“…Thermoplastic silicone polyurethane elastomer (TPSiU) is a copolymer which is obtained by silicone-modified thermoplastic polyurethane. Due to the introduction of silicone segments in the polyurethane structure, the Si-O bond and polysiloxane as the main body give TPSiU good flexibility and better heat resistance [60]. Therefore, compared with TPU, TPSiU has a better toughening effect on PLA on the one hand, and better heat resistance on the other hand.…”

The melt blending of polylactic acid (PLA) and thermoplastic silicone polyurethane (TPSiU) elastomer was performed to toughen PLA. The molecular structure, crystallization, thermal properties, compatibility, mechanical properties and rheological properties of the PLA/TPSiU blends of different mass ratios (100/0, 95/5, 90/10, 85/15 and 80/20) were investigated. The results showed that TPSiU was effectively blended into PLA, but no chemical reaction occurred. The addition of TPSiU had no obvious effect on the glass transition temperature and melting temperature of PLA, but slightly reduced the crystallinity of PLA. The morphology and dynamic mechanical analysis results demonstrated the poor thermodynamic compatibility between PLA and TPSiU. Rheological behavior studies showed that PLA/TPSiU melt was typically pseudoplastic fluid. As the content of TPSiU increased, the apparent viscosity of PLA/TPSiU blends showed a trend of rising first and then falling. The addition of TPSiU had a significant effect on the mechanical properties of PLA/TPSiU blends. When the content of TPSiU was 15 wt%, the elongation at break of the PLA/TPSiU blend reached 22.3% (5.0 times that of pure PLA), and the impact strength reached 19.3 kJ/m2 (4.9 times that of pure PLA), suggesting the favorable toughening effect.

“…Attempts have been carried out to produce adhesives with better adhesion and mechanical properties at higher temperature, i.e. the heat resistance of the polyurethane adhesive has been improved (Ambuken et al, 2014;Chen et al, 2013;Takeichi et al, 2002). Different kinds of additives, nanoparticles and chain extenders have used to enhance mechanical and adhesion properties of the adhesives at higher temperature.…”

Purpose Presently, a wide range of polyurethane adhesives can be obtained using different kinds of polyols and isocyanates. However, the applied temperature of the polyurethane adhesive is not more than 80°C. The film of polyurethane adhesive will be softened and deformed when its applied temperature is more than 100°C. Thus, the mechanical property of the polyurethane adhesive is decreased clearly, which limits its further application. The purpose of the study is to improve the heat resistance of polyols, especially polyester polyols and its resultant polyurethane adhesives. Design/methodology/approach The more rigid benzene ring is introduced into the polyester polyols to improve the heat resistance of its resultant polyurethane adhesive. Findings The more rigid benzene ring has ben introduced into the polyester polyols and the heat resistance of its resultant polyurethane adhesive is improved. Originality/value The polyester polyols with more rigid benzene ring have been prepared successfully by the vacuum melting method when diethylene glycol, neopentyl glycol, 1,6-hexanediol, ethanediol, isophthalic acid, terephthalic acid, sebacic acid and adipic acid are used as raw materials and tetra-isopropyl titanate is adopted as the catalyst.

A series of polyurethane (PU) composites, which could be used as damping materials, with different contents of hydroxyl silicone oil were successfully prepared in this study. The damping and mechanical properties, thermal stability, and molecular groups of the PU composites were characterized by dynamic mechanical analysis, electronic tensile analysis, thermogravimetric analysis, and Fourier transform infrared (FTIR) spectroscopy, respectively. The surface morphology was also observed via scanning electron microscopy (SEM). FTIR spectroscopy showed that the hydroxyl silicone oil was embedded in the PU. The soft and hard segments of the PU composites appeared thermodynamically incompatible and showed microphase separation, as shown by the SEM pictures. The PU composite with 8% hydroxyl silicone oil was found to possess the best synthetic properties among these composites. The maximum values of tan δ were 0.376, 0.561, and 0.573 at 1, 10, and 20 Hz, respectively. The temperature range for the use of damping materials becomes wider at 1 Hz. Frequencies of 10 and 20 Hz might suitable surroundings for the application of damping materials. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 47579.
