Abstract

The invention discloses a method for preparing ink solvent by utilizing waste animal and plant grease, and the method is characterized in that waste animal and plant grease is used as raw materials, the waste animal and plant grease is firstly heated so as to dehydrate and remove the impurities, then the waste animal and plant grease has esterification reaction with alkyl alcohol to remove the acid under a high-temperature pressurizing condition and under the catalytic effect of the acidity catalyst, then decoloration is carried out, and decompression, distillation, deodorization and dehydration are carried out to obtain the pure esterified grease which can be used as the ink solvent. The pure esterified grease can substitute the pure plant grease to be used as the ink solvent, so that the production cost of ink can be reduced, and the reutilization of the resource can be realized. Meanwhile, fatty acid in the waste animal and plant grease is converted to aliphatic ester through the esterification reaction, so that the drying performance of the ink solvent can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of ink, and relates to a method for preparing ink solvents by using waste animal and vegetable oils. Specifically, the present invention uses waste animal and vegetable oils to obtain pure Esterified grease is a new type of environmentally friendly ink solvent. Background technique [0002] Under the influence of sustainable economic development, resource issues and environmental protection issues have received unprecedented attention. Green printing is adjusting and guiding the development of the global printing industry with its powerful influence. In recent years, environmentally friendly inks have begun to be used in packaging and printing of food, medicine, etc., but overall, their application range is still extremely limited. In order for the ink to meet the requirements of environmental protection, the composition should be changed first, that is, new inks should be prepared with environmentally frie...
