Problems solved by technology

As far as the printing process is concerned, even if the solvent has good solubility, 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
Due to the use of toxic raw materials in the prior art ingredients, it is very harmful to human health

Embodiment Construction

[0006] An environment-friendly solvent for preparing gravure printing ink provided by an embodiment of the present invention comprises the following components and mass ratios: 40% ethyl acetate, 40% n-propyl ester, 10% isopropanol and 10% ethanol.

[0007] Mix ethyl acetate, n-propyl ester, isopropanol and ethanol in a ratio of 4:1:1:1 and put them into a stirrer, stir at a temperature of 45-55 degrees at a low speed until completely blended to obtain a finished environmentally friendly solvent.

[0008] The environment-friendly solvent used for preparing the gravure printing ink described in the present invention is environment-friendly, free of benzene series and halogenated hydrocarbons. Since the solvent is mixed with various solvents, it forms a finer volatilization gradient than traditional solvents, and is suitable for all types of gravure printing inks. In addition to greatly enhancing the release of solvents, it is also more conducive to the ink transfer formed by di...

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...
