Temperature Storage

Styrene-butadiene-styrene tri-block copolymer (SBS) modified asphalts are usually unstable during high-temperature storage, which presents an obstacle to their application. In this paper, SBS modified asphalts with improved high-temperature storage stability were prepared by incorporating carbon black (CB) into the SBS compounds. The effect of CB on the high-temperature storage properties, dynamic rheology, mechanical properties (softening point, viscosity etc.) and the morphologies of the modified asphalts were studied. It was found that the ratio of SBS to CB in the compound had a great effect on the high-temperature storage behavior. The modified asphalts were stable when the ratio of SBS/CB was around 2. CB had almost no effect on the dynamic rheology or the mechanical properties of the modified asphalts. The improvement in high-temperature storage behavior could be caused by decreasing the density difference and improving the compatibility between SBS and asphalt.

In this reported work, thermoplastic polyurethane (TPU) was used as a reactive polymer modifying agent to prepare a modified-asphalt, using a high-speed shearing method. Physical performance tests of the TPU-modified asphalt were conducted before and after short-term aging, and the aging resistance was examined by the change in materials properties. In addition, low-temperature rheological properties, thermal properties, the high-temperature storage stability, and the aging mechanism of TPU-modified asphalt were also investigated. The results showed that the addition of TPU improved the aging resistance of base asphalt, which was evidenced by the increased penetration ratio and decreased softening point of the asphalt, after aging. Similarly, Fourier Transform infrared (FTIR) spectroscopy results verified that TPU improved the asphalt aging resistance. It was found that the TPU functional groups played a role in improving thermal properties, high-temperature storage stability, and in the dispersion of modified asphalt.

Abstract The objective of this study was to establish a method for detecting fatty acid esters of chloropropanols [including 2-monochloropropane-1,3-diol (2-MCPD) ester and 3-monochloropropane-1,2-diol (3-MCPD) ester] in infant milk powder using isotope dilution and GC-MS. The fat fraction in infant milk powder samples was extracted and treated with sodium methylate–methanol to cleave the ester bonds of the 2- and 3-MCPD esters. The resultant 2- and 3-MCPDs in the samples were purified with matrix solid-phase liquid–liquid extraction and derivatized with heptafluorobutyryl imidazole for GC-MS analysis. Standard samples of deuterium isotope–labeled 2- and 3-MCPD palmitic acid double esters and stearic acid double esters were used as the internal standards. We also detected 2- and 3-MCPD ester contents in 88 commercial samples of infant formula milk powder using this system. The detection system we established showed a good linearity of 2- and 3-MCPD ester contents in serially diluted standard solutions within the concentration range 25−1000 μg/L, with r2 > 0.9995 and an LOD of 30 μg/kg for both of the MCPD esters. The recoveries of the two MCPD esters spiked at 25, 50, 100, and 200 μg/kg in blank infant formula milk ranged from 98.2 to 110.5%, with RSDs <4.8%, suggesting good accuracy and reliability of this method. In the 88 commercial infant formula milk powder samples, the mean content of 2-MCPD ester was 41 μg/kg (0–52 μg/kg) and that of 3-MCPD was 185 μg/kg (0–316 μg/kg). Based on these results, we estimated the exposure levels of the two MCPD esters in infants fed on formula milk, and the results indicate potential health risks of consuming formula milk products contaminated by the two MCPD esters.
