Hard Thermosetting Polyurethane Plastic Degradable Test and its Influential Factors

Article Preview

Abstract:

Through the combined mechanical forces of sheer, friction and squeezing, the rigid polyurethane powder particles get certain plasticity. Based on the principles of mechanical and physical methods, an orthogonal test is designed, and then characterization analysis under conditions of different parameters is carried out through ATR-FTIR. The test indicates that when the rotate speed is 2400r/min, test time is 120min and inlet amount is 24g, the carbamic acid ester groups break down at the place of C-O bond and the cross-linked network structure is destroyed, then the best degradation effect is gained. This article provides theoretical basis for the recycle of thermosetting plastic.
