Silicon dioxide aerogel/glass fiber heat insulation composite board and preparation method thereof
The invention belongs to the field of thermal insulation materials, and discloses a silicon dioxide aerogel/glass fiber thermal insulation composite board and a preparation method thereof. According to the preparation method disclosed by the invention, the SiO2 aerogel is prepared by taking tetraethoxysilane TEOS and water glass as common silicon sources, so that the production cost of the aerogel is reduced, and meanwhile, the prepared glass fiber reinforced SiO2 aerogel composite board has relatively low density and heat transfer coefficient and also has certain mechanical properties. In addition, the method is simple in preparation flow and process, can meet the production and processing of large-size composite boards, and has the application prospect of large-scale industrial production.
本发明属于保温隔热材料领域，公开了一种二氧化硅气凝胶/玻璃纤维保温隔热复合板及制备方法。本发明以正硅酸乙酯TEOS和水玻璃作为共同硅源制备SiO2气凝胶，在降低气凝胶生产成本的同时，保证了制备出的玻璃纤维增强SiO2气凝胶复合板具有较低的密度和传热系数，同时具有一定的力学性能。此外，该方法制备流程及工艺简单，可满足大尺寸复合板的生产加工，具备大规模工业化生产的应用前景。
