Abstract

A printing ink belongs to the technical field of an ink. The printing ink comprises the following components, by weight part, sodium alginate, glycerin, triglycol, urea, triethylene glycol monobutyl ether, a mildew inhibitor, polyurethane-modified epoxy resin, polyester resin, a polyether-modified organosilicon antifoaming agent, a nanometer alumina emulsion and cyclohexanone. Through adoption of components including solid epoxy resin, polyester resin and a wear-resisting emulsion, the printing ink is greatly improved in adhesion force and wear resistance, is good in chemical resistance, becomes fine, and is greatly saved in consumption during use. The ink is good in stability and effect, is clear, has no undissolved substance appeared, is long in retention period, and good in light, cold, acid and water resistance, thermal resistance and stability. The prepared ink-jet printing ink is good in quality of printed patterns, has no bleeding or deckle edges, doesn't block the printing head, and ensures uniform printing.

Description

Technical field [0001] The invention relates to a printing ink, belonging to the technical field of inks. Background technique [0002] The factors that affect the printing effect mainly include the following properties of ink: [0003] Viscosity and surface tension: Viscosity is the resistance of the liquid to flow, and the surface tension of the liquid is related to the ability to form droplets. Generally speaking, inkjet inks must have a low viscosity and high surface tension to ensure good flow performance and liquid Drop shape. [0004] pH value: represents the concept of liquid pH. The more acid the solution is, the lower the pH value is. On the contrary, the more alkaline the solution, the higher the pH value. To prevent the ink from corroding the nozzle, the PH value should generally be between 7-12. [0005] Conductivity: In the ink, the conductivity value is used to reflect the level of salt content. Generally speaking, the salt content should not exceed 0.5% to avoid the...
