Waterproof film and manufacturing method thereof

The invention discloses a waterproof film comprising a waterproof layer and a protective layer which are adhered through a waterproof adhesive, the waterproof layer is composed of the following components: 50 to 60 parts of polyurethane, 10 to 15 parts of a toughening agent, 8 to 10 parts of polyethylene resin, 20 to 25 parts of nano montmorillonite, 2 to 6 parts of glass fiber, 25 to 30 parts ofa toughening master batch, 2 to 5 parts of a compatilizer, 2 to 6 parts of an epoxy resin, 2 to 6 parts of calcium carbonate, 3 to 7 parts of nano titanium dioxide sol and 1 to 5 parts of halloysite nanotube. The invention further provides a manufacturing method of the waterproof film. According to the waterproof film, on the premise that the waterproof effect is guaranteed, the strength and toughness of the film are improved, the situation that tearing occurs in the pulling and laying process is avoided, and the waterproof effect is stable. 本发明公开了一种防水膜，包括通过防水粘连剂粘黏的防水层和保护层，所述防水层是由以下组分的成份构成，聚氨酯50-60份，增韧剂10-15份，聚乙烯树脂8-1
