Abstract

1,252,878. Size; paper. MOBIL OIL CORP. 23 June, 1970 [17 July, 1969], No. 30370/70. Headings D1P and D2B. A paper sizing composition comprises a mixture of an aqueous cationic wax emulsion and an anionic rosin size. The cationic wax emulsion may include petroleum wax, vegetable wax and mineral wax, and the rosin size, may comprise any anionic rosin which has been saponified (either partially or completely) to form a water soluble soap material, e.g. by saponification of abietic acid with an alkali. The rosin size is employed from 5 to 50% and preferably 10 to 35% by weight. The cationic wax emulsion comprises (a) a dispersed phase comprising a petroleum wax; (b) an emulsifying agent comprising an amine salt of an organic acid having 1 to 18 carbon atoms and preferably 1 to 6 carbon atoms, or an inorganic mineral acid, with an amine having 10 to 40, and preferably 20 to 40 carbon atoms; and, if so desired (c) an emulsion modifier comprising an amine having up to 12 carbon atoms and having a molecular weight lower than that of the amino employed for producing the emulsifying agent. The petroleum wax may be modified with polymers, e.g. polyethylene, ethylene-vinyl acetate copolymers. Examples of the organic acid with 1 to 18 carbon atoms are formic acid, acetic acid, propionic acid and butyric acid, and of the inorganic mineral acids are hydrochloric, sulphuric, phosphoric and nitric acids. The acid is employed in an amount sufficient only to react with all of the amine employed for preparing the emulsifying agent. Propylene diamines are used to produce the emulsifying agent and Examples of amines used as the emulsion modifier are dicyclohexylamine, nheptyl-#-amine, n-octylamine, n-dodecylamine, aniline and N-dodecyl 1, 3 propylene #diamine. The emulsion modifier lowers the viscosity and improves the shear stability of the emulsion. The sizing composition is added to paper pulp prior to it being wet-laid to form paper.
