Alkaline Aluminosilicate Binder for Gluing Wood Board Materials

Abstract:

Article Preview

Organic adhesive – bonded wood board materials like particleboards, plywood and others are widely used in construction, furniture, car- making, etc. However, all materials made with organic adhesives release non-reacted toxic substances, in particular formaldehyde and phenol, which produce negative effects on human health during production and use. Current trend in wood processing industry is to replace organic binders used as adhesives by inorganic ones. One of such solutions to improve indoor air quality is to replace organic adhesives by inorganic ones and the use of the alkaline aluminosilicate binders of the system R2O-Al2O3-SiO2-H2O is a highly advantageous solution and no need of preliminary treatment of wood. Among disadvantages are the low elasticity. Among disadvantages of these binders restricting their use as adhesives are low elastic properties (high modulus of elasticity, stiffness) of the resulted wood-based products. The paper covers the results of modification of the alkaline aluminosilicate binders to improve properties using specially chosen organic additives – modifiers
