Abstract

The invention discloses erasable water-based paint ink for mark pens and a preparation method thereof. The erasable water-based paint ink comprises the following components in percentage by mass: 15-40% of water; 0.1-0.5% of a defoaming agent; 0.3-1% of a wetting dispersant; 5-15% of water-based acrylic resin; 5-15% of waterborne polyurethane resin; 30-80% of water-based color paste; 0.1%-0.3% ofa preservative; 3-6% of a humectant; 0.1-1% of an anti-settling agent; and 0.05-10% of other auxiliary agents, wherein the water-based polyurethane resin is water-based aliphatic polyether polyurethane resin. The erasable water-based paint ink for the mark pen can be erased by dry cloth after being used for writing on smooth surfaces such as glass and the like, and has the characteristics of strong covering power, good sun resistance, good water resistance and high drying speed; and the environment-friendly and non-toxic effects are realized, and the environment-friendly effect is realized onthe health of consumers.

Description

technical field [0001] The invention relates to the technical field of ink, in particular to an erasable marker pen water-based paint ink and a preparation method thereof. Background technique [0002] At present, the marker inks on the market are mainly divided into two types: erasable ink and non-erasable ink. The erasable ink mainly includes whiteboard pen ink, which can be easily erased after writing on a smooth surface. However, the covering ability and water resistance of the whiteboard pen ink are poor, and there are few color varieties (generally black, red, blue, and green), so the whiteboard pen can only be used for writing on a whiteboard, and the scope of use is narrow. [0003] The non-erasable ink mainly includes paint pen ink, which has good covering ability and stability, and has a wide range of applications. However, after the existing paint pen ink is written on a smooth surface such as glass, it cannot be erased without the aid of a solvent. Contents of...
