A thin-plastered enhanced plaster layer 7 is provided on one side of the protective layer 2 close to the decorative surface layer 3, and a crack-resistant mortar layer 6 is provided on the other side of the thin-plastered enhanced plaster layer 7;

[0022] Specifically, as Figure 1 and Figure 2As shown in the figure, when in use, the interface mortar, also known as interface agent or polymer interface mortar, is mechanically and evenly mixed by cement, quartz sand, polymer binder and a variety of additives. It is mainly used to treat the connection part between the wall and the insulation layer and to improve the bonding performance of the surface of the base layer or insulation layer. The waterproof interface mortar is an interface mortar doped with waterproof agent to achieve the effect of waterproof and anti-seepage. At the same time, the anti-crack mortar layer 6 is mainly used to prevent cracks from appearing on the wall and the outer wall of the building. Its core components include cement, lime, sand and polymer. The polymer, as a kind of high molecular material, can enhance the bonding force and anti-crack performance of the mortar. In addition, the anti-crack mortar is also added with polymer emulsion and admixtures to make it have a certain toughness, so that the putty has better adhesion. After this kind of mortar dries, it can form a rough surface effect, ensuring that the wall does not crack, turn yellow or fall off, thus directly affecting the use effect of the wall insulation system. Through the mutual cooperation of the waterproof interface mortar layer 4 and the anti-crack mortar layer 6, the waterproof performance and compressive strength of the thin-plastered external wall insulation system can be effectively improved, thereby improving the practicability of the thin-plastered external wall insulation system and solving the problem that the waterproof performance and compressive strength of the thin-plastered external wall insulation system are relatively low, which will reduce the practicability of the thin-plastered external wall insulation system;

[0023] Among them: there is a thin-plaster enhanced plastering layer 7 provided. The thin-plaster enhanced plastering layer 7 is composed of cement-based or other inorganic materials, high molecular polymers and fillers for the plastering mortar. It is thinly plastered on the outer surface of the rock wool board / tape, and the alkali-resistant fiberglass mesh cloth is buried in the plastering mortar to form the thin-plaster enhanced plastering layer 7.

The cross-section connection between the first insulation layer 9 and the second special bonding mortar layer 10 is wavy. The cross-section connection between the second special bonding mortar layer 10 and the second insulation layer 11 is wavy. The half-wave length of the wavy shape at the cross-section connection between the first insulation layer 9 and the second special bonding mortar layer 10 is 5 mm. The half-wave length of the wavy shape at the cross-section connection between the second special bonding mortar layer 10 and the second insulation layer 11 is 5 mm. The first insulation layer 9 is laid by foam glass insulation boards, and the size of each foam glass insulation board is not more than 600 mm × 450 mm.

[0025] Specifically, such as Figure 1 、 Figure 2 andFigure 3 As shown, when in use, the first thermal insulation layer 9 is laid by foam glass thermal insulation boards, which can not only improve the thermal insulation performance of the thin plaster external wall thermal insulation system, but also improve the flame retardant performance of the thin plaster external wall thermal insulation system. And the second thermal insulation layer 11 is made of aerogel thermal insulation boards with a thickness of not less than 10 mm or aerogel thermal insulation boards, making the entire thin plaster external wall thermal insulation system have the advantages of Class A fire protection, good thermal insulation performance, small occupied area, and good weather resistance, thus further improving the thermal insulation performance of the thin plaster external wall thermal insulation system. Through double-layer thermal insulation, it can better meet the daily thermal insulation needs, thereby improving the thermal insulation effect, and solving the problem that only one thermal insulation layer is used for thermal insulation, which cannot well meet the daily thermal insulation needs and has a poor thermal insulation effect.

[0026] Working principle: In this application, the first thermal insulation layer 9 is laid by foam glass thermal insulation boards, which can not only improve the thermal insulation performance of the thin plaster external wall thermal insulation system, but also improve the flame retardant performance of the thin plaster external wall thermal insulation system. And the second thermal insulation layer 11 is made of aerogel thermal insulation boards with a thickness of not less than 10 mm or aerogel thermal insulation boards, making the entire thin plaster external wall thermal insulation system have the advantages of Class A fire protection, good thermal insulation performance, small occupied area, and good weather resistance, thus further improving the thermal insulation performance of the thin plaster external wall thermal insulation system. Through double-layer thermal insulation, it can better meet the daily thermal insulation needs, thereby improving the thermal insulation effect. Secondly, the waterproof interface mortar is an interface mortar doped with a waterproof agent to achieve the effect of waterproof and anti-seepage. At the same time, the anti-crack mortar layer 6 is mainly used to prevent cracks from appearing on the wall and the outer wall of the building. Its core components include cement, lime, sand and polymer. The polymer, as a high molecular material, can enhance the bonding force and anti-crack performance of the mortar. Through the mutual cooperation of the waterproof interface mortar layer 4 and the anti-crack mortar layer 6, the waterproof performance and compressive strength of the thin plaster external wall thermal insulation system can be effectively improved, thereby improving the practicability of the thin plaster external wall thermal insulation system.
