Abstract

The utility model relates to a piece of thermal insulation material for buildings, which particularly relates to a multi-efficient composite thermal insulation board for the thermal insulation of external walls and roof coverings of buildings. The multi-efficient composite thermal insulation board is composed of a thermal insulation layer, an air space layer, a reflecting layer and an armor layer, wherein, the air space layer is made of perforated plates, the reflecting layer is glued on the air space layer, the air space layer and the thermal insulation layer are combined and form a heat-insulating layer, and the armour layer is compounded outside of the heat-insulating layer. The utility model has the advantages of good thermal insulation property, light weight, low cost and thin thickness with identical heat resistance values, and can be widely used for the thermal insulation of building walls and roof coverings.

Description

Multiple-effect can composite insulation boards

The utility model belongs to building thermal insulation material, and particularly relating to a kind of multiple-effect that is used for building masonry wall, roof heat insulation can composite insulation boards.

In the builing industry, roofing heat insulating material mainly adopts porous materials such as gas concrete, cement expanded perlite at present; And body of wall is not generally taked the insulation measure.Along with the development of society, the heat-insulating property of building has been proposed more and more higher requirement, and heat insulating material for building commonly used is now only considered from the conduction aspect of heat, and seldom had consideration thermal-radiating.

The purpose of this utility model provides a kind ofly can effectively prevent conduction of heat and heat radiation, multiple-effect in light weight, that cost is low can composite insulation boards.

The technical solution of the utility model is as follows:

A kind of multiple-effect energy composite insulation boards comprises armour layer, isolation layer, reflecting layer, it is characterized in that isolation layer is combined by insulation layer and airspace layer, and the airspace layer is an orifice plate that has many holes; Isolation layer also can be simultaneously to have a plurality of blind holes at insulation layer, posts a reflecting layer on the layer of airspace; In the isolation layer surface recombination armour layer is arranged, armour layer can be that tough layer of light weight concrete construction or cement glass fiber or sheet metal are formed.

Characteristics of the present utility model are 1. to be incubated, thermal insulation is good; Compare with general heat insulating material, its thermal resistance value can double; 2. can effectively reduce the thickness of heat insulating material, so under the situation of same building area, increase effective usable floor area; 3. in light weight, cost is low, so just can reduce the cost of construction work.

Embodiment of the present utility model is explanation in detail in conjunction with the accompanying drawings.

Accompanying drawing 1 is the structural representation of the utility model embodiment one.

Accompanying drawing 2 is the structural representation of the utility model embodiment two.

Embodiment one:

As shown in Figure 1, multiple-effect can be made up of armour layer 1, two-layer isolation layer 3 and individual layer reflecting layer 2 by composite insulation boards, isolation layer 3 by insulation layer 3 ' and airspace layer 4 combine, insulation layer 3 ' can make by styrofoam or other light heat insulation material such as rock wool, glass wool, airspace layer 4 is by the orifice plate that has many holes on the styrofoam plate, hole 5 on the orifice plate can be the hole of rule, also can be that irregular hole 5 is formed; Post a reflecting layer 2 in the one side of airspace layer 4, reflecting layer 2 can be that the good materials of reflectivity such as aluminium foil or aluminized plastic film are made; When heat by behind the insulation layer 3 ' enter airspace layer 4, heat will change radiation into or the air transmitted mode is passed through airspace layer 4, at this moment its heat reflection usefulness can be given full play in reflecting layer 2, some heat is after passing through reflecting layer 2, also will through airspace layer 4 and insulation layer 3 ', so, heat insulation effect is just very good.Surface recombination at isolation layer 3 has armour layer 1, and armour layer 1 can be according to the needs of building aspect, is made by light weight concrete construction or cement glass fiber obdurability armour layer or sheet metal.It can be widely used in the insulation of roofing and body of wall.

Embodiment 2:

As shown in Figure 1, multiple-effect can composite insulation boards by armour layer 1, individual layer airspace layer 4, reflecting layer 2 and two-layer insulation layer 3 ' forms, individual layer airspace layer 4 can be insulation layer 3 ' on blind hole 5 formation of opening; When heat by first floor insulation layer 3 ' after, enter airspace layer 4, because the air effect heat in the hole 5 can only pass through airspace layer 4 by radiation or air transmitted mode, reflecting layer 2 can give full play to its effect enter then insulation layer 3 ', heat need carry out through conduction and radiation dual mode like this, and this just can improve heat insulation effect greatly.Insulation layer 3 ' can be made by styrofoam or other light heat insulation material such as rock wool, glass wool, reflecting layer 2 can be that aluminium foil or aluminized plastic film or the good material of other reflectivity are made, and reflecting layer 2 directly is attached on the airspace layer 4.Surface recombination at isolation layer 3 has armour layer 1, and armour layer 1 can be made by light weight concrete construction or cement glass fiber obdurability armour layer or sheet metal according to the needs of construction, and it can be widely used in the insulation of roofing and the insulation aspect of body of wall.
