Description

A kind of composite decorating board

The present invention relates to a kind of composite decorating board, particularly metal sheet (or film) and the compound decorative panel of nonmetallic anti-H 2 O calcium sulphate (gypsum) of architectural decoration.

This invention can make full use of anti-H 2 O calcium sulphate (gypsum) and has that the A level does not fire that fireproof performance, rigidity are big, sound insulation, advantage such as heat insulation, not yielding, make full use of metal sheet good toughness, waterproof, protection against the tide again, bear dirty, advantage such as durable, form a kind of NEW TYPE OF COMPOSITE decorative panel that makes both obtain perfect adaptation.

1, the technology status of existing gypsum smallpox decorative panel:

Gypsum smallpox decorative panel of the prior art is to be composited by land plaster (Main Ingredients and Appearance is a calcium sulfate), fiber, waterproof agent and cementitious material etc., the waterproof on ceiling surface, protection against the tide, antifouling treatment technology mainly are that one deck emulsion paint is sprayed on the surface that leans against gypsum plank, but because gypsum is originally as granular structure, emulsion paint itself is not complete waterproof, the easy moisture absorption under wet environment, therefore, existing this kind product exists following deadly defect and defective:

1) gypseous decorating board of granular structure easily split, frangible, often become piece to come off in limit, the bight of plate especially, when carrying out perforate, sawing, very easily rupture, cause very lossy, the gypsum decorative ceiling can only be installed in supporting all around with the bright keel of broad simultaneously, and decorative effect is attractive in appearance inadequately, decoration grade is difficult to improve;

2) gypseous decorating board antidetonation, crashworthiness are poor, and breaking load is very little, and therefore, gypseous decorating board only can be used for smallpox at present to be decorated, and can not be used for the decoration in metope or other places, when earthquake takes place, causes very big threat to indoor occupant and equipment;

3) the latex enamelled coating on existing product surface is in construction and installation and later use, is easy to be mounted personnel or maintenance personal and makes dirty and can't repair, and causes very big spillage of material;

4) existing product is under the infiltration of air-conditioning and water supply and sewerage pipeline or the situation of leaking, and very fast meeting is oozed to wear or leak by water and worn, and causes perforation of plate face or the flavescence of whole plate face and damages.

2, the technology status of existing metal ceiling decorative panel:

Metal ceiling decorative panel of the prior art is to be stamped to form by metal sheet roof covering, but because the characteristic of metal itself and ceiling are too thin (owing to the metal cost height of aluminium particularly, general ceiling is all done very thinly, have only 0.4～0.7mm thick), cause existing this kind product to have following weakness and defective:

1) because metal ceiling itself can not sound insulation, and coefficient of thermal conductivity is very big, and will do sound insulation, heat insulation processing overleaf, and cost is too high again, and the existing metal ceiling back side does not all have sound insulation, heat-barrier material, causes very big waste for the heating installation, cold air etc. of interior of building;

2) because there are some gaps in the performance and the import metal ceiling of existing homemade metal ceiling, cause homemade metal ceiling can't enter high-grade decorative engineering, (as the Le Silong metal ceiling of Holland, the first road of the U.S. reaches the mineral wool smallpox) much all captured by import metal ceiling or mineral wool smallpox in the smallpox decorative engineering market of domestic top grade.

Purpose of the present invention be intended to overcome the deficiencies in the prior art and defective and provide that a kind of rigidity that had both made full use of gypsum plank is big, sound insulation, advantage such as heat insulation, not yielding, the composite decorating board of advantages such as making full use of metal ceiling good toughness, waterproof, protection against the tide again, bear dirty, be durable.This invention can be used for the smallpox decoration can be used for the indoor wall decoration again, can shock resistance have splendid sound insulation, heat-proof quality again, the flat board of small size, regular shape can be made and the large-scale decorative panel of large scale, the variation of various curved surface can be made again, not only being suitable for house decoration but also being suitable for the decoration in places such as senior office premises, hotel, conference centre, exhibition hall, sports palace, airport, cinema, is a kind of environmental protection, energy-conservation environment-friendly decorative material.

The object of the present invention is achieved like this:

A kind of composite decorating board comprises metal sheet (film) surface layer (1), and thickness is 0.01～3mm (when thickness during less than 0.1mm, being called film), cloth intermediate layer (2), and composite bottom layers (3) such as high strength calcium sulfate (gypsum), fiber.

---the thickness of described metal sheet (film) surface layer (1) is 0.01～3mm, and metal sheet (film) surface layer can be even surface, embossing pattern face, perforation sound absorption face or various curved surface, and the shape of metal sheet can be square, rectangle, circle or arc.

---described cloth intermediate layer (2) cements the back side of itself and metal sheet (1) by seccotine, and the long fibre that cloth is stretched out is an integral body with metal sheet surface layer and gypsum bottom strong bonded.

---described composite bottom layer (3) is by being poured into compound material such as gypsum, fiber and cementitious material in the metal sheet back side and forming through vibration compacting, and thickness is 5～50mm.

The invention will be further described below by drawings and Examples:

Fig. 1 is a structural profile schematic diagram of the present invention, and the front is an even surface

Fig. 2 is a structural profile schematic diagram of the present invention, and the front is the embossing pattern face

Fig. 3 is a structural profile schematic diagram of the present invention, and positive is perforation sound absorption face

Among the figure, 1 is metal decking, and 2 is the fiber intermediate layer, and 3 is calcium sulfate (gypsum) composite bottom layer

Now the composite decorating board production with 600 * 600mm is embodiment:

1, metal sheet roof covering is processed into the metal decking (metal sheet upwards turn down the 30mm height all around, so that the cast of bottom gypsum material) of various required patterns or shape in proper order through cutting, punching press etc., also can arrives metal ceiling manufacturer metal decking customized.

2, adhesive glue (available all-purpose adhesive etc.) is coated at the back side of the metal sheet that will handle well, the cloth of 600 * 600mm of having cut is sticked at the back side (have long stapled one to face up, treat and the gypsum bottom links) of metal sheet.
