Embodiment Construction

[0015] The present invention is further described below in conjunction with embodiment.

[0016] The invention provides an ultra-low VOC water-based gravure silver ink, which is mixed with the following raw materials in weight percent:

[0017] All-solid water-based aluminum pigment 15-25%, deionized water 33-47%, ink emulsion 26-50%, leveling agent 0.5-1.5%, wetting agent 1-2%. Wherein, the all-solid water-based aluminum pigment is a water-based aluminum pigment in solid form, which is disclosed in related patent documents. Organic solvents are removed by vacuum heating, and the volatile organic compound (VOC) content is less than 1000ppm. The ink emulsion is a water-based acrylic emulsion or a modified water-based acrylic emulsion, and its residual monomer content is as low as 1000ppm. The leveling agent is polyether modified silicone, and its VOC content is lower than 1500ppm. Wetting agents are nonionic surfactants with a VOC content of less than 1500ppm.

Abstract

The invention discloses an ultralow-VOC aqueous gravure silver ink. The ultralow-VOC aqueous gravure silver ink is prepared through mixing 15-25 wt% of an all-solid aqueous aluminum pigment, 33-47 wt% of deionized water, 26-50 wt% of an aqueous ink emulsion, 0.5-1.5 wt% of a leveling agent and 1-2 wt% of a wetting agent. The invention also provides a preparation method of the ultralow-VOC aqueous gravure silver ink. The ultralow-VOC aqueous gravure silver ink has approximately zero VOC content, and is green and environmentally-friendly. The ultralow-VOC aqueous gravure silver ink has the advantages of excellent printing quality, saturated chroma, strong metal feeling and good covering power. The preparation method has the advantages of simple process, high production efficiency, environmental protection, no pollution, and low price and small size of used devices.

Description

technical field [0001] The invention belongs to the technical field of inks, and in particular relates to an ultra-low volatile organic compound (VOC) water-based gravure silver ink and a preparation method thereof. Background technique [0002] As the global environmental pollution and the destruction of the ecological environment intensify, people pay more and more attention to life, environment and human development. Water-based gravure silver ink has a unique metallic luster, and its color saturation is deeply loved by everyone. It is widely used in the packaging and printing fields of food, medicine, tobacco and alcohol, and is directly related to environmental protection and the health of human life. However, most of the water-based gravure silver inks currently used are alcohol-soluble fake water-based gravure silver inks that can be diluted with water, and a small part of water-based emulsion-type gravure silver inks. 5~8% alcohol or alcohol ether solvent. Therefor...
