【 摘 要 】

The silicone model is an important part in the making of plastic molds. This paper studies the curing kinetics of two-component addition silicone in polyvinyl chloride (PVC) coated skin using the rheological method. Meanwhile, this paper analyzes the components in the PVC coated skin causing the two-component addition silicone not to cure by using infrared spectroscopy, nuclear magnetic resonance, inductively coupled plasma mass spectrometry, and inductively coupled plasma spectrometer. Result shows that phosphorus (P), sulfur (S), Plumbum (Pb), chromium (Cr), mercury (Hg), and arsenic (As), especially P in the PVC coated skin can cause platinum catalyst poisoning.
