Soybean oil based offset printing ink containing nano aluminium sesquioxide and preparation method of soybean oil based offset printing ink

Abstract

Soybean oil based offset printing ink containing nano aluminium sesquioxide is prepared from the following raw materials in parts by weight: 0.7-0.9 part of methyl ethyl ketoxime, 5-6 parts of alkyd resin, 26-30 parts of rosin modified phenolic resin, 0.1-0.2 part of aluminum (2-ethylhexanoato-O)oxo-homopolymer, a proper amount of mineral oil, 60-65 parts of tung oil anhydride, 2-2.5 parts of tung oil anhydride, 0.1-0.2 part of tert-butyl hydroperoxide, 2-3 parts of glycidyl acrylate, 20-30 parts of a coloring agent, 1-2 parts of lanthanum 2-ethylhexanoate, 1.3-1.6 parts of methyl methacrylate, 2-3 parts of acrylic acid and 1-2 parts of nano aluminium sesquioxide. According to the offset printing ink, soybean oil is employed to replace most petroleum solvent in traditional printing ink so that the VOC is reduced below 15%; and by the use of nano aluminium sesquioxide, the offset printing ink can emit far infrared rays which can promote the offset printing ink to be dried, and meanwhile the wear resistance and cracking resistance of the offset printing ink are improved.

Description

technical field [0001] The invention relates to the field of offset printing inks, in particular to a soybean oil-based offset printing ink containing nano-alumina and a preparation method thereof. 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] Now, some ink c...
