preparation example Construction

[0045] According to one aspect of the present invention, a kind of preparation method of blue sunfast offset printing ink, described preparation method comprises the following steps:

[0046] First, fully stir the offset printing binder, lubricant, emulsifier and drier until they are all dissolved, and prepare a semi-finished product A; then, add the dry phthalocyanine blue powder, permanent violet and fillers to the semi-finished product A, and stir until uniformly dispersed , to make a semi-finished product B; finally, fully grind the semi-finished product B to reach the corresponding fineness of the ink, and obtain a blue light-fast offset printing ink.

[0047] The preparation method of the above-mentioned blue light-resistant offset printing ink of the present invention has the advantages of simple preparation and operation, low processing cost, no need of special processing equipment in the processing process, and convenient large-scale popularization and application.

Abstract

The invention provides blue sun-proof offset printing ink and a preparation method thereof, relating to the technical field of chemical printing ink. The blue sun-proof offset printing ink is mainly composed of an offset printing binder, a pigment, wax slurry, a lubricant, filler, an emulsifier and a drier, wherein the pigment is composed of phthalo blue dry powder and permanent violet. The phthalo blue dry powder is a phthalo blue organic pigment; and the permanent violet is a high-end organic pigment, is good in color intensity and has the advantages of heat resistance, permeation resistanceand good fastness to light, especially the pigment obtained by compounding the phthalo blue and the permanent violet in a mass ratio of (2-3):1 can achieve a better blue offset printing effect. The blue sun-proof offset printing ink obtained by virtue of the components has the advantages of strong sun-proof property, high printing speed and clear and natural blue pattern printing.

Description

technical field [0001] The invention relates to the technical field of chemical inks, in particular to a blue light-resistant offset printing ink and a preparation method thereof. Background technique [0002] With the advancement of the printing industry, the continuous improvement and improvement of printing technology and printing equipment, ink, as the most important printing material for information reproduction, is also undergoing constant changes. In recent years, offset printing ink has been favored by printing manufacturers at home and abroad for its unique advantages, such as fast and convenient plate making, low cost, high printing quality, wide range of paper use, and large printing quantity shrinkability, thus achieving rapid and extensive development. Then it occupies a dominant position in the international printing industry, and offset printing ink has also developed rapidly. [0003] Although offset printing inks have been greatly developed in recent years,...
