Water-based thermoplastic styrene butadiene rubber SBS latex bitumen modifier and modified styrene butadiene latex have obvious differences in composition, characteristics and application fields.

1. In terms of composition, water-based thermoplastic styrene butadiene rubber SBS latex bitumen modifier consists of solution A and soap solution. Solution A contains thermoplastic styrene butadiene rubber, organic solvent and surfactant; soap solution contains water, natural polysaccharide polymer, surfactant and electrolyte. The initiator of modified styrene butadiene latex is a redox system initiator, including water-soluble and oil-soluble redox initiators, emulsifiers include alkyl aryl sulfonic acid alkali metal salts, etc., and various additives such as electrolytes and chelating agents can be added as needed.

2. In terms of characteristics, the use of water-based thermoplastic styrene butadiene rubber SBS latex bitumen modifier simplifies the production process of thermoplastic styrene butadiene rubber SBS modified bitumen, saves equipment investment, avoids material aging, and the modified bitumen obtained has stable performance and is not easy to segregate. No special equipment is required to produce modified bitumen, the processing method is simple, and the production cost is low. Modified styrene butadiene pyridine latex is a thermosensitive copolymer latex. Compared with the existing latex for non-woven fabric impregnation, it is not necessary to add a thermosensitizer to the latex before impregnation to obtain a thermosensitive effect.

3. In terms of application areas, water-based thermoplastic styrene butadiene rubber SBS latex bitumen modifier can be used for micro-surfacing construction, road construction materials of normal temperature modified bitumen mixtures, bridge deck waterproofing materials and roof waterproofing materials of water and modified emulsified bitumen, etc. Modified styrene butadiene pyridine latex is particularly suitable for non-woven fabric impregnation to manufacture imitation leather and artificial leather base fabrics.
