Preparation Technique and Property Evaluation of Flame-Retarding/ Thermal-Insulating/Puncture-Resisting PU Foam Composites

摘要

In this study, flame-retarding property of PU foam was realized by compounding with flame-retarding nonwovens in order to stop flame burning and spread. Followed with global warming, thermal-insulating materials are also used inside of building for energy conservation. This article presents preparation technique and property evaluation of PU composite board composed of composite nonwovens and PU foam by integrating foaming process. By optimization of composite nonwoven, effects of foam density and nonwoven composition on flame-retarding and thermal-insulating properties were discussed. Puncture resistance property of composite board was also investigated for resisting against sharp-object impacts. The resultant composite board would be applied as partition materials in future building decoration.
