Title (EN) ADHESIVE COMPOSITIONS FOR CORRUGATED BOXES
(FR) COMPOSITIONS ADHESIVES POUR CAISSES EN CARTON ONDULE
Abstract:
(EN) 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.
(FR) L'invention concerne de nouvelles compositions adhésives à base d'amidon et de silicate, qui présentent un avantage particulier dans la fabrication du carton ondulé. En associant de manière contrôlée de l'amidon, un silicate alcalin et, éventuellement, de la soude caustique et du borax, il est possible de produire des adhésifs utilisables ayant une teneur en matières sèches beaucoup plus élevée que les adhésifs amylacés classiques. L'utilisation de la formulation adhésive dans la fabrication de carton pour boîtes diminue ainsi les coûts énergétiques et permet d'obtenir une meilleure qualité. La formulation des adhésifs à base d'amidon et de silicate selon l'invention permet de contrôler la viscosité, les caractéristiques rhéologiques, notamment la température de gélation, et la vitesse de la formation de 'liaisons initiales', et de les adapter aux exigences des machines à onduler ultra-rapides modernes.
