Problems solved by technology

Ammonium substances such as ammonia water and triethylamine are volatile and have a strong odor, which leads to the disadvantage of poor pH stability of the system
[0013] 3. Due to the good printing permeability of the applicable base paper, it affects the color brightness of the water-based ink, resulting in poor gloss of the water-based ink
[0014] Therefore, the current water-based ink still has the problems of poor water resistance, poor acid and alkali resistance, poor pH stability and poor gloss.

Abstract

The invention relates to a waterproof, acid-resistant and alkaline-resistant fluorescent water-based ink universally used on paper and plastics. The ink is composed of the following raw materials in parts by weight: 10-30 parts of organic pigment, 1-10 parts of inorganic ultraviolet fluorescent pigment, 1-10 parts of dispersing agent, 0.1-1.5 parts of defoaming agent, 20-50 parts of deionized water, 50-100 parts of self-crosslinked acrylic emulsion, 0.1-1 part of thickening agent and 1-10 parts of cosolvent. The organic and inorganic ultraviolet fluorescent pigments are wetted and dispersed by using the self-crosslinked acrylic emulsion and the super water-based dispersing agent with a block structure so as to be uniformly and stably dispersed in a water-based ink system; the tinting strength and adhesive force of the water-based ink are enhanced through a self-crosslinking reaction; inorganic nano magnesium lithium silicate is adopted for regulating the viscosity of the water-based ink and improving the water resistance and acid-base resistance of the water-based ink, so that the water-based ink has favorable printability, water resistance, acid-base resistance and glossiness, and the defects of poor water resistance, acid-base resistance, pH stability and glossiness of the water-based ink are overcome.

Description

technical field [0001] The invention relates to an ink, in particular to a general fluorescent water-based ink resistant to water, acid and alkali, paper and plastic and a preparation method thereof. Background technique [0002] Printing ink consists of pigments, binders, solvents and auxiliary agents. Among them, the organic solvent in the link material is particularly serious to the damage of human body. Organic solvents can dissolve many natural resins and synthetic resins, and are important components of various inks, but some of them can damage the human body and subcutaneous fat. Long-term contact will make the skin dry and rough. If it penetrates into the skin or blood vessels, it will endanger human health along with the blood. Blood cells and hematopoietic function. Although most of these solvents can be removed by drying, the remaining solvents will migrate into food and endanger the human body. If solvent-based inks are used to print cigarettes, alcohol, food,...
