Green heat-preservation, heat-insulation and sound-absorption composite material and preparation method thereof
The invention belongs to the field of aerogel technology and organic fiber sound-absorbing composite materials, and relates to a green heat-preservation, heat-insulation and sound-absorbing composite material and a preparation method thereof. The green heat-preservation, heat-insulation and sound-absorbing composite material comprises an organic fiber felt and an aerogel material, the aerogel material is an aerogel material containing silicon aluminum or silicon aluminum titanium, and the mass ratio of the organic fiber felt to the aerogel material is 1: (2-12). The preparation method comprises the following steps of preparing a hydrophilic solvent with the surfactant concentration of 0.1-10%, spraying the hydrophilic solvent on the surface of the organic fiber felt, and drying the hydrophilic modified organic fiber felt at 80-150 DEG C after the hydrophilic solvent completely permeates into the organic fiber felt, and compounding a glass aqueous solution containing silicon-aluminum or silicon-aluminum-titanium components with the dried organic fiber felt to obtain a wet gel composite material, further putting the wet gel composite material into an ethanol solution for extraction and replacement, and drying the wet gel composite material after extraction and replacement to obtain a target product.
本发明属于气凝胶技术与有机纤维吸音复合材料领域，涉及一种绿色保温隔热吸音复合材料及其制备方法包括有机纤维毡和气凝胶材料，气凝胶材料为含有硅铝或硅铝钛的气凝胶材料,有机纤维毡和气凝胶材料质量比为1:2～12。其制备方法：配制表面活性剂浓度为0.1%‑10%的亲水性溶剂，亲水性溶剂喷射在有机纤维毡表面，待亲水性溶剂完全渗透有机纤维毡内部后，将亲水改性后的有机纤维毡放入80℃‑150℃中烘干；含有硅铝或硅铝钛成分的玻璃水溶液与烘干后的有机纤维毡复合，得到湿凝胶复合材料，进一步放入乙醇溶液中进行萃取置换，对萃取置换后的湿凝胶复合材料干燥，得到目标产品。
