Abstract
Modified soy protein adhesives are provided which have increased bonding abilities. The adhesives are prepared by forming a dispersion of soy protein, water, and a modifier selected from two classes of modifiers. The preferred modifiers are urea, sodium dodecylbenzene sulfonate, sodium dodecyl sulfate, and guanidine hydrochloride. The resulting dispersion is stirred, freeze-dried, and milled into a powder to be stored until use. The adhesives of the invention have superior bonding qualities while being safe for the environment. The urea-modified, GH-modified, SDS-modified, and SDBS-modified soy protein adhesives have higher water resistance than non-modified soy protein adhesives.
