Preparation method of pre-oxidized fiber felt-silica aerogel thermal insulation composite material
The invention belongs to the technical field of aerogel, and particularly relates to a preparation method of a pre-oxidized fiber felt-silica aerogel thermal insulation composite material. The preparation method of a pre-oxidized fiber felt-silica aerogel thermal insulation composite material comprises the following steps: preparing a water glass-acid solution, performing compounding to obtain a pre-oxidized fiber felt-water glass-acid solution, and drying a wet gel composite material. According to the invention, the low-cost water glass and the pre-oxidized fiber felt are compounded to obtainthe thermal insulation composite material with excellent thermal insulation performance, and the scheme is easy for industrial production and has good economic benefits.
本发明属于气凝胶技术领域，具体是涉及到一种预氧化丝纤维毡‑硅气凝胶绝热复合材料的制备方法。一种预氧化丝纤维毡‑硅气凝胶绝热复合材料的制备方法，包括以下步骤：配制水玻璃‑酸溶液、预氧化丝毡‑水玻璃‑酸溶液复合、湿凝胶复合材料的干燥。本发明通过使用低成本的水玻璃与预氧化丝纤维毡进行复合，获得的隔热性能极好的绝热复合材料，该方案易于工业化生产，并具有较好的经济效益。
