A novel environment-friendly inorganic fireproof adhesive was prepared with sodium silicate, fumed silica, light calcium carbonate, aluminum hydroxide and magnesium hydroxide by high-speed mixing and ball milling. The bond strength, formaldehyde and VOC emissions, thermal properties and fire performance of such adhesive were investigated. The bond strength of the adhesive was increased with the adding of the fumed silica, which reached 1.8 MPa when the amount of fumed silica was 1.5 wt.%. Formaldehyde and VOC emissions of this adhesive were far lower than those of the requirements in Chinese standards. The combustion grade of this adhesive could achieve A1 and its smoke toxicity grade could achieve AQ 1 , which was the safest grade of flammability for building materials.
