Abstract：This paper presents an experimental research on thermosetting polystyrene insulation board made of Portland cement P·O52.5 blended with 23% of strength-enhancing and shrinkage-reducing agent. The casting process produces the materials with the following properties：the stripping time≤2 h，dry density≤180 kg/m3 and thermal conductivity≤0.053 W/（m·K），compressive strength ≥0.6 MPa，tensile strength≥0.14 MPa，flammability reaches class A. The pressing process produces the materials with the following properties：the demoulding time≤4 h，dry density≤150 kg/m3 and thermal conductivity ≤0.042 W/（m·K），compressive strength≥0.3 MPa，tensile strength ≥0.12 MPa，flammability reaches class A. The prepared insulation board complies with the requirement of G-type 060 and 050 in Chinese standard JG/T 536—2017.
