High-stability waterproof roll and production method thereof

The invention relates to the technical field of waterproof coiled materials, in particular to a high-stability waterproof coiled material and a production method thereof. Specifically, the high-stability waterproof coiled material is prepared from the following components in parts by weight: 1 to 5 parts of high-density polyethylene, 60 to 80 parts of composite linear low-density polyethylene, 20 to 40 parts of polypropylene, 10 to 30 parts of master batch and 15 to 20 parts of compatilizer, the composite linear low density polyethylene comprises 75-85% of linear low density polyethylene, 8-15% of ammonium polyphosphate, 1-3% of polypropylene, 1-3% of benzophenone and 2-8% of polyethylene glycol. According to the waterproof roll provided by the invention, the composite linear low-density polyethylene is prepared from the linear low-density polyethylene, the ammonium polyphosphate, the polypropylene, the polybenzophenone, the polyethylene glycol and other components, and the composite linear low-density polyet
