Embodiment 1
[0027] One-component inorganic thermal insulation mortar, its raw material components and weight content are as follows: cement 400, fly ash 200, sepiolite fiber 30, gypsum 10, expanded closed-cell perlite 400, redispersible latex powder 10, cellulose ether 2. 1000 parts of water.
[0028] The method for preparing a one-component inorganic thermal insulation mortar includes the following steps: firstly, cement, fly ash, sepiolite fiber, gypsum, redispersible latex powder and cellulose ether are put into a gravity-free mixer according to the required weight ratio. The stirring spindle stirs at the normal speed of 50 rpm, and the high-speed flying knife is started at 1440 rpm. After 6 minutes of stirring, the high-speed flying knife is stopped, and the speed of the stirring spindle is reduced to 30 rpm and then put into the well-measured gradation expansion closed cell Perlite, continue to mix for 2 minutes, the material can be unloaded. Use an open packaging machine to pack into d...
Embodiment 2
[0030] One-component inorganic thermal insulation mortar, its raw material components and weight content are as follows: cement 450, fly ash 150, sepiolite fiber 20, gypsum 15, expanded closed-cell perlite 420, redispersible latex powder 8, cellulose ether 2. 1100 parts of water.
[0031] The preparation method is the same as in Example 1.
Embodiment 3
[0033] One-component inorganic thermal insulation mortar, its raw material components and weight content are as follows: cement 500, fly ash 100, sepiolite fiber 10, gypsum 20, expanded closed-cell perlite 450, redispersible latex powder 5, cellulose ether 3. 1200 parts of water.
[0034] The preparation method is the same as in Example 1.
