Problems solved by technology
[0005] Even if water-based ink is used in children's packaging and printing products, health and safety cannot be guaranteed
Because it is easy to produce mold, bacteria and air pollution during use and storage, which will directly cause harm to children's bodies
At present, there are antibacterial materials (antibacterial textiles, antibacterial paper, etc.), but people's research on antibacterial inks is mainly to realize the sterilization function through bactericides, which are mainly used for packaging and printing of daily necessities at home, etc., but for children's deep contact As far as children's food, beverages, calligraphy and painting, and clothing are concerned, the use of fungicides is not conducive to children's health.

Abstract
The invention relates to an antibacterial water color ink for printed matters for packaging children products and a method for preparing the same. The method comprises the following steps: firstly, according to the stated weight percentage, evenly mixing and stirring part of a water soluble resin dispersoid, an amine stabilizer, a latent solvent, a bactericidal agent, deionized water and an antifoaming agent, then adding a pigment into the mixture, and dispersing the pigment at a rotating speed of between 500 and 1,200 rpm to prepare an even water soluble dispersed slurry; and secondly, pumping the water soluble dispersed slurry obtained in the step A into a sand mill by a pump, grinding the slurry until the fineness is less than or equal to 10 microns, then adding the remaining water soluble resin dispersoid, a wetting agent and a rheology modifier to the slurry, stirring the mixture until the materials are dispersed and mixed evenly, and adjusting the viscosity to prepare the antibacterial water color ink. The antibacterial water color ink prepared by the method has good adhesive force to various base materials or textiles, and the varnish thereof is full and has certain flexibility; besides, the antibacterial water color ink has low smell and ultra-low VOC without PAE and heavy metals, and has good antibacterial and antifungus functions.
Description
technical field [0001] The invention relates to a water-based ink, in particular to an antibacterial water-based ink used for packaging and printing products of children's products. [0002] The present invention also relates to a preparation method of the antibacterial water-based ink. Background technique [0003] The topic of environmental protection and health of children's products triggered by the "toy recall" incident has continued to heat up, and it has also made the public pay more attention to the quality and safety of food, beverages, medicines, clothing, calligraphy and painting, toys and other products and packaging that are related to children's health. At present, my country has not formulated and promulgated corresponding standards and regulations for children's products and packaging printing inks. In addition, the domestic packaging and printing ink market for children's products is immature, and the degree of specialization is not enough, which has contin...
