Detailed Description

The following provides a further detailed description of the present invention with reference to specific embodiments, and fig. 1 shows a schematic structural diagram of a first embodiment of the heat-insulating decorative board for exterior walls of the present invention, which includes a board body 1. The plate body 1 is composed of a face brick 11 compounded from outside to inside, a bonding mortar layer 12, a foam plastic plate 13 and a reinforcing base layer 14. It is important to note here that the reinforcement matrix 14 includes a low-alkalinity cement matrix 143. Embedded within the low-alkali cement matrix 143 are reinforcing ribs 141, expanded perlite 142, and glass fibers 144 (as shown in fig. 3). The number of the reinforcing ribs 141 is set to be plural, and they are arranged in a criss-cross manner with each other. In this way, the face brick with the decoration function and the foam plastic plate with the heat preservation function are integrated into a whole, so that on one hand, the construction process flow is reduced, the construction period is greatly reduced, and the requirement on the operation skill of constructors is lowered; on the other hand, the curing time of partial mortar is advanced to the workshop production and manufacturing stage, so that the waiting period in the construction process is greatly reduced. More importantly, the reinforcing base layer 14 is additionally arranged, so that the overall structural strength of the external wall heat-insulation decorative plate is effectively ensured, and the external wall heat-insulation decorative plate is prevented from being broken in the running and construction processes.
