Problems solved by technology

However, due to the short wavelength of the UV radiation source, the shallow irradiation depth, and the strong covering ability of the white ink used, the curing effect is often not good during the UV curing process, and the problem of bottom powdering is prone to occur. At the same time, the use of UV radiation sources has radiation hazards and other safety issues

Abstract

The invention discloses flame-retardant visible light curing digital jet printing white ink for three-dimensional decorative pictures, wherein the components comprise: 1.5-2.5 parts of a visible lightfree radical initiator, 6-15 parts of a composite filler with functions of initiation assisting and flame retarding, 50-70 parts of acrylic acid-2-(2-ethoxyethoxy)ethyl ester, 8-15 parts of tri(2-hydroxyethyl)isocyanurate triacrylate, 5-10 parts of tripropylene glycol diacrylate, 0.3-0.8 part of a dispersing agent, and 0.5-1 part of a resin defoaming agent. According to the present invention, byusing the safe and reliable visible light curing technology, the problems of insufficient curing depth, easy powdering, radiation harm and the like of the existing UV curing white ink can be improved;and by selecting the filler component with the flame-retardant characteristic, the produced three-dimensional decorative picture meets the requirements of indoor decorative materials on flame retardance, such that the product has wide market application prospects.

Description

technical field [0001] The invention belongs to the field of decorative painting inks, and in particular relates to a flame-retardant visible light curing digital jet printing white ink applied to three-dimensional decorative paintings. Background technique [0002] With the continuous increase in the demand for home decoration, oil paintings are more and more used in home soft decoration because of their rich colors, delicate and lifelike pictures, and strong three-dimensional effect, and they have great development prospects in the home decoration market at home and abroad. . However, due to the unique creative techniques of oil painting, there is a huge technical bottleneck in the mass production of decorative paintings. The traditional mass production method mainly completes the mass production of decorative paintings by scanning the hand-painted works and then using digital printing, but it cannot achieve the three-dimensional effect and relief effect of hand-painted o...
