Disclosed are surfactant-stabilized latex emulsions which can be used as binders in paper coating compositions. Such latex emulsions comprise an interpolymer formed by emulsion polymerizing monomers selected from vinyl esters, e.g., vineyl acetate; ethylene; certain unsaturated mono- and di-carboxylic acid materials such as acrylic acid or maleic anhydride; and certain polyethylenically unsaturated cross-linking co-monomers such as diallyl phthalate. These latex emulsions are stabilized with surfactants which are substantially free of environmentally suspect alkyl phenol ethoxylates (APEs). The paper coating compositions containing latex emulsion binders of this type exhibit especially desirable coating strength as quantified by the Dry Pick Values (as defined herein) which such compositions provide.

Method for improving paper and board's resistance to the penetration of liquids

Номер: US20120138249A1
Автор: Danny C. Alexander, Patrick Sundholm
Принадлежит: Individual

This invention brings a new aspect in papermaking by spraying hydrophobic chemical directly onto the paper surface in the dryer section of the paper machine, as a two-step process where high solids starch is sprayed on the paper to seal the sheet's surface and thereafter the hydrophobic chemical is sprayed on the paper surface. This invention is a completely new method of hydrophobic sizing, spraying a small amount of a suitable hydrophobic chemical on the moving web in the dryer section, instead of adding hydrophobic chemical in the wet-end of the paper machine, or mixing it in with starch at a size press. This invention reduces the amount of hydrophobic chemical used compared to any of the other processes, it simplifies wet-end chemistry, and it puts the hydrophobic sizing exactly where it is needed, on the paper's surface, which in many cases will be a single side of the paper.

A process for manufacturing fiberboard by preparing a fiber slurry mixture including containing cellulose fibers and water then atomizing a liquid bituminous material, such as asphalt. The liquid bituminous material is atomized by mixing it with a pressurized gas, such as compressed air, forming a mist comprising droplets of bituminous material having a diameter between 20 microns and 50 microns. A water spray solidifies the bituminous material droplets thereby forming bituminous particles which fall into the fiber slurry within the spray chamber. From there the slurry is sheared, dewatered, and dried, forming a finished fiberboard.
