Enrichment method.
Background technique
Ammonium stearate emulsion is the aqueous dispersion of ammonium stearate, it can be scattered in neutral, alkaline aqueous body in any proportion
In system, the surface tension of liquid in water-based system can be effectively reduced, so easily blistering and foam stabilizing, ammonium stearate emulsion are commonly used for
The foam stabiliser of aqueous PA, PU intumescent coating, foam stabilizing effect are very outstanding.
Currently without the detection method specifically for stearic acid residual quantity in ammonium stearate emulsion, it is not easy to technical staff couple
The research of ammonium stearate emulsion.
Summary of the invention
(1) the technical issues of solving
For the deficiency of existing detection technique, the present invention provides remain stearic enrichment in a kind of ammonium stearate emulsion
Method is solved currently without the detection method specifically for stearic acid residual quantity in ammonium stearate emulsion, is not easy to technology people
The problem of member is to the research of ammonium stearate emulsion.
(2) technical solution
In order to achieve the above object, the present invention is achieved by the following technical programs: being remained in a kind of ammonium stearate emulsion
Stearic enrichment method, comprising the following steps:
Step 1: dehydrated alcohol carries out Cold pretreatment；
Step 2: accurately measuring dehydrated alcohol, is placed in a beaker, and accurately weighs 20% ammonium stearate emulsion or 30% tristearin
Sour ammonium lotion is placed in another beaker, and record weight is M1；
Step 3: using Special magnetic blender, while stirring to ammonium stearate emulsion, while being poured into dehydrated alcohol, constantly stirs
Mix extraction；
Step 4: after the completion of stirring is extracted, it is filtered under diminished pressure isolated solid precipitating；After draining completely, solid is washed
Precipitating；After draining completely, then wash solid precipitating；After draining completely, solid precipitating is collected, solid precipitating is packed into self-styled
In bag, it is stored in refrigerator-freezer；
Step 5: freeze-drying process solid precipitating weighs the weight of solid precipitating, is completely dried ensuring that solid precipitates
Under the premise of, as early as possible by solid precipitate collect and be stored in refrigerator-freezer, record solid precipitating weight be M2.
Preferably, the temperature of the step 1 Cold pretreatment is set as -10 DEG C~-40 DEG C.
Preferably, magnetic agitation rotating speed is 800rpm~1000rpm in the step 3.
Preferably, the vacuum degree being filtered under diminished pressure in the step 4 is 0.05-0.10Mpa.
(3) beneficial effect
The present invention provides remain stearic enrichment method in a kind of ammonium stearate emulsion.Have it is following the utility model has the advantages that
Stearic enrichment method is remained in the ammonium stearate emulsion, by Special magnetic blender, while to ammonium stearate
Lotion stirring, while being poured into dehydrated alcohol, is stirred continuously extraction；After the completion of stirring is extracted, it is filtered under diminished pressure isolated solid precipitating；
After draining completely, washing solid precipitating；After draining completely, then wash solid precipitating；After draining completely, it is heavy to collect solid
It forms sediment, solid precipitating is fitted into valve bag；Freeze-drying process solid precipitating, weighs the weight of solid precipitating, is ensuring solid
It precipitates to precipitate under the premise of being completely dried, as early as possible by solid and collects and be stored in refrigerator-freezer, the weight of record solid precipitating reaches
Realize the detection of stearic acid residual quantity in ammonium stearate emulsion, the purpose studied convenient for technical staff ammonium stearate emulsion.
Specific embodiment
In order to be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, tie below
Specific embodiment is closed, the present invention is further explained.
