ABSTRACT:
Novel starch-silicate adhesive compositions are disclosed which are of particular advantage in the manufacture of corrugated board. By the controlled combination of starch, alkali silicate and, optionally, caustic soda and borax it has been found possible to produce useable adhesives having much higher levels of solids content than conventional starch-based adhesives, thereby allowing for lowered energy costs in use of the adhesive formulation to manufacture boxboard, as well as improved product quality. The formulation of starch-silicate adhesives according to the invention allows viscosity, rheological characteristics--in particular gelation temperature--and the speed of "green-bond" formation to be controlled and adapted to the requirements of modern high-speed corrugating equipment.
