Problems solved by technology

Although soybean ink has a good prospect for environmental protection, due to the characteristics of soybean oil itself, the development of soybean ink has brought certain difficulties. The main difficulties are: 1. The dryness of soybean ink; 2. Adjusting the ink properties of soybean ink , making it close to or even exceed traditional ink

Abstract

The invention provides a plant oil-based offset lithographic printing ink formula and a preparation method thereof. The plant oil-based offset lithographic printing ink formula comprises, by weight, 30-35 parts of soybean oil, 19-29 parts of tung oil, 2-5 parts of soya alkyd resin, 30-35 parts of rosin-modified phenolic resin, 2-6 parts of a dry conditioning agent, 2-5 parts of a gelling agent, 18-28 parts of a pigment, 5-10 parts of a filler, 7-7.5 parts of other auxiliary agents and 2-5 parts of a drier. The preparation method comprises 1, binder preparation, 2, accessory material addition, 3, printing ink rolling and 4, re-rolling. The plant oil-based offset lithographic printing ink formula has the advantages of good rheological performances, fast curing performances, passing performances, good glossiness and good stability and is especially suitable for newspaper and periodical printing.

Description

technical field [0001] The invention relates to the technical field, and more specifically relates to a vegetable oil-based offset lithographic ink formulation and a preparation method thereof. Background technique [0002] In traditional inks, it generally contains 30%-60% of petroleum-based mineral oils (organic solvents, containing aromatics). When printing, the drying of the ink needs to volatilize these mineral oils, which will release a large amount of organic solvents and cause serious air pollution. The global annual discharge of organic volatile pollutants caused by inks has reached hundreds of thousands of tons. These organic volatiles can form a more serious greenhouse effect than carbon dioxide, and will form oxides and photochemical smog under sunlight, seriously polluting the atmospheric environment. For printing workers, long-term exposure to high concentrations of organic volatiles will cause great damage to the human body, especially the nervous system. T...
