Preparation and Test of Polyurethane Foam Composites with Alkali Lignin/Renewable PUF
The polyurethane foam composite was prepared by alkali lignin and renewable polyurethane foam (PUF). The thermal stability as well as compression property was studied. It was obtained from the TG curve and the DTG curve that the initial decomposition temperatures of polyurethane foam composites with 10% renewable PUF and without renewable PUF were 560.25K and 574.13K,respectively, which showed the renewable PUF affacted the thermal stability of the polyurethane foam composite. The compressive strength (σ10)was from 203kPa to 125 kPa , which were affacted by the dose of the renewable PUF.
