摘要： Herein provided are methods for evaluating cellulose nanofiber dispersions, comprising the steps of: (1) preparing a cellulose nanofiber dispersion; (2) adding a color material into the cellulose nanofiber dispersion; and (3) observing the cellulose nanofiber dispersion to which a colored pigment has been added with a light microscope. The methods allow for easy evaluation of whether or not agglomerates of cellulose nanofibers exist in cellulose nanofiber dispersions, which cannot be visually determined.

摘要： A solid product of a lignin-containing composition can have high dispersibility and heat stability; a solid product of a high performance lignin derivative can be used as a dispersing agent, useful at a construction site, with a concrete, and/or as a premix mixed with a hydraulic composition. A composition can serve as a dispersing agent capable of providing various substances to be dispersed with a thickening property and of enhancing the properties thereof, regardless of the use thereof such as for a hydraulic composition, dye, inorganic or organic pigment, coal-water slurry, agricultural chemical, ceramic, and/or oil drilling mud. The composition includes a lignin sulfonic acid-based compound and a water-soluble compound, or includes a lignin derivative that is a reaction product of a lignin sulfonic acid-based compound with an aromatic water-soluble compound and that satisfies prescribed conditions; and the composition may be a granular product or a liquid product.

摘要： Disclosed herein is method for preparing a masterbatch by dispersing chemically modified cellulose nanofibers having carboxy groups under acidic conditions and then mixing the dispersed cellulose nanofibers with rubber latex. More specifically, the present disclosure provides a method for producing a masterbatch, including: (A) a step of introducing a carboxy group to a cellulose-based raw material to prepare a modified cellulose; (B) a step of carrying out defibration treatment and dispersion treatment of the modified cellulose to prepare a cellulose nanofiber; (C) a step of acidifying the cellulose nanofiber to prepare an acid type cellulose nanofiber; and (D) a step of mixing the acid type cellulose nanofiber and a rubber component. The rubber composition having excellent strength such as tensile strength can be provided by using the obtained masterbatch.
