Fireproof thermal insulation mortar and preparation method thereof
The invention discloses fireproof thermal insulation mortar and its preparation method. The fireproof thermal insulation mortar is composed of the following raw materials: cement, potsherd, glass fragments, wollastonite, modified fly ash, sand, agar powder, modified starch ether, hydroxy propyl methylcellulose ester, polyvinyl alcohol and an antifoaming agent. The preparation method comprises the following steps: raw materials which satisfy conditions are mixed; a corresponding amount of water is added under a certain condition; and the materials are stirred. In comparison with the prior art, the invention has advantages as follows: by optimizing ratio of the raw materials, the raw materials have a synergistic effect; the mortar has good weatherability and fire resistance; density and compactness of the mortar are raised; water absorption is less than or equal to 4%; the mortar has good thermal insulation effect and ageing resistance; construction is convenient; setting time can be controlled to 2-4 hours; and construction efficiency is raised.
