Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

As shown in fig. 1, 2 and 3, an embodiment of the present invention provides a building exterior wall thermal insulation decorative board, an insulation board 10 at an edge is fixed on a wall 20 through a metal corner brace, the insulation board 10 includes an insulation layer 11, a facing reinforcing layer 12 and a decorative layer 13, which are sequentially arranged from inside to outside, the facing reinforcing layer 12 includes two layers of facing mortar layers 121, and a mesh cloth reinforcing layer 122 is arranged between the two layers of facing mortar layers 121; the insulating layer is made of EPS polystyrene board or inorganic composite non-combustible polystyrene board or XPS extruded polystyrene board; the plastering mortar layer 121 is plastering mortar or light plastering mortar; the inorganic coating layer 131 and the protective film 132 are disposed on the surface of the decorative layer 13 at one time, and the protective film 132 may be a plastic film.

In the above embodiment, the plastering mortar layer 121 and the mesh fabric reinforcing layer 122 are arranged between the heat insulating layer 11 and the decorative layer 13, so that the manufacturing process is simple, the installation is convenient, the heat insulating layer 11 is prevented from being fixed outside by coating the calcium silicate plate, the material loss is reduced, and the weight is reduced; the mesh reinforcement layer 122 improves the strength of the surface-coated reinforcement layer 12, the inorganic coating layer 131 has a decorative effect on the decorative layer 13, and the protective film 132 has a protective effect on the inorganic coating layer 131.

The side surface, facing the wall body 20, of the heat insulation layer 11 is uniformly provided with a plurality of bonding mortar blocks 14, the bonding mortar blocks 14 are made of polymer bonding mortar, four sides of the side surface, facing the wall body 20, of the heat insulation layer 11 are provided with a circle of polymer bonding mortar, and the mounting and bonding are more stable; a sealing strip 15 is arranged between the adjacent heat insulation plates 10, and weather-proof sealant 16 is arranged in a gap at one side of the adjacent heat insulation plates 10, which is far away from the wall body 20; the sealing strip 15 is polyurethane foam rubber or a polyethylene rod, and the weather-resistant sealant 16 is elastic weather-resistant sealant.

In the embodiment, the heat-insulating layer 11 is bonded with the wall body 20 through the polymer bonding mortar, and the bonding mortar blocks 14 are uniformly distributed, so that the weight of the heat-insulating layer 10 is more uniform, the weight of the heat-insulating layer 10 is reduced, the air permeability between the heat-insulating layer 11 and the wall body 20 is better, the heat-insulating layer 11 and the wall body 20 are prevented from being too wet, and the mildew resistance is good; the sealing strip 15 fills and plays the guard action with the gap between the adjacent heated board 10, and weather-resistant sealed glue 16 plays the guard action to the adjacent heated board 10 outside, prevents that water from getting into in the gap between the heated board 10.
