Description

Technical Field

[0001] The present invention relates to the technical field of engineering camouflage, and particularly relates to a camouflage protection material for a field gas station and a preparation method thereof. Background Art

[0002] Field gas stations generally use oil storage bags to temporarily store oil. Since crude oil gathering and transportation stations are often far from field gas stations, the crude oil stored in the crude oil gathering and transportation stations needs to be transported to the field gas stations by transport vehicles. When the transport vehicle arrives at the field gas station, the transport vehicle needs to stop in the surrounding area of the oil storage bag to complete the loading and unloading of crude oil.

[0003] And field gas stations generally need to ensure their safety through camouflage protection. One of the common protection methods for field gas stations is to coat a layer of camouflage paint on the outer rubber layer surface of the oil storage bag. However, this kind of camouflage paint can only protect the oil storage bag itself and cannot protect the parking area of the transport vehicle around the oil storage bag. Since the transport vehicle full of crude oil has a large self-weight, the parking area of the transport vehicle mostly uses concrete pouring, which makes the parking area have obvious difference characteristics from the surrounding environment where the field gas station is located and is extremely easy to be detected. Therefore, if the parking area cannot be camouflaged and protected, it will also greatly increase the exposure risk of the field gas station. Another common protection method for field gas stations is to use a camouflage net. Although the camouflage net can camouflage and cover the parking area, the protection effect of the camouflage net is single, and it can only achieve visible light camouflage and cannot deal with the detection of infrared light and radar waves. Therefore, the parking area will still face infrared and radar exposure risks, thereby increasing the exposure risk of the field gas station. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a camouflage protection material for a field gas station and a preparation method thereof. By arranging the camouflage protection material above the parking area of the outer gas station, radar, infrared and visible light camouflage can be achieved simultaneously, significantly reducing the exposure risk of the field gas station.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] The present invention provides a camouflage protection material for a field gas station, which successively includes a radar absorbing layer, an infrared-electromagnetic scattering regulation layer and an optical camouflage layer from bottom to top. The radar absorbing layer includes 4-10% absorbent and 90-96% concrete by mass percentage; the infrared-electromagnetic scattering regulation layer is composed of conductive fibers, expanded perlite and sand and gravel; the optical camouflage layer is a sand soil layer.

[0007] Preferably, the mass ratio of the conductive fibers, expanded perlite and sand and gravel is 1-3:5-10:300-350.

[0008] Preferably, the absorbent includes at least one of carbon black, graphite, carbon nanotubes, SiC, SiCN, or Si. 3 N 4 among others.

[0009] Preferably, the water-cement ratio of the concrete is 0.3 to 0.6, and the strength of the concrete is C40 or C50.

[0010] Preferably, the conductive fiber includes at least one of copper fiber, stainless steel fiber, carbon fiber, silver fiber, or gold fiber.

[0011] Preferably, the thickness of the radar absorbing layer is 40 to 60 mm, the thickness of the infrared-electromagnetic scattering regulation layer is 120 to 165 mm, and the thickness of the optical camouflage layer is 20 to 35 mm.

[0012] The present invention also provides a preparation method of a camouflage protection material for a field gas station, which is characterized by including the following steps:

[0013] S1. Weigh the absorbent and concrete in proportion, mix them, and stir evenly to obtain a slurry.

[0014] S2. Pour the slurry obtained in S1 into a prefabricated mold, stop pouring and cure it after pouring to a preset thickness, and obtain a radar absorbing layer after the curing ends.

[0015] S3. Weigh the conductive fiber, expanded perlite, and sand and gravel in proportion, mix them, and stir evenly to obtain a prefabricated material.

[0016] S4. Lay a preset thickness of the prefabricated material on the radar absorbing layer, and the prefabricated material laid on the radar absorbing layer forms an infrared-electromagnetic scattering regulation layer.

[0017] S5. Uniformly lay a preset thickness of sand and soil on the infrared-electromagnetic scattering regulation layer to obtain the camouflage protection material.

[0018] Preferably, in S1, the specific stirring process is as follows: first stir at a speed of 30 to 50 r / min for 60 to 120 min, then stir at a speed of 60 to 80 r / min for 120 to 300 min, and finally stir at a speed of 40 to 60 r / min for 30 to 60 min.

[0019] Preferably, in S2, the curing time is ≥ 3 days.

[0020] Preferably, in S3, the stirring speed is 300 to 500 r / min, and the stirring time is 40 to 60 min. Compared with the prior art, the beneficial effects of the present invention are:

[0021] (1) The radar absorbing layer of the present invention is prepared from concrete doped with absorbents. By adjusting the doping amount of the absorbents, the dielectric parameters of the radar absorbing layer can be adjusted, enabling the radar absorbing layer to have excellent wave absorption performance and achieving anti-radar camouflage protection. Since high-strength concrete is selected, the radar absorbing concrete layer has a large bearing capacity. When a transport vehicle parks on it for a long time, no cracking or other phenomena will occur, ensuring the long-term service life of the radar absorbing layer. Secondly, because concrete is a porous structure, the aqueous solution in the pores gradually freezes as the temperature decreases, and the thermal conductivity of ice is about 4 times that of water. Therefore, different water-cement ratios of concrete will cause the thermal conductivity of concrete to change with temperature. By adjusting the water-cement ratio of the concrete, the thermal conductivity of the radar absorbing layer is maintained between 0.35 and 0.55 W·m-1·K-1, and then the conductive heat of the radar absorbing layer can be adjusted, making the heat conduction between the radar absorbing layer and the background environment where the field gas station is located relatively low, achieving anti-infrared camouflage protection.

[0022] (2) The infrared-electromagnetic scattering regulation layer of the present invention is prepared from conductive fibers, expanded perlite and sand and gravel. The conductive fibers have a high dielectric constant. By adjusting the content of the conductive fibers, the probability of the conductive fibers approaching or separating from each other can be adjusted, so that the conductivity of the infrared-electromagnetic scattering regulation layer is enhanced or weakened, realizing the regulation of the dielectric constant and resistivity of the infrared-electromagnetic scattering regulation layer, and then realizing the regulation of the radar reflectivity, further strengthening the anti-radar camouflage protection effect. The bulk density of expanded perlite is light, with good heat preservation performance and certain strength. By adjusting the content of expanded perlite, the temperature of the infrared-electromagnetic scattering regulation layer can be adjusted, making the temperature difference between the infrared-electromagnetic scattering regulation layer and the background environment where the field gas station is located relatively small, and further reducing the radiation temperature difference between the infrared-electromagnetic scattering regulation layer and the background environment where the field gas station is located, strengthening the anti-infrared camouflage protection.

[0023] (3) The optical camouflage layer is the sand and soil collected from the background environment where the field gas station is located. Therefore, after it is laid on the infrared-electromagnetic scattering regulation layer, the camouflage protection material will have the same optical characteristics as the background environment, achieving the anti-optical camouflage effect.
