Problems solved by technology

Although this ink has excellent printability, good post-press processing performance, and fast drying, but due to (1) the relative toxicity of toluene, the residual solvent value of printed matter is high; (2) the thermal stability of chlorinated polypropylene is poor , in the process of production and storage, it is easy to release chlorine to form hydrogen chloride, which makes the ink highly acidic and severely corrodes the printing plate roller; (3) the organic volatiles produced by benzene-soluble ink can destroy the ozone layer, and The use process will also cause harm to the health and safety of the operators, and the residues left in the packaged products will cause a certain degree of pollution to the food in the package under certain conditions.

Abstract

The invention relates to a green and environment-friendly compound solvent for printing oil and a preparation method thereof, belonging to the technical field of organic mixed solvent. Dimethyl carbonate and diethyl carbonate are oxosynthesized by carbonyl, reaction products are respectively rectified and collected to obtain 90-94 DEG C fraction and 125-128 DEG C fraction, and dimethyl carbonate, diethyl carbonate, acetic ether, butyl acetate and cyclohexane are dispersedly regulated to be even in a certain volume ratio to obtain the product. The printing ink solvent is colourless and clear, non-benzene and non-ketone with short boiling range, low aromatic hydrocarbon content and good dissolving nature on resin, causes good fluidity of the printing ink, has good transitivity and rapid solvent release property, good high-temperature stability, excellent dot reproducibility and lustre performance, high stability in storage, is not easy to separate out of the printing ink, and can be used as a prinking oil solvent of food package.

Description

technical field [0001] The invention relates to a high-solubility polymer resin, which is a green and environment-friendly composite solvent for plastic printing ink, and belongs to the technical field of organic mixed solvents. Background technique [0002] With the development of economy and society, countries all over the world pay more and more attention to environmental pollution. The printing industry occupies an important position in the national economy. Colorful printed matter brings civilization to human beings and also causes environmental pollution. The development of the printing industry is closely related to the development of the ink industry. Ink is currently one of the largest sources of pollution in the printing industry, and the amount of volatile organic compound (VOC) pollution caused by ink has reached hundreds of thousands of tons every year. These organic volatiles mainly come from the solvent of the ink. [0003] With the improvement of living sta...
