Metamaterial structure heat insulation honeycomb aerogel and preparation method thereof
The invention discloses metamaterial structure heat insulation honeycomb aerogel and a preparation method thereof, and belongs to the technical field of aerogel preparation. The method comprises the following steps: designing and processing a core rod, taking the core rod as a mold, and weaving a fiber material hollow rope on the surface of the core rod; taking out the core rod, performing deformation treatment on the hollow rope, and performing gum dipping and preliminary curing to form a hollow pipe; bundling a large number of hollow pipes, and carrying out secondary bonding and curing treatment on the contact surfaces of the hollow pipes to obtain bundled hollow pipes; filling chopped fiber felts in the bundled hollow tubes to obtain honeycomb reinforced felts; silicon dioxide aerogel is prepared in the honeycomb reinforced felt in situ, and the two sides of a honeycomb opening are covered with plates to be sealed. The heat insulation honeycomb composite board with the metamaterial structure is excellent in comprehensive performance and easy to prepare and has obvious social benefits. The honeycomb superstructure is high in designability, and the honeycomb shape, the aperture and the spiral structure of the honeycomb superstructure can be selected according to requirements; the honeycomb superstructure composite felt is higher in strength and higher in compression resistance compared with a currently popular glass fiber reinforced heat insulation felt.
一种超材料结构隔热蜂窝气凝胶及其制备方法，属于气凝胶制备技术领域。所述方法为：设计与加工芯棒，以芯棒为模具，在其表面编织纤维材质空心绳；取出芯棒，将空心绳变形处理，并浸胶初步固化，形成空心管；将大量空心管进行集束，并对空心管间接触面进行二次粘接固化处理，得到集束空心管；在集束空心管管内填充短切纤维毡，得到蜂窝增强毡；在蜂窝增强毡内原位制备二氧化硅气凝胶，并在蜂窝口两侧覆板密封即可。本发明的超材料结构隔热蜂窝复合板综合性能优异、制备简单，具有明显的社会效益。该蜂窝超结构可设计性强，可根据需求选择蜂窝形状、孔径及其螺旋结构；该蜂窝超结构复合毡比目前流行的玻璃纤维增强隔热毡强度更高、抗压缩能力更强。
