Problems solved by technology

The traditional cold-setting black ink mainly uses rosin-modified phenolic resin as the binder. Since the rosin-modified phenolic resin contains phenol, methanol and other chemical substances, the ink emits phenolic gas molecules during use, which is not conducive to human health. In addition, traditional cold-setting Low-grade printing paper is used for solid ink printing. These low-grade printing papers have higher requirements for ink quality, especially for ink viscosity and adaptability of ink accumulation. However, high-quality inks are also expensive due to their Relatively high, which therefore limits the use of coldset inks
In addition, when the printing quantity is large, the traditional cold-setting ink is easy to drop the plate during the printing process, which affects the quality of the printed matter

Abstract

The invention relates to the technical field of cold-set black ink, in particular relates to environment-friendly cold-set black ink and a production process thereof. The environment-friendly cold-set black ink is prepared from the following components in percentage by weight: 20 percent to 35 percent of carbon black, 5 percent to 25 percent of rosin modified phenolic resin, 1 percent to 15 percent of petroleum resin, 15 percent to 45 percent of vegetable oil, 5 percent to 25 percent of mineral oil, 1 percent to 10 percent of alkyd resin, 1 percent to 25 percent of calcium carbonate, 1 percent to 25 percent of kaolin, and 1 percent to 5 percent of antidesiccant. The proportion of the petroleum resin, the calcium carbonate, and the kaolin in printing ink is improved, the production cost is reduced, due to the calcium carbonate and the kaolin, the solid-containing content of raw materials is improved, and the control of the petroleum resin to viscosity is improved, so that the ink has good ink piling adaptability. A kneader is used for dispersing the solid-containing content in the raw materials, the fineness of the solid-containing content is strictly controlled, and the adaptability of image weakening of the ink is enhanced.

Description

technical field [0001] The invention relates to the technical field of cold-setting ink, in particular to an environment-friendly cold-setting black ink and a production process thereof. Background technique [0002] Offset printing ink is currently the most widely used printing method in the printing industry. Among them, the cold-setting ink has a fast printing speed and can be dried quickly at room temperature without the need for a dryer. etc. favor. The traditional cold-setting black ink mainly uses rosin-modified phenolic resin as the binder. Since the rosin-modified phenolic resin contains phenol, methanol and other chemical substances, the ink emits phenolic gas molecules during use, which is not conducive to human health. In addition, traditional cold-setting Low-grade printing paper is used for solid ink printing. These low-grade printing papers have higher requirements for ink quality, especially for ink viscosity and adaptability of ink accumulation. However, hi...
