Problems solved by technology

Such tiny particles are easily oxidized under high temperature conditions, and the difficulty of color development can be imagined. At present, there are "cadmium-selenium red-wrapped pigments" that can emit bright red in the world. The particle size is 4-10μm, such as To prepare bright red ink with it, it is necessary to use a sand mill to grind it to below 2 μm, and the coating layer of zirconium silicate will be destroyed during the grinding process, which will lead to the oxidation and decomposition of cadmium sulfur selenide pigment particles in the high temperature calcination process, making large Redness fades or even loses color
Therefore, scarlet ink has always been a problem that is difficult to overcome in the global industry. The existing technology generally uses brown ink or pink ink to replace scarlet ink, resulting in low lightness of ceramic inkjet printing patterns, not bright enough colors, narrow saturation color gamut, and poor patterns. easily distorted

Description

technical field [0001] The invention belongs to the technical field of ceramic printing and dyeing, and in particular relates to a high-temperature-resistant ceramic scarlet ink and a preparation method thereof. Background technique [0002] The development history of ceramics is an important part of the history of Chinese civilization. The invention and development of ceramics has unique significance in Chinese history. With the development of modern science and technology, many new ceramic varieties have appeared in the past century. They no longer use or rarely use traditional ceramic raw materials such as clay, feldspar, and quartz, but use other special raw materials. [0003] In order to improve the artistry and grade of ceramic products, ceramic decoration came into being. Ceramic decoration Various ways and techniques of artistic processing on ceramics; traditional ceramic decoration is to glaze the body to form patterns and colors on the ceramics. With the develop...
