Abstract

PURPOSE:To make it possible to use a polyisocyanate in combination to reduce amt. of formaldehydre released from a particle board and to improve strength and water resistance of the particle board, by using a specific urea resin or urea-melamine resin as an adhesive. CONSTITUTION:In obtaining a particle board by molding wooden chips with an adhesive under heating and pressing, a urea resin or a urea-melamine resin whose methanol content is less thin 1wt.% is used in combination with an emulsifiable polyisocyanate as this adhesive. Methanol not only reacts with polyisocyanate, but also lowers emulsifying stability of emulsifiable polyisocyanate compound to cause agglomerated sedimentation. If the methanol content is less than 1wt.%, troubles due to methanol can be substantially avoided. The particle board thus obtained contains little amt. of formaldehyde released, has excellent strength under wet condition and exhibits relatively small change when water is absorbed.
