Embodiment 1～14

[0074] This embodiment provides a series of infrared-transmitting black materials, and the dosage of each component in the formula is shown in Table 1 and Table 2.

[0075] The formula (part) of table 1 embodiment 1~8

[0076]

[0077]

[0078] The formula (part) of table 2 embodiment 9~14

[0079]

Embodiment 1

[0091] In Example 1, the surface color L value was about 23, and it was visually black. As the thickness increases, the a value of the light transmission color increases from -9.01 to 7.95, and the displayed light transmission color changes from green phase (a value is negative) to red phase (a value is positive); figure 1 It can be seen intuitively that the color changes greatly under the transmission condition. The thinnest position is 1.0mm and the light transmission color is green phase. As the thickness increases, the light transmission color is red phase.

Embodiment 2

[0092] In Example 2, the surface color L value was about 23, and it was visually black. As the thickness increases, the a value of the light-transmitting color increases from -8.92 to 7.62, and the displayed light-transmitting color changes from green phase (a value is negative) to red phase (a value is positive).

Abstract

The invention relates to an infrared-transmitting black material with the light-transmitting color changing along with the thickness and a preparation method and application of the infrared-transmitting black material. The infrared-transmitting black material includes a transparent resin, an infrared-transmitting colorant, and a dispersant. According to the infrared-transmitting black material provided by the invention, the surface color seen under visible light is black, and the near infrared transmittance is 85% or above; and the light-transmitting color gradually changes from green phase to red phase along with the change of the thickness, so that innovative application can be provided for product design, and the light-transmitting film can be popularized and applied to equipment shells needing infrared transmission signals, such as intelligent products and remote controllers.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an infrared-transmitting black material whose light-transmitting color changes with thickness, a preparation method and application thereof. Background technique [0002] Infrared optical system is widely used in the fields of scientific research, daily life, police and military industry because of its strong penetrating ability at night, strong ability to identify camouflage, passive acceptance of infrared radiation, good concealment, and insusceptibility to interference. It also gave birth to a broad near-infrared optical material market. With the promotion of the Internet of Things, AI, and 5G, the market application prospect of infrared optical materials will be broader, and its market demand in modified plastics will become more and more vigorous. For example, in smart life, smart lighting modules, daylighting modules, smart security modules, and smart...
