Preparation method of high-strength nanopore calcium silicate thermal insulation material
The invention discloses a preparation method of a high-strength nanopore calcium silicate thermal insulation material, which comprises the following steps: S100, preparing a double-layer shell in a shell mold by adopting hard calcium silicate fiber, high-alumina cement and quartz powder; s200, calcium oxide, quartz powder and distilled water are adopted for preparing xonotlite, and xonotlite fiber slurry is obtained through treatment; s300, preparing tobermorite nanosheets from silicon dioxide, calcium oxide and distilled water; s400, treating the tobermorite nanosheet by using silicon dioxide aerogel and an organic silicon adhesive, so as to obtain silica gel tobermorite slurry; and S500, feeding the calcium metasilicate fiber slurry and the silica gel tobermorite slurry into a filter press mold to prepare a finished product. The high-strength shell is additionally arranged outside the nanopore calcium silicate material, so that deformation in the production process and the use process can be prevented, good heat conduction performance is achieved, the fiber structure of the product is changed into nanopores from micropores, and the heat preservation and heat insulation performance is greatly improved.
