Abstract

The invention relates to an environment-friendly solvent suitable for gravure ink. The ink includes the following components by mass: 40% of ethyl acetate, 40% of n-propyl, 10% of isopropanol and 10% of ethanol. With the temperature controlled at 44-45 degrees, the low-speed stirring the ethyl acetate, the n-propyl, the isopropanol, and the ethanol are stirred at a low speed, thus obtaining the environment-friendly solvent. The environment-friendly solvent prepared in the invention suitable for gravure ink is an environmental protection type intrinsically, and contains no benzene series and halogenated hydrocarbon. As the solvent is composed by mixing of various solvents, a more delicate volatilization gradient is formed compared with traditional solvents, so that the solvent is applicable to all kinds of gravure ink.

Description

technical field

[0001] The invention relates to a solvent for preparing ink, in particular to an environment-friendly solvent suitable for preparing gravure printing ink. Background technique

[0002] Gravure printing ink is often a mixture of various resins, and its solvent is also a corresponding mixed solvent. As far as the printing process is concerned, even if the solvent has good solvency, it may not have good printability; if the volatilization speed is too fast, it will easily cause web jamming; if the volatilization speed is too slow, it will easily cause poor drying. And because the ink solvent is a mixed solvent, if the volatilization amount of various solvents is inconsistent during the volatilization process, the volume ratio of each component will change (that is, the solvent formula changes), resulting in a change in the dissolution parameters, which may cause damage to the resin. The solvency decreases, thus affecting the printing effect. Because adopt toxi...
