The invention discloses high-temperature
cutting-resistant black ink and a preparation method thereof. The high-temperature
cutting-resistant black ink comprises the following raw materials in percentage by
mass: 30-50% of a glass-based
glaze, 25-35% of ink blending oil and 20-35% of
melanin. In the glass-based
glaze, thermal-resistant materials are mutually molten and fused, and the prepared black ink has good high
temperature resistance and in addition is applicable to use environments with acutely varied temperatures; by adopting a water
grinding mode, the gloss of the glass-based
glaze canbe improved, sand holes can be reduced, and the prepared ink is good in gloss and good in covering property; water is removed in a filter pressing mode, so that re-agglomeration of materials can be prevented. Due to the adoption of a low-
viscosity polyvinyl butyral resin, the blended ink is good in flowability, and ink construction conditions can be improved. The black ink disclosed by the invention is good in acid-alkali
corrosion resistance, after a cross-linking agent is used, an ink
coating is good in adhesion property and is very good in
cutting resistance, and meanwhile the black ink issimple and feasible in preparation method and applicable to industrial production. The invention further provides a use method of the high-temperature cutting-resistant black ink.
