Abstract

The invention provides rock wool and a method for manufacturing and producing the same. The rock wool comprises a chemical component which is a SiO2-Al2O3-CaO-M mineral component in silicate, and the mineral components include silica fume Si3O9, gehetinite {NaK4[Al(AlSi)Si2O8]3((Cl, F, OH, CO3, SiO)-Ca(Mg)4[Al(AlSi)Si2O8]3(Cl, F, OH, CO3, SO4)}, and anorthite CaAl2Si6O16. The method comprises: fully mixing red mud, quicklime, ground silica, and coal ash; pressing the mixture after uniform stirring to prepare red mud spheres; air-drying the pressed red mud spheres and uniformly mixing the pressed red mud spheres with dolomite blocks and coke; collecting fibers which are sent from a fiber forming system and sprayed with an adhesive in a negative pressure manner through a wool collecting hub; allowing the fibers containing the adhesive to form cotton-shaped mineral wool under the action of blowing by a centrifugal machine and an air ring and air suction by a wool collecting machine; and performing treatment to form a rock wool product. Thermal insulation performance of the rock wool is that the thermal conductivity is normally in a range of 0.03-0.047 W/(moK), the combustion performance depends on how much flammable adhesive is there; and the sound insulation performance is better than conventional rock wool.
