Cellulose-reinforced high mineral content products and methods of making the same

摘要: This invention relates to a novel method prepare aqueous furnishes useful as feedstock in the manufacture of very high-mineral content products, particularly paper sheets having mineral filler up 90% that display required physical properties for intended applications. The comprise fibrillated long fibres/mineral fillers mixed with anionic acrylic binders and co-additives, presence or absence cellulose fibrils. fibres fibrils provide high surface area greater fixation reinforcement backbone network ties all product components together. allow rapid strong particles onto surfaces when mixing is conducted at temperatures higher than glass transition temperature (Tg) binder. To formulation can be added other functional process additives commonly used paperboard packaging by single, multilayer multiply papermaking forming processes. also fabricate shaped items known pulp moulding formulations excellent retention drainage during fabrication.
