FIBROUS RESIN REINFORCING AGENT AND METHOD FOR PRODUCING SAME, AND RESIN COMPOSITION USING SAME

摘要

[Problem] To provide a method for producing a fibrous resin reinforcing agent whereby cellulose fiber and polylactic acid are more readily composited, the cellulose fiber in the resulting resin composition has high uniform dispersibility, and the impact resistance of a molded body is significantly improved. [Solution] A fibrous resin reinforcing agent in which a hydrophilic additive is dissolved in an aqueous dispersion of refined cellulose fiber to prepare a suspension, and in which the refined cellulose fiber obtained by removing moisture from the suspension is uniformly dispersed, wherein the impact resistance can be dramatically improved by the addition of the reinforcing agent to the polylactic acid.
