Abstract

The invention provides a palm oil-base offset printing ink containing no mineral oil. The offset printing ink comprises the following components in percentage by mass: 10 to 25 percent of pigment, 40 to 75 percent of binding material, 5 to 30 percent of palm oil, 5 to 30 percent of palm oil derivative and 0.1 to 5 percent of auxiliary agent, wherein the binding material comprises 10 to 50 percentof palm oil, 10 to 50 percent of palm oil derivative and 30 to 70 percent of rosin modified phenolic resin. The invention also provides a preparation method of the ink. The offset printing ink prepared by the method does not contain the mineral oil and has the characteristics of no toxicity, no irritating smell, no corrosion, no combustibility, high using safety, high concentration, high printingadaptability, high dilution, high emulsification resistance and the like. Compared with the domestic soybean oil, the offset printing ink is low in volatile organic compound (VOC) content.

Description

technical field [0001] The invention relates to the field of printing, in particular to an environment-friendly offset printing ink and its preparation. Background technique [0002] Offset printing ink is mainly a fluid coloring material composed of pigments, additives, polymers and solvents. Among them, the main solvents of offset printing ink are mineral oil and vegetable oil. The drying process of offset printing ink on paper is very complicated. We can understand that the ink is dried through the penetration of mineral oil and the oxidized conjunctiva of vegetable oil. [0003] Since the existence of offset printing ink, mineral oil has always been indispensable in offset printing ink. Usually, the content of mineral oil in common offset printing ink is 25%~45%. Mineral oil is a non-renewable resource extracted from petroleum, which contains aromatic hydrocarbons that are harmful to the human body. [0004] Printed materials can be seen everywhere in our life and wor...
