Abstract

The invention provides a double-sided adhesive asphalt-base and PET (polyethylene terephthalate)-carrier wet-laid waterproof roll. The waterproof roll comprises a PET film, a modified asphalt layer and PE (polyethylene) film, wherein the PET film is 0.1-0.2 mm thick, the modified asphalt layer is 0.7-1.5 mm thick, and the PE film is 0.03-0.05 mm thick; raw material components of the modified asphalt layer comprise, in parts by mass, 245-260 parts of petroleum asphalt, 25-32 parts of second vacuum side-stream oil, 8-10 parts of SBS, 16-20 parts of SIS, 15-20 parts of SBR, 10-12 parts of petroleum resin, 2-4 parts of coumarone resin, 1-3 parts of an anti-stripping agent, 0.8-1.2 parts of an antioxidant, 50-60 parts of cement and 40-50 parts of talcum powder. The waterproof roll has good tensile property, high tearing strength and peeling strength, heat resistance and aging resistance.

Description

technical field [0001] The invention relates to a wet-laid waterproof coiled material, in particular to a double-sided adhesive asphalt-based PET carrier wet-laid waterproof coiled material and a production process thereof, belonging to the field of building waterproof materials. Background technique [0002] Wet-laid self-adhesive waterproofing membrane is a high-performance waterproofing membrane. It is based on synthetic rubber, high-quality heavy-duty asphalt, etc., high-quality polyethylene film, fine sand aluminum foil as the upper surface material or no film (double-sided self-adhesive), using peelable silicon-coated film or silicon-coated crepe paper as the surface material. A self-adhesive waterproof membrane made of anti-adhesive isolation material. [0003] The wet-laid self-adhesive waterproof membrane has low requirements on the base surface, and can be constructed on a wet base surface; it shortens the construction period and saves costs; it can achieve full a...
