PET Complex waterproof sheet using polyethylene terephtalate sheet manufacturing method of the complex waterproof sheet and construction method using the complex waterproof sheet

摘要

The present invention relates to a complex waterproof sheet using a PET sheet, a manufacturing method thereof, and a construction method using the same, wherein neighboring PET sheets can be easily attached to each other. According to the present invention, the complex waterproof sheet comprises: a PET sheet; a solventless type adhesive applied and attached to one surface of the PET sheet to provide the PET sheet with self-adhesion properties; and release paper attached to one surface of the PET sheet to which the adhesive is applied and attached. The solventless type adhesive enables thermoplastic resin-shaped elastic rubber, rubber adhesive grey fabrics, and tackifiers to be mixed with and dissolved in solvent agent oil heated in a heated liquid stirring machine. Moreover, the adhesive is mixed with at least one of thermostabilizers, antioxidants, reinforcing agents, and fillers.
