure the stable performance of the product and extend the service life of the product. DETAILED DESCRIPTION

If the coating quality is qualified, the glass plate will be packaged. The packaging material should be foam plastic to ensure that the packaging is firm and reliable. At the same time, the glass plate should be stored in a dry, ventilated, and light-proof place.
