Embodiment 1

[0037] (1) Weigh the raw materials according to the formula shown in Table 1, then slowly add the additives dropwise into the solvent and stir for 5 minutes; then add pearlescent powder, titanium dioxide and matting powder in turn, and stir for 10 minutes; then add fluorescent whitening agent, stirred for 10 minutes; finally added the resin, stirred for 15 minutes to obtain a white ink, and obtained the ink composition S1 of this embodiment.

[0038] (2) Print the ink composition S1 on a transparent glass substrate with a thickness of 0.8 mm using a 300-mesh polyester screen with a thickness of 15 μm and a 75-degree (Shore hardness unit) glue blade, and then cure it at 150 ° C After 30 minutes, a first layer of coating with a thickness of 8 μm was formed on the surface of the transparent glass, and the obtained sample was designated as S10.

[0039] (3) On the surface of the first layer of S10, continue to screen-print Nippon Seiko's BMR-008-107C dark blue near-infrared light-...

Embodiment 2-4

[0041] Ink compositions S2-S4, samples S20-S40, and near-infrared anti-reflection materials S22-S44 were prepared in the same steps as in Example 1, except that the ratio of raw materials in step (1) is shown in Table 1.

[0042] Table 1

[0043]

[0044] Note: In the above table 1, the resin is epoxy acrylic resin; the solvent is a mixed solvent of ethylene glycol butyl ether and butyl acetate with a mass ratio of 3:2; the pearl powder is CQV R-901S, with an average particle size of 10 μm; titanium The white powder is TRONOX R 828; the matting powder is Degussa OK520; the fluorescent whitening agent is CibaOB.

Embodiment 5

[0046] Using the same ink composition S1 and the same steps as in Example 1 to prepare sample S50 and near-infrared anti-reflection material S55, the difference is that in step (2), the curing temperature is 145 ° C, and the curing time is 1 hour. The thickness of the first layer of coating is 10 μm; in step 3, the curing temperature is 160° C., the curing time is 30 minutes, and the thickness of the second layer of coating is 8 μm.

Abstract

The invention provides an ink composition, which contains pigments, resins, solvents and additives; the pigments include pearl powder, titanium dioxide, matting powder and fluorescent whitening agent, and the average particle diameter of the pearl powder is 8-12 μm . The invention also provides a method for forming a near-infrared light anti-reflection layer on the surface of a base material and a near-infrared light anti-reflection material obtained by the method. The ink composition provided by the present invention is white, and the near-infrared light anti-reflection material printed by using the white ink composition of the present invention has a transmittance of 0.1-5.2% for visible light and a transmittance of up to 43.6% for near-infrared light. -71.4%.

Description

technical field [0001] The invention belongs to the field of ink, and in particular relates to an ink composition, a method for forming a near-infrared light anti-reflection layer on the surface of a substrate, and a near-infrared light anti-reflection material prepared by the method. Background technique [0002] Near-infrared light refers to light with a wavelength of 700-1500nm. Near-infrared light transmission ink is widely used in the light-receiving window of remote control and the infrared light-receiving window area of ​​mobile phones. Its main function is to achieve high near-infrared light transmittance and minimize the transmission of visible light, that is, to ensure While transmitting the signal, the interference of visible light is avoided. In order to ensure low visible light transmittance and high near-infrared light transmittance, an ink layer that can absorb visible light and transmit near-infrared light is generally printed on the surface of the substrate...
