Waterless offset printing ink and preparation method thereof

Abstract

The invention discloses waterless offset printing ink and a preparation method thereof, and relates to the technical field of waterless offset printing ink. The invention solves the problems that the existing waterless offset printing ink is greatly influenced by the environment temperature in the actual printing process, and the viscosity of the ink is changed due to the small change of the temperature, so that the whole waterless offset printing ink has defects in use. The printing ink includes the following components in percentage by mass: 20-30% of pigment; 30%-40% of a resin binder; 5%-8% of filler; 5%-7% of an auxiliary agent; 2%-5% of a solvent; 1-5% of a diluent; 5-15% of modified polypropylene; and 5-10% of a photostabilizer. Herein, the pigments are organic pigments including a yellow pigment, a red pigment, a blue pigment and the like, including benzidine yellow, lithol red, 6B magenta, golden light red C, 2B permanent red, phthalocyanine blue and the like; the resin binder is composed of a composition of two or more of rosin modified phenolic resin, colloid rosin modified phenolic resin, linseed oil, soybean oil and mineral oil; and the filler is a copolymer of sodium acrylate and propanamide.

Description

technical field [0001] The invention relates to the technical field of waterless offset printing inks, in particular to waterless offset printing inks and a preparation method. Background technique [0002] Waterless offset printing ink is an ink used in waterless offset printing. Due to its use in waterless printing systems, it has higher viscosity, viscosity and rheological properties than traditional inks. Require. [0003] However, the existing waterless offset printing ink is greatly affected by the ambient temperature in the actual printing process, and a small change in temperature will cause a change in ink viscosity, resulting in insufficient use of the waterless offset printing ink as a whole; therefore, it does not meet the current requirements. Some demands, for which we have proposed an anhydrous offset printing ink and a preparation method. Contents of the invention [0004] The purpose of the present invention is to provide waterless offset printing ink an...
