Abstract
The utility model relates to the technical field of watercraft acrylic resin emulsion production equipment, and provides an emulsion synthesizing reaction kettle. A stirring device is arranged inside the reaction kettle, a material inlet is formed in the top of the reaction kettle, a material outlet is formed in the bottom of the reaction kettle, and a temperature-adjustment medium clamping sleeve layer is arranged on the outer wall of the reaction kettle. The reaction kettle is provided with an electronic thermometer used for detecting the reaction temperature in the reaction kettle. A drive motor of the stirring device is a variable frequency motor. The reaction kettle further comprises a programmable logic controller (PLC), wherein the electronic thermometer is in electric connection with an input end of the PLC, and the variable frequency motor is in electric connection with an output end of the PLC. When the reaction temperature rises, the reaction kettle can effectively reduce the reaction speed of a monomer.
Description
Technical field
The utility model relates to water-borne acrylic resin emulsion production equipment technical field, is specially a kind of emulsion synthesis reaction vessel.
Background technology
Compare with traditional solvent based coating, water paint have price low, use safety, saving resource and the energy, advantages such as environmental contamination reduction and public hazards, thereby become the main direction of current development coatings industry.Water soluble acrylic acid olefine resin coating is pollution-free coating with fastest developing speed in water paint, that kind is maximum.Water-borne acrylic resin comprises emulsion acrylic resin, aqueous acrylic resin dispersion (also claiming water-dilutable acrylic acid) and the acrylic resin aqueous solution.Emulsion mainly is emulsified in water under the water-based free radical initator causes synthetic by the oiliness vinyl monomer, resin water dispersion is by free radical solution polymerization or progressively the different technique such as polymerisation in solution is synthetic.From particle diameter: emulsion particle diameter〉the resin water dispersion particle diameter〉aqueous solution particle diameter.See with the above two the most important from application.
Acrylic emulsion is mainly used in the base-material of emulsion paint, occupies important application at Building-coating market, and it is used also in continuous expansion at present; The exploitation of aqueous acrylic resin dispersion in recent years, application cause people's attention day by day, constantly expand in the application of industrial coating, civilian paint field.Usually be divided into pure-acrylic emulsion, acrylate and vinyl acetate emulsion, Silicone acrylic emulsion, uncle's vinegar milk liquid, uncle's acrylic emulsion etc. according to monomer composition.
The polymerisation of aqueous acrylic emulsion polymerization is exothermic reaction, meeting very exothermic in course of reaction, and temperature raises rapidly, and partial monosomy quick response autohemagglutination forms autopolymer, causes the reactor product quality unstable, and performance is low.The synthesis reaction vessel outer wall of existing aqueous acrylic emulsion is provided with the temperature control medium chuck, during the reaction beginning, pass into the steam intensification in chuck, when reaction temperature raises, pass into the cool brine cooling in chuck, not only the reactor temperature change is slower, is unfavorable for the carrying out that reacts, and very high to the requirement of chuck material, production cost is improved.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of emulsion synthesis reaction vessel, the problem that exists to solve prior art.
For solving the problems of the technologies described above, the utility model provides following technical scheme:
The emulsion synthesis reaction vessel, described reactor inside is provided with agitating device, the top is provided with material inlet, the bottom is provided with discharging opening, and outer wall is provided with temperature control medium chuck layer, and described emulsion synthesis reaction vessel is provided with the electronic thermometer for detection of described reactor interior reaction temperature, the drive motors of described agitating device is variable-frequency motor, described emulsion synthesis reaction vessel also comprises PLC, and described electronic thermometer is electrically connected to the input of PLC, and described variable-frequency motor is electrically connected to the output of PLC.
Preferably, described reactor top is provided with gas interface and condensation reflux unit.
Preferably, described reactor is communicated with air compressor and vacuum-pumping equipment by described gas interface simultaneously.
Preferably, described electronic thermometer is arranged on the bottom of described reactor.
after having adopted technique scheme, the beneficial effects of the utility model are: because described emulsion synthesis reaction vessel is provided with electronic thermometer for detection of described reactor interior reaction temperature, the drive unit of described agitating device is variable-frequency motor, described emulsion synthesis reaction vessel also comprises PLC, described electronic thermometer is electrically connected to the input of PLC, described variable-frequency motor is electrically connected to the output of PLC, therefore, after reactor temperature raises, PLC is by reducing the rotating speed of variable-frequency motor, agitator shaft speed is reduced, to reduce monomer reaction speed, thereby reach the purpose of improving the quality of products.
