一种防水卷材用PVDF复合TPO耐晒抗老化复合膜及制备方法
摘要：
本发明公开了一种防水卷材用PVDF复合TPO耐晒抗老化复合膜及制备方法，复合膜由依次设置的PVDF膜、胶水层、TPO层、粘合胶层和离型层构成，其中：所述PVDF膜的厚度为0.015～0.025mm，宽度为860mm～1920mm；所述胶水层的厚度为0.0003～0.0005mm，宽度为860mm～1920mm；所述TPO层的厚度为2～5mm，宽度为900mm～1100mm；所述粘合胶层的厚度为1～2mm，宽度为1060mm～2120mm；所述离型层的厚度为0.03～0.04mm，宽度为1060mm～2120mm。能直接用于单层屋面方面和金属屋面外露抗紫外耐晒，克服热塑性聚烯烃弹性体(TPO)片材外露抗晒寿命只有5～10年左右，使用寿命延长到25年，满足新的“市政和建筑防水通用规范”要求，维护成本大大降低。
摘要（英）：

The invention discloses a PVDF and TPO composite sun-proof and anti-aging composite film for a waterproof roll and a preparation method. The PVDF and TPO composite sun-proof and anti-aging composite film for the waterproof roll comprises a PVDF film, a glue water layer, a TPO layer, an adhesive glue layer and a release layer which are arranged in sequence, wherein the thickness of the PVDF film is0.015-0.025 mm, and the width of the PVDF film is 860-1920 mm; the thickness of the glue water layer is 0.0003-0.0005 mm, and the thickness of the glue water layer is 860-1920 mm; the thickness of the TPO layer is 2-5 mm, and the width of the TPO layer is 900-1100 mm; the thickness of the adhesive glue layer is 1-2 mm, and the width of the adhesive glue layer is 1060-2120 mm; and the thickness ofthe release layer is 0.03-0.04 mm, and the width of the release layer is 1060-2120 mm. The PVDF and TPO composite sun-proof and anti-aging composite film for the waterproof roll can be directly usedfor exposed ultraviolet ray resistance and sun resistance of the single-ply roof aspect and the metal roof aspect; a defect that the exposed sun-proof service life of a thermoplastiadc polyolefin elastomer (TPO) sheet is only 5-10 layers is overcome; the service life is prolonged to 25 years; requirements of new municipal and building waterproofing general specification are met; and the maintenance cost is greatly reduced.
