Description
Technical field
The utility model relates to a kind of dispersal device, especially a kind of device for the aqueous polyurethane dispersion treatment.
Background technology
While producing waterborne polyurethane resin, dispersion step is comparatively crucial, prior art is generally first base polyurethane prepolymer for use as synthetic in synthesis reactor to be dissolved among interior ketone, to reduce the viscosity of system, under high-speed stirred, add large water gaging again, produce reversing mutually, thereby water becomes continuous phase and forms the aqueous dispersion of polyether polyols with reduced unsaturation, and distillation is finally removed acetone and obtained not solvent-laden waterborne polyurethane resin.
This dispersion process often adopts and relies on strong stirring once to complete in reactor or Scattered Kettle at present; But this kind method has following several shortcoming: the first, because the restriction of rotating speed of agitator and power of motor, the performed polymer viscosity can not be too high, therefore needs to use a large amount of acetone solutions and dilution performed polymer, and whole process loss acetone is more; The second, dispersion process needs high-power power set to ensure that paddle runs up, and the reactor mixing plant is had relatively high expectations; The 3rd, easily produce and stir dead angle in dispersion process, cause and disperse inhomogeneous or the caking gel.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and reduces costs, finely dispersed device for the aqueous polyurethane dispersion treatment.
In order to achieve the above object, the device that is used for the aqueous polyurethane dispersion treatment that the utility model is designed, it comprises dispersion tank, motor, emulsifying head, automatically controlled atmospheric valve, discharging electrically-controlled valve; Described dispersion tank is the tank body of a sealing; Be connected with turning cylinder on emulsifying head, and turning cylinder is connected with motor, thereby drive emulsifying head, stirs, emulsifying head is arranged on dispersion tank inside; The top of dispersion tank is connected with feed pipe, and the bottom of dispersion tank is connected with discharge nozzle, and discharge nozzle is provided with discharging control valve; The dispersion tank top also is provided with discharge duct, and this pipeline is provided with automatically controlled atmospheric valve, is convenient to the Bas Discharged in dispersion tank.
Convenient, reasonable in order to make dispersion tank add water, the top of dispersion tank can also be connected with water inlet pipe, and water inlet pipe is provided with the water supply electrically-controlled valve.
The feed pipe of above dispersion tank is connected with the performed polymer synthesis reaction vessel, and the feed pipe of dispersion tank is provided with electrically-controlled valve; Discharge nozzle on dispersion tank is connected with the desolvation still.
After the power cut-off of performed polymer synthesis reaction vessel, electrically-controlled valve is opened, the performed polymer of metering is inhaled in this device, and the water supply electrically-controlled valve is opened the water that enters metering, and emulsifying head starts to stir under the drive of motor; After disperseing to finish, at first open automatically controlled atmospheric valve, after making the inside and outside atmospheric pressure balance of dispersion tank, form path between this device and desolvation still, open again the discharging electrically-controlled valve of dispersion tank bottom, the material in dispersion tank is inhaled into rapidly in the desolvation still from discharge nozzle; Finally, automatically controlled atmospheric valve and discharging electrically-controlled valve are closed, form negative pressure in dispersion tank, start next dispersion treatment.
After carrying out dispersion step in this device and still before, the dispersion effect contrast of gained is as follows:
The device that is used for the aqueous polyurethane dispersion treatment of the utility model gained, have the characteristics such as simple in structure, easy to use and reasonable in design.
