Waterborne polyurethane dispersion synthesis reaction kettle

Abstract

The invention discloses a waterborne polyurethane dispersion synthesis reaction kettle, and relates to the technical field of reaction kettles. The waterborne polyurethane dispersion synthesis reaction kettle comprises a reaction kettle box body, a stirring rod and a cover plate, wherein a spring groove is formed in the position, close to the lower portion, in the reaction kettle box body, a first telescopic spring is fixedly installed on the inner side of the spring groove, a first sliding groove is formed in the position, located above the spring groove, of the interior of the reaction kettle box body, a plurality of stirring blades are fixedly installed on the outer side surface of a stirring rod, a first gear is fixedly installed at the upper end of the stirring rod, and a first rotating seat is rotationally connected to the position, close to the lower portion, of the outer side surface of the stirring rod. According to the invention, by arranging a motor, a first rotating shaft can be controlled to rotate so as to control a plurality of stirring blades to rotate, and by arranging a cam, the cam intermittently flaps a stirring rod, so that the stirring rod rotates and reciprocates up and down at the same time, the stirring and mixing efficiency is greatly improved, and the synthesis time of a water-based polyurethane dispersoid is shortened.

Description

technical field [0001] The invention relates to the technical field of reactors, in particular to an aqueous polyurethane dispersion synthesis reactor. Background technique [0002] The broad understanding of the reactor is a container with physical or chemical reactions. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are realized. The reactor is widely used in petroleum, chemical, In the fields of rubber, pesticides, dyes, medicine and food, it is a pressure vessel used to complete vulcanization, nitration, hydrogenation, alkylation, polymerization, condensation and other processes, such as reactors, reaction pots, decomposition pots, polymerization kettles, etc.; material Generally, there are carbon-manganese steel, stainless steel, zirconium, nickel-based (Hastelloy, Monel, Inconel) alloys and other composite materials. Water-based polyurethane dispersions...
