Title
(EN) COATING COMPOSITION COMPRISING HYDROLYSED WHEAT PROTEINS
(FR) COMPOSITION DE COUCHAGE COMPRENANT DES PROTÉINES DE BLÉ HYDROLYSÉES
Abstract
(EN)
The present invention relates to a paper or cardboard coating composition having a dry matter content of between 45 and 80%, comprising i) binders which include at least one modified starch and one adhesive, ii) one hydrolysed wheat protein having a mean molecular mass of between 7 and 1000 kDa, and iii) a mineral filler, as well as the method for obtaining such a composition. The invention also relates to a method for coating or brightening of paper or cardboard, comprising the steps consisting of i) the provision of a composition according to the invention, and ii) the depositing of said composition on a paper or cardboard substrate and the paper or cardboard coating thus obtained. Finally, the invention relates to the use of a hydrolysed wheat protein in the replacement of latex in a paper or cardboard coating composition.
(FR)
La présente invention concerne une composition de couchage de papier ou de carton ayant une matière sèche comprise entre 45 et 80%, comprenant i) des liants parmi lesquels au moins un amidon modifié et un adhésif ii) une protéine de blé hydrolysée ayant une masse moléculaire moyenne comprise entre 7 et 1000kDa, et iii) une charge minérale ainsi que le procédé d'obtention d'une telle composition. L'invention concerne également un procédé de revêtement ou d'azurage de papier ou de carton comprenant les étapes consistant en i) la fourniture d'une composition selon l'invention, et au ii) dépôt ladite composition sur un substrat en papier ou en carton et le papier ou carton couché ainsi obtenu. L'invention concerne enfin l'utilisation d'une protéine de blé hydrolysée dans le remplacement du latex dans une composition de couchage de papier ou de carton.
