Problems solved by technology

However, because the UV curing system is initiated by ultraviolet light, the traditional UV curing technology has disadvantages such as low curing speed of the colored system, difficulty in curing deep layers and shadow areas of objects, and limited shape of the application substrate, which limits its application.

Embodiment Construction

[0026] In order to fully understand the technical content of the present invention, the technical solutions of the present invention will be further introduced and illustrated below in conjunction with specific embodiments.

[0027] (one)

[0028] Prepare the blue UV photothermal dual curing ceramic inkjet ink by weight parts shown in Table 1, the preparation method is as follows,

[0029] A) Preparation of color paste: Add leveling agent, defoamer, polymerization inhibitor, anti-sedimentation agent and dispersant to HEMA and HDDA mixture while stirring, mix evenly under high-speed stirring, and then slowly add blue ceramic colorant High-speed dispersion, so that the blue ceramic pigment is evenly dispersed to form a color paste;

[0030] B) Preparation of premixed solution: under high-speed stirring, add silane coupling agent to the color paste, after mixing evenly, slowly add polyurethane acrylate and epoxy acrylate, stir and mix thoroughly, adjust the speed of the high-spe...

Abstract

The invention discloses UV photo-thermal dual-curing ceramic ink-jet ink and a preparation method thereof and relates to the technical field of ceramic ink. The ceramic ink-jet ink comprises the following components in parts by weight: 10-30 parts of urethane acrylate, 10-45 parts of epoxy acrylate, 5-40 parts of monomer, 1-3 parts of photoinitiator, 0.8-3 parts of thermal initiator, 0.32-1.5 part of thermal accelerant, 2-18 parts of dispersant, 2-18 parts of silane coupling agent, 15-45 parts of ceramic pigment and 1-4 parts of auxiliary, wherein the monomer is one or a combination of more of low-viscosity acrylate with single functional group, acrylate with two functional groups and acrylate with three or more functional groups; and the ratio of the thermal initiator to the thermal accelerant is (2-2.5):1. In the invention, the ultraviolet curing and thermal curing technologies are combined, polymerization can be performed under ultraviolet irradiation before thermal curing, and complete curing in a shadow area is guaranteed; and by applying the ceramic ink-jet ink to ceramic production, a delicate and vivid stereoscopic decoration effect with a strong color effect can be realized.

Description

technical field [0001] The invention relates to the technical field of ceramic inks, in particular to a UV photothermal dual curing ceramic inkjet ink and a preparation method thereof. Background technique [0002] In recent years, ceramic inkjet technology has been widely used in the field of architectural ceramics. However, the common ceramic inks on the market are generally solvent-based inks, which require a large amount of organic solvents, which is not conducive to the health of production operators and pollutes the environment. With the gradual strengthening of people's environmental awareness and the gradual improvement of relevant laws and regulations, research and development of high-performance , Low-pollution or even pollution-free ceramic printing technology is an inevitable trend in the development of ceramic inkjet printing technology. On the other hand, since the surface of fired and vitrified tiles has no capillary pores, the solvent in the ceramic ink is d...
