Abstract

The invention provides washable biomaterial ink which comprises the following components in parts by weight: 1-30 parts of animal and vegetable oil, 1-30 parts of high molecular resin, 40-90 parts of solvent, 1-10 parts of catalyst, 0.1-10 parts of PH regulator, 1-10 parts of pigment, 1-10 parts of surfactant and 1-15 parts of auxiliary material. The washable biomaterial ink provided by the invention is healthy and environment-friendly, and has the biomaterial ink which is easy to wipe and can be repeatedly written. The principle of the application lies in that animal and vegetable oil in nature contains a large amount of chemical active groups, more stable epoxy oil can be obtained through oxidation, the oil has no harm to human bodies, and the oil and substances containing hydroxyl can generate ring-opening reaction under the action of a catalyst. The ink is prepared from natural animal and vegetable oil and nano resin under the action of a catalyst, and solves the problems that the ink is difficult to wipe and can not be repeatedly written on a chemical structure.

Description
