Abstract

202,432. Masterman, A. T. May 25, 1922. Pulp, adding special substances to; sizing.-In waterproofing paper by the addition to the pulp of an emulsion of resin soap and wax subsequently precipitated on the fibres by alum, the materials are retained in the emulsified condition and a harder and more waterproof product obtained by the addition of a polymerizing agent, e.g. formaldehyde, tannic acid, an alkaline solution of potassium permanganate, chromic acid, &c. Oil may be added to the emulsion and a small quantity of a water-soluble colloid e.g. glue, gum, alkali-casein, &c. The temperature of the pulp is maintained throughout the operation above the melting point of the waterproofing agent employed. In the example given, a size of sodium resinate is dissolved in its own weight of water and heated to 70‹ C. while stirring in one third of its weight of paraffin wax. After emulsification a 40 per cent solution of formaldehyde to the amount of 8-10 per cent of the resin is added, and the temperature allowed to fall to 50‹ C., when gelatine to the amount of 1-2 per cent of the water present is stirred in. The size produced is placed in the heater and the temperature maintained at 45-60‹ C.
