Abstract

The invention relates to a high-performance and easy-erasing ink and a preparation method thereof, and belongs to the technical field of chemical product preparation. The ink comprises, by weight, 2.0-5.0 parts of pigment, 3.0-7.0 parts of film forming agent, 2.0-6.0 parts of a dispersing agent, 4.0-8.0 parts of a moisturizing agent, 2.0-5.0 parts of xanthan gum, 1.0-3.0 parts of sodium chloride, 2.0-5.0 parts of polyvinyl alcohol, 1.0-3.0 parts of sacha inchi oil and 83.0-58.0 parts of a solvent. The preparation steps as below: first adding the solvent into a pre-dispersion pot, successively adding with stirring the dispersing agent, film forming agent, moisturizing agent, xanthan gum, chloride sodium, polyvinyl alcohol and sacha inchi oil according to the formula ratio, until complete homogeneous dissolution, and finally adding the pigment; and fully stirring for mixing, and then conducting micro-grinding for 2-8 h, so that the pigment particle diameter reaches a certain size, stopping grinding, and discharging. The ink prepared by the invention has bright color, low viscosity, even ink outflow, fluent writing, no adhesion to the board, stable quality and good performance, and is very easy to wipe, energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to a high-performance easy-to-wipe ink and a preparation method thereof, more specifically to a non-sticky, easy-to-wipe ink with 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, meetings and other occasions, Has gradually become a ...
