Abstract

The invention relates to an environmental-protection ink for a hydraulic type water-based pen and a preparation method thereof, and belongs to the technical field of chemical product preparation. The environmental-protection ink comprises the components in parts by weight: 3.0-10.0 parts of a pigment, 3.0-8.0 parts of a resin, 2.0-5.0 parts of a dispersing agent, 2.0-10.0 parts of a moisturizing agent, and 90.0-67.0 parts of a solvent. The preparation method comprises the preparation steps: firstly adding the solvent into a pre-dispersing pot, successively adding the dispersing agent, the resin and the moisturizing agent according to the formula ratio with stirring until being completely dissolved evenly, finally, adding the pigment, fully stirring and mixing, then carrying out micro-grinding for 2-8 hours to make the pigment particle diameter reach a specific size, stopping grinding, and discharging. The ink prepared by the method has the advantages of bright-colored color, low viscosity, uniform ink discharging, smooth writing, stable quality, energy saving, environmental protection, convenient use, simple process and low cost, does not paste boards, and is easy to wipe.

Description

technical field [0001] The invention relates to an environmentally friendly ink and a preparation method thereof, more specifically to an environmentally friendly ink that does not stick to the board, is easy to wipe, and has good stability and a preparation method thereof, belonging to the technical field of chemical product preparation. Background technique [0002] For a long time, the pollution of chalk dust has been relatively large, and the majority of users have suffered from dust damage. In order to change this phenomenon, blackboard pen ink is a new product developed by the ink industry in recent years. It has the characteristics of dust-free and easy to wipe, and it is matched with special writing pens. , easy to carry, can erase handwriting within a certain period of time, without affecting continuous writing and visual reading, has the writing function of traditional ink, easy to write and erase, no dust pollution, widely used in office and academic exchanges, mee...
