  • Patent number: 9845397
    Abstract: A method for producing a binder resin by a reaction of a cellulose derivative, a polyvinyl acetal, and a bonding agent that has in the molecule at least two functional groups that can react to hydroxyl groups in the polyvinyl acetal and the cellulose derivative. In the production method, the content of the bonding agent is at least double the molar quantity of whichever has the greater number of moles between the polyvinyl acetal and the cellulose derivative. The produced binder resin is favorable in a coating paste such as a conductive paste, and causes an improvement in film quality such as the smoothness and denseness of a coating film formed by the paste.

  • Patent number: 9822241
    Abstract: Provided herein is a cellulose nanofiber that can be easily combined with a compound having a reactive double-bond group and that can provide a molded article which contains only a small amount of an uncured material that acts as a plasticizer in a molded product, using a simple producing method that does not require any process involving solvent displacement or solvent removal. A high-strength resin composition or molded body prepared by using the cellulose nanofiber is also provided. In refining cellulose in the presence of a compound having a reactive double bond and a hydroxyl value of 200 KOHmg/g or more, the cellulose has a moisture content of 4 to 25 parts by mass with respect to 100 parts by mass of the amount of the cellulose converted on the assumption that the percentage moisture of the cellulose is 0%.

  • Patent number: 9617459
    Abstract: This invention relates to water-based well drilling fluids. It has been found that cellulose based particles, which comprise cell wall material and their networks of cellulose based fibers and nanofibrils can be used to produce suspensions having viscosity and rheological properties particularly suitable for use as a drilling fluid. It is assumed that the organization of the cellulose fibrils, as it exists in the parenchymal cell walls, is at least partly retained in the cellulose based particles of the invention, even though part of the pectin and hemicellulose is removed there from. Breaking plant-based pulp down into this kind of cellulose based particles involves fewer and gentler processes than to break the pulp down further into cellulose nanofibrils, and therefore the present cellulose based particles can be produced much faster and at lower cost than completely unraveled cellulose nanofibrils.
