Description

Technical Field

[0001] The invention relates to the technical field of ceramics and water transfer inks, in particular to a blue and white decal paper ink and a preparation method thereof. Background Art

[0002] Ceramic decals are a key method of surface decoration for ceramics. They are categorized into overglaze and underglaze decals, with blue and white decals belonging to the underglaze category. These decals are typically screen-printed and then water-transferred onto the desired ceramic body. After firing, the surface decoration is complete. Compared to traditional hand-painting and spray-painting techniques, ceramic decals are simpler and more suitable for mass production.

[0003] As people's living standards improve, the demand for exquisite ceramic decoration is also increasing. The existing blue and white decals have rough lines and are far from meeting people's requirements. The quality of decals depends primarily on the quality of the colorant and binder in the silk screen ink. Since the early 20th century, the binder system of malt sugar and white striata has been used. White striata powder is obtained by crushing the rhizomes of white striata. The quality is difficult to guarantee and the film-forming properties are unstable. The decals are prone to material flow and ink breakage during the water transfer process. The malt sugar and white striata aqueous solution is not easy to store and is prone to fermentation and deterioration. The unstable performance of the binder leads to uncontrollable ink quality, and the blue and white flower patterns after transfer are prone to defects, making it difficult to improve the refinement of the pattern.

[0004] Due to the short shelf life of the existing blue and white decal paper ink, the ink in production cannot be stored for a long time and must be prepared on the spot, which wastes raw materials and manpower. At the same time, as a film-forming agent and binder in the existing blue and white decal paper ink, the quality of white hyacinth powder fluctuates greatly and the performance is unstable. During the water transfer printing process of the decal paper, it is easy to flow and the ink is broken, resulting in a low product qualification rate. As a Chinese herbal medicine, white hyacinth powder has excellent medicinal value. The price of high-quality white hyacinth powder is getting higher and higher, which leads to increased product costs. The existing blue and white decal paper ink is obtained by mechanical stirring, and its uniformity is difficult to ensure. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the present invention provides a blue and white decal paper ink and a preparation method thereof, which has the advantages of high pattern fineness, not easy to break the ink and line missing; the fired pattern is complete and not easy to have the phenomenon of flower bursting, which prolongs the shelf life of the connecting material, improves the yield of blue and white decal paper products, and enhances the economic benefits of the enterprise, thereby solving the above-mentioned technical problems.
