Abstract

Composition and binding properties of acetic acid lignins obtained at oxidative catalytic delignification of different types of plant biomass (softwood, hardwood, wheat straw) in the medium: acetic acid - hydrogen peroxide - water - sulfuric acid catalyst were compared. Obtained acetic acid lignins have high concentration of reactive oxygen-containing functional groups, therefore they can be used as low-toxic binding agent for production of wood panel materials with good strength characteristics. The influence of lignin nature, its content in lignin/wood blend and conditions of pressing on the bending strength and water-resistance of obtained wood panel materials was studied. Optimal technological parameters for manufacture of strong and water steady wood panels were found.
