Lignin : a promising partial replacement of phenol for making value added composite for building applications - Vol.28(3), Jul-Sep - Pune NICMAR 2013 - 51-59p.
The paper describes the synthesis of lignin formaldehyde that will help in potential reduction in use of phenol. The physical and chemical properties of lignin phenol formaldehydes resin obtained are studied by using FTIR of lignin extract, lignin phenol and phenol formaldehyde for main groups and reactions taking place during conversion. Physical properties of prepared composite using the lignin formaldehyde resin for density, moisture content, water absorption, tensile strength etc. were determined with the physical properties of lignin formaldehyde for viscosity using Brookfield Apparatus. The wood particle-lignin composite was found to be a good and sustainable economic alternative to the composites produced by using phenol formaldehyde along with industry waste. A composite made by using the lignin formaldehyde with eucalyptus wood particles was found to be better when compared to the composites made by using phenol formaldehyde resin in terms of mechanical properties including density, moisture content, tensile strength, water absorption and swelling in water.
