Description

Technical Field

[0001] The present invention belongs to the technical field of ceramic manufacturing processes, and specifically relates to a manufacturing process for forming natural three-dimensional patterns on the surface of ceramics. Background Art

[0002] China has a long history of ceramic production. The production history of Chinese ceramics is long and glorious, with extremely rich cultural connotations, which can be described as extensive and profound. The original meaning of the English word "CHINA" was porcelain. Since Chinese ancient ceramics have been exported to all over the world for thousands of years, with a wide reputation overseas, the word "CHINA" has evolved into the meaning of "China". Because Chinese ancient ceramics have unique artistic charm and have had a huge impact worldwide, people have been willing to collect Chinese ancient ceramics since ancient times. In the process of appreciating and studying ancient ceramic collections, people recall the long history of the motherland and the splendid culture of the nation, cultivate their self-cultivation, refine their sentiment, enrich their spiritual life, form various rational perceptions, and improve their own qualities.

[0003] China is also the world's largest ceramic producer. Ceramic products are one of the main products for earning foreign exchange through exports in China. Adding textures and colors to ceramics is mainly achieved through glazing, which is usually divided into overglaze color painting and underglaze color painting. Overglaze color painting is to paint on the fired plain ware and then bake it at a low temperature. The color is attached to the glaze surface. Underglaze color painting is to paint on the green body and then apply glaze and fire it at a high temperature. The color pattern is under the glaze. However, the ceramics made by this method are all made at room temperature or high temperature. Therefore, the traditional ceramic manufacturing has disadvantages such as long production cycle, long training and learning time for technicians, complicated manufacturing processes and materials. In addition, the ceramics manufactured by traditional technologies also have problems such as mostly smooth surfaces, lack of depth and three-dimensional sense, and high requirements for the manufacturing skills of technicians.

[0004] In view of this, the present invention is specifically proposed. Summary of the Invention

[0005] To solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0006] A manufacturing process for forming natural three-dimensional patterns on the surface of ceramics, including the following working steps:

[0007] The first step: Prepare ceramic coatings;

[0008] The second step: Spray or dip;

[0009] The third step: Place the ceramic products after spraying or dipping in a natural sub-zero environment or equipment;

[0010] The fourth step: Fire.

[0011] As a preferred embodiment of the present invention, the preparation of the ceramic coating in the first step specifically includes the following steps: preparing 20-60 parts of kaolin, 5-15 parts of quartz, 20-40 parts of water, 0.2-0.8 parts of silicon, 0.2-0.6 parts of aluminum, 0.1-0.2 parts of silver, 0.1-0.2 parts of rare earth, 2-3 parts of phosphorus, 1-4 parts of boron, 0.2-0.3 parts of titanium, and 0.2-0.3 parts of magnesium, and taking kaolin, rare earth, and quartz raw materials in parts by weight, putting them into a container, mixing and stirring the raw materials to make them uniform, and obtaining a mixture A; taking gelatin, silicon, boron, magnesium, titanium, phosphorus, and aluminum raw materials in parts by weight, putting them into a container, mixing and stirring the raw materials to make them uniform, and obtaining a mixture B.

[0012] As a preferred embodiment of the present invention, raw material mixture A and mixture B are taken by weight, put into a ceramic preparation machine, and stirred thoroughly. Water is added in proportion during stirring, and the ceramic coating is obtained after being stirred thoroughly and evenly.

The temperature range is minus 1°-minus 100°. Depending on the required pattern, the time range for producing the pattern is 1-30 minutes. After the pattern is formed, the negative pressure equipment is started to make the equipment negative pressure, so that the moisture in the paint is vaporized and dried. The time can be reduced by more than 30 hours compared with the drying in the natural environment.

[0016] As a preferred embodiment of the present invention, the fourth step specifically includes: placing the ceramic product after the coating is dried into a kiln for firing, and naturally cooling to room temperature after firing at 1000°-1400° to obtain a ceramic product with natural patterns and textures.

[0021] Figure 1 It is a schematic diagram of the equipment in the third step of the present invention. DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0023] A process for forming a natural three-dimensional pattern on a ceramic surface, comprising the following steps:

[0024] Step 1: Prepare ceramic coating;

[0025] Step 2: spray or dip;

[0026] Step 3: Place the sprayed or stained ceramic products in a sub-zero natural environment or equipment;

[0027] Step 4: Firing.

