Document Type and Number:
WIPO Patent Application WO/2020/140327
Kind Code:
A1
Abstract:
A heat insulation plate raw material composition, a heat insulation plate, and a production process for the heat insulation plate. The components in parts by weight of the heat insulation plate raw material composition comprise: 60-80 parts of a siliceous substance, 17-28 parts of a binder, 5-8 parts of polystyrene particles, and 20-60 parts of water, wherein the binder comprises calcium oxide and/or calcium hydroxide. The tensile strength of the prepared heat insulation plate is 0.2 MPa or above, the compressive strength is 0.3 MPa or above, the bending deformation is 4 mm or above, the heat conductivity coefficient is 0.055 W/(m•K) or below at 25°C, the volume water absorption rate is 5.5% or below, and the fireproof grade is non-combustible, i.e., being not lower than A2 grade.
