Abstract

The invention discloses a production method for preparing an external wall fireproof thermal-insulation plate by using slag cotton. The production method comprises: (1) slag cotton raw material preparation, wherein blast furnace slag, graystone, fly ash, magnesium oxide, calcium oxide and wollastonite are mixed and melt into a liquid mixture; (2) fiber preparation, wherein the liquid mixture continuously flows into a centrifugal roller rotating at a high speed, and condenses into filamentous fibers under the centrifugal throwing and air cooling effect, and the fibers are subjected to collecting molding under the air blasting effect of an air blower; (3) thermal-insulation material raw material preparation, wherein 50-65% of the prepared slag cotton, 3-6% of polycrystalline zirconia fibers, 15-20% of desulfurized gypsum, 10-15% of fly ash, and 10-15% of 425# cement are adopted; (4) wet molding plate preparation; and (5) finished product preparation.

Description

technical field [0001] The invention relates to a production method of a building exterior wall fire-proof and heat-retaining material prepared from slag wool, in particular to a production method of a light-weight, energy-saving, environment-friendly, flame-retardant, fire-proof and heat-retaining building material product. Background technique [0002] Building exterior wall insulation materials are divided into inorganic substances and organic substances. Organic substances such as polyurethane and phenolic formaldehyde have good insulation effects, but low fire resistance; large shopping malls, hotels, apartments and other crowded areas are frequently reported all over the country, and the fires caused by them are mostly Caused by external wall insulation materials, it will cause great losses to national property and people's lives. Inorganic materials such as rock wool, cement mortar mixed with polystyrene particles, glass microspheres, or simple mixed materials have hi...
