Abstract

The invention discloses an ink for a writing pen. The ink comprises the following components by weight percent: 10-20 percent of titanium dioxide, 25-65 percent of a water-based solvent, 10-18 percent of film-forming resin, 0.1-3 percent of a dispersing agent, 0.1-2 percent of a separating agent, 0.3-4 percent of a stripping agent, 0.3-3 percent of a film forming additive, 0.5-3 percent of a suspension additive, 5-10 percent of deionized water, 0.5-1 percent of a dampening additive, 0.5-1 percent of a leveling agent, 0.5-1 percent of an antifoam additive, 0.01-5 percent of a thickening agent, and 0-10 percent of a pigment. The method comprises the following steps: fully dispersing and uniformly mixing the components; putting into a grinding machine to be ground, thereby obtaining the ink for the writing pen. The ink has the characteristics of being nontoxic, harmless, environment-friendly and energy-saving; and a special baseplate is not required when the ink is used. Moreover, the ink has the characteristics of quick film forming, easy erasure, smooth writing, and tidy and clear writing, and is not limited by the air dryness.

Description

technical field [0001] The invention relates to an ink, in particular to an ink for a writing pen and a preparation method thereof. It can be widely used on various substrates such as teaching blackboards, stainless steel plates, glass plates, cement boards, paint boards, and PVC veneer boards. Background technique [0002] At present, the blackboard writing pens used in teaching are mainly based on lime-calcium chalk, and the fields such as government agencies, enterprises and institutions for daily office work, teaching, and training are mainly based on blackboard writing pens with benzene solvents; when using lime-calcium chalk, The dust produced contains a variety of substances that are harmful to humans. Inhalation into the air duct will cause discomfort in the nose, throat, throat, etc., and may cause lung cancer; the current whiteboard ink is mainly composed of pigments, resins, organic solvents, surfactants, and auxiliary materials. Composed of raw materials such as...
