High-transmittance infrared ray printing ink, preparation method thereof and IR display panel

The invention relates to the technical field of IR printing ink, in particular to high-transmittance infrared ink, a preparation method thereof and an IR display panel, and the high-transmittance infrared ink is prepared from the following raw materials in parts by weight: 20-40 parts of black ink, 15-20 parts of a diluent, 8-12 parts of a hardening agent, 2-4 parts of an additive and 1-5 parts of a surfactant. The transmittance of the high-transmittance infrared ray printing ink to infrared rays with the wavelength of 850 microns is larger than 82% +/-5%, the remote control distance is larger than 12 m, the high-transmittance infrared ray printing ink has good adhesive force, adhesion stability and hiding effect after film forming, and the visible light transmittance is smaller than 3%; the manufactured IR display panel is attractive in appearance, and the visible light transmittance is as low as possible while the high infrared transmittance is kept through silk-screen printing of the infrared ink in the li
