Abstract

The invention provides UV-LED fluorescent ink and a preparation method thereof. The UV-LED fluorescent ink is prepared from, by weight, 32-50 parts of special functional group acrylate oligomer, 15-18 parts of self-curing polyester acrylate, 20-25 parts of caprolactone grafted hydroxyl acrylate, 5-10 parts of photoinitiator, 6-8 parts of efficient amine co-initiator, 1-3 parts of auxiliaries and 3-4 parts of fluorescent powder. The fluorescent powder is well dispersed in the resin to prepare the fluorescent paint, the printing stability of an ink system is improved, and the obtained ink is good in printing performance and good in fluorescent effect and has a good application prospect when applied to packaging ink.

Description

technical field [0001] The invention belongs to the technical field of UV-LED inks, and in particular relates to a UV-LED fluorescent ink and a preparation method thereof. Background technique [0002] Due to its environmental protection characteristics, UV-curable inks are especially suitable for packaging and printing products that require strict hygienic conditions such as tobacco, alcohol, food, beverages, medicines, and children's toys. With the progress of society and people's higher and higher requirements for the quality of printed matter, some of the existing UV-curable inks have fluorescent functions, but the existing fluorescent inks have problems such as poor stability and general weather resistance after long-term use, resulting in insufficient color. , Low attractiveness, can no longer meet the needs of consumers for UV-curable fluorescent inks. Therefore, the development of an ink with good fluorescent effect and good printing stability can greatly improve th...
