Abstract

The invention relates to an ink solvent, in particular to a green offset ink solvent. The offset ink solvent produced from monoacid of waste vegetable oil is polyalcohol monoester of the monoacid of the waste vegetable oil, which is generated by esterification of monoacid of the waste vegetable oil and polyalcohol in the presence of a catalyst; and accounted by percentage of total weight of the monoacid of the waste vegetable oil and the polyalcohol, the monoacid of the waste vegetable oil is 70 to 90 percent and the polyalcohol is 10 to 30 percent. Greasy ester compounds are used for the offset ink, so that the offset ink has good dilution and printability; and the greasy ester compounds can make the offset ink with macromolecular resin and organic pigment, the offset ink has good green safety and good printability, and is suitable for offset presses with high speed or low speed. The ink has no harm to environment and human bodies in the using process, is a green product absolutely, and has substantial market potential.

Description

technical field [0001] The invention relates to an ink solvent, in particular to a green offset printing ink solvent. Background technique [0002] At present, due to the increasing demand for greenness, the main solvent mineral oil of offset printing inks, due to the presence of natural dioxins in mineral oils, is increasingly questioned about greenness and restricted by the scope of use. Advanced offset printing ink manufacturers abroad are all In the study of replacing mineral oil with soybean oil and other vegetable oil products, soybean oil-based offset printing inks have been launched one after another. The purpose is to replace mineral oil with vegetable oil products, which is not only conducive to green hygiene but also beneficial to the regeneration of social resources. [0003] Large-scale domestic manufacturers of vegetable oil polyamide resins need to use a large amount of vegetable oil every year. The annual consumption is about 12,000 tons, and the annual outpu...
