Inorganic polyurethane heat insulation veneering decoration system

Abstract

The invention relates to an inorganic polyurethane heat insulation veneering decoration system. The system comprises a bottom bonding layer, a heat insulation fireproof plate, a surface bonding layer, a protection facing layer and the like in sequence from an exterior wall base face to the outside. The building heat insulation system has the excellent heat insulation, fireproofing and waterproofing functions. The polyurethane rigid foam (PUR / PIR) plate is used for completely wrapping an external envelope structure of a building. An inorganic flexible facing material with marble paint, solid-color paint, rock slice paint, really stone paint and the like is bonded to the plate surface and has the protection and decoration effects, a plastering layer and a decoration layer are effectively and organically combined into a whole, the problems of surface thickness unevenness, after-contraction and facing cracks caused by field wet work are avoided, the overall quality of the system is guaranteed, wind or moisture is prevented from flowing into or out of the building through gaps, and complete sealing is achieved. Construction is easy and convenient, and the construction period is shortened. The system has wide application fields and can be widely applied to different structure portions such as common exterior walls, arc-shaped exterior walls, corner exterior walls, basement ceilings, accessible flat roofs, pitched roofs and staircases.

Description

technical field [0001] The invention relates to an external wall thermal insulation building material, in particular to an inorganic polyurethane thermal insulation veneer decoration system. Background technique [0002] In the wall insulation system used for building energy conservation in my country for a long time, the external wall insulation technology and the external wall decoration technology are integrated, lacking scientific connection, especially in the compatibility of materials, affinity between layers, There are still many problems in the complementarity of performance and the coordination of construction. The surface layer plastering layer of the thermal insulation system and the exterior wall decoration layer are completed in multiple wet operations, and the quality of construction thickness and construction flatness is difficult to control. There are many processes, the construction is slow, and the construction period is long. As a result, the construction p...

Problems solved by technology

[0002] In the wall insulation system adopted for building energy saving in my country for a long time, the external insulation technology of the building exterior wall and the decoration technology of the exterior wall are integrated, lacking scientific connection, especially in the compatibility of materials, the affinity between layers, There are still many problems in terms of performance complementarity and construction coordination. The surface plastering layer of the thermal insulation system and the exterior wall decoration layer are constructed in multiple wet operations. It is difficult to control the quality of construction thickness and construction flatness. Many processes, slow construction, long construction period

As a result, the construction period is delayed, and the insulation layer is cracked, hollowed out, and even falls off.
