The invention provides a lightweight shield shelter wallboard with an
infrared stealth function and a preparation method thereof. The shelter wallboard comprises a
honeycomb core material layer, a first
front panel layer and a second
front panel layer, wherein the first
front panel layer and the second front panel layer are arranged on the upper side and the lower side of the of
honeycomb core material layer; the surface of the
honeycomb core material layer, the surface of the first front panel layer and the surface of the second front panel layer are coated with
temperature control coatings correspondingly; and the first front panel layer and the second front panel layer each comprise a plurality of
layers of surface metallized
fiber fabrics. By arranging the
temperature control coatingsand the surface metallized
fiber fabrics in the shelter wallboard, the shelter wallboard has the
infrared stealth function and high shield performance. Compared with the prior art,
metal front panelsare replaced with the front panel
layers prepared from the surface metallized
fiber fabrics, and thus, the weight of the shelter wallboard is low. The experiment result shows that the electromagneticshielding effectiveness of the shield shelter wallboard is greater than 50 dB in 150 kHz to 1.5 GHz electromagnetic fields; and the surface
infrared radiation energy of the shield shelter wallboard islower than or equal to 100 W / m<2> at the surface temperature of 20-70 DEG C.
