Infrared light penetrating ink as well as preparation method and application thereof

The invention discloses infrared light penetrating ink as well as a preparation method and application thereof. The infrared light penetrating ink is prepared from the following components in percentage by weight: 60 to 70 percent of resin, 0.63 to 0.72 percent of black dye, 0.12 to 0.21 percent of red dye, 0.2 to 0.7 percent of waterborne polyurethane dispersion, 1.0 to 2.0 percent of curing agent and 28 to 40 percent of water. Preferably, the black dye is carbon black; and the red dye is 1, 2-dyhydroxyl-9, 10-anthraquinone. The preparation method comprises the step of mixing the raw materials. The infrared light penetrating ink can be used for pollution detection of glass or silicon wafers. By controlling the mass percent of the black dye and the red dye, stable low reflectivity and light transmittance in a visible light region can be achieved, high light transmittance in an infrared light region can be achieved, and the adhesive force to base materials such as glass is high. 本发明公开了一种红外光穿透油墨及其制备方法和应用。按照重量百分
