Novel dry-mixed thermal-insulation mortar and preparation method thereof
Disclosed novel dry-mixed thermal-insulation mortar is characterized by being prepared from the following raw materials in parts by weight: 3-4 parts of alumina magnesium metasilicate, 2-2.5 parts of sodium lignosulfonate, 2-3 parts of borax, 14-19 parts of red mud, 7-9 parts of nut shell activated carbon, 13-15 parts of rock wool leftover, 1-2 parts of polyester fiber, 2.5-4 parts of silica-gel powder, 18-21 parts of vitrified microsphere, 27-30 parts of Portland cement, 4-5 parts of expanded polyphenyl granule, and 8-10 parts of a synergist. By adding nut shell activated carbon, rock wool leftover and other fiber-rich compositions, the product toughness and strength are increased and also resource is saved; by adding alumina magnesium metasilicate, the product water retention performance and thixotropy are increased, and also the thermal-insulation effect of thermal-insulation mortar is improved; by adding the synergist prepared through a special technology, the product is capable of preventing water, moisture and worm damage, and because of the internally-contained water reducer, cement usage amount is reduced and construction performance is good. The product possesses good heat-insulation warm-keeping performance, plastering adhesion property, crack resistance and weatherability.
