Description
Technical field
The present invention relates to a kind of coating reaction device, and in particular to coating efficient and environment-friendly type isothermal reaction kettle.
Background technology
Water paint is exactly using coating of the water as diluent, without organic solvent, without benzene,toluene,xylene, formaldehyde, trip
From TDI toxic heavy metals, nontoxic non-stimulated smell is harmless, free from environmental pollution, and paint film is plentiful, sparkling and crystal-clear bright, pliability
It is good and with water-fast, wear-resisting, ageing-resistant, color inhibition, fast drying, it is easy to use the features such as.
Water paint is using water as main solvent, and during the course of the reaction, solvent easily evaporates, and the temperature of reaction increases too fast
Or reaction temperature is too high to promote the evaporation of solvent, solvent evaporation is excessive, and the viscosity of coating can increase, the easy gel of coating,
Coating property difference after gel can not even be used.
The content of the invention
The technical problems to be solved by the invention are that the solvent of coating largely evaporates under higher reaction temperatures, it is therefore intended that
Coating efficient and environment-friendly type isothermal reaction kettle is provided, the problem of solving paint solvent evaporation and influence coating quality.
The present invention is achieved through the following technical solutions：
Heater is installed in coating efficient and environment-friendly type isothermal reaction kettle, including jacket type kettle, the chuck of kettle, institute
Kettle inner vertical is stated inserted with stirring rod, be upward through kettle at the top of the stirring rod is connected with motor, stirring rod it is interior
Portion, which offers level connection joint on passage, the sealed bottom of stirring rod, the side wall of stirring rod, at least two sparge pipes, all water sprays
The water inlet of pipe is connected with passage, and the delivery port of all sparge pipes is mounted on the amount of being provided with above atomizer, kettle
Cylinder, the lower section of the graduated cylinder is provided with opening, and opening lower section is connected by the interior forcing pipe provided with force (forcing) pump with passage.The stirring
The sparge pipe being located on rod on the wall of the same side is parallel to each other each along the axial direction of stirring rod.
Kettle is main reaction vessel in the present invention, using the kettle of jacket type as reaction vessel than traditional glass
Container temperature control ability is good, and chuck has certain thermal insulation performance, it is to avoid reaction vessel is brought rapidly up, and make it that reaction solution continues
Reacted under high temperature, rapid solvent evaporation and the viscosity for influenceing coating；Stirring rod make it that reaction solution is well mixed, and reaction is complete, electricity
Machine rotates control stirring rod and rotated, the phenomenon such as stirring rod avoids occurring in reaction solution reuniting；The present invention will need the moisture of addition
Batch is added into reactor, and fresh water is added during the course of the reaction has certain cooling effect, and the water being initially added will be anti-
The raw material in kettle is answered just to dissolve and be well mixed, during temperature increment, the content of moisture is also incremented by, but temperature increases
Speed is slow, and moisture evaporation is relatively slow, slower than traditional disposable substantial amounts of water additional issue speed of addition, disposably adds substantial amounts of
Water, after temperature is increased rapidly, reaction temperature is difficult to lower, and causes solvent volatilization too fast；And batch adds water, pass through reactor
Actual reflection situation determines the amount added water in body so that temperature is raised slowly to suitable reaction temperature, in suitable reaction
At a temperature of constant temperature；Graduated cylinder is used to measure the amount once added water；The mode that adds water of the present invention is different from traditional mode that adds water, this hair
It is bright to be added water by stirring rod, water is sprayed during stirring rod spinning, the moisture decentralization that atomizer sprays is big, because
This, the present invention can send water forth in each position of reaction solution, carry out uniform decrease in temperature and ensure that water can be quickly blended in instead
Answering reduces the viscosity of reaction solution in liquid；The present invention realization principle be：The heater preheating reactor in chuck is opened, in amount

Begin slowly to rotate, the part water in graduated cylinder is pumped into kettle by force (forcing) pump so that the raw material in kettle just dissolves, closed
Force (forcing) pump is closed, stops adding water；Continue to stir and continue to heat, it was observed that when reaction solution starts to become sticky, opening in force (forcing) pump, graduated cylinder
Water controls amount of water by the change of observing response temperature, kept away by being sprayed after pressurized water tubes through passage from atomizer
Exempt from the situation for unexpected high temperature occur, side border ring adds water controlling reaction temperature but do not interfere with reaction, reaches optimum anti-
Answer after temperature, be incubated, control the heating dynamics of heater；Keeping temperature does not have greatly changed, it is to avoid solvent evaporated
Fast and no solvent make-up.The present invention selects jacket reactor as reaction vessel, and changes the part of jacket reactor
Structure, can realize the stirring of change border ring and mass simultaneous adds water, and stir, react, add water can be while carry out, when having saved reaction
Between, reaction rate is improved, the situation for a large amount of solvents volatilization that unexpected high temperature is caused is solved.
Covered with asbestos gauge on the side inwall of the kettle chuck, the asbestos gauge is located at chuck close to kettle reaction chamber
Side inwall and heater between.Heat on heater action-reaction liquid is scatter by the present invention using asbestos gauge,
Thermally equivalent, it is to avoid localized hyperthermia.
The inside of the kettle is also equipped with two cooling cylinders that condensed water is housed, and described two cooling cylinders are respectively positioned on kettle
Top, two cooling cylinders are located at the both sides of stirring rod respectively.Cooling cylinder has certain cooling effect, and the condensation of cooling cylinder can
High temperature is avoided out, solvent is flashed to after vapor, vapor runs into upwards can be condensed into water after cooling cylinder, water can return to reaction again
In container, recycling design, reduction reaction fluid viscosity.
Loading hopper is connected with the side wall of the kettle, the loading hopper is connected by feed pipe and kettle reaction chamber
Logical, feed pipe is close to autoclave body bottom, and feed pipe is towards kettle reaction chamber bottom angled.Raw material in loading hopper is along charge pipe
To autoclave body bottom is snapped down to, fed since bottom, it is to avoid stock dispersion produces a large amount of dust injury operating personnel in atmosphere
It is healthy.
The present invention compared with prior art, has the following advantages and advantages：
1st, coating efficient and environment-friendly type isothermal reaction kettle of the present invention selects jacket reactor as reaction vessel, and changes folder
The part-structure of reactor is covered, the stirring of change border ring can be realized and mass simultaneous adds water, stir, react, add water can be while enter
OK, the situation for a large amount of solvents volatilization that unexpected high temperature is caused is solved；
2nd, the present invention realizes that precipitation batch is added during the course of the reaction for the reaction dress of aqueous double-component coating, temperature control energy
Power is good, can be good at adjusting its viscosity, has saved the reaction time, improved reaction rate,；
3rd, coating efficient and environment-friendly type isothermal reaction kettle of the present invention passes through cooling cylinder recycling design, it is to avoid solvent loss and cause
Coating gel.
