Abstract

The invention discloses a high-temperature water-based high-covering-power white ink and a preparation method thereof. The white ink is prepared by mixing and grinding 40-60% by mass of a glass-basedglaze, 15-35% by mass of ink adjusting oil and 15-35% by mass of titanium dioxide. A heat-resistant material component in the glass-based glaze enables the prepared ink to have good high-temperature resistance, and to adapt to the application environment in which the temperature changes drastically. A water-grinding manner is adopted in a preparation process of the glass-based glaze to improve glossiness of the glass-based glaze, reduce sand holes and improve covering power of the ink. After the water grinding, the method of filter pressing to remove water can effectively prevent the re-agglomeration of the material. The invention also provides a method of using the white ink. The white ink has strong covering power, good high-temperature resistance, high glossiness and excellent corrosionresistance, and the production process is environmentally friendly, and is suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of inks, and in particular relates to a high-temperature water-based high-covering white ink and a preparation method thereof. Background technique [0002] With the rapid progress of industrial manufacturing technology, the printing industry has also developed rapidly. Printing is to transfer text, pictures, photos, anti-counterfeiting and other original information through plate making, ink application, pressurization and other processes, so that the ink is transferred to the surface of paper, fabrics, plastics, leather and other materials. Technology that transfers content to the surface of the substrate. In the process of printing implementation, the selection of ink is an important step. According to different substrates and different use environments, choosing ink with suitable performance can well take into account the requirements of quality, environmental protection and cost in production. Traditi...
