Quality detection method of refined PLAH composite plasticizer

PendingCN122330076ANon destructivePlasticizer
This invention discloses a quality testing method for refined PLAH composite plasticizers. By integrating Raman spectroscopy-attenuated total reflectance infrared dual-spectral fusion, simultaneous thermorheological characterization, accelerated migration micro-model testing, and a multi-dimensional index model, this method overcomes the shortcomings of existing technologies that only detect chemical content, cannot reflect functional performance, and lack rapid evaluation capabilities. This method achieves integrated and rapid detection of molecular structure matching, phase stability, migration risk, and long-term performance of refined PLAH composite plasticizers, with a total testing cycle of ≤8 hours and a correlation between the test results and actual application performance ≥0.92. This method requires no complex pretreatment and combines the advantages of both destructive and non-destructive testing, making it suitable for online quality control in industrial production, warehousing acceptance, and application performance prediction. It provides key technical support for the optimization of the refining process and quality control of composite plasticizers for bio-based polylactic acid (PLA) materials.
