Myopia-preventing printing ink capable of effectively absorbing high-energy harmful blue light and preparation and spraying method thereof

Abstract

The invention relates to myopia-preventing printing ink capable of effectively absorbing high-energy harmful blue light and a preparation and spraying method thereof, wherein the myopia-preventing printing ink comprises an inorganic pigment, vegetable oil, calcium carbonate, acrylic resin and a defoaming agent, and is characterized in that the myopia-preventing printing ink comprises 45-55 parts of the inorganic pigment, 20-25 parts of the vegetable oil, 5-15 parts of the calcium carbonate, 5-10 parts of the acrylic resin and 2-2.5 parts of the defoaming agent. The myopia-preventing printing ink has the beneficial effects that the finished product ink is fine in particles, bright in color, strong in covering power, small in apparent specific volume, excellent in resistance and extremely high in chemical stability and high-temperature resistance, and high-energy harmful blue light with the wavelength ranging from 410 nm to 460 nm can be effectively absorbed after the paper is coated andprinted on site. The main wavelength of a printed finished product is in an accurate range of 572 + / -5 nm; the spectral point color has bright vision spectral light visual efficiency of 95% or more,and does not change along with different light intensities, so that frequent adjustment of eyes caused by light intensity change can be reduced, visual fatigue is relieved to the maximum extent, damage to vision is reduced, and the effects of protecting vision and preventing myopia are achieved.

Description

technical field [0001] The invention relates to the technical field of printing inks, in particular to an anti-myopia printing ink that effectively absorbs high-energy harmful blue light and a preparation and spraying method. Background technique [0002] Ink is a uniform mixture composed of colored bodies (such as pigments, dyes, etc.), linking materials, filling (filling) materials, additional materials, etc.; it can be printed and dried on the printed body; it is colored and has a certain flow. Degree of paste-like adhesive body. Therefore, color (hue), body (thickness, fluidity and other rheological properties) and drying performance are the three most important properties of ink. There are many types of them, and their physical properties are also different. Some are very thick and sticky; while others are quite thin. Some use vegetable oil as the linking material; some use resin and solvent or water as the linking material. These are determined according to the prin...

Problems solved by technology

[0004] The purpose of the present invention is to provide effective absorption of high-energy harmful blue light anti-myopia printing ink and its preparation and spraying method, to solve the lack of fineness of the existing printing ink proposed in the above background technology, resulting in rough particles affecting the use effect during the use of the finished product, And high reflection of high-energy harmful blue light with a wavelength of 410nm-460nm, and long-term viewing of blue with a wavelength of 410nm-460nm may cause vision degradation, visual fatigue, vision degradation or myopia technical problems
