Abstract

The invention discloses water-based plastic gravure ink and a preparation method thereof. The preparation method of the water-based plastic gravure ink comprises the following steps: uniformly stirring 10-15 parts by weight of acrylic resin liquid, 10-15 parts by weight of acrylic emulsion and 10-15 parts by weight of polyurethane dispersion through a reaction kettle at the temperature of 100-200DEG C to obtain a first mixed material; adding 20-30 parts by weight of water, 5-10 parts by weight of alcohol, 1-2 parts by weight of calcium carbonate and 0.5-1 part by weight of polyethylene wax into the first mixed material, and uniformly stirring at the temperature of 30-50 DEG C in a reaction kettle to obtain a second mixed material; adding 10-12 parts by weight of a pigment and 1-3 parts byweight of a dispersing agent into the second mixed material; dispersing, grinding and filtering to finally obtain the water-based plastic gravure ink; the water-based plastic gravure ink has the advantages of no VOC discharge, no harm to human bodies in the use process, no easy flammability or explosiveness in the preparation and use process, reduction of the fire safety hidden troubles and storage, wide application range and good effect.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a water-based plastic gravure printing ink and a preparation method thereof. Background technique [0002] Following the development of social culture, science and technology, and economy, the printing industry is developing at an unprecedented speed, and ink is the largest source of pollution in the printing industry. The world's ink production has reached 3.5 million tons, and the annual volatile organic compound (VOC) pollution caused by ink The discharge amount reaches more than 500,000 tons, which seriously pollutes the atmospheric environment and directly endangers human health. With the continuous improvement of people's awareness of environmental protection, green environmental protection has become the development theme of the 21st century. Therefore, the research, development and application of green packaging and printing materials with less harm...
