Embodiment Construction

[0023] Such as figure 1 As shown, the external wall thermal insulation and energy-saving system of the present invention includes an internal painting layer 1, a wall surface treatment mortar layer 3, a bonding layer 4, an insulating layer 6, a plastering mortar layer 7 and a decorative surface arranged sequentially from the inside to the outside. Layer 8. in:

[0024] 1. Adhesive layer

[0025] The bonding layer between the thermal insulation layer material and the base wall is also the bonding layer between the external thermal insulation system and the exterior wall 2 of the building. The bonding material adopts a polymer modified adhesive, which is coated on the expanded polystyrene board in the form of dots (middle) frame (periphery) or strips, the coating area is not less than 40% of the area of ​​the polystyrene board, and the coating thickness About 8mm-10mm, the thickness of the bonding layer after pasting is generally 3mm, so the actual pasting area is not less th...

Abstract

The invention discloses an external-wall external-insulation energy-saving system which comprises an internal plastering layer, a wall-surface treating mortar layer, a bonding layer, an insulation layer, a plastering adhesive cement protective layer and a finishing layer that are arranged in sequence from inside to outside, wherein the bonding layer adopts polymer modification bonding agent which contains the following components based on the weight percent: 45-48 of inorganic plural gel material, 45-48 of quartz sand, 5-8 of pure acrylic resin emulsion and 1-2 of auxiliary agents. The invention is suitable for basic-level wall surfaces of various climatic environments and buildings and has the advantages of energy saving, water resistance, moisture resistance, fire prevention, crack resistance and strong protectiveness and durability.

Description

technical field [0001] The invention relates to a heat preservation and energy saving system, in particular to an exterior wall heat preservation and energy saving system which can be used in the building field. Background technique [0002] At present, in the outer protective structure of real estate buildings, the outer wall occupies the largest area. Therefore, reducing the energy consumption of buildings through thermal insulation of external walls is the main measure for building energy conservation. Especially in most buildings at present, the shape coefficient often exceeds the prescriptive index of the building energy-saving design standards, and the heat transfer coefficient of the external windows often cannot meet the requirements. It is necessary to strengthen the external insulation of the external walls to make the energy-saving of the buildings meet the requirements. [0003] External wall insulation is an advanced exterior wall energy-saving technology recog...
