Influence of Alkaline Lignin and Degradation Products of Polyurethane Foam on Structure and Performance of Polyurethane Foam Composite
摘要
Abstract
In order to study the influence of alkaline lignin and degradation products of polyurethane foam ( DPPUF) on structure and performance of polyurethane foam composites (PUF), the reticulated polyurethane foam composites were prepared by using alkaline lignin and DPPUF as raw materials. The FT-IR results showed that compatibility of alkaline lignin and reticulated polyurethane increased due to the existence of strong hydrogen bonding association. SEM analysis indicated that addition of the alkaline lignin and DPPUF could impact the microstructures of PUF. In addition, compression modulus of PUF and the DPPUF increased with the increase of alkaline lignin and reached 146.44 MPa. However, the compression modulus of PUFs would decrease after the introduction of DPPUF and reached 101. 59 MPa. Without the alkaline lignin and the DPPUF, the compression modulus of PUF was 108. 53MPa. The thermal conductivity of product with the renewable polyurethane foam is 0.0325 W/( m o K) while the thermal conductivity of product without the renewable polyurethane foam is 0.022 6 W/( mo K). This showed that the renewable polyurethane foam decreased the thermal insulating property of PUF.关键词
