Description
Technical field
The utility model belongs to building material technical field, is specifically related to the high-strength film of a kind of insulation water proof.
Background technology
In the prior art, the heat insulation paper tinsel of space metal (AL) being arranged, be called for short " pulling out heat " (PARSEL), is a kind of waterproof insulation construction material that is used for roofing and body of wall.This material has a kind of halogen-containing fire retardant, can emit more halogen during burning and isolate with oxygen, plays the fire-retardant effect of fire extinguishing.But halogen is poisonous, and has dense smoke to produce.And its mechanical strength is big inadequately, can not prevent to be punctured by accident, can not directly lay occasions such as roof separately.
Summary of the invention
The purpose of this utility model is to design a kind of waterproof, high insulating effect, the mechanical strength height, and long service life, technology simply are incubated the high-strength film of water proof.
The high-strength film of insulation water proof of the utility model design is bonded as one wholely and constitute through powerful glue-line by 2 groups of composite membranes, its structure as shown in drawings.Wherein, first group of composite membrane be followed successively by laminated polyester film (PET) 1, with physical vapor deposition at the metallic diaphragm on the laminated polyester film 2: aluminium (Al) layer or zinc (Zn) layer, the metal oxide rete 3 that on metallic diaphragm, forms: alumina layer (Al with electric spark band oxide growth
2O
3) or zinc oxide film (ZnO), powerful glue-line 4 and glass layer 5; Second group of composite membrane be followed successively by high-strength polyester thin layer (BOPET) 6, with the metallic diaphragm 2 of physical vapor deposition on the high-strength polyester thin layer: aluminium (Al) layer or zinc (Zn) layer, the metal oxide rete 3 that on metallic diaphragm, forms: alumina layer or zinc oxide film, powerful glue-line 4, glass layer 5 with electric spark band oxide growth.2 groups of composite membranes are bonded into 11 layers of structure.
In the utility model, laminated polyester film 1 thickness can be 0.012～0.0015mm, metallic diaphragm 2 thickness are 100～150 , metal oxide layer 3 thickness are 40～50 , powerful glue-line 4 thickness are 0.006～0.05mm, glass layer 5 thickness can be 0.2～0.25mm, and high-strength polyester thin layer 6 thickness can be 60～70 ; The gross thickness of the composite membrane of 11 layers of structure is generally 0.50～0.65mm.
In the utility model,, metallic aluminium or zinc are deposited on polyester film and the high-strength polyester film, use the method growing metal oxide skin(coating) of electric spark entrain oxygen gas again, make three's strong bonded owing to adopt the physical vapor deposition method; And this oxide skin(coating) and vacuum to form thicker oxide layer different, it is mainly used in and prevents metal level oxidation in air.
In the utility model, adopt 2 layers of glass layer, make it have good heat-insulating property; Wherein also adopt the high-strength polyester film, the PET that this film is more general has higher mechanical strength: its hot strength is 220MPa～246MPa, and tearing strength is 260MPa～285MPa.Therefore, whole composite membrane mechanical strength is bigger, and its hot strength reaches 330MPa～360MPa, and tearing strength reaches 400MPa～450MPa.
In the utility model, metal oxide layer and glass layer of first and second group film are bonding by powerful glue-line, and be also bonding by powerful glue-line between two groups of films, makes it into as a wholely, more strengthened the combination property of each rete.
The composite membrane of the utility model design has following characteristics:
1, in the composite membrane, PET, BOPET etc. go to zero to the permeability of water.Again because powerful bonding more than 3 times through glue, be zero to the infiltration of rainwater, make film have good water proof effect;
Therefore 2, the double layer of metal film being arranged in the composite membrane, is zero to infrared radiation transmission, and 2 layers of glass fiber are arranged in addition, and thermal conductance is gone to zero, and makes that film is heat insulation, heat insulation effect is splendid; And glass fiber can increase the surperficial friction of film.
3, this composite membrane adopts PET and BOPET, its mechanical strength is much higher than similar products at home and abroad, its hot strength reaches more than the 330Mpa, tearing strength reaches more than the 400Mpa, can stand the mill of rubble in construction consults, have indomitable toughness and very high tearing strength, can be used for roof of buildings and wall, also can be applied to express highway roadbed and railway bed;
4, in general material, if the simple metal layer is directly compound with glue, its life-span can be very not long.In this composite membrane, make metal film oxidation in oxygen with the shortness of breath of electric spark entrain oxygen, under protect oxide layer, the metal film life-span can have more than 20 years.
Description of drawings
Fig. 1 is the structural diagrams of this composite membrane.
Number in the figure: 1 is the polyester rete, and 2 is metallic diaphragm, and 3 is the metal oxide rete, and 4 is powerful glue-line, and 5 is glass layer, and 6 is the high-strength polyester rete.
The specific embodiment
Below by embodiment the specific embodiment of the present utility model is described.
Embodiment, as shown in Figure 1.Metal level 2 is aluminium (Al), adopts the preparation of physical deposition method on the polyester film 1 and on the high-strength polyester thin layer 6, and growing respectively with electric spark band oxygen forms alumina rete 3 again, with seccotine that glass fiber 5 and pellumina 3 is bonding, obtains two groups of films.Then, two groups of films get final product with seccotine is bonding.The gross thickness of composite membrane is 0.60mm.After tested, heat reflectivity is greater than 0.95, and infrared reflectivity is greater than 0.90, and ir transmissivity is 0～0.02%, impact strength (falling ball method) crack-free, and tearing strength (right-angle tearing method) is 450N/mm
