The invention discloses a fire-resistant aerogel heat preservation and heat insulation coating, functional powder in the heat preservation and heat insulation coating is nanoscale silica aerogel powder, and a binder is composed of a mixture of potash water glass and silica sol. Meanwhile, the invention further provides a preparation method of the heat preservation and heat insulation coating. Thefire-resistant aerogel heat preservation and heat insulation coating provided by the invention has high sunlight reflection and middle and far infrared emission, and also has extremely low heat conduction performance; the thermal resistance is excellent, the flame resistance is good, and the durability is high; the finished product is pasty, so that dust pollution is avoided in the production process and the storage and transportation process, the product can be used immediately after being uncovered on site, on-site blending is not needed, and the quality of the product is controllable.
本发明公开了一种耐火型气凝胶保温绝热涂层，该保温绝热涂层中的功能粉体为纳米级硅气凝胶粉体，粘结剂由钾水玻璃和硅溶胶混合物构成。同时，本方案还提供了该保温绝热涂层的制备方法。本发明提供的耐火型气凝胶保温绝热涂层具有高太阳光反射和中远红外发射、同时具有极低的导热性能，在热阻性能优异的同时，耐燃性好，耐久性高，并且成品为膏状，生产过程和储运过程中避免粉尘污染，现场开盖即用，无需现场调配，质量可控。
