| description | The present invention relates to starch-based adhesive compositions comprising microfibrillated cellulose ("MFC"). In addition to microfibrillated cellulose, these adhesive compositions comprise at least one starch and/or at least one starch derivative. The adhesive compositions have a reduced amount of caustic soda vis-a-vis adhesive compositions that do not comprise MFC as an additive. Borax or boric acid (or any derivative thereof) may be partially or fully replaced with microfibrillated cellulose, wherein MFC (contrary to borax) surprisingly does not significantly affect the gel temperature of the overall adhesive.
La présente invention concerne des compositions adhésives à base d'amidon comprenant de la cellulose microfibrillée (« MFC »). En plus de la cellulose microfibrillée, ces compositions adhésives comprennent au moins un amidon et/ou au moins un dérivé d'amidon. Les compositions adhésives comportent une quantité réduite de soude caustique par rapport à des compositions adhésives qui ne comprennent pas de MFC comme additif. Le borax ou l'acide borique (ou un dérivé quelconque de celui-ci) peut être remplacé partiellement ou complètement par de la cellulose microfibrillée, la MFC (contrairement au borax) n'affectant pas, de manière surprenante, la température de gel de l'adhésif global. |
