The invention discloses a
nest type
thermal insulation board and belongs to the technical field of building external wall materials. A board body of the board is constituted by an assembling layer, a
resistor bridge layer, a
thermal insulation layer, a crack resisting layer and a decoration layer in sequence from the bottom
surface layer to the external
surface layer, and a preparation method comprises the steps of fabricating materials such as expanded
perlite,
cement, glass fibers and other accessory materials into different
slurry materials, making a structure provided with multiple cone-
tower-shaped nests out of the bottom surface, then continuing with the steps of formation, curing, trimming, steam curing,
drying and the like, and obtaining the
nest type
thermal insulation board. The
nest type thermal insulation board has the advantages that the dry surface of the thermal insulation board is low in density, the
thermal conductivity coefficient is low, the
compressive strength is high, the
combustion-resisting perform level is high, the board has the fireproof function, and the board has the advantages of being low in weight, heat
preservative, high in dimension stability, aging resistant,
frost resistant, convenient to install, simple to construct, beautiful in appearance and the like. In the construction process, the flowing
dust pollution caused by application of
powder materials is reduced, approximately 60% of construction time is saved in the construction cycle, the construction cost is greatly reduced, and the
energy consumption is saved in the
building construction in the real sense.
