Detailed Description
The technical solutions in the embodiments of the present invention are described in detail below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
The embodiment of the invention relates to oily noctilucent printing ink which comprises the following components in percentage by weight: 5 to 20 percent of colorant; 15 to 35 percent of resin for printing ink; 20 to 60 percent of base oil; 5% -18% of rare earth luminescent material; 0.01% -0.05% of metal salt; 2-20% of auxiliary agent; and 2% -10% of varnish.
In particular, the base oil is selected from one or both of vegetable oil and mineral oil. Preferably, the base oil is 40% to 60%. For example, the base oil comprises 10% to 28% vegetable oil and 10% to 32% mineral oil.
The embodiment of the invention also relates to another oily noctilucent printing ink which comprises the following components in percentage by weight: 5 to 20 percent of colorant; 15 to 35 percent of resin for printing ink; 10-28% of vegetable oil; 10-32% of mineral oil; 5% -18% of rare earth luminescent material; 2-20% of auxiliary agent; and 2% -10% of varnish. Specifically, the mineral oil can be selected from one or more of model numbers 270#, 130#, 200#, D30, D40, D80, D100, D110 and D130. Preferably, the total amount of the vegetable oil and the mineral oil accounts for 40-60% of the weight of the ink.
The auxiliary agent comprises one or more of a filler, a dispersing agent, a viscosity regulator, an antioxidant, a diluent and an ink drying agent. Optionally, the filler is at least one of calcium carbonate and silica; optionally, the dispersant is selected from one or more of efficient hyper-dispersant AD-3200, ink dispersant SP-724 and ink dispersant LD-403; optionally, the viscosity regulator is viscosity regulator APAO; optionally, the antioxidant is selected from antioxidant 1010, antioxidant 168 or antioxidant 264; optionally, the diluent is selected from diluent 783, diluent 719, or diluent 788.
The applicant found in the research that the addition of a luminescent material capable of generating light to an oil-based ink can store light in the daytime and at nightAnd (4) intermittent luminescence. Such as rare earth activated alkaline earth aluminates, e.g. SrAl2O4:Eu2+、SrAL2O4:Eu2+.Dy3+And the like, which are photoluminescence materials that emit visible light under the excitation of a light source, store part of the obtained light energy, and slowly release the energy in the form of light after the excitation is stopped. The rare earth luminescent material can circularly store light and emit light for a long time, and the afterglow time of each time can reach several hours to 10 hours.
The luminescent material is commonly called luminescent powder (noctilucent powder), and is technically called long-phosphorescence phosphor, long-time luminescent material or long-afterglow luminescent material. The luminescent properties of different long afterglow luminescent materials are different. The color of the red-green tea is blue-green, blue-purple, yellow-green, blue or red. The peak wavelength of the emission spectrum is also 446-626nm respectively. For example: SrAl2O4:Eu.Dy3+The peak wavelength of the emission spectrum is 520nm, the afterglow time can reach hundreds of minutes or longer, and the afterglow intensity is 400mcd/m2(10min) and 60mcd/m2(60 min). Different luminescent powders have similar decay curves of afterglow brightness. The primary brightness is higher, after the excitation light source stops, the afterglow brightness rapidly decreases, and after 1min, the afterglow brightness is attenuated to about 40% of the primary brightness; after 10min, the brightness is attenuated to about 8% of the primary brightness; the decay of afterglow luminance becomes slow after 1 hr. Generally, the higher the brightness, the faster the decay changes. In particular, the addition of metal salts can further enhance the luminescent effect of rare earth luminescent materials, such as sodium chloride and aluminum chloride.
Based on the observation, the rare earth luminescent material is added into the oil-based ink, and the printed matter printed by using the ink has long afterglow luminescent performance. The printing product emits visible light under the irradiation of sunlight in the daytime, and part of the obtained light energy is stored. At night or in dark environment without light, the writing and the pattern on the printed matter can slowly release energy in a light form, and readers or users can also view books and works such as magazines, periodicals and the like under dark environment without light sources.
The printing product after the printing ink is added with different long afterglow rare earth luminescent materials can emit writing and patterns with different colors in a dark environment. The rare earth luminescent materials account for different proportions in the whole ink, and have different luminescent properties in the dark environment. With the increase of luminescent materials in the luminescent ink, the thickness of a film layer of the ink is increased, and the brightness of afterglow is increased; the latency is also correspondingly extended. However, if the luminescent material is excessively reduced in other components, the luminescence effect of the finished ink is also reduced.
