Abstract

The invention discloses an aqueous colorful printing ink specially used for paper for daily use, and a preparation method thereof. The aqueous colorful printing ink specially used for paper for dailyuse is composed of, by weight, 5 to 10.5 parts of a binder, 0.4 to 6 parts of an edible natural pigment, 1 to 6 parts of powdery active carbon, and 40 to 100 parts of deionized water. According to thepreparation method, the edible natural pigment, and the binder are uniformly mixed with deionized water respectively, and then are mixed so as to obtain the aqueous colorful printing ink specially used for paper for daily use. Deionized water is taken as a solvent, so that using of toxic organic solvents is avoided, and aqueous printing ink safety is improved; the edible natural pigment is adopted, so that environment protection safe using requirements are satisfied; product preparation difficulty is not high, and the preparation method is suitable for on-site large batch production; the obtained product is excellent in permeability and bonding force, decolouring is not easily caused, and the aqueous colorful printing ink can be used for pattern printing, coating, spray coating, multilayer bonding, and the life of paper for daily use.

Description

technical field [0001] The invention belongs to the field of household paper manufacture and processing, and relates to a special water-based colorful ink for household paper and a preparation method thereof. Background technique [0002] At present, the safety of water-based ink technology for household paper has not received enough attention in China. Most of the household paper on the market uses ordinary water-based ink or chemically synthesized pigments, which are difficult to meet environmental protection, safety and edible standards. It affects people's health and limits the development of colored tissue paper. [0003] In particular, the new printing and embossed household paper has far stronger effects on the personalization and surface decoration of the product than the traditional pure white and natural color household paper. The new printed and embossed household paper uses edible materials , is a new concept attempt, but also a new attractive market opportunity...
