[0029] Example 1

[0030] The formula is shown in Table 1:

[0031] Table 1

[0032]

[0033]

[0034] Preparation:

[0035] (1) Mix all raw materials except pearlescent pigment and photoinitiator, stir and disperse to obtain screen ink binder;

[0036] (2) Add pearlescent pigment, stir and disperse;

[0037] (3) Add photoinitiator before printing, stir and disperse for 40 minutes, then the light-curable silk screen pearlescent ink suitable for different substrates can be obtained, the viscosity is 260mPa·s (25℃, flat plate, the shear rate is 300s -1 ).

[0038] The GBT 7707-2008 standard is used for testing, and it has good adhesion with PET, BOPP and other plastic substrates and paper. When printed with KBA-Giori's high-speed rotary screen printing machine, it has excellent printability, printing at 10,000 sheets per hour. It can be dried in time at a high speed, and the pearlescent effect of the printed product is obvious, the lines are clear, and the physical and chemical resistance ...

Abstract

The invention provides a photo-curing silk screen pearly-luster ink applicable to different printing substrates and a preparation method of the photo-curing silk screen pearly-luster ink. The ink is prepared from the following components in percentage by weight: 5-60% of polyurethane acrylate, 1-30% of acrylates pre-polymer, 1-20% of adhesive force accelerating resin capable of participating curing, 0-30% of monomer, 5-25% of pearly-luster pigment, 0-40% of a solvent and 2-15% of a light initiator. The photo-curing silk screen pearly-luster ink applicable to the different printing substrate disclosed by the invention can be suitable for the different printing substrates at the same time and comprises plastic substrates including paper, PET (Poly Ethylene Terephthalate), BOPP (Biaxially-oriented Polypropylene), PP (Propene Polymer), PE (Poly Ethylene) and the like, and metal substrates; an adhesive force between the photo-curing silk screen pearly-luster ink and the printed materials is good and the photo-curing silk screen pearly-luster ink has good flexibility and wear-resisting and scrape-resisting strength; the acid-resisting and alkali-resisting performance is excellent and the performance for resisting each type of solvent is good, so that the requirements on silk-screen printing can be met.

Description

technical field [0001] The invention relates to an ultraviolet light curing pearlescent screen ink and a preparation method thereof, which are used for high-speed rotary printing. Background technique [0002] In recent years, with the development of industrial technology, the application of screen printing technology in the field of anti-counterfeiting has developed rapidly. It has some obvious advantages, such as letterpress, gravure, lithography and other printing methods that are difficult to print. Printing materials and various products, All can be printed by screen printing, which is conducive to the full embodiment of the anti-counterfeiting effect, such as printing some pressure-sensitive optical inks and magnetic inks on the surface of flexible plastic films, paper and fabrics. As a printing method with special effects, pearlescent pigments can produce elegant, unique, soft and pleasing visual effects on the surface of printed matter by virtue of its unique pearl l...
