Abstract

The utility model provides a heat preservation and decoration composite plate with good heat preservation performance, light weight, stable performance and low cost for an external wall of a building. The utility model comprises a heat preservation layer, an isolation layer and a decorative surface coating layer. Because the heat preservation layer is made of non-flammable polyurethane through foaming, the utility model has the advantages that the heat preservation performance is good, the weight is light, the chemical structure is stable, the utility model is uneasy to be distorted, has the functions of heat preservation and aluminum decorative plate frame enhancement, and ensures the facing to be kept smooth for a long time and to get no distortion; the isolation layer adopts an aluminum plate with the thickness of 0.1 to 0.9 mm, thereby the weight of the heat-preserving plate is light, and the cost of the heat-preserving plate material is low.

Description

The polyurethane exterior wall thermal insulation decoration composite plate

Technical field

The utility model belongs to building material technical field, relates to a kind of skin decorative composite material, is specifically related to a kind of skin heat-insulating decorative composite board.

Background technology

Decoration of exterior wall is important engineering in the building trade, and external wall decorative material also becomes the most basic a kind of constructional materials.Continuous development along with economy and technology has also proposed new requirement to architectural decoration, and various functional building materials continue to bring out, and insulation and decoration exterior wall also layer goes out not group.At present, the kind of outer wall heat insulating and decorating plate material is a lot, but the outer wall heat insulating and decorating plate material is to be composited by insulation layer, enhancement layer and incrustation coating mostly, wherein insulation layer adopts expanded polystyrene (EPS) mostly, heat-insulating property is relatively poor, and self intensity is not higher, need the glass fiber screen cloth, or the guiding principle silk screen gains in strength, then could plaster leveling, operation is many, decorate curtain wall, the dry-hang stones used, owing to fixed form cost height, heat-insulating property is poor more, the high-altitude exists potential danger, and country's restriction is used.The aluminium-plastic panel of usefulness has also limited its scope of application because plate face time long back modification is serious now.

Decoration of exterior wall in the builing industry mainly adopts and with fixture heat insulating thermal preserving board is fixed on the body of wall earlier at present, and then strengthen with glass fiber screen cloth or steel mesh, plaster again and do external protection, the last job practices of doing architectural surface again, and mostly construction is that manual behaviour does, on-site construction processes is various, and the quality control difficulty is big; It is temporarily no problem both to have made after the construction, and the time has been grown and also occurred easily partly coming off, and plays phenomenons such as bag.

Summary of the invention

The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of good heat insulating, lightweight, stable performance, skin heat-insulating decorative composite board with low cost are provided.

Exterior wall heat preserving decorative composite plate of the present utility model comprises insulation layer, separation layer and decorative cover coating, and wherein separation layer is that thickness is the aluminium sheet of 0.1～0.9mm, and insulation layer is the hard polyurethane foam plate of thickness 30～90mm; The decorative cover coating can be in true mineral varnish, metallic paint, the fluorine carbon lacquer any.

Because insulation layer adopts the polyurethane foam of difficult combustion to form, its good heat insulating, light weight, steady chemical structure, flexible type not plays the skeleton booster action of insulation and aluminium decorative board, can make the smooth not modification of the long-term maintenance of facing; Separation layer adopts thin aluminum sheet, makes the light weight of heat preservation plate material, cost low.

The specific embodiment

A kind of exterior wall heat preserving decorative composite plate, comprise insulation layer (1), separation layer (2) and decorative cover coating (3), wherein insulation layer is the hard polyurethane foam plate of thickness 30～90mm, separation layer is that thickness is the aluminium sheet of 0.1～0.9mm, on the tinuous production of hard polyurethane foam warming plate, do separation layer with aluminium sheet, aluminium sheet just and polyurethane plate adhered to securely together that separation layer and insulation layer bond together; The decorative cover coating can adopt true mineral varnish, metallic paint, fluorine carbon lacquer etc. according to different needs, and these decorative cover coatings can adopt some conventional spraying equipment and technologies, covers on the single face that is applied to the aluminium sheet separation layer, and does the finish coat protection with mucous membrane or paper.For the ease of construction, guarantee construction quality, the prefabricated thickness of composite plate lacks 10mm than the thickness that working design requires.

Claims (1)

1. a polyurethane exterior wall thermal insulation decoration composite plate comprises insulation layer, separation layer and decorative cover coating, it is characterized in that: described separation layer is that thickness is the aluminium sheet of 0.1～0.9mm, and described insulation layer is the hard polyurethane foam plate of thickness 30～90mm.
