Abstract

Abstract: Phenolized humic acid (PHA) was used in the preparation of PHA-phenol-formaldehyde foam. The structure and properties of the foam were characterized using Fourier infrared spectroscopy, thermogravimetric , nitrogen adsorption, and impact testing. When the loading of PHA was 40 wt%, an impact strength of 5.7 kJ/m2, a compression strength of 0.33 MPa, an oxygen index of 47 %，a thermal conductivity coefficient of 0.038 W/（m·K）, and a carbon residue at 400 ℃ of 79.1 % were obtained.

Key words: phenol resin, phenolized humic acid, foam, thermal conductivity
