Aluminum silicate fiber paper for aerogel felt and preparation method thereof
The invention discloses an aluminum silicate fiber paper for an aerogel felt. The aluminum silicate fiber paper is prepared from the following raw materials in parts by weight: 60-80 parts of aluminumsilicate fibers and 10-40 parts of glass powder. The preparation method comprises the following steps: washing aluminum silicate fibers with water to remove slag, uniformly mixing and stirring with glass powder to obtain slurry A, putting the slurry A into a mold, carrying out hot press molding, calcining the obtained blank, and cooling to obtain the aluminum silicate fiber paper for an aerogel felt. The aluminum silicate fiber paper is prepared by taking the glass powder as an adhesive; the contents of sodium oxide and potassium oxide in the glass powder are regulated and controlled; the melting temperature of the glass powder can be well controlled; the proper melting temperature enables the glass powder to infiltrate the softened aluminum silicate fibers, so that the problem of mutuallap joint of the fibers is solved, the fibers are uniformly combed and distributed, the temperature resistance of the fiber paper is improved, the pollution is reduced, the production period is shortened, and the method has an important use value for preparation and application of the fiber reinforced aerogel.
本发明公开了一种气凝胶毡用硅酸铝纤维纸，由以下重量份数的原料组成，60～80份硅酸铝纤维、10～40份玻璃粉。制备方法如下：将硅酸铝纤维水洗除渣后，与玻璃粉混合搅拌均匀，得到浆料A，将其置于模具中热压成型，得到的坯料进行煅烧处理，降温，得到气凝胶毡用硅酸铝纤维纸。本发明采用玻璃粉作为胶黏剂制备硅酸铝纤维纸，通过调控玻璃粉中含有的氧化钠、氧化钾的含量，可以很好的对玻璃粉的熔融温度进行控制，合适的熔融温度使其能浸润软化的硅酸铝纤维，从而解决纤维之间相互搭接的问题，保证项目的均匀梳理与分布，提高纤维纸的耐温性，降低了污染及生产周期，对纤维增强气凝胶的制备及应用具有重要的使用价值。
