Abstract

The invention provides a water-based ink for negative ion decorative paper. Every 100 parts of the ink consist of the following components in parts by weight: 50-60 parts of negative ion color paste, 20-30 parts of a modified casein liquid, 0.5-2 parts of a thickening agent, 0.1-0.5 part of an antifoaming agent A, 1-3 parts of ethanediol A, 1-3 parts of alcohol, 0.1-0.5 part of a mildewproof agent A, and the balance of water A. According to the water-based ink, negative ions can be sustainably released to the air without additionally adding energy resources and the concentration of the negative ions in indoor air reaches the level of that in suburb and fields. The ink is fine and smooth, is not precipitated or layered, and has the characteristics of good storage stability, full coating and the like.

Description

(1) Technical field [0001] The invention relates to water-based ink and a preparation method thereof, in particular to a decorative paper printing water-based ink capable of releasing negative ions and a preparation method thereof. (2) Background technology [0002] Tourmaline is a boron-containing cyclic silicate mineral with additional anions, the main chemical composition is SiO 2 , Fe 2 o 3 , B 2 o 3 ,, A1 2 o 3 、Na 2 O, MgO, Li 2 O, MnO 2 Wait. The crystal structure of tourmaline is a trigonal crystal system, that is, a complex trigonal ring composed of silicon-oxygen tetrahedrons. Due to the special crystal structure, two highly charged atoms are obviously dislocated on the crystal lattice, thus causing one end of the crystal to be the positive pole of charge. , the other end is the negative pole of charge, and electrons never stop flowing from the negative pole to the positive pole, thus forming a current and an electrostatic field. In 1989, Japanese schola...
