Method for making external wall thermal insulation board with fluorite slag

Abstract

The invention discloses a method for preparing an external wall heat preservation plate through fluorite slag. The method comprises the following steps: mixing and crushing 14-16 parts by weight of active packing, 5-8 parts by weight of basalt fibers, 20-30 parts by weight of the fluorite slag and 10-15 parts by weight of carbide slag, and before fine grinding, putting 10-12 parts by weight of fly ash and 3-5 parts by weight of modified rubber powder into a ball grinding machine for fine grinding; (2) putting a dry mixture subjected to fine grinding into stirring equipment, adding 22-30 parts by weight of water for full stirring, and adding 5-8 parts by weight of a hydrochloric acid solution with the concentration being 18-20 percent. By adopting an inorganic-organic combined mode, the defects that an existing organic external wall heat preservation material is combustible, an existing inorganic external wall heat preservation material is high in ratio and high in heat conduction coefficient, and the maintenance middle stage is long, energy consumption is high and the heat preservation effect is poor in a construction or manufacturing process are overcome.
