The invention provides a preparation method of a silver ant imitation wave-transparent bionic reflecting layer and an inflatable wave-transparent heat protection assembly. The method comprises the following steps of: constructing a PDMS bionic negative template by turning a silver ant biological template into a double mold, and smearing a glue solution on the PDMS bionic negative template to prepare the silver ant imitation wave-transparent bionic reflecting layer. The inflatable wave-transparent heat protection assembly comprises a silver ant imitation wave-transparent bionic reflecting layer, an inflatable layer and an infrared radiating layer from top to bottom; and the inflatable layer is inflated by an inflatable device when in rail, so that the whole assembly structure is adjusted toa certain filling state. According to the invention, the principle that the silver ant depends on a micro-nano fur layer structure to reflect sunlight is utilized to biomimetically copy the micro-nano structure on the surface of the silver ant, which reflects solar external heat flow in a wide band, so that the silver ant has good wave-transparent performance under the condition that the silver ant has the performance of preventing sunlight; the regulation of the filling state of the inflatable layer can adjust the tightening state of a heat-resistant microstructure on the surface, and play arole in micro-regulation of the equivalent thermal control parameters of a film layer structure, so that the temperature is uniform.
本发明提出了仿银蚁透波仿生反射层的制备方法及充气透波防热组件,该方法包括:通过银蚁生物模板翻模复模构筑PDMS仿生阴模板,在PDMS仿生阴模板上涂抹胶液,制备出仿银蚁透波仿生反射层。该充气透波防热组件从上至下包括:仿银蚁透波仿生反射层、充气层和红外散热层;所述充气层在轨的时候通过充气装置充气,使整个组件结构调节到一定的充填状态。本发明利用银蚁依靠微纳毛层结构反射太阳光的原理,将银蚁表面的宽频段反射太阳外热流的微纳结构仿生复制出来,使得兼具防太阳光的性能的情况下具备良好的透波性能;充气层的充填状态的调控可以调整表面防热微观结构的绷紧状态,对膜层结构的等效热控参数起到微观调控的作用,使温度具有均匀性。
