High-barrier composite membrane and manufacture method thereof for vacuum heat-insulating plate
Technical field
The present invention relates to a kind of covering material half for the warming plate that vacuumizes, specifically a kind of high-barrier composite membrane and manufacture method thereof.
Background technology
The problems such as existing evacuating vacuum insulation panels high-isolation film is mainly made by aluminium foil, PET film, nylon film or PP film, and its shortcoming is to exist to be afraid of to scratch, and is afraid of to pierce through, not firm with cement mortar bonding, not anti-aging, not alkaline-resisting.Once be pierced in construction, not only greatly reduce heat-proof quality, and the structure of whole heat-insulation layer is damaged.
Summary of the invention
The present invention aims to provide a kind of high-barrier composite membrane for vacuum heat-insulating plate and manufacture method thereof, with solve existing vacuum heat-insulating plate for the bonding of building, aging, the series of problems such as scratch, pierce through.
Technical scheme of the present invention is: a kind of high-barrier composite membrane for vacuum heat-insulating plate, it is characterized in that, and in the inside and outside both sides of high-isolation film, use the compound two layers of glass fabric of method of heat seal, form glass fabric composite membrane.
Described high-isolation film is aluminizer, PET film, nylon film, PVC film, EVOH film, PE film or PP film.
The hot bonding method of described glass fabric composite membrane is: by aluminizer, PET film, nylon film, PVC film, EVOH film, PE film or PP film on film heat sealing machine by adding the form held by its all or part of being melted between two layers of glass fabric, and press together by cooling leveling, become duplex plating lead glass fiber cloth, double-layer PET glass fabric, double-layer nylon glass fabric, double-deck PVC glass fabric, double-deck EVOH glass fabric, double-deck PE glass fabric or double-deck PP glass fabric.
Described glass fabric composite membrane and a kind of obstruct composite membrane are compounded to form high-barrier composite membrane, and combination process is that conventional dry method or wet method are compound.
One or more any combination of described obstruct composite membrane in aluminium foil, aluminizer, PET film, nylon film, PVC film, EVOH film or PP film carried out compound.
Innermost layer at described obstruct composite membrane is provided with PE film, and in this obstruct composite membrane, the combination process of each tunic is conventional composite dry process.
The specification of described glass fabric is 50-500g/m

Advantage of the present invention is: at the compound two layers of glass fabric of outermost of original high-isolation film of vacuum heat-insulating plate, utilize excellent affinity and the adhesion strength of glass fabric and cement, can effectively solve that the fearness that conventional vacuum heat-insulating plate high-isolation film exists scratches, is afraid of to pierce through,, not aging-resistant problem not firm with cement mortar bonding, solve existing vacuum heat-insulating plate for architectural hard nut to crack.
The specific embodiment
The present invention is a kind of high-barrier composite membrane for vacuum heat-insulating plate and manufacture method thereof, and the two layers of glass fabric composite membrane of heat-sealing machine thermal synthesis for both sides at existing vacuum heat-insulating plate covering material half high-isolation film, are called double glazing fiber cloth composite membrane.
Described high-isolation film is aluminizer, PET film, nylon film, PVC film, EVOH film, PE film or PP film.Concrete hot bonding method is: by aluminizer, PET film, nylon film, PVC film, EVOH film, PE film or PP film on film heat sealing machine by adding the form held by its all or part of being melted between two layers of glass fabric, and press together by cooling leveling, become duplex plating lead glass fiber cloth, double-layer PET glass fabric, double-layer nylon glass fabric, double-deck PVC glass fabric, double-deck EVOH glass fabric, double-deck PE glass fabric or double-deck PP glass fabric, be referred to as double glazing fiber cloth composite membrane.
Prepared double glazing fiber cloth composite membrane need intercept composite membrane by conventional dry method or wet method combination process compound (being bonded together as heated the mode of pressurizeing by binding agent on conventional combination machine based on dry operation or on wet method compounding machine) with routine when as evacuating vacuum insulation panels covering material half, intercepts composite membrane in inner side.
The conventional composite membrane that intercepts is that one or more any combination in aluminium foil, aluminizer, PET film, nylon film, PVC film, EVOH film or PP film is carried out compound, and at the innermost layer that intercepts composite membrane, be provided with PE film, the combination process of each tunic is conventional composite dry process (being bonded together as heated the mode of pressurizeing by binding agent on conventional combination machine based on dry operation).
The specification of described glass fabric is 50-500g/m
