Problems solved by technology

[0005] Most of the existing ink product production processes mainly use various resins as binders. On the one hand, the cost is high, and on the other hand, it is non-renewable and does not meet the concept of environmental protection. Therefore, it is necessary to provide an environmentally friendly and good performance vegetable soybean oil. Solvent ink production process is necessary

Abstract

The invention provides a method for preparing an epoxy-group-base conductive ink composition. Epoxy resin, coloring pigments, tributyl(1-ethoxy ethylene)tin, carbitol acetate and silver-coated copper powder are added into a reaction still by weight, stirring is conducted at the rotational speed of 200-500 rpm for 20-80 min, and grinding is conducted to obtain an intermediate product; then, soybean oil, water, wetting agents and N,N-diethylethanolamine are added, stirring is conducted at the rotational speed of 400-700 rpm for 30-90 min, filtering is conducted, and filtered emulsion is collected; defoaming agents and the intermediate product are added, stirring is conducted at the rotational speed of 200-600 rpm for 60-120 min, and the epoxy-group-based conductive ink composition is obtained.

Description

technical field [0001] The invention relates to a preparation method of an ink composition. Especially a preparation method of epoxy-based conductive ink composition. Background technique [0002] my country's ink industry has developed rapidly. Although the quality and quantity of my country's ink products have undergone tremendous changes, my country is still a developing country, and the per capita consumption of printed matter is still very low, only 5% of the per capita consumption of developed countries, and the use of ink is also very low In the next 5-10 years, my country's national economy will maintain rapid development, and the great development of ink is also obvious. [0003] CN103740173A discloses a preparation method of ink, based on the total weight of the ink, it is mainly composed of the following components in percentage: epoxy resin, 5-30%; polyester resin, 10-40%; defoaming Agent, 0.5-2%; wear-resistant emulsion, 5-20%; solvent, 40-60%. The ink of the...
