3. described foil laminated film is cut by needed size, the foil laminated film after will cutting is then made uniform fold through machining and is formed aluminium foil fold composite membrane under 100～120 ℃ temperature;
4. select or the making butyl rubber belt, described butyl rubber belt applies butyl rubber and processes on substrate;
5. described aluminium foil fold composite membrane and described butyl rubber belt are formed the composite aluminium film elasticity flashing with flaabellum shape aluminium foil fold through fashion of extrusion.
The thickness of described PET polyester film is 0.015mm～0.016mm.
The length of side of the single fold of described aluminium foil fold composite membrane is 3mm～6mm.
The thickness of the butyl rubber of described butyl rubber belt is more than or equal to 1.2mm.
When composite aluminium film elasticity flashing of the present invention uses, after described substrate removed, the one side of described butyl rubber directly sticked on roof structure seam waterproof details position get final product.
Compared with prior art, beneficial effect of the present invention is following:
1, owing to aluminium foil fold composite membrane of the present invention is also formed through the system fold by aluminium foil two sides difference polyurethane and PET polyester film; Polyurethane is water-proof and anti-corrosive material; Have intensity height, water-tolerant; Anticorrosion, make the aluminium foil upper surface form the firm water-tight corrosion-proof rete of one deck again, described PET (PETG) polyester film is a high polymer; Has better heat-resisting; Chemical proofing, obdurability, electrical insulating property and safety make composite aluminium film elasticity flashing of the present invention have preferably waterproof, anticorrosion, heat-resisting, chemical proofing, obdurability, electrical insulating property and safety, also have the good anti-root performance to plant growing.
2, because the present invention adopts the aluminium foil fold composite membrane of flaabellum shape accordion and the composite construction of butyl rubber, and described butyl rubber has pressure-sensitive haptoreaction property, firm with the roofing bonding, the molecule infiltration property of butyl rubber makes its permanent adhesive property better.
3, the integral extension property of aluminium foil fold composite membrane of the present invention is promoted to 40%, so the present invention has remarkable stretching ductility, has the good heat resistanceheat resistant shrinkage performance that expands.
4, the superior ageing resistance of the present invention, lasting caking property, can-10 the degree to 80 the degree large-scale temperature under smooth construction, be a kind of better elastic flashing material.
