Dyeing slurry for preparing color ceramics

Abstract

The invention discloses dyeing slurry for preparing color ceramics. The dyeing slurry is prepared from the following ingredients in parts by weight: 0.01 to 80 parts of pigments, 5 to 95 parts of glass powder, 1 to 30 parts of bonding agents, 0.1 to 5 parts of dispersing agents, 1 to 5 parts of plasticizers and 10 to 80 parts of organic solvents. The dyeing slurry for preparing color ceramics has the advantages that during the preparation of color ceramics, the dyeing slurry can be directly coated on a ceramic base plate; through sintering, polishing and the like, a dyeing layer with uniform and adjustable color is formed on the ceramic base plate, so that the color ceramics prepared from the dyeing slurry has the advantages that the color fading cannot easily occur; the coloring is uniform; the color precision is high; the color is adjustable; the surface mirror surface is smooth; the intensity of the ceramic body cannot be influenced, and the like.

Description

technical field [0001] The invention relates to a dyeing paste, in particular to a dyeing paste which can be used for preparing colored ceramics. Background technique [0002] Ceramic materials have excellent characteristics such as high strength, high hardness, good wear resistance and corrosion resistance, and are widely used in various fields, such as knives, watch cases, molds, mobile phone cases and various ceramic structural parts. In recent years, with the continuous improvement of people's requirements for decorations, colored ceramics have become the new favorite in the field of high-end decoration due to their excellent mechanical properties, bright and elegant tones, metallic luster, environmental friendliness, non-toxic and non-allergic characteristics, such as pressing Ceramic cover plates for fingerprint recognition, high-end watch cases, watch chains, mobile phone cases and high-end buttons, etc. However, most of the colored ceramics currently produced are li...

AI Technical Summary

Problems solved by technology

However, most of the colored ceramics currently produced are limited to black and white, and the preparation process of traditional colored ceramics (such as ball milling, etc.) is complicated, which is easy to cause problems such as uneven coloring and mutual contamination of colorants. These factors limit the color ceramics. production and wider application

[0003] Patent CN101643351A discloses a preparation process of colored ceramics, which mainly achieves the effect of preparing colored ceramics by adding a dyeing agent to ceramic powder. Although this method can make ceramics colored, due to the complicated preparation process, It is easy to cause problems such as uneven coloring, low color accuracy, poor color selectivity and high cost
