Title (DE) WÄSSRIGE ALKYLDIKETEN-DISPERSIONEN UND IHRE VERWENDUNG ALS LEIMUNGSMITTEL FÜR PAPIER
(EN) AQUEOUS ALKYLDIKETENE DISPERSIONS AND THEIR USE AS SIZE FOR PAPER
(FR) DISPERSIONS AQUEUSES D'ALKYLDICETENE ET LEUR UTILISATION COMME COLLE D'ENCOLLAGE POUR PAPIER
Abstract:
(DE) Wäßrige Alkyldiketen-Dispersionen, die ein Alkyldiketen, kationische Stärke mit einem Amylopektingehalt von mindestens 95 Gew.-% und anionische Dispergiermittel (a) 0,05 bis 1,0 Gew.-% Ligninsulfonsäure, Kondensate aus Naphthalinsulfonsäure und Formaldehyd, sulfoniertes Polystyrol, Salze und Mischungen der genannten Polymeren und (b) 0,05 bis 1,5 Gew.-% Schwefelsäurehalbester von Alkoholen mit mindestens 10 C-Atomen, Mono- oder Diphosphorsäureester von Alkoholen mit mindestens 10 C-Atomen, Schwefelsäurehalbester von alkoxylierten Alkoholen mit mindestens 10 C-Atomen, Mono- oder Diphosphorsäureester von alkoxylierten Alkoholen mit mindestens 10 C-Atomen, C12- bis C30-Alkylsulfonsäuren, Salze und Mischungen der genannten Verbindungen enthalten sowie die Verwendung der wäßrigen Alkyldiketen-Dispersionen als Masseleimungsmittel bei der Herstellung von Papier, Pappe und Karton sowie Hydrophobierung von Cellulosefasern.
(EN) The invention concerns aqueous alkyldiketene dispersions containing an alkyldiketene, cationic starch with an amylopectin content of at least 95 % by wt. and the following anionic dispersants: (a) 0.05 to 1.0 % by wt. of lignin sulphonic acid, condensation products of naphtalene sulphonic acid and formaldehyde, sulphonated polystyrene or salts or mixtures of such polymers and (b) 0.05 to 1.5 % by wt. of sulphuric acid half esters of alcohols with at least 10 C-atoms, mono- or diphosphoric acid half esters of alkoxylated alcohols with at least 10 C-atoms, sulphuric acid half esters of alkoxylated alcohols with at least 10 C-atoms, mono- or diphosphoric acid esters of alkoxylated alcohols with at least 10 C-atoms, C12-C30 alkyl sulphonic acids or salts or mixtures of such compounds. The invention also concerns the use of such alkyldiketene dispersions as bulk size in the manufacture of paper, paperboard and cardboard, as well as in making cellulose fibres water-repellent.
(FR) L'invention concerne des dispersions aqueuses d'alkyldicétène contenant un alkyldicétène, un amidon cationique ayant une teneur en amylopectine d'au moins 95 % en poids et des agents de dispersion anioniques: (a) de 0,05 à 1,0 % en poids d'acide ligno-sulfonique, de produits de condensation de l'acide naphthalène-sulfonique et de formaldéhyde, un polystyrène sulfoné, des sels et des mélanges desdits polymères, et (b) de 0,05 à 1,5 % en poids de semi-esters d'acide sulfurique d'alcools contenant au moins 10 atomes de carbone, des esters d'acide monophosphorique ou diphosphorique d'alcools contenant au moins 10 atomes de carbone, des semi-esters d'acide sulfurique d'alcools alcoxylés contenant au moins 10 atomes de carbone, des esters d'acide monophosphorique ou diphosphorique d'alcools alcoxylés contenant au moins 10 atomes de carbone, des acides alkylsulfoniques C12-C30, des sels et des mélanges desdits composés. L'invention concerne également l'utilisation des dispersions aqueuses d'alkyldicétène comme colle d'encollage de masse pour la fabrication de papier, de carton-pâte et de carton, ainsi que comme agent d'hydrofugation des fibres de cellulose.
