Embodiment Construction
[0053] Examples see figure 1 As shown, this environmentally friendly super-hydrophobic vitrified microbead A-class fireproof composite thermal insulation board includes a thermal insulation layer, a mortar layer and a non-woven fabric. The super-hydrophobic vitrified bead plate is formed by extruding at low temperature, then extruded and shaped by a mold, and cooled and cut. Layer 2 is compounded; the thickness of the super-hydrophobic vitrified microbead plate 1 is 7 cm, and the thickness of the mortar layer 2 is 15 cm.
[0054] The super-hydrophobic vitrified microbeads are formed by impregnating vitrified microbeads with a two-component water-repellent agent, filtering, and drying. The two-component water-repellent agent is composed of monomethylsiloxane organic water repellent and The reactive polydimethylsiloxane aqueous emulsion is mixed at a weight ratio of 1:1.5 to prepare an aqueous solution with a concentration of 2‰.
[0055] The vitrified microbeads can adopt a v...
