Description
Technical Field
The invention relates to a sun-proof waterproof ink and a preparation method thereof, belonging to the field of water-based ink for printing.
Background
Printing inks are homogeneous mixtures of color bodies (e.g., pigments, dyes, etc.), binders, solvents and other auxiliaries, which are used to form graphic information during the printing process. At present, environmental protection and green safety are more and more emphasized globally, and the treatment of the discharge problem of VOCs becomes the central importance of the treatment of the environmental pollution problem. The discharge amount of VOCs in the packaging and printing industry is increased year by year, and the discharge amount of VOCs in the packaging and printing industry in 2014 accounts for 17% of the total discharge amount of industrial sources. In 2015, in the next half year, a notice about volatile organic compound pollution discharge charging standard is issued, and the packaging and printing industry is seriously impacted due to higher VOCs discharge amount, so that the traditional packaging and printing industry faces transformation pressure.
The aqueous printing ink is one of printing inks, and water is used as a solvent or a dispersant. Almost no volatile organic compound is discharged, so the method has the green characteristics of environmental protection, no toxicity, energy conservation and emission reduction. In recent years, China also makes some regulations on the safety of food and medicine packaging, so that the status of ink-water printing in the printing market of China is promoted to rise year by year, the market share is gradually enlarged, and the prospect is good. Although the water-based ink has obvious advantages, the water-based ink produced in China at present generally has the defect of poor water resistance; meanwhile, some water-based ink adopting dyes and benzidine raw materials as color bodies has low temperature resistance and light fastness, so that the color fading problem is easily caused in the using process, and the defects also inhibit the rapid development and application of the water-based printing ink.
