Problems solved by technology

[0004] Advertising paints have been widely used. However, there is still room for improvement in the performance of advertising paints in the prior art in terms of tinting strength, lightness and crack resistance. In addition, in the prior art, natural peach gum is usually used to synthesize glue so that Further make advertising paint, because natural peach gum color is very deep and smelly, so the advertising paint that is prepared has heavy smell, and the color is not bright and beautiful, in addition, the advertising paint in the prior art adopts phenol or formaldehyde as preservative , these substances will cause certain damage to the environment; on the other hand, the composition of advertising paints in the prior art is complex, and phenomena such as phase separation are prone to occur

Abstract

The invention provides pigment for advertising posters and a preparation method of the pigment. The pigment for the advertising posters is prepared from 50-60 parts of organic pigment, 2-5 parts of a defoaming agent, 2-5 parts of a dispersing agent and 30-40 parts of water, wherein a preparation method of the organic pigment comprises steps as follows: nanometer white carbon black is modified with chloropropyl triethoxy silane on surface, quinacridone is ionized and subjected to ion exchange, quinacridone after ion exchange is modified with Arabic gum and the like. The preparation method of the pigment for the advertising posters comprises steps as follows: firstly, water, the defoaming agent and the dispersing agent are dissolved and mixed, then the organic pigment is added, all components are mixed uniformly at the temperature of 60-100 DEG C, finally, the uniform mixture is ground by a three-roll grinder, and fineness is enabled to be 30-40 mu m. The preparation method of the pigment for the advertising posters is simple, easy, low in cost and high in tinting strength, brightness and crack resistance, and has bright and beautiful colors and good market application prospect.
