Metal composite film for waterproof coiled material and preparation method of metal composite film
The metal composite film comprises a transparent weather-proof layer, an aluminum foil layer and a PET layer which are sequentially arranged from top to bottom and bonded and compounded into a whole through a glue layer, the transparent weather-proof layer is a polyvinylidene fluoride modified layer, and the glue layer is bi-component polyurethane glue. According to the scheme, the coating compound machine is used for coating and compounding the transparent weather-proof layer, the aluminum foil layer and the PET layer, and the prepared metal composite film is good in weather resistance and corrosion resistance; polyvinylidene fluoride is adopted as a main material and methacrylic resin is adopted as an auxiliary material to prepare the transparent weather-resistant layer, so that the transparent weather-resistant layer has excellent tensile property, and after the composite film is subjected to tensile deformation in a certain shape, the weather-resistant and corrosion-resistant properties of the composite film are not influenced at all.
本发明公开了一种防水卷材用金属复合膜，包括自上而下依次排列并通过胶水层粘接复合为一体的透明耐候层、铝箔层以及PET层，所述透明耐候层为聚偏氟乙烯改性层，所述胶水层为双组分聚氨酯胶水。本发明方案以涂布复合机涂布复合透明耐候层、铝箔层以及PET层，制备的金属复合膜耐候耐腐蚀性能性能好；采用聚偏氟乙烯为主料、甲基丙烯酸树脂为辅料制备透明耐候层，使其具有优异的拉伸性能，在复合膜经过一定形状的拉伸变形后，丝毫不影响其耐候耐腐蚀性能。
