Zusammenfassung: | The invention discloses white tipping paper with lasting, smooth and hydrophobic functions and a preparation method thereof, and environment-friendly white ink is prepared from the following raw materials in parts by weight: 5-8 parts of water-based hydroxyl acrylic emulsion, 2-3.5 parts of water-based acrylic acid butyric acid emulsion, 1.4-2.5 parts of water-based amino resin, 2-4 parts of polyvinyl acetate emulsion, 2-4 parts of organic silicon, 3-4 parts of titanium dioxide, 25-30 parts of ethanol and 15-20 parts of ethylene glycol. 31-40 parts of deionized water, 0.1-0.3 part of anti-settling agent, 0.1-0.3 part of wetting dispersant, a proper amount of PH regulator and 0.2-0.4 part of mildew preventive. According to the white ink, water-based acrylic emulsion serves as a main body, polyvinyl acetate emulsion, water-based amino resin, organic silicon and the like are added for blending modification, a cross-linking reaction occurs in the emulsion drying and film forming process, and an ink film with exce |
