Apparatus for preparing polymer latex resin powder and method of preparing polymer latex resin powder using the same

摘要

Disclosed are an apparatus for preparing a polymer latex resin powder in which an efficiency of mixing of steam, a latex, and a coagulant is increased by introducing a non-continuous screw into a reactor that performs coagulation and aging and thus a moisture content of a slurry is decreased and, accordingly, drying efficiency may be enhanced, and a polymer latex resin powder with excellent color and powder characteristics may be prepared using a decreased amount of coagulant and a method of preparing a polymer latex resin powder by using the same.

主权项

1. An apparatus for preparing a polymer latex resin powder comprising:
a reactor for coagulation of a polymer latex, in which the reactor comprises a hollow reaction tube through which a latex passes, at least one barrel pin protruding from an inner wall of the reaction tube to an inner side of the reaction tube, a rotating shaft extending along a central axis in a longitudinal direction of the reaction tube, and one or more stirrers protruding from an outer surface of the rotating shaft towards the inner wall of the reaction tube, wherein the one or more stirrers comprise a non-continuous screw, wherein, in the non-continuous screw, an inclination angle α of a rotary wing with respect to an axis perpendicular to the rotating shaft is 0.1° to 10°, and wherein the apparatus comprises at least one of a dehydrator and a dryer.
