Water-based ink as all-natural renewable resource and preparation method of water-based ink

Abstract

The invention belongs to the field of preparation of water-based ink, and particularly relates to water-based ink as an all-natural renewable resource and a preparation method of the water-based ink. The water-based ink comprises raw materials in percentage by weight as follows: 18% of a viscous liquid secreted by pine trees, 4% of active monomers, 7% of polar monomers, 60% of pure water, 0.2% of a nonionic surfactant, 0.2% of an anionic surfactant, 0.6% of an initiator, 3% of plant cellulose and 7% of an organic pigment. The viscous liquid secreted by the pine trees is subjected to graft polymerization modification, a hydrophilic group is introduced to a macromolecule chain, and the ink with stable performance can be prepared. A product does not contain an organic solvent, VOC (volatile organic compounds), 24 kinds of aromatic amine, formaldehyde and heavy metal elements, is free of organic solvent residues on a printed matter, is non-toxic, odorless, non-flammable and non-combustible, and is ecological, environment-friendly, energy-saving, low-carbon, healthy and safe.

Description

technical field [0001] The invention belongs to the field of preparation of water-based ink, and in particular relates to a pure natural renewable resource water-based ink and a preparation method thereof. Background technique [0002] With the rapid development of the printing industry, the demand and development of printing inks are increasing day by day. The production of traditional printing inks relies on a large amount of energy on earth. Petroleum system synthesis is used as the main film-forming component of the ink, and organic solvents, which are by-products of petroleum, are used as diluents. They are flammable and explosive products with high volatility and strong odor, causing serious pollution. For example, during the printing process, when the ink volatilizes and dries, these organic solvents release VOC volatile substances, which produce a strong odor and form a more serious greenhouse effect than carbon dioxide. Smog seriously pollutes the atmospheric envir...

Problems solved by technology

The production of traditional printing ink relies on a large amount of energy on the earth. The petroleum system is synthesized as the main film-forming component of the ink, and the petroleum by-product organic solvent is used as the diluent. It is volatile and has a strong smell. It is flammable and explosive, causing serious pollution.

For example, during the printing process, when the ink volatilizes and dries, these organic solvents release VOC volatile substances, which produce a strong odor and form a more serious greenhouse effect than carbon dioxide. Smog seriously pollutes the atmosphere and affects people's health and environmental quality

And when the VOC in the workshop gathers to a certain concentration in the air, when encountering an open flame or static electricity generated by machine operation, explosions and fires will occur, which seriously threaten life and property.
