Problems solved by technology

In the process of manufacturing, printing and drying of solvent-based screen ink, due to the large amount of volatilization of solvents, it not only pollutes the environment, but also endangers the health of operators; Higher, and in the printing environment of strong ultraviolet radiation for a long time, it will also cause certain harm to the operator; water-based volatile dry screen ink has significant advantages such as safety, non-toxic and harmless, non-flammable and non-explosive, close to zero VOC, etc., but due to its In the high-speed printing process, a long drying tunnel is required, which is restricted by popularization

Abstract

The invention discloses an ultraviolet-cured rotary silk-screen printing ink with LED as a light source. The ultraviolet-cured rotary silk-screen printing ink comprises, by weight, 5 to 30 parts of pigment, 40 to 60 parts of radiation-cured resin, 1 to 15 parts of a photoinitiator, 5 to 20 parts of an active diluent, 0 to 10 parts of a solvent and 3 to 8 parts of an auxiliary agent. Electric energy consumed in curing of a silk-screen printing ink composition provided by the invention is about 1/4 of electric energy consumed by a common ultraviolet lamp; emission of CO2 is substantially reduced; and ozone is not generated. The silk-screen printing ink composition provided by the invention has viscosity of 50 to 350 mpa.s, overcomes problems in drying of a thick ink layer under irradiation of a low-power ultraviolet lamp and realizes instant drying under the rotary silk-screen printing condition of a high speed of 40 to 200 m/min; moreover, bonding between an ink film and a substrate is firm, and after curing, , each performance index (adhesion, friction resistance, chemical resistance and the like) of the printing ink accords with requirements on printing of securities.

Description

technical field [0001] The invention relates to an ultraviolet curing rotary screen ink and a preparation method thereof. Background technique [0002] As a printing with a wide range of applications, screen printing can be printed on various printing materials such as paper, plastic, glass, and electronic products. With the continuous development of printing equipment, high-speed rotary screen printing is becoming more and more popular. People value. In the process of manufacturing, printing and drying of solvent-based screen ink, due to the large amount of volatilization of solvents, it not only pollutes the environment, but also endangers the health of operators; Higher, and in the printing environment of strong ultraviolet radiation for a long time, it will also cause certain harm to the operator; water-based volatile dry screen ink has significant advantages such as safety, non-toxic and harmless, non-flammable and non-explosive, close to zero VOC, etc., but due to its...
