New ecological composites based on natural renewable resources

Abstract

The use of the lignin-corundum hybrid fillers for phenolic resins was showed. The very important aspect of the use of lignin for phenolic resin composites is the reduction of phenol emission. The emission of phenol from the phenolic resin-hybrid filler composites were studied by headspace analysis. The physicochemical properties of the new hybrid fillers as well as the thermomechanical properties of the composites with them were examined. The surface properties of hybrid fillers were studied by inverse gas chromatography (IGC). The chemical structure of the new fillers was tested by Fourier transform infrared spectroscopy (FTIR). The dynamic mechanical thermal analysis (DMTA) was used to test the thermomechanical properties of the model composites for the use of abrasive tool production.

Flammability Tests and Investigations of Properties of Lignin-Containing Polymer Composites Based on Acrylates

“…Due to its chemical structure and the presence of different functional groups it can provide additional functionality in composites such as a reinforcing agent, filler, stabilizer, compatibilizer, etc. [ 15 , 16 , 17 ]. Moreover, it could be effectively used as a carbon source in combination with other flame retardants to design the intumescent system for polymeric materials due to its high capability of char formation [ 18 , 19 , 20 , 21 , 22 ].…”
