Foam reinforced silicon dioxide aerogel composite material and preparation method thereof
The invention relates to the technical field of composite materials, in particular to a foam reinforced silicon dioxide aerogel composite material and a preparation method thereof. The preparation method comprises the following steps: firstly, preparing fumed silica slurry, adding an opacifying agent, a silane coupling agent and the like, pouring the slurry into foam, filling foam pores, then carrying out a sol-gel process, and carrying out drying in various forms after gelatinization to obtain the aerogel composite material which can continue surface ceramization. The composite material is composed of foam, fumed silica, aerogel and an opacifying agent, and has excellent mechanical compressive strength, tensile strength, anti-vibration and anti-bending capability, durability, compressibility and fireproof and flame-retardant performance while keeping light weight, heat preservation and heat insulation performance and sound absorption and sound insulation performance. The aerogel composite material is good in flatness and stiffness and can be cut, carved and processed into a complex profiling structure, the splicing rough edge heat bridge effect of a traditional glass fiber aerogel material is reduced, and the heat insulation and energy saving efficiency is improved.
本发明复合材料技术领域，具体涉及一种泡沫增强二氧化硅气凝胶复合材料及其制备方法。本发明先配置气相二氧化硅浆料，添加遮光剂、硅烷偶联剂等，将浆料浇注到泡沫中，填充泡沫孔隙，然后进行溶胶‑凝胶过程，胶凝后进行多种形式干燥，获得气凝胶复合材料，还可继续表面陶瓷化。该复合材料由泡沫、气相二氧化硅、气凝胶、遮光剂组成，其在保持轻质化、保温隔热性能和吸声隔音性能的同时，具有优异的机抗压强度、抗拉强度、抗震动抗弯折能力、耐久性、可压缩性和防火阻燃性能。这种气凝胶复合材料平展度好，硬挺度好、可裁切雕刻加工成复杂的仿形结构，降低传统玻璃纤维气凝胶材料的拼接糙边热桥效应，提高隔热节能效率。
