The base of SBS modified asphalt waterproof coiled material mainly includes polyester and glass fiber. The base determines the strength and elongation of SBS modified asphalt waterproofing membrane. Long fiber polyester tire is currently recognized as the tire base material in the world. Modified asphalt coiled material based on polyester tire has the advantages of high tensile strength, high tear strength, good puncture resistance, high elongation, reliable construction technology and long waterproof guarantee period.

Long fiber polyester tire is the main development direction of modified asphalt waterproof coiled material in the future. When the content of SBS is less than 5%, the modification effect is not obvious; When the content of SBS is higher than 15%, the phase separation between SBS and asphalt will occur, and the fluidity of asphalt system will be reduced, which is not conducive to the processing and production of waterproof coiled materials.

Only when the content of SBS is between 5% and 15%, can SBS form a three-dimensional space network structure to surround the asphalt, thus playing a significant role in modifying the asphalt, which not only reduces the brittleness of the asphalt, but also improves the elastoplasticity, elongation, aging resistance, high and low temperature resistance of the asphalt, and maintains the high elasticity of SBS.

The process of coiled material processing equipment must be strictly controlled and equipped with processing and production equipment with high degree of mechanization and automation to ensure stable and reliable quality of coiled material products. The process of SBS modified asphalt is the process of SBS absorbing the light components in the base asphalt, swelling, expanding, and dispersing finer and more evenly in the asphalt.

Therefore, the processing temperature and processing time of SBS modified asphalt will have an impact on the product performance. Considering the various properties of SBS modified asphalt and the production efficiency of waterproof roll, when the processing temperature is controlled at 180~200 ℃, the reasonable processing time of SBS modified asphalt is 1.5~2h.

In a word, the performance of SBS modified asphalt waterproof coiled material is not only related to the raw materials and proportion used, but also closely related to each link of production and processing. Only by controlling the influencing factors of each link can we produce waterproof coiled material with excellent performance.

SBS modified asphalt waterproof coiled material, with the implementation standard of GB18242-2008, is a waterproof material with excellent performance, which is made of styrene butadiene styrene (SBS) rubber modified asphalt as the coating, glass fiber felt, polyester felt, glass fiber reinforced polyester felt as the substrate, and is covered with isolation materials on both sides. It has heat resistance, cold resistance, corrosion resistance, aging resistance, good thermoplasticity, high tensile resistance, high elongation, strong tear resistance, light weight of waterproof layer It is widely used for waterproofing of general industrial and civil buildings due to its simple construction and operation.
