A Study on Organic Modification of Damping Properties of Polyurethane Materials for Building
The damping property of viscoelastic dampers is mainly based on the shear hysteretic behavior of viscoelastic materials,so as to reduce the dynamic response of viscoelastic materials.Therefore,the viscoelastic damping properties of viscoelastic materials greatly affect the viscoelastic dampers.At present,viscoelastic materials mainly use rubber materials,but in this thesis,the excellent properties of polyurethane elastomer materials are used to replace rubber materials and applied to viscoelastic dampers.However,pure polyurethane elastomer damping properties are related to poor performance,so it should be modified.Based on the research of inorganic filler-modified polyurethane elastomer,the research group modified the three kinds of organic chemicals with hydroxyl silicone oil,HTPB liquid rubber and epoxy resin E-51,in the low frequency region of 0.025Hz-1.5Hz through the dynamic load test machine to test the damping performance.
