Problems solved by technology

[0002] At present, the commonly used thermal insulation measures for building walls are generally to apply a certain thickness of thermal insulation mortar or external thermal insulation boards on the ordinary masonry external walls, but this method is cumbersome to construct, with long construction periods and high costs, and the walls are prone to cracking and seepage. Leakage will seriously affect the insulation effect of the building
In addition, there is a thermal bridge problem in the energy-saving and thermal insulation external wall. The heat is lost through the thermal bridge, which increases the thermal insulation energy consumption of the building, and the safety performance cannot be the same as the building.

Embodiment 1

[0030] A rigid insulating composite board such as figure 1 As shown, the weight of the raw materials used is shown in Table 2, and the unit is kg / m 3 . The specific preparation method is as follows:

[0031] (1) Lay the metal mesh flat on the polystyrene board that has been coated with adhesive (commercially available construction adhesive) and fix it. At this time, there is a gap between the metal mesh and the polystyrene board or rock wool board. 1 ~ 2mm is the distance of the thickness of the adhesive to obtain the semi-finished product of the rigid thermal insulation composite board;

[0032] (2) Put the semi-finished product obtained in step (1) into the middle of the mold, mix the rest of the raw materials, extrude and pour it on and around the semi-finished product of the mold, vibrate and fix it, and then steam curing and air-drying to obtain rigidity Insulation synthetic board finished product.

Embodiment 2

[0034] A rigid insulating composite board used in the southern region, such as figure 2 As shown, the weight of the raw materials used is shown in Table 2, and the unit is kg / m 3 . The specific preparation method is as follows:

[0035] (1) Mix the raw materials except the metal mesh to obtain the heat preservation mixed material; wherein the polystyrene board needs to be pulverized into granules in advance;

[0036] (2) Lay the metal mesh in the mold, pour the thermal insulation mixture obtained in step (1) onto the metal mesh to make it integrated with the metal mesh, and then put a layer of metal mesh on it to fix Vibration forming, steam curing and natural air drying to obtain rigid thermal insulation composite board.

[0037] Wherein the thickness of the upper and lower metal mesh layers is 0.5-1 cm, and the thickness of the thermal insulation mixture between the upper and lower metal mesh layers is 3-5 cm. The thermal conductivity of the prepared rigid thermal insul...

Embodiment 3

[0039] A rigid insulation composite board used in northern regions, such as image 3 As shown, the weight of the raw materials used is shown in Table 2, and the unit is kg / m 3 . The specific preparation method is as follows:

[0040] (1) Mix the raw materials except the metal mesh to obtain the thermal insulation mixed material; the rock wool board needs to be crushed into granules in advance;

[0041] (2) Lay the metal mesh in the mold, pour the thermal insulation mixture obtained in step (1) onto the metal mesh to make it integrated with the metal mesh, and then put a layer of metal mesh on it to fix Vibration forming, steam curing and natural air drying to obtain rigid thermal insulation composite board.

[0042] Wherein the thickness of the upper and lower metal mesh layers is 0.5-1 cm, and the thickness of the thermal insulation mixture between the upper and lower metal mesh layers is 8-9 cm. The thermal conductivity of the prepared rigid thermal insulation composite ...
