Document Type and Number:
Japanese Patent JP7460329
Kind Code:
B2
Abstract:
Provided are a fibrous cellulose composite resin excellent in strength, a method for producing the same, and a reinforcing material for resins capable of significantly improving resin strength. The fibrous cellulose composite resin includes fibrous cellulose containing microfiber cellulose, a resin, and an acid-modified resin, wherein the microfiber cellulose has an average fiber width of 0.1 µm or larger, an average fiber length of 0.02 to 2.0 mm, and a percentage of fibrillation of 1.0 % or higher, and hydroxyl groups substituted with carbamate groups, and the carbamate groups are ionically bonded to acidic groups of the acid-modified resin. In producing a fibrous cellulose composite resin by defibrating a cellulose raw material into microfiber cellulose and kneading the microfiber cellulose with a resin, the defibrating is performed so that the microfiber cellulose has an average fiber width of 0.1 µm or larger, an average fiber length of 0.02 to 2.0 mm, a percentage of fibrillation of 1.0 % or higher, and hydroxyl groups of the cellulose fibers are substituted with carbamate groups, and an acid-modified resin is added.
