Environment-friendly UV (ultraviolet) silk-screen printing anti-counterfeiting ink and preparation method thereof

Abstract

The invention relates to the technical field of ink and particularly relates to an environment-friendly UV (ultraviolet) silk-screen printing anti-counterfeiting ink. The environment-friendly UV silk-screen printing anti-counterfeiting ink comprises the following raw materials in parts by weight: 25-35 parts of polyurethane acrylate, 20-30 parts of polyester acrylate, 21-27 parts of acrylic acid ester functional monomer, 15-25 parts of fluorescent pigment powder, 0.5-1.5 parts of dispersant, 0.3-1 part of defoaming agent, 1-3 parts of flatting agent, 0.5-1.5 parts of light initiator and 0.3-1 part of adhesion promoter. The environment-friendly UV silk-screen printing anti-counterfeiting ink is bright in color, convenient to inspect and very good in stability, does not release harmful gas during the process of printing, and has less corrosion to equipment and a printing plate, thus meeting the requirement for environmental protection. The preparation method provided by the invention is simple to operate and low in production cost, and is beneficial to generalization and application.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to an environment-friendly UV screen printing anti-counterfeiting ink and a preparation method thereof. Background technique [0002] With the rapid development of my country's national economy, the prosperity of the printing and packaging industry has led to the rapid growth of the ink manufacturing industry, making my country rapidly rise to become one of the world's largest ink manufacturing countries in the past ten years. At present, the scale of the domestic ink industry is increasing by 10%. The above speed continues to grow rapidly. UV screen printing anti-counterfeiting ink is a new type of ink developed on the basis of traditional inks. It is widely used in outdoor advertising because of its unique printing adaptability, fast UV curing speed, good bending resistance, and good anti-counterfeiting performance. And the printing field of various packaging materials. [0003] For...

Problems solved by technology

[0003] For UV screen printing anti-counterfeiting ink, whether it has good stability is the key factor affecting its quality, but the existing UV screen printing anti-counterfeiting ink generally has shortcomings such as difficulty in dispersing inorganic fluorescent materials in the medium and poor stability, which affects its use effect; Traditional UV screen printing anti-counterfeiting inks use phenolic, alkyd and other component resins as the main binder, which will release harmful gases such as phenol and formaldehyde that are harmful to the human body during the printing process, which will not only cause great harm to the human body, but also It will also cause a series of problems such as short service life of printing equipment and environmental pollution.
