A kind of high gloss amino resin printing ink containing spherical silver powder

Abstract

The invention relates to the field of printing inks, in particular to a high-gloss amino resin printing ink containing spherical silver powder. The ink is made of the following raw materials in parts by weight: aluminum sol 4-5 with a solid content of 10-15%, nano-tin oxide 1-2, cypress oil 3-4, calcium laurate soap 1-3, spherical silver powder 0.1-0.2, fumed silica 3-5, ethyl acetate 30-40, organic pigment 12-14, amino resin 32-38 , diethyl carbonate 5-8, additives 2-4; the printing ink of the present invention is low-toxic and environmentally friendly, and has little harm to the environment and the human body. Raw materials such as aluminum sol, nano-tin oxide, and spherical silver powder can increase the hardness of the ink after drying , improve the dispersibility of pigments and fillers, enhance transparency and gloss, and the addition of additives can improve the drying speed and printing performance of the ink. The ink prepared by the invention has strong adhesion, bright ink color, abrasion resistance and scrubbing, and is easy to print. High environmental tolerance and long service life.

Description

technical field [0001] The invention relates to the field of printing inks, in particular to a high-gloss amino resin printing ink containing spherical silver powder. Background technique [0002] Printing ink is a common coloring material for printed products. It is mainly composed of pigments, binders, fillers and other components. It is a kind of colored paste-like adhesive with a certain degree of fluidity. In order to obtain a satisfactory printing effect, there are certain requirements for the color, printing adaptability, and drying speed of the ink during actual use. At the same time, it must have the characteristics of water resistance, light resistance, acid and alkali resistance, low toxicity and environmental protection according to the use environment. In the future, the development direction of printing inks must be towards the direction of low toxicity, fast drying, natural and diverse colors, and multi-functionality. Ink with better performance has disadvant...

Problems solved by technology

In order to obtain a satisfactory printing effect, there are certain requirements for the color, printing adaptability, and drying speed of the ink during actual use. At the same time, it must have the characteristics of water resistance, light resistance, acid and alkali resistance, low toxicity and environmental protection according to the use environment. In the future, the development direction of printing inks must be towards the direction of low toxicity, fast drying, natural and diverse colors, and multi-functionality. Ink with better performance has disadvantages such as high price. Therefore, it is necessary to improve the formula and process of printing ink and accelerate the transformation of the industry to achieve an efficient and environmentally friendly production mode.
