Abstract
(EN)
[Problem] To provide a fibrous cellulose composite resin having exceptional strength, a method for producing the same, and a resin-reinforcing material having an exceptional resin-reinforcing effect even if dried. [Solution] This fibrous cellulose composite resin includes a resin and a mixture of fibrous cellulose and a dispersant. Some or all of the fibrous cellulose includes fine fibers. The dispersant is a carboxylic acid and/or a glycerin. The average particle size of the mixture is 500 μm or less. To obtain the composite resin: the dispersant is mixed with a slurry of fibrous cellulose to form a mixture; the mixture is dried and crushed to form a powder, which is then kneaded with the resin; fine fibers are used as some or all of the fibrous cellulose; a carboxylic acid and/or a glycerin is used as the dispersant; and the powder is crushed to an average particle size of 500 μm or less.

Le problème décrit par la présente invention est de fournir une résine composite de cellulose fibreuse ayant une résistance exceptionnelle, son procédé de production, et un matériau de renforcement de résine ayant un effet de renforcement de résine exceptionnel même s'il est séché. La solution selon l'invention porte sur une résine composite de cellulose fibreuse qui comprend une résine et un mélange de cellulose fibreuse et d'un dispersant. Une partie ou la totalité de la cellulose fibreuse comprend des fibres fines. Le dispersant est un acide carboxylique et/ou une glycérine. La taille moyenne de particule du mélange est de 500 µm ou moins. Pour obtenir la résine composite : le dispersant est mélangé avec une bouillie de cellulose fibreuse pour former un mélange ; le mélange est séché et broyé pour former une poudre, qui est ensuite malaxée avec la résine ; des fibres fines sont utilisées comme partie ou totalité de la cellulose fibreuse ; un acide carboxylique et/ou une glycérine est utilisé en tant que dispersant ; et la poudre est broyée jusqu'à une taille moyenne de particule de 500 µm ou moins.
