Abstract
The invention discloses a preparation method and an implementation method of a super-black extinction coating based on graphene and having excellent visible light absorptivity and infrared absorptivity. Aiming at the problems of high substrate selectivity, poor adhesion, poor aging resistance, undesirable visible-infrared light absorption effect and the like of the existing black paint, the nano-level and micron-level holes are formed by introducing the graphene and adjusting the types and the using amounts of the binder and the cross-linking agent so that the matrix resin shrinks during cross-linking and curing, and an excellent light trapping structure can be formed on the outer surface of the coating under the condition of not influencing the strength of the matrix, so that the reflectivity is further reduced, and the light absorption performance of the coating is optimized. The extinction coating prepared by the invention has the advantages of simple coating process, wide selectivity to a substrate, high production efficiency, good weather resistance and excellent adhesion. The absorption rate between 400-2300nm is 98.0-98.5%, and the product is suitable for optical components, baffles, light shields, inner walls of lens barrels, darkrooms and other systems and parts needing to eliminate stray light.
Description
Technical Field
The invention relates to the field of coating material preparation and application, in particular to a preparation method of an ultra-black extinction coating suitable for inhibiting and absorbing stray light in visible light and infrared bands.
Background
Stray light of the optical system refers to background radiation noise formed on a system detector by light rays in a non-imaging view field region reaching the image plane of the system. The stray light has a great influence on an optical system, so that the signal-to-noise ratio of a target is reduced, an observed target is imaged in a fuzzy mode, the contrast is reduced, the detection or identification capability of the whole system is affected, and in severe cases, a detected target signal is completely annihilated in a stray light background, the system cannot extract the target, or a false signal is formed on a system detector, so that the system detects a false target, and even the whole system fails.
With the progress of space optical technology, various large-aperture and long-focus optical devices come out in succession, optical systems with high sensitivity and low detection threshold are more and more, and various fixed star sensors, remote sensing observation devices and deep-space tiny weak-light target detectors are more and more interfered by stray light, so that the signal-to-noise ratio is reduced, the detection result is distorted, and national defense safety and commercial satellite development of China are seriously influenced.
No matter what kind of method is adopted for optical design, stray light cannot be completely eliminated, and particularly under the condition that the requirement of an optical system on the observation precision is higher and higher, the following disadvantages generally exist in the traditional physical and chemical black dyeing process such as an anodic oxidation black-out method, a multi-arc ion black plating film method and an adsorption coloring method:
1. the requirement on the substrate is high in selectivity, and differentiated process equipment and flow need to be matched according to parts with different sizes, and the uniformity is difficult to guarantee;
2. the absorbance is not high, only 90-92% of visible light absorptivity can be achieved, and the reflectivity is as high as about 15% when the visible light absorptivity is incident at a large angle, so that the extinction of an optical element in a precise photoelectric instrument with strict requirements is difficult to meet;
3. the process is complex, the process operation is difficult to control, and the production cost is high;
4. all organic dyes have the characteristics of aging and fading, so that the dyed black surface is easy to discolor and has poor durability.
At present, a high-absorptivity coating is coated on the surface of a non-optical structural component (a light shield, a light blocking ring, a lens barrel and the like) of an optical system by adopting a spraying method, so that primary stray light entering the optical system outside a detection view field can be effectively absorbed. Meanwhile, secondary stray light after reflection is effectively absorbed, the signal-to-noise ratio of an image is improved, and the detection sensitivity of a low-light target is improved. However, the general extinction coating and the extinction paint have insufficient extinction capability, are used for extinction of photoelectric instruments, have unsatisfactory effect and are difficult to meet the technical requirements. According to the reports of related documents (Journal of Materials Chemistry C,2018,6, 8646-. The coating can be coated on the surfaces of most common materials by adopting a physical direct current magnetron sputtering technology, but the technology is limited by the complicated sputtering equipment, the requirement on the size and the shape of a substrate is high due to the need of a vacuum system and a high-voltage device, the deposition speed is low and is about 0.01-0.5 mu m/min, and the coating cannot be put into practical production application.
In addition, the black paint sold in the market has no existing domestic SB-3 and SB-3A (solar absorptivity α s is 0.94-0.96), or Japanese GT-2000 and GT-7II (solar absorptivity α s is 0.90-0.92), Russian AK-512 and AK-243 (solar absorptivity α s is 0.94-0.96), American Z-306 (solar absorptivity α s is 0.94-0.96), and the black paint has no critical light absorption capability, even if the black paint is manufactured by a large-angle extinction instrument, the manufacturing cost of the black paint is very high, and the black paint is not expensive.
