Patent

CA 2599882

The invention relates to a method for sizing a paper product that involves the steps of (a) providing a paper stock system; (b) forming, in the absence of high shearing forces, an aqueous sizing emulsion comprising an alkenylsuccinic anhydride component; (c) submitting the emulsion formed from step b to a post- dilution step in the presence of a cationic component under conditions, in the absence of high shearing forces, that produce a post-diluted emulsion having improved sizing efficacy; (d) adding the post-diluted emulsion to the paper stock; and (e) forming a paper web.

L~invention concerne un procédé d~encollage d~un produit en papier qui implique les étapes consistant à (a) fournir un stock de papier ; (b) former, en l~absence de forces de cisaillement élevées, une émulsion d~encollage aqueuse comprenant un anhydride alcénylsuccinique ; (c) soumettre l~émulsion formée à partir de l~étape b à une étape de post-dilution en présence d~un composant cationique sous des conditions, en l~absence de forces de cisaillement élevées, qui produisent une émulsion post-diluée ayant une efficacité d~encollage améliorée ; (d) ajouter l~émulsion post-diluée au stock de papier ; et (e) former une feuille de papier continue.
