Title:
PRODUCTION METHOD FOR READILY DISPERSIBLE CELLULOSE COMPOSITION, READILY DISPERSIBLE CELLULOSE COMPOSITION, CELLULOSE DISPERSION RESIN COMPOSITION, AND PRODUCTION METHOD FOR WATER-BASED DISPERSANT FOR CELLULOSE
Document Type and Number:
WIPO Patent Application WO/2015/152189
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide technology for facilitating the dispersion of cellulose within a hydrophobic substance such as a resin without performing nano-cellulose surface modification or the like by using a simple and effective method to treat cellulose (which is a hydrophilic substance) with a polymer dispersant that was developed for dispersing a fine hydrophobic substance such as a pigment in a system in which water is the main medium. This objective is achieved by: a production method in which a polymer dispersant that has a block copolymer structure that includes a segment (A) that has resin affinity and a segment (B) that has cellulose-adsorbing properties is dissolved in a hydrophilic organic solvent solution, a surfactant is added to the result, a water-based dispersant that contains the polymer dispersant is subsequently produced by adding water, and the obtained water-based dispersant is added to cellulose that is in a hydrous state or a dry state in order to obtain a readily dispersible cellulose composition; a production method for the water-based dispersant that is used in the aforementioned production method; a readily dispersible cellulose composition; and a cellulose dispersion resin composition that uses the readily dispersible cellulose composition.
