Description

Technical Field

[0001] The present invention relates to the technical field of high-temperature resistant ceramic powder coatings, and particularly to a high-temperature resistant ceramic powder coating, a preparation method thereof, and a processing device therefor. Background Art

[0002] Powder coatings are solid powder synthetic resin coatings composed of solid resins, pigments, fillers, and additives, etc. Without using solvents, they have the characteristics of no solvent pollution, 100% film formation, and low energy consumption. Their application fields are extensive, such as wall and roof painting in the construction industry, coating treatment in the furniture manufacturing industry, component painting in the automotive industry, and anti-corrosion painting of metal products, agricultural machinery, etc. Powder coatings are not only beautiful but also can effectively protect the product surface and extend the service life.

[0003] Ceramic coatings are a new type of coating that can cause reactions between organic and inorganic substances, thus combining the advantages of both. The characteristics of this coating are high hardness, high temperature resistance (up to over 400 degrees), non-stick, diverse colors, and can be made into waterborne coatings with excellent weather resistance and processing performance. The application fields of ceramic coatings are very extensive, mainly including industrial fields such as power generation, chemical industry, coal, and steel, for anti-corrosion, wear resistance, and high-temperature protection of equipment. In addition, due to its excellent weather resistance and processing performance, ceramic coatings are also suitable for painting the interior and exterior walls of buildings, as well as surface treatment of products such as automobiles, high-speed rails, kitchen equipment, and air conditioners, which can improve the hardness and pollution resistance of the products.

[0004] The raw materials commonly used in ceramic coatings include clay, quartz, feldspar, and porcelain stone, etc. These raw materials need to go through steps such as mixing, crushing, and screening to ensure the uniformity and purity of the raw materials.

[0044] A loading table 3 is fixedly connected inside the processing box 103, and a pair of roller pressing plates 301 are rotatably connected inside the loading table 3. The prepared raw materials are placed into the roller pressing plates 301. The reciprocating rolling of the pressure roller 213 facilitates the crushing of the raw materials inside the roller pressing plates 301. After the crushing is completed, the telescopic rod 303 expands and contracts, and the roller pressing plates 301 open. The crushed raw materials directly fall onto the screening assembly for screening work;

[0045] When the raw materials crushed inside the roller pressing plates 301 fall onto the sieve plate 403, the second motor 411 operates. The operation of the second motor 411 causes the transmission shaft 409 to rotate. A disc 408 is fixedly connected to one end of the transmission shaft 409. The rotation of the transmission shaft 409 causes the disc 408 to rotate. A limiting shaft 407 is fixedly connected to the disc 408, and a transmission plate 406 is sleeved on the limiting shaft 407. The rotation of the disc 408 causes the transmission plate 406 to pull the sieve plate 403 to perform a reciprocating motion, thereby facilitating the screening of the crushed raw materials by the sieve plate 403.
