Technical Field

The invention relates to the field of powder ink manufacturing, in particular to a self-preparation method of a color high-temperature ceramic raw material.

Background

In the ceramic industry, the patterns on the surface of the ceramic are generally realized by manual drawing or screen printing, however, the manual drawing speed is slow, the efficiency is low, and the drawing is limited by the skill of a drawer. The silk-screen printing can realize mass production, the production efficiency is greatly improved, but the silk-screen printing is quite complicated for color patterns, for example, the plate making needs to firstly carry out color separation, then a plurality of color plates are manufactured, then different colors are needed to be printed on the surface of the ceramic one by one, and then the ceramic surface is respectively sintered, and finally the color patterns are obtained. Although screen printing has a good effect on general patterns, in practice, the colors of photos cannot be truly expressed for portrait photos, and problems such as unnatural color pattern transition, low resolution and the like exist, so that the method is not suitable for manufacturing portrait photos.

Based on this, the inventors have invented an ink-jet process for the preparation of a porcelain image by separating the colors of the portrait by a computer, then printing a color on a porcelain plate with a glue by an ink-jet printer, then pouring the color powder of the color, sweeping the pattern with a brush, sticking the color powder on the pattern, baking the pattern at a low temperature to 100 ℃, after the layer is dried, sequentially printing the cyan, yellow and magenta with the glue, sweeping the powder, drying, and finally firing the image at 800 ℃.

In the last 90 s, the ceramic carbon powder for the laser printer was invented abroad, the ceramic carbon powder can be directly printed on stained paper, the stained paper is pasted on the surface of ceramic, and patterns are obtained after high-temperature sintering. However, because of the special characteristics of ceramic pigments, some pigments react to change color when being sintered at high temperature, and the color of the magenta prepared is generally light, and when the carbon powder is used for portrait printing, the picture can be faded. In addition, foreign ceramic carbon powder is quite expensive, and the use of ceramic carbon powder by people is limited. Therefore, the components of the ceramic carbon powder need to be optimized, and on one hand, the imaging pattern needs to be exquisite and not easy to fade; in addition, such toners should reduce manufacturing costs and thereby reduce the economic burden on the end user.
