Introduction SBS thermoplastic styrene-butadiene rubber SBS (English name: Thermoplastic SBS elastomer) belong to a styrene-based thermoplastic elastomer, a styrene - butadiene - styrene tri-block copolymer (Styrene Butadiene styrene block polymer), known as thermoplastic styrene-butadiene block copolymer or a thermoplastic rubber, referred to as the SBS. SBS both rubber and excellent performance plastics, with good flexibility, low temperature resistance, air permeability, slip resistance to temperature, coloring, electrical insulation properties, processing without curing, can be directly used injection, molding, extrusion, etc. various molding process. The main purpose and characteristics are widely used in asphalt modification, footwear, plastic modification and adhesives industry. Polymer modified: with polyethylene, polypropylene, polystyrene and other plastics modification, improve its physical properties, so that they get a wider range of applications. Adhesive industry: SBS can be used for production of various types of adhesives, especially hot melt pressure sensitive, pressure-sensitive, solvent-based adhesive with strong adhesive, non-toxic, pollution-free characteristics of the system Footwear industry: SBS can be used for production of various grades of leather shoes, hiking shoes, children's shoes, with a comfortable, anti-slippery, breathable, easy to color, etc., since the SBS Without vulcanization process is very simple, and can have a scrap recycling advantages. Asphalt Modified: 3% -15% of SBS in asphalt can improve the low temperature flexing resistance and high-temperature flow properties of asphalt. Asphalt low temperature flex stiff reduce the life of asphalt at low temperatures. Improved high-temperature performance of asphalt can reduce resistance to flow at high temperatures soften the asphalt flowing. SBS is effective in improving the highway, roll life. Recommended manufacturing formula (1) with a dry adhesive soles basic recipe (the amount are in parts by weight) of pure plastic oil CaCO3 PS white carbon black additives antioxidants ordinary 100 70 30 30 ≤5 ≤2 1 translucent 100,703 -5153-521 transparent 10045-500002-3 appropriate amount of process elements: the mixing process is the key, the process temperature generally feed section 140 ℃ -150 ℃, compression section 150 ℃ -170 ℃, are of section 160 ℃ -180 ℃, the die 140 ℃ -150 ℃. Transparent material to consider adding 3-5 parts K resin and the amount of ultraviolet absorber. Reference formula: filling oils, resins, fillers, protectant, release agents, colorants, blowing agents (2) the use of SBS modified bitumen dosage: road bitumen (4% to 6% by weight) Building bitumen modified ( 8% -12% by weight) conditions: We recommend using a colloid mill body and other special machinery, the temperature is about 180 ℃ (3) SBS adhesive SBS presents a two-phase separation structure with a with a good soluble and self-reinforcing, you can add more accessory ingredients, preparation of various, high-performance adhesives, such as: adhesive, adhesive, hot sol.
