Abstract
An adhesive binder composition containing a urea-formaldehyde resin modified with a modified soy protein, and the use of the binder for preparing wood composites, especially particleboard.
Claims20
A wood composite bonded with an adhesive binder composition comprising a urea-formaldehyde resin and a modified soy protein selected from the group consisting of soy protein modified with saturated and unsaturated alkali metal C8-C22 sulfate and sulfonate salts, soy protein modified with compounds having the formula R2NC(═X)NR2, and blends thereof, said protein provided in an amount of 1 percent to 50 percent by weight of adhesive solids.
A process for making a wood composite comprising applying an adhesive binder composition to a wood material, the adhesive binder composition comprising a urea-formaldehyde resin and a modified soy protein selected from the group consisting of soy protein modified with saturated and unsaturated alkali metal C8-C22 sulfate and sulfonate salts, soy protein modified with compounds having the formula R2NC(═X)NR2, and blends thereof, said protein provided in an amount of 1 to 50 percent by weight of adhesive solids, consolidating said wood material and curing said urea-formaldehyde resin.
