Abstract:
An apparatus for continuously producing chemically-modified cellulose, the apparatus having a first mechanism for transporting a fine-powder cellulose fiber starting material and a hydrophobizing chemical substance, a specific extruder, a solvent tank connected to the extruder, and a dryer connected to the solvent tank, and a method for continuously producing chemically-modified cellulose, the method having a step of washing, in the solvent tank, chemically-modified cellulose having been produced out of the fine-powder cellulose fiber starting material and the hydrophobizing chemical substance in the extruder, and then drying the chemically-modified cellulose in the dryer, in order to remove any unreacted hydrophobizing chemical substance.

Claim (Index 19):
A method for continuously producing a cellulose composite resin, the method comprising:\n a first step of introducing a fine-powder cellulose fiber starting material and a hydrophobizing chemical substance into a first extruder having a temperature raising mechanism, a pressure raising mechanism and a degassing mechanism, and having a screw piece for kneading, melting the hydrophobizing chemical substance and kneading the hydrophobizing chemical substance and the cellulose, and further allowing the same to react, in order to yield chemically-modified cellulose; a second step of discharging the chemically-modified cellulose from the first extruder, introducing the chemically-modified cellulose into a solvent tank and dispersing the chemically-modified cellulose in an organic solvent, in order to yield a fluid dispersion, and thereafter injecting the fluid dispersion into a dryer connected to the solvent tank, and drying the fluid dispersion, in order to separate the chemically-modified cellulose from the organic solvent; and a third step of mixing the dried chemically-modified cellulose with paraffin, and thereafter kneading the mixture and the thermoplastic resin by introducing the same into a second extruder having a temperature raising mechanism, a pressure raising mechanism and a degassing mechanism, and moreover having a screw piece for kneading.
