Embodiment 1
[0022] 1. Add Portland cement (42.5 type) 650kg, Class I fly ash 250kg, saltlime 65kg, redispersed latex powder 12kg, 6~8mm polypropylene fiber 1.5kg, naphthalene series to the closed logistics convection mixer. 3.5kg of high-efficiency water reducer powder, 1.5kg of methyl cellulose ether and other raw materials are subjected to three-dimensional stirring, so that the raw materials are mixed evenly and the polypropylene fibers are fully dispersed, that is, a uniformly mixed dry powder is made.
[0023] 2. Transfer 140kg of the uniformly mixed dry powder to a biaxial two-way mixer, and then add B 1 10kg of grade flame-retardant EPS particles and 100kg of water were stirred evenly to prepare the slurry for preparing the composite reinforced waterproof and fireproof insulation board.
[0024] 3. The B 1 The particle size gradation of grade flame-retardant EPS particles is: Φ2mm EPS particles account for 20% of the total weight of the EPS particles, Φ3mm EPS particles account fo...
Embodiment 2
[0026] 1. In the closed logistics convection mixer, add 700kg of Portland cement (model 42.5), 220kg of grade I fly ash, 58kg of salt lime, 14kg of redispersed latex powder, 2.0kg of 6-8mm polypropylene fiber, naphthalene series 2.8 kg of high-efficiency water reducer powder, 2.2 kg of methyl cellulose ether and other raw materials are subjected to three-dimensional stirring, so that the raw materials are mixed evenly and the polypropylene fibers are fully dispersed, that is, a uniformly mixed dry powder is produced.
[0027] 2. Transport 160kg of the uniformly mixed dry powder to a biaxial two-way mixer, and then add B 1 11kg of grade flame-retardant EPS particles and 150kg of water were stirred evenly to prepare the slurry for preparing the composite reinforced waterproof and fireproof insulation board.
[0028] 3. The B 1 The particle size gradation of grade flame-retardant EPS particles is: Φ2mm EPS particles account for 15% of the total weight of the EPS particles, Φ3mm ...
Embodiment 3
[0030] 1. In the closed logistics convection mixer, add 750kg of Portland cement (model 42.5), 190kg of grade I fly ash, 58kg of salt lime, 16kg of redispersed latex powder, 2.5kg of 6-8mm polypropylene fiber, naphthalene series 3.5kg of high-efficiency water reducer powder, 2.6kg of methyl cellulose ether and other raw materials are subjected to three-dimensional agitation, so that the above-mentioned raw materials are mixed evenly and the polypropylene fibers are fully dispersed, that is, a uniformly mixed dry powder is made.
[0031] 2. Transport 180kg of the uniformly mixed dry powder to a biaxial two-way mixer, and then add B 1 14kg of grade flame-retardant EPS particles and 150kg of water were stirred evenly to prepare the slurry for preparing the composite reinforced waterproof and fireproof insulation board.
[0032] 3. The B 1 The particle size gradation of grade flame-retardant EPS particles is that Φ2mm EPS particles account for 10% of the total weight of the EPS p...
