“…As expected, BIEP-ETA is well soluble in waterborne polyurethane dispersions and its addition did not cause demulsification of WPU dispersions. From Figure 2 a, it can be clearly seen that all dispersions are light blue translucent, and the obvious “Tyndall effect” phenomenon can be observed when the laser beam passes through the dispersion, indicating that the WPU/FRs dispersions are stable colloid with particle sizes ranging from 1 nm to 100 nm [ 24 ]. Even after centrifugation test, no precipitation was found, which confirms that all the WPU dispersions can be stably stored for more than half a year.…”

Waterborne polyurethanes (WPUs) have attracted great interest owing to their environmentally friendly properties, and are wildly applied in production and daily life. However, waterborne polyurethanes are flammable. Up to now, the challenge remains to prepare WPUs with excellent flame resistance, high emulsion stability, and outstanding mechanical properties. Herein, a novel flame-retardant additive, 2-hydroxyethan-1-aminium (2-(1H-benzo[d]imidazol-2-yl)ethyl)(phenyl)phosphinate (BIEP-ETA) has been synthesized and applied to improve the flame resistance of WPUs, which has both phosphorus nitrogen synergistic effect and the ability to form hydrogen bonds with WPUs. The WPU blends (WPU/FRs) exhibited a positive fire-retardant effect in both the vapor and condensed phases, with significantly improved self-extinguishing performance and reduced heat release value. Interestingly, thanks to the good compatibility between BIEP-ETA and WPUs, WPU/FRs not only have higher emulsion stability, but also have better mechanical properties with synchronously improved tensile strength and toughness. Moreover, WPU/FRs also exhibit excellent potential as a corrosion-resistant coating.

“…SBS swelling process was described as follows: at room temperature, the SBS toluene solution was prepared in the wide mouth bottle with the mass ratio (toluene:SBS, T/S) of 3.5 : 1, 3.0 : 1, 2.5 : 1, 2.0 : 1, and 1.5 : 1, sealed and preserved (preventing toluene volatilization), and swelled for 24 h. During this period, the swelling status is continuously observed, and the swelling of the SBS in toluene was observed by the Tyndall effect. e called Tyndall effect is an optical phenomenon that when a light beam passes through a colloid, the suspended particles in the path will scatter the light, enabling a beam of light to become visible [14,15]. is effect makes it possible the qualitative comparison of dispersion stability for SBS solution due to its colloidal nature.…”

Polymer modified asphalt emulsion (PMAE) has recently been proven to be one of the most effective methods to overcome the common distress of asphalt surface treatments, such as abrasion, rutting, ravelling, and poor durability. Because of the limited research studies about the preparation of PMAE using SBS latex, a new method to prepare SBS latex was developed and the feasibility of using it in preparing SBS latex modified asphalt emulsion (SBS-LMAE) was verified in this study. The optimized swelling parameters for linear SBS solutions were swelling 24 h at the temperature of 50°C with the toluene/SBS (T/S) mass ratios of 2.5 : 1 to 2.0 : 1 which was determined according to the analysis of viscosity and Tyndall effect. After that, the SBS latex with favorable dispersivity and stability was successfully fabricated with the T/S ratio of 2.0 : 1. At last, the well-specified SBS-LMAE was prepared using the fabricated latex and tested for its conventional performances and microstructure. The results show that the SBS-LMAE samples all meet the main requirements of PMAE for microsurfacing and possess appropriate uniformity and stability.
