The invention discloses an ink printing paper box which comprises a box body, wherein a first printing layer is arranged outside the box body; a film layer is arranged on the first printing layer; a second printing layer formed by
printing ink is arranged on the film layer; the ink printing paper box has a better appearance; the
printing ink comprises 40-50 parts of a composite polyacrylate
emulsion, 40-50 parts of color paste, 0.2-0.5 part of a
defoamer, 0.4-0.8 part of a leveling agent, 0.1-1 part of a thickener, 0.5-2 parts of
fumed silica, 0.1-0.5 part of a
moisturizer, 1-5 parts of a pH
regulator and 5-10 parts of water; the polyacrylate
emulsion comprises the following components in parts by weight: 20-35 parts of an acrylic
monomer, 1-3 parts of 1-dodecanethiol, 1-5 parts of hydroxyethyl
acrylate, 1-10 parts of an emulsifier, 5-15 parts of
soybean oil, 0.1-0.5 part of a
phosphite ester, 0.5-1.5 parts of an initiator, 1-5 parts of a pH
regulator and 1-10 parts of deionized water.The invention further provides a production process of the
printing ink; and the ink has the characteristics of low
pollution, good storage performance, strong adhesion to PP, PE and other plastic substrates, and good printing effect.
