Embodiment 1

[0036] Embodiment 1, thermal insulation concrete wall

[0037] according to figure 1 The process flow shown is used to prepare the thermal insulation wall (for a certain house in a certain community). First, the concrete layer 1 of the base wall is processed, and the reference line is hung. Hang a vertical reference line at each floor, and hang a horizontal line at an appropriate position on each floor to control the verticality and levelness of the foamed cement board. Then, interface mortar and waterproof mortar are painted sequentially on the treated concrete layer 1 to obtain an interface layer 2 and a leveling layer 3 respectively. Then paint the bonding mortar on the leveling layer 3 to obtain the bonding layer 4 . Continue to paste the foam insulation board on the adhesive layer 4 as the insulation layer 5. When the foam insulation board is pasted on the adhesive layer 4, the full paste method should be used, and the following requirements should be met:

Embodiment 2

[0081] Embodiment 2, thermal insulation masonry wall

[0082] Prepare the thermal insulation wall (for a certain house in a certain community) according to the method and steps basically the same as in Example 1. First, process the base wall masonry, hang the reference line, and place it on each corner of the outer wall (yang corner, Inner corners) and other necessary places to hang vertical reference lines, and hang horizontal lines at appropriate positions on each floor to control the verticality and levelness of the foamed cement board. Then apply waterproof mortar on the treated masonry to obtain a leveling layer. Then paint the bonding mortar on the leveling layer to obtain the bonding layer. Continue to paste the foam insulation board on the adhesive layer as the insulation layer. When the foam insulation board is pasted on the adhesive layer, the full paste method should be used, and the following requirements should be met:

[0083] (1) The floating dust on the surfa...

Abstract

The invention discloses a heat-insulating wall. The heat-insulating wall comprises a base course wall body, a bonding layer, an insulating layer, a plastering layer and a decorating layer which are stacked together sequentially, wherein the insulating layer is formed by foaming cement insulating plates, and the thickness of the insulating layer is not less than 25 mm; and the base course wall body is a masonry wall body or a concrete wall body. The heat-insulating wall provided by the invention has the advantages as follows: good fire-resistant and heat-insulating performance: the foaming cement plates are made of A-grade incombustible inorganic heat-insulating materials, and the refractory limit is over 3 hours, so that the fire-resistant performance of a building can be improved when the foaming cement plates are used on the building, and as the percentage of close area of the foaming cement plates is greater than 95 percent, good heat-insulating performance is achieved, and the building energy conservation reaches more than 65 percent; light weight and strong vibration-resistant performance: the product is light in unit weight and vibration-resistant, and has the desiccated bulk density of 120-200 kg/cubic metre, and the heat conductivity coefficient of less than 0.045 W/(m.K); and good sound-insulating performance: as the foaming cement plates are formed by innumerous independent porous bubbles, the sound absorption effect is about 5 times higher of the common concrete, and the sound-insulating coefficient is greater than 45 dB.

Description

technical field [0001] The invention relates to a thermal insulation wall body. Background technique [0002] The Chinese government has made the development of a low-carbon economy and the construction of a low-carbon society a basic national policy and development strategy. The core of reducing carbon emissions is building energy conservation, because building energy consumption accounts for 22% of the country's total energy consumption, and the carbon dioxide emitted by burning coal for heating and air-conditioning electricity consumption accounts for about 25% of my country's carbon emissions. The core of building energy saving is building thermal insulation. Over the years, my country's building insulation has been dominated by foam. After more than 10 years of application, fire accidents caused by foam plastic insulation have occurred frequently, engineering accidents of large-scale peeling off of the insulation layer have occurred continuously, and the aging problem...
