Problems solved by technology

Existing waterproof membranes still have poor tenacity and tensile properties, poor aging resistance, and short service life.
Some plastomer-modified asphalt coils have better aging resistance and longer effective working life, but are more expensive. Therefore, some concrete pavements and asphalt pavements do not have special waterproof materials. Therefore, the market urgently needs an aging-resistant membrane. Inexpensive and high-quality waterproof membrane products

Description

technical field [0001] The invention relates to a waterproof coiled material and a manufacturing method thereof, in particular to a thermoplastic modified bitumen waterproof coiled material and a manufacturing method thereof. Background technique [0002] Waterproof membrane is a commonly used building material in construction. In the construction of asphalt pavement, underground engineering, and water conservancy projects, waterproof membrane is of great significance to reduce leakage and withstand high water pressure. The waterproof membrane includes a flexible waterproof membrane with asphalt composite tire inside and a membrane with plastic modified asphalt inside. The existing waterproof coiled material also has poor tenacity and tensile properties, poor aging resistance and short service life. Some plastomer-modified asphalt coils have better aging resistance and longer effective working life, but are more expensive. Therefore, some concrete pavements and asphalt pave...
