Embodiment Construction

[0028] Example figure 1 , 2 shown. The polyurethane external thermal insulation wall is bonded with a layer of polyurethane primer 2 on the base layer 1, and a layer of longitude and latitude grid lines 9 is hung on the polyurethane primer. The diameter of the external longitude and latitude grid lines is less than 1.0mm. It is equal to the thickness of the insulation layer, and the small square with the longitude and latitude grid line outside is a square or rectangle with a side length less than 1m. Then the polyurethane rigid foam insulation layer 3 sprayed on site, the interface layer 4 is outside the insulation layer, the leveling layer is light plastering mortar 5 leveling, and polymer anti-cracking mortar or light plastering mortar 7 is pressed into alkali-resistant glass fiber Mesh cloth6.

[0029] The thickness of the light-weight plastering mortar layer is 5mm-25mm, preferably 5mm-10mm, and the distance between the alkali-resistant glass fiber mesh cloth and the o...

Abstract

The construction process of heat insulating polyurethane wall includes the steps of: base wall treatment; painting polyurethane primer; forming checkers with metal wire or non-metal wire; spraying hard polyurethane, trimming surface; leveling with light facing mortar, plastering anticrack polymer mortar or light facing mortar compounded with organic polymer, inorganic silicate and light aggregate, and pressing alkali-resisting glass fiber netted cloth; and finally scraping flexible putty or spraying relief paint and paint facing laying. The present invention has the advantages of excellent heat insulating performance, short construction period and low cost.

Description

(1) Technical field [0001] The invention relates to a thermal insulation wall body and a construction method. (2) Background technology [0002] Among the current energy-saving technologies for building envelope structures, external thermal insulation technology is widely used due to its advantages of not occupying indoor space. The existing external thermal insulation walls mainly include polystyrene particle slurry, pasted polystyrene board, cast-in-place polystyrene board, rock wool board, foam glass and other walls. The thermal conductivity of some thermal insulation materials is relatively high, which is not suitable for thermal insulation and energy saving in severe cold areas and the needs of higher energy-saving requirements. The problem of anti-cracking is more difficult to solve. At present, there is no external thermal insulation wall and construction method that simultaneously have the characteristics of good thermal insulation performance, easy construction, s...
