The invention belongs to the field of building materials, relates to a use of a nano-material in a building exterior wall heat-retaining
system and provides a nano-material-containing high-strength high-heat insulation exterior wall inorganic heat-retaining face
brick. The nano-material-containing high-strength high-heat insulation exterior wall inorganic heat-retaining face
brick is characterized in that nano-particles are used so that
compressive strength, tensile strength and
bonding strength are improved. The nano-material-containing high-strength high-heat insulation exterior wall inorganic heat-retaining face
brick is prepared by adding a nano-material having a nanoscale particle size into a mixed
system of
cement, an auxiliary gel material, a
polymer binder, an inorganic light heat-retaining material, fibers and water, uniformly mixing, carrying out pressing molding of the mixture, carrying out
organic polymer crosslinking and
cement hydration
drying, and carrying out waterproof layer
coating. The nano-material-containing high-strength high-heat insulation exterior wall inorganic heat-retaining face brick has the advantages of excellent
flame resistance, high
compressive strength, high tensile strength, high
bonding strength and good insulation effects.
