Embodiment Construction

[0035] A rigid flame-retardant polyurethane foam material 2 is filled between the inorganic fireproof bottom layer 1 and the decorative surface layer 3 to form an integral polyurethane insulation board.

[0036] The inorganic fireproof bottom layer 1 includes cement board or fireproof glass magnesium board.

[0037] The decorative surface layer 3 includes marble, granite, stainless steel, aluminum-plastic composite board, ceramic board, clay board or plastic-steel composite board.

[0038] Described flame-retardant rigid polyurethane foam material 2 comprises A material and B material, and A material and B material are mixed together during use; Wherein A material comprises polyether or polyester polyol; B material comprises crude MDI (polyphenyl polymethylene polyisocyanate).

[0039] The production method of described polyurethane external wall insulation material is as follows:

[0040](1) Raw materials: It is a combination of material A and material B, and material A is ...

Abstract

The invention relates to an external heat insulation board structure for a polyurethane external wall, which is mainly used for the modern building external wall external heat insulation technical field. The structure mainly comprises an inorganic fireproofing bottom layer, a flame-retardant hard polyurethane foam material, a decorative surface layer and so on. The structure has convenient and simple installation: firstly, the surface of a base course wall body is treated to remove floating ash on the surface of the base course wall body, then bonding mortar is used to level the surface of the base course wall body and then is used to directly and dryly paste one surface of the inorganic fireproofing bottom layer of a polyurethane heat insulation board on the surface of the external wall (whether an expanding screw is used to fix is determined according to the concrete requirement); a heat insulation wall body of the external wall can directly use materials such as marbles and so on as a finish layer, so only the waterproofing treatment at the seams needs to be well done, and the work for producing the finish layer on the surface of the wall body is saved. The quick and convenient installation mode improves the work efficiency of the construction and shortens construction period. At the same time, the energy-saving wall body also has the advantages of good heat insulation effect, excellent water resistance, long service life and so on.

Description

technical field [0001] The invention relates to a novel polyurethane hard foam external wall thermal insulation and its production and installation method. The product is mainly used in the technical field of external thermal insulation of modern buildings (newly built, expanded or reconstructed various buildings). Background technique [0002] Energy conservation has become an important national policy for the development of our society. Building energy conservation plays an important role in energy conservation system engineering. Our government attaches great importance to building energy conservation. Insulating the walls of buildings is one of the effective ways to save energy in buildings. Before the present invention was made, in the prior art, external wall insulation materials such as polystyrene board external wall insulation, thermal insulation mortar, polyurethane rigid foam spraying, etc. were mainly used for external wall insulation. The above-mentioned extern...
