Abstract

The invention provides a water-based resin continuous ultrasonic emulsification device and a using method of the continuous ultrasonic emulsification device. The device comprises an emulsification cavity and a premixing cavity, wherein a first feeding port and a second feeding port are formed in the top of the premixing cavity, a material mixing and stirring device is arranged in the premixing cavity, a discharging port in the bottom of the premixing cavity is connected with a feeding port of the emulsification cavity through a feeding pump, energy-gathered ultrasonic generators are arranged at the top and the bottom of the emulsification cavity, ultrasonic probes of the energy-gathered ultrasonic generators extend into the emulsification cavity, a high-speed dispersion machine is arranged at the top of the emulsification cavity, a dispersion disc of the high-speed dispersion machine is arranged in the emulsification cavity, multiple sets of divergent ultrasonic generators are arranged on the outer wall of the emulsification cavity, and a discharge port valve is arranged at the discharge port of the emulsification cavity. According to the invention, a violent effect between particles is formed between two materials by utilizing a mechanical effect and a cavitation effect of ultrasonic waves, the emulsification process of the materials is completed in a very short time, the continuity of an ultrasonic emulsification device is improved, and the yield and the output efficiency of an emulsified product are improved.

Description

technical field [0001] The invention belongs to the technical field of water-based resin production, in particular to a continuous ultrasonic emulsification device for water-based resin and a use method thereof. Background technique [0002] In the industrial production process, the emulsification process is an important process in the product production process. Ultrasonic emulsification refers to the process of mixing two or more immiscible liquids uniformly to form a dispersed system under the action of ultrasonic energy, and one of the liquids is evenly distributed in the other liquid to form an emulsion. [0003] Now people can accept two mechanisms about phacoemulsification, one is the cavitation mechanism, and the other is the interface instability mechanism. The mechanism of ultrasonic cavitation means that under the action of strong ultrasonic waves, a large number of small bubbles will be generated in the liquid, and the small bubbles will gradually grow and incre...

Problems solved by technology

This method has many disadvantages. First, for large-scale reactors, high-power power supply equipment is required, which requires large investment and high energy consumption; second, the dispersion disc cannot effectively shear all the resin prepolymers in the reactor, which may It will lead to emulsification failure or excessive latex particle diameter and other defects

[0006] At present, the device with better emulsification effect in the field of polymer resin materials is the intermittent ultrasonic emulsification device. The advantages of this device are that the latex particles are smaller, the particle size distribution is better, the emulsion stability is good, the investment is low, and the energy consumption is low. However, This kind of emulsification device has low output and poor continuity. Aiming at this shortcoming, a continuous ultrasonic emulsification device is designed to apply the advantages of the continuous ultrasonic emulsification device to the resin industry to improve production and efficiency.
