description The invention belongs to the technical field of interference of infrared smoke screens, and mainly relates to a shielding smoke screen material and a preparation method thereof; the smoke screen material is one-way transparent between 780nm and 14.0 mu m of an infrared spectrum and is two-way nontransparent between 380nm and 780nm of a visible spectrum. According to the one-way transparent smoke screen material, silicon dioxide of a content of 20%-30% is used as a main interference chemical; a smoke generating agent of a content of 70%-80% is added into the silicon dioxide; the silicon dioxide is glassy-state silicon dioxide. The prepared one-way transparent smoke screen material is high in smoke and flame shielding performance and high in absorption on the visible spectrum, and can generate scattering particles with size of 10-100 mu m to form compound smoke screen cloud clusters; the one-way transparent smoke screen material adopts a glassy-state silicon dioxide material, so that the one-way transparent smo
