[0020] The utility model provides a vacuum insulation exterior wall thermal insulation cement wallboard, such as Figure 1 As shown, it includes a base wall layer 1, and a bonding layer 2 is fixedly connected to the top of the base wall layer 1. Since the base wall layer 1 is usually made of cement concrete, the bonding layer 2 is a mortar formed by uniformly mixing cement, quartz sand, polymer binder and various additives. The external wall insulation layer board is connected to the base wall layer 1 through the bonding layer 2. A mechanical fixing part 3 is fixedly connected to one side of the top of the base wall layer 1. The mechanical fixing part 3 is used to increase the stability of the external wall fixation. The bonding layer 2 is fixedly connected to the top of the composite insulation layer 4, and the composite insulation layer 4 is fixedly connected to the top of the first reinforcement layer 5. The top of the first reinforcement layer 5 is fixedly connected to the second reinforcement layer 6. A stone slab layer 7 is fixedly connected to the top of the second reinforcement layer 6. A plurality of partition joints 8 are equidistantly provided on the top of the stone slab layer 7. A decorative surface layer 9 is fixedly connected to the top surface of the stone slab layer 7. Both the stone slab layer 7 and the decorative surface layer 9 are made of natural stone to ensure a service life when exposed to the air for a long time. The partition joints 8 are used to prevent wall cracking and to avoid serious cracking of a large area of concrete base due to thermal expansion and contraction. An inlay strip 10 is fixedly connected to the inner cavity of the partition joint 8. The inlay strip 10 is made of aluminum alloy. The inlay strip 10 made of aluminum alloy ensures the overall aesthetics of the exterior wall while reducing deformation due to thermal expansion and contraction.
[0021] Further, such as Figure 2 As shown, the first reinforcement layer 5 includes a first mortar leveling layer 51, which is used to ensure the flatness of the connection surface and the stability of the subsequent connections of other board layers. A steel wire grid 52 is fixedly connected to the top of the first mortar leveling layer 51, and the outer wall is reinforced by the steel wire grid 52 to ensure the strength and performance of the outer wall. A first anti-cracking mortar protective layer 53 is fixedly connected to the top of the steel wire grid 52, and the steel wire grid 52 is protected by the first anti-cracking mortar protective layer 53 to avoid cracking.
[0022] Further, such as Figure 3As shown, the composite insulation layer 4 includes a vacuum insulation board 41, and the top of the vacuum insulation board 41 is fixedly connected with a polystyrene particle insulation layer 42, a polyurethane board 43, an extruded board 44, a polystyrene foam board 45 and a fireproof surface layer 46 in sequence from bottom to top.

A mechanical fastener 3 is added to ensure the firmness of the exterior wall installation, and then a first mortar leveling layer 51 is applied to the surface of the composite insulation layer 4, and the flatness of the connection surface is ensured by the first mortar leveling layer 51, and a steel wire mesh frame 52 is added inside to reinforce the exterior wall by the steel wire mesh frame 52 , to ensure the strength and performance of the exterior wall, then apply the first anti-cracking mortar protective layer 53 and the second mortar leveling layer 61, and protect the wire mesh frame 52 through the first anti-cracking mortar protective layer 53 to avoid cracking, and ensure the flatness of the connecting surface of the mesh cloth 62 through the second mortar leveling layer 61, and prevent the occurrence of cracks through the mesh cloth 62 and the second anti-cracking mortar protective layer 63. After the insulation layer is completed, the surface of the exterior wall is sorted through the stone slab layer 7 and the decorative surface layer 9. The stone slab layer 7 and the decorative surface layer 9 are both made of natural stone to ensure the service life of long-term exposure to the air, and prevent the wall from cracking through the partition joints 8, and avoid large-area concrete base surfaces from causing serious cracking due to thermal expansion and contraction.
