Problems solved by technology

For example, nanofibrillar or microfibrillar cellulose is well known for use as a coating material in papermaking and in the wet end, but is expensive and potentially uneconomical to use in typical wet end applications. bound
[0004] The use of nanofibrillar cellulose or microfibrillar cellulose in the wet end of paper / board manufacturing severely hinders the dewatering of the paper web, thereby adding additional costs when drying or slowing down the paper machine, and if used as a surface treatment agent, nanofibrillar Fibrillar or microfibrillar cellulose exhibits poor coating holdout
[0005] The solubility and delicate nature of this material prevents it from being effectively retained, and when retained, it is generally not effectively applied within the spatial distribution of the paper fiber matrix

Embodiment

[0128] 1. Materials

[0129] base : Standard uncoated 80 gm-2 wood-free copy paper (PlanoJet; Papyrus AB, Sweden).

[0130] mineral material : surface-reacted natural ground calcium carbonate (Omyajet B6606; Omya AG, Oftringen, Switzerland; see figure 1 ); weight median particle size d 50 =2.70μm (Sedigraph5100); specific surface area=56m 2 / g; in the form of an aqueous slurry with a solids content of 50% by weight with respect to the mineral material;

[0131] The mineral material was mixed and diluted with 10 wt% styrene acrylate latex binder (Acronal S360D; BASF, Ludwigshafen, Germany) based on the amount of mineral material to obtain a total solids content of 40 wt%.

Abstract

The present invention relates to a method of producing a coated substrate by providing a substrate, providing at least one mineral material, providing a polysaccharide material comprising one or more polysaccharides, coating the substrate with the at least one mineral material, And coating the resulting pre-coating of mineral material with a gel comprising one or more polysaccharides; the invention also relates to the coated substrate obtained by this method and its use.

Description

technical field [0001] The present invention relates to a method for producing a coated substrate as well as the coated substrate obtained by this method and its use. Background technique [0002] It is a continuing goal to improve the properties of certain substrates, such as in papermaking, to provide paper with improved surface properties, such as in terms of surface smoothness and uniformity, and structural stability. [0003] Significant stiffness advantages can be achieved, for example, by using polysaccharides as fillers or coatings. For example, nanofibrillar or microfibrillar cellulose is well known for use as a coating material in papermaking and in the wet end, but is expensive and potentially uneconomical to use in typical wet end applications. bound. [0004] The use of nanofibrillar cellulose or microfibrillar cellulose in the wet end of paper / board manufacturing severely hinders the dewatering of the paper web, thereby adding additional costs when drying or ...
