Problems solved by technology

[0007] However, the mineral oil system inks for offset printing textbooks and periodicals on the market not only contain a high proportion of mineral oil mass, resulting in higher VOC emissions, but also cause serious pollution to the environment, atmosphere, and ecology, and the PAH (more Cycloaromatic hydrocarbons), a strong carcinogen, cause greater harm to health

Abstract

The invention discloses vegetable oil-based textbook and periodical ink and a preparation process thereof, and relates to the technical field of printing ink. The ink is prepared from the following raw materials in parts by weight: 14.2 to 15.5 parts of an organic pigment, 23.4 to 28.2 parts of high-viscosity vegetable oil-based resin oil, 35.5 to 41.8 parts of low-viscosity soybean oil-based resin oil, 3.5 to 8.2 parts of a filler and 3.5 to 5.5 parts of an auxiliary agent, wherein the raw materials of the high-viscosity vegetable oil-based resin oil comprise a high-viscosity rosin modified phenolic resin and soybean oil, and the raw materials of the low-viscosity soybean oil-based resin oil comprise a low-viscosity rosin modified phenolic resin and soybean oil. The ink is low in cost, good in oil solubility and stable in performance, reduces waste discharge in various technological processes, reduces volatile organic compound components of the printing ink, reduces pollution to the atmospheric environment, reduces the cost of an ink formula, and is economical and practical.

Description

technical field [0001] The invention relates to the technical field of printing ink, in particular to a vegetable oil-based ink for textbooks and periodicals and a preparation process thereof. Background technique [0002] The environment has always been an issue that has attracted much attention in the world. Under the current situation of rising calls for "green environmental protection", the domestic printing and packaging industry has continuously improved its requirements for environmental protection. As an industry that will have a certain impact on the environment, it has also begun to pay attention to its own behavior and participate in environmental protection actions. Ink is one of the raw materials of printed products, and it has also started its own green road, and various types of environmentally friendly inks have emerged as the times require. The use of environmentally friendly inks has gradually become a fashion in the printing industry, and it has also beco...