[0028] The preparation of the ceramic coating in the first step specifically includes the following steps: preparing 20-60 parts of kaolin, 5-15 parts of quartz, 20-40 parts of water, 0.2-0.8 parts of silicon, 0.2-0.6 parts of aluminum, 0.1-0.2 parts of silver, 0.1-0.2 parts of rare earth, 2-3 parts of phosphorus, 1-4 parts of boron, 0.2-0.3 parts of titanium, and 0.2-0.3 parts of magnesium, taking kaolin, rare earth, and quartz raw materials in parts by weight, putting them into a container, mixing and stirring the raw materials to make them uniform, and preparing mixture A; taking gelatin, silicon, boron, magnesium, titanium, phosphorus, and aluminum raw materials in parts by weight, putting them into a container, mixing and stirring the raw materials to make them uniform, and preparing mixture B. Taking raw material mixture A and mixture B in parts by weight, putting them into a ceramic preparation machine, stirring them fully, adding water in proportion during stirring, and stirring them fully to prepare the ceramic coating.

[0029] The second step specifically includes selecting spraying or dipping according to the device type or design requirements.

[0030] The specific steps of the third step include: in a sub-zero natural environment, the coating reacts according to the temperature for 5 - 30 minutes. After the reaction is completed, it continues to dry naturally for 72 hours. The temperature of the sub-zero natural environment is from -1°C to -40°C.

[0031] The specific steps of the third step also include: The equipment specifically includes as Figure 1 shown. The equipment includes a door 1, a door 2, a refrigerator, a negative pressure device, and the sealed room where they are located. In the equipment, the ceramic product with the coating needs to be put into the equipment. The equipment can control the temperature through the refrigerator and drive the cold air flow through the leaf angles of the door 1 and the door 2 to control the direction and shape of the pattern generated by the coating. The temperature range is from -1°C to -100°C. According to different patterns required, the time range for generating the pattern is 1 - 30 minutes. After the pattern is formed, start the negative pressure device to make the inside of the equipment in a negative pressure state, vaporize and dry the water in the coating. The time can be reduced by more than 30 hours compared with natural drying.

[0032] The specific steps of the fourth step include: putting the ceramic product after the coating is dried into a kiln for firing. After firing at 1000°C - 1400°C, it is naturally cooled to room temperature to obtain a ceramic product with natural pattern textures.

[0033] Generally speaking, the present invention uses the formulated ceramic coating to form natural random or specified engraving-like patterns on the ceramic surface (regardless of whether it is glazed or the shape of the ware) and the glass surface through the distribution reaction from -30°C to 1300°C. The coating functions to form a transparent or colored engraving layer on the ceramic surface. On the already formed porcelain (fired at 1000°C - 1400°C), the coating is evenly sprayed or dipped on the ceramic surface to completely or partially apply the coating to the ceramic surface. The coating undergoes a low-temperature reaction in a sub-zero natural environment or equipment, and the coating will generate natural pattern textures with engraving depths. For example, in a natural environment, after the texture of the coating is formed by the low-temperature reaction, it is necessary to wait for the water in the coating to naturally evaporate and dry. In a special equipment, the ceramic with the coating needs to be put into the equipment for sub-zero reaction and drying, which can accelerate the reaction time and drying time for forming the pattern. The direction of the pattern texture can also be controlled. The dried ceramic needs to be put into a kiln for high-temperature firing (selecting firing at 1100°C - 1400°C according to the texture requirements) to make the pattern generated by the coating integrate with the ceramic body.

[0034] The present invention solves the problem that traditional ceramic surface art can only be made at normal temperature or high temperature, enables natural pattern textures to be generated on the ceramic surface even at sub-zero temperatures, solves the problems of long production cycle, long training and learning time for technicians, and complicated production processes and materials. The present invention can be mass-produced in a pipeline form. The present invention combines modern technology to make the ceramic surface no longer flat, makes the ceramic products no longer lack three-dimensional sense, is easy to operate, has strong artistry of the finished products, and novel workmanship.

Additionally, under the teaching of the present invention, these features and embodiments can be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application belong to the scope protected by the present invention.
