Problems solved by technology

[0002] At present, the external wall insulation system commonly used in construction projects has certain defects in construction. The wall is easy to crack, the durability is not enough, and the insulation material does not meet the A-level material standard. Otherwise, it is easy to be used during construction and later. It is a fatal hazard of combustion, especially after the 11.15 incident in Shanghai, the fire protection requirements for wall insulation materials are getting higher and higher
At present, there are grade A products for thermal insulation that can metabolize inorganic glass wool in the market, such as rock wool board, but the thermal insulation performance of the rock wool insulation layer is poor, easy to be damp, deformed and peeled off, and the reinforcement technology is backward, which affects the thermal insulation and safety performance of the thermal insulation system.

Embodiment

[0024] Such as figure 1 As shown, a thermal insulation composite wallboard for external walls, from the inside to the outside, consists of a glue layer 1, an insulation layer 2, an interface agent layer 3, a plastering mortar layer 51, a glass fiber mesh cloth 6, and a plastering mortar layer 52 , finishing layer 7. The inner surface of the thermal insulation layer 2 is bonded to the wall by coating the adhesive mortar layer 1, the interface agent layer 3 is coated on the outer surface of the thermal insulation layer 2, and the inner surface of the glass fiber mesh cloth 6 is bonded by the plastering mortar layer 51 On the interface agent layer 3, the outer surface is bonded to the veneer layer 7 through the plastering glue layer 52. The anchor piece 4 is an expansion ingot for fixing, installed on the outside of the glass fiber mesh cloth 6, and fixed to the wall through the insulation layer 2. Overall, the strength of the entire wall is greatly enhanced, and the durability ...

Abstract

The invention relates to an outer wall heat-preserving system, which comprises a bonding mortar layer, a heat-preserving layer, a surfactant layer, a rendering coat mortar layer, glass fiber gridding cloth, an anchoring piece and a finishing coat, wherein the inner surface of the heat-preserving layer is bonded on a wall body by coating the bonding mortar layer; the surfactant layer is coated on the outer surface of the heat-preserving layer; the inner surface of the glass fiber gridding cloth is bonded on the surfactant layer through the rendering coat mortar layer; the finishing coat is bonded on the outer surface of the glass fiber gridding cloth through the rendering coat mortar layer; and the anchoring piece is arranged on the outer side of the glass fiber gridding cloth, and is fixed on the wall body by passing through the heat-preserving layer. Compared with the prior art, the outer wall heat-preserving system has the advantages of safety, moisture resistance, corrosion resistance, insect pest resistance, molding resistance, high heat-preserving performance, high sound insulating performance, high fire resistance, high durability, and the like.

Description

technical field [0001] The invention relates to a building exterior wall surface, in particular to an exterior wall thermal insulation system. Background technique [0002] At present, the external wall insulation system commonly used in construction projects has certain defects in construction. The wall is easy to crack, the durability is not enough, and the insulation material does not meet the A-level material standard. Otherwise, it is easy to be used during construction and later. Play a fatal hazard of burning, especially after the Shanghai 11.15 incident, the fire protection requirements for wall insulation materials are getting higher and higher. At present, grade A products for thermal insulation that can metabolize inorganic glass wool appear in the market, such as rock wool board, but the thermal insulation performance of rock wool insulation layer is poor, easy to be damp, deformed and peeled off, and the reinforcement technology is backward, which affects the th...
