Product introduction:
SBR granular high-ductility asphalt modifier is a polymer produced by polymerizing styrene and butadiene into styrene-butadiene latex through low temperature (5 ° C) emulsion, and then appropriately grafting other monomers according to the characteristics of highway SBR ll modified asphalt. Elastic material, is a product with 100% independent intellectual property rights independently developed by Xianyuan Technology. At present, domestic SBR ll modified asphalt is mostly produced by block glue method or powder method. There are many difficult problems such as cumbersome glue cutting process, long swelling time, and fast index decay after thermal storage. SBR high-ductility asphalt modifier has completely subverted the current situation of domestic highway SBR ll modified asphalt production. Compared with block glue, SBR high-ductility asphalt modifier has many advantages such as less addition, no need to cut glue, short dissolution time, and better anti-aging performance. Its internal performance and quality are better than domestic bulk styrene-butadiene rubber. SBR granular high-ductility asphalt modifier is based on SBR styrene-butadiene rubber, adding polymer common material, and strictly controls various performance indicators through advanced scientific and technological production equipment. It is produced finely, giving full play to the role of styrene-butadiene rubber in asphalt modification.
