Problems solved by technology

In the prior art, near-infrared-absorbing materials are often used to eliminate the light and radiation emitted by the lighting system in the equipment. However, with the development of lighting technology, the lighting system used in the equipment has gradually changed from the previous technology with high heat production to low heat production. development so that the lighting system within the device readily emits mid-infrared or far-infrared light or radiation

Abstract

The invention belongs to the field of optical materials, and discloses a composite material for absorbing mid-infrared and far-infrared, a preparation method and application thereof. The composite material is mainly prepared from the following raw materials: resin, graphite, carbon nanotubes, a filler, a resin curing agent and a solvent, wherein the raw materials also comprise nano silicon dioxide, fullerene or fullerene derivatives. According to the composite material, due to the use of the carbon nanotubes, the graphite and the resin, the transmittance of the composite material to mid-infrared rays does not exceed 0.18%, and the transmittance of the composite material to far-infrared rays does not exceed 0.30%, so that due to the transmittance of mid-infrared and far-infrared is low, theinfluence of light or radiation emitted by a lighting system in equipment on a night vision device can be prevented so as to ensure the normal work of the equipment such as the night vision device; and by introducing fullerene or fullerene derivatives, the transmission of visible light by the composite material can be further improved.

Description

technical field [0001] The invention belongs to the field of optical materials, in particular to a composite material absorbing mid-infrared and far-infrared and its preparation method and application. Background technique [0002] For all objects in nature, as long as its temperature is higher than the absolute temperature (-273°C), there will be irregular movement of molecules and atoms, and its surface will continuously radiate infrared rays. Infrared is an electromagnetic wave with a wavelength range of 760nm-1mm, which cannot be seen by human eyes. Infrared imaging equipment is to detect the infrared rays emitted by the surface of such objects that are invisible to the human eye. According to the division of infrared spectrum, the near-infrared wavelength range is 0.76-3μm, the mid-infrared is 3-40μm, and the far-infrared is 40-1000μm. The higher the temperature of the object, the shorter the infrared wavelength of the radiation. [0003] Night vision compatibility t...
