Abstract

The invention provides a root-puncture-resistant self-healing waterproof coiled material. The root-puncture-resistant self-healing waterproof coiled material is prepared from No.10 asphalt, No.60 asphalt, a composite root retarder, SBS, PVA, a KH-560 coupling agent, a filler, an active agent, a light stabilizer, coconut oil fatty acid, a sodium perfluoro-octanoate water solution and dicumyl peroxide. The preparation method comprises the steps of premixing, high-speed shearing and mixing, the high-speed shearing speed is 8-10 Kr/min, the environment humidity is kept at 60.5 +/- 0.5%; in the mixing process, the jacking pressure is 0.75-0.8 MPa, and the rotating speed is 65-70 rmp/min. The root-puncture-resistant self-healing waterproof coiled material has excellent root puncture resistance and a long service life, after thermal aging, the root puncture resistant is enhanced and the service life is prolonged; the coiled material also has a large excellent tensile force and good wind uplift resistance, the maximal peak tensile force is 1017-1105 N/50 mm, the wind uplift resistance reaches 12.5-14.8 KPa, and the application range is wide.
