Problems solved by technology

This method has many disadvantages: first, for large reactors, high-viscosity prepolymers require extremely high dispersion power, and even instantaneous high current may cause the machine to trip or the circuit to burn out, requiring high-power power supply equipment, Large investment, high energy consumption, and high production cost; secondly, the high-speed disperser uses a dispersing disc, which cannot effectively shear all the resin prepolymers in the kettle, and some resin prepo

Abstract

The invention provides an intermittent ultrasonic emulsification device for water-based resin. The device comprises an emulsification kettle, a high-speed dispersion machine, a base, a bracket and a control device, wherein the lower part of a reaction kettle is provided with a discharge port and a cooling jacket; a kettle cover is mounted at the upper end of the reaction kettle; a feed port and anoverflow port are formed in the kettle cover; and the high-speed dispersion machine is fixedly mounted on the kettle cover. The device is characterized in that an energy-gathering ultrasonic generator is fixedly mounted on the kettle cover, a probe of the energy-gathering ultrasonic generator extends into an inner cavity of the reaction kettle, and a divergent ultrasonic generator is mounted on the side wall of the reaction kettle. The device has the advantages of high production efficiency, good product quality, low equipment investment and energy consumption, low product production cost andthe like and is an emulsifier applicable to waterborne polyurethane resin.

Description

technical field [0001] The invention relates to a water-based resin ultrasonic emulsification device. The invention is suitable for an emulsifier of waterborne polyurethane resin. Background technique [0002] In the production process of polymer resin materials, the emulsification process is the most important process in the product production process. At present, the existing resin emulsification device basically uses a reaction kettle or a separate dispersion kettle, and a high-speed disperser is installed in the reaction kettle or a separate dispersion kettle for emulsification. Larger dispersion kettles also need to add anchor or frame type Stir to increase the mixing efficiency of the material during shearing. There are two methods of resin emulsification: water and oil or oil and water. The shearing action of the high-speed disperser makes the resin in the oil phase and the water phase undergo intense shearing and mixing to form latex particles with double ionized l...
