| titleOfInvention | A method for improving the oxidation resistance of a phenolic aerogel composite material and a modified phenolic aerogel composite material prepared therefrom |
| abstract | The invention relates to a method for improving the oxidation resistance of a phenolic aerogel composite material and a modified phenolic aerogel composite material prepared therefrom. The method is as follows: (1) preparing a precursor solution comprising a phenolic precursor, a catalyst and an organic solvent, and performing a sol-gel reaction after in-situ compounding of the precursor solution with a fiber product to obtain a phenolic wet gel composite material; ( 2) Airing the phenolic wet gel composite material at room temperature, and then drying to obtain a phenolic aerogel composite material; (3) compounding a certain depth of antioxidant precursor solution on the surface of the phenolic aerogel composite material, and then sequentially The air-drying step and the high-temperature drying step are used to prepare the antioxidant-modified phenolic aerogel composite material. The phenolic aerogel composite material prepared by the method of the invention has excellent oxidation resistance, low cost, short period and simple process. The phenolic aerogel prepared by the invention has the advantages of excellent anti-oxidation performance, good thermal insulation performance and the like, and excellent comprehensive performance. |
