Water-based paint ink for valve type pen and preparation method of water-based paint ink

Abstract

The invention relates to the technical field of fine chemical engineering, and discloses a water-based paint ink for a valve type pen. The water-based paint ink is prepared from the following components in percentage by mass: 10 to 20% of water; 0.1 to 0.5% of a defoaming agent; 0.8-2% of a wetting dispersant; 15-25% of waterborne acrylic resin I; 5-10% of waterborne acrylic resin II; 20 to 50% ofa white water-based color paste; 0.1%-0.3% of a preservative; and 0.05-10% of other auxiliary agents. The water-based paint ink for the valve type pen can achieve various properties of existing solvent type paint pen ink, has the advantages of being high in drying speed after writing, good in weather resistance, good in adhesive force on various writing base materials and the like, is basically odorless, environment-friendly and non-toxic, and can meet the safety technical standards of European Union and America.

Description

technical field [0001] The invention relates to the technical field of fine chemicals, in particular to a water-based paint ink for a valve pen and a preparation method thereof. Background technique [0002] At present, the paint pens on the market are basically solvent-based, with various organic solvents as the main body. Users will experience dizziness, chest tightness, nausea and other discomfort symptoms when using them for a long time. And the existing paint pen has problems such as slow drying speed after writing, poor weather resistance, poor adhesion, and there is an urgent need to develop a water-based paint ink for a valve-type pen. Contents of the invention [0003] In view of the above-mentioned problems, the object of the present invention is to provide a water-based paint ink for a valve pen and a preparation method thereof. Compared with the traditional cotton core pen, the ink of the valve pen can achieve higher viscosity, so that it can get fuller lines ...
