Abstract
The utility model discloses a kind of base polyurethane prepolymer for use as emulsifying systems, described system comprises a technique water pump and an oligomer pump, technique water pump is all connected with the liquid feeding end of static mixer with the outlet end of oligomer pump, hybrid chamber is provided with in static mixer, the outlet end of this static mixer is connected with the liquid feeding end of emulsifying kettle, the dehvery lift of this oligomer pump is 0.2Mpa-0.4Mpa, and the dehvery lift of technique water pump is 0.2Mpa-0.4Mpa.System adopts Liquid-liquid mixing device continuous emulsification, utilizes the high efficiency dispersion function of static mixer to carry out the emulsification of oligomer.Effectively improve the stability of product quality, guarantee that follow-up emulsifying kettle equipment operates steadily, stop potential safety hazard, greatly reduce the power of emulsifying kettle motor simultaneously.
Description
Technical field
The utility model relates to the technical field of polyaminoester emulsion production system, specifically base polyurethane prepolymer for use as emulsifying systems, particularly its system syndeton.
Background technology
Produce polyaminoester emulsion, first will produce the oligomer of polyurethane.Then, with about 10 DEG C oligomer weight 2-3 fresh water (FW) is doubly quick at short notice, oligomer dispersion is become polyaminoester emulsion.The quality of the influential effect emulsion of dispersion and decision emulsion intercalation method.
Before, be that oligomer is put into emulsifying kettle, then add the fresh water (FW) of 10 DEG C fast.Under the rapid stirring of 240rpm, become emulsion simultaneously.Because oligomer viscosities large (4000-6000cps) stirs resistance greatly, require that the power of stirring motor is far beyond the power of agitator of popular response still.Emulsion as single still 1.2 tons needs the motor of 22KW, and the resistance difference be subject to due to the large paddle of viscosity differences of oligomer and fresh water (FW) is large, instability causes emulsifying kettle shake very seriously, brings equipment and potential safety hazard.
Summary of the invention
The purpose of this utility model is to provide base polyurethane prepolymer for use as emulsifying systems, adopt Liquid-liquid mixing device continuous emulsification, the high efficiency dispersion function of static mixer is utilized to carry out the emulsification of oligomer, oligomer viscosities after continuous emulsification reduces greatly, and the uniformity of emulsion also effectively promotes, require that the power of agitator of reactor reduces greatly, middle vibrations are excessive in working order to avoid emulsifying kettle.
To achieve these goals, the technical solution of the utility model is: base polyurethane prepolymer for use as emulsifying systems, it is characterized in that: described system comprises a technique water pump and an oligomer pump, technique water pump is all connected with the liquid feeding end of static mixer with the outlet end of oligomer pump, hybrid chamber is provided with in static mixer, the outlet end of this static mixer is connected with the liquid feeding end of emulsifying kettle, and the dehvery lift of this oligomer pump is 0.2Mpa-0.4Mpa, and the dehvery lift of technique water pump is 0.2Mpa-0.4Mpa.
The utility model discloses base polyurethane prepolymer for use as emulsifying systems, system adopts Liquid-liquid mixing device continuous emulsification, utilizes the high efficiency dispersion function of static mixer to carry out the emulsification of oligomer.Effectively improve the stability of product quality, guarantee that follow-up emulsifying kettle equipment operates steadily, stop potential safety hazard, greatly reduce the power of emulsifying kettle motor simultaneously.Overall system design is reasonable, is skillfully constructed, has good practicality, be easy to apply.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
The utility model discloses base polyurethane prepolymer for use as emulsifying systems, it is different from prior art and is: described system comprises technique water pump 1 and an oligomer pump 2, technique water pump 1 is all connected with the liquid feeding end of static mixer 3 with the outlet end of oligomer pump 2, hybrid chamber is provided with in static mixer 3, laterally at least one helical form agitating roller is provided with in hybrid chamber, the surface distributed of this agitating roller has spiral lamination, be convenient to promote mixed effect, and the stability of control appliance is convenient in the slow-speed of revolution, the outlet end of this static mixer 3 is connected with the liquid feeding end of emulsifying kettle 4, the dehvery lift of this oligomer pump 2 is 0.2Mpa-0.4Mpa, the dehvery lift of technique water pump 1 is 0.2Mpa-0.4Mpa, this dehvery lift can guarantee oligomer and fresh water (FW) high efficiency dispersion continuous emulsification in the hybrid chamber of static mixer.
In the specific implementation, the technological principle of native system is: oligomer pump (0.3Mpa)+technique water pump (0.3Mpa)+emulsifying kettle, and wherein, the power of oligomer pump is 1.1KW, the power 2.2KW of technique water pump, the power of agitator 3KW of emulsifying kettle.
The above is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, although the utility model discloses as above with preferred embodiment, but and be not used to limit that this is novel, have in any art and usually know the knowledgeable, not departing from the scope of technical solutions of the utility model, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be the content not departing from technical solutions of the utility model, according to any simple modification that technical spirit of the present utility model is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
