Abstract
The utility model discloses an aluminum foil composite heat insulating sandwich board, which is formed in the method that the upper and the lower surfaces of a hard thermal insulating board material with the thickness of 1-10CM are respectively covered with a layer of aluminum foil with the thickness between 30 and 150 mum. The utility model is a thermal insulating material which has the advantages of certain strength, light weight, good heat insulating and thermal insulating effect, and low water absorption rate. An air conditioner ventilating pipe manufactured by the board material has the characteristics of long service life, no cold bridge phenomenon, low noise, etc. The utility model is an ideal preparation material for the air conditioner ventilating pipe.
Description
Technical field
The utility model relates to a kind of heat-insulation material, particularly a kind of aluminium foil compound heat-insulation sandwich board.
Background technique
The thermal insulating material form and the kind of domestic production at present are more, use wide generally, have played energy-saving effect preferably.But its structural type great majority are sheet material or the section bars that constitute with a mono-material, and its intensity and moisture proofness are all relatively poor, can not directly be used in some special occasions.The present domestic adiabatic method that is used for the central air-conditioner ventilation duct for example, a large amount of use still with the galvanized sheet iron airduct make inner bag, in addition traditional thermal insulating material constitutes the form of thermal-protective coating outward.The airduct adiabatic method of this form exists that lap-joint's imprecision, cold bridge phenomenon are serious, working life is short and defective such as own wt is heavier, does not meet the requirement of modern architecture to the air-conditioning duct system.
Summary of the invention
The utility model is for solving the defective of above-mentioned ventilation duct of air conditioner constituent material, a kind of novel heat-insulation and heat-preservation sheet material is provided, and its light weight, heat insulation and preservation effect are good, and are easy to construction and installation, are particularly suitable for the making of central air-conditioner ventilation duct.
The utility model is that the technological scheme that addresses the above problem proposition is: upper and lower two surfaces at the hard heat-insulated sheet material of thickness 1-10cm respectively are covered with the aluminium foil of a layer thickness at 30-150 μ m, constitute that a kind of existing certain intensity, weight are light again, good heat-insulation effect, aluminium foil compound heat-insulation sandwich board that water absorption rate is low.Characteristics such as that the ventilation duct of air conditioner that adopts this sheet material directly to make has is in light weight, high insulating effect, no cold bridge phenomenon, long service life meet the supporting requirement of modern building.
Description of drawings
Fig. 1 is perspective view of the present utility model.
Embodiment
In conjunction with Fig. 1, at thickness is upper and lower two surfaces of the hard polyurethane foam sheet material 2 between the 1-10cm, respectively covering the aluminium foil 1 and 3 of a layer thickness between 30-150 μ m, is that aluminium foil, centre are the compound heat-insulation sandwich board of hard insulating material thereby constituted a kind of surface.
Claims (2)
1, a kind of aluminium foil compound heat-insulation sandwich board is characterized in that at thickness being that upper and lower two surfaces of the hard heat-insulated sheet material (2) of 1-10cm respectively are covered with aluminium foil (1) and (3) of a layer thickness at 30-150 μ m.
2, a kind of aluminium foil compound heat-insulation sandwich board according to claim 1 is characterized in that said hard heat-insulated sheet material (2) is a kind of sheet material that is made of blown polyurethane materials.
