Problems solved by technology

However, the metal effect pigment ink used to show special effects in traditional ink varieties does not yet have a mature industrial product supply market. The main reason is that the corrosion chemical reaction between the metal effect pigment and the slightly acidic component in the UV curing product affects the The storage stability of inks, especially in the application of UV screen printing inks, is a more serious problem. The storage time at room temperature does not exceed 3 months, which seriously affects the production and use of printing plants.

Embodiment Construction

[0034] In order to describe the content of the present invention more clearly and completely, the concept of the present invention will be described below in conjunction with specific embodiments.

[0035] According to the proportioning relationship in Table 1 to Table 9, add polyurethane acrylate resin, active diluent and dispersant to the reaction kettle in proportion, and then stir and disperse with a disc stirring paddle. The dispersion time is 20 to 30 minutes. The dispersion system The temperature is controlled between 20°C and 40°C.

[0036]Add active diluent, photoinitiator, defoamer, leveling agent, adhesion promoter and polymerization inhibitor in proportion, and then stir and disperse with disc stirring paddle. , and mix the mixture evenly to obtain the finished UV-curable screen printing metal ink, wherein the dispersion time is 30-60 minutes, and the temperature of the dispersion system is controlled at 20°C-40°C.

[0037] Among them, the polyurethane acrylate re...

Abstract

The invention belongs to the field of ultraviolet curing coating and ink application, and particularly relates to an ultraviolet curing silk-screen printing metal ink and a preparation method thereof.In order to solve the problems in the prior art, the invention provides a curing method for ultraviolet curing fluff paint (paint or ink) and a fluff paint coating (or ink layer) in the fields of woodware, metal, fiber, leather, plastic, glass, ceramic and the like. The preparation method of the ultraviolet curing fluff paint (coating / ink) is simple in process, short in preparation time and suitable for large-scale popularization.

Description

technical field [0001] The invention belongs to the field of application of ultraviolet curing inks, and in particular relates to an ultraviolet curing screen printing metal ink and its preparation method and application. Background technique [0002] The traditional infrared heat curing method of coating and printing has faced challenges. The long curing time, the problem of a large amount of organic solvents used in formula products, and the high energy consumption make it difficult for many manufacturers to increase the added value of products and expand coatings. The application range of packaging and printing, the higher curing temperature also limits the use of a considerable number of substrates, such as paper and plastics. There is an urgent need for a new curing solution that meets the environmental protection requirements in the new situation, and the UV curing solution has emerged as the times require. The industrial UV wavelength ranges from 200nm to 410nm as it...
