Curve A be embodiment one when preparing polysulfone resin, there is the viscosity measurements curve in polyreaction, curve B is embodiment three
When preparing polysulfone resin, there is the viscosity measurements curve in polyreaction.
Polysulfones is a kind of thermoplastic resin, and when dissolving in organic solvent, the viscosity of its organic solution promotes with the degree of polymerization
And it is linearly increasing.Therefore can be by its degree of polymerization of viscosity indirect reaction of organic solution.The viscosity of organic solution can be by viscous
Degree meter, the load current value of stirring slurry, stirring paddle converter output torque value directly or indirectly reflect.Use in the detection
Stirring paddle load current value is as the qualitative reference of the degree of polymerization (viscosity).

Embodiment ten: a kind of polysulfone resin industrialized producing technology, comprises the following steps:
A kind of polysulfone resin industrialized producing technology, comprises the following steps:
Step one: polyreaction pre-treatment: use 500L chuck glassed steel reaction vessels is as polymerization reaction kettle, by metering
Tank quantitatively adds the organic solvent N,N-dimethylacetamide of 400L in polymerization reaction kettle;Low rate start anchor formula stirring paddle, turns
Speed is 2r/min;Manual weighing, adds 70kg44 dichloro diphenyl sulfone, 160kg bisphenol-A, 110kg carbonic acid in polymerization reaction kettle
Potassium, then closes batching hole.In still, it is passed through low-pressure nitrogen, continues 5min.In making polymerization reaction kettle, oxygen all displaces.Throw
Material process is complete.Temperature controls to start to enable, temperature control settings point 63 DEG C, range of accommodation 61~64 DEG C;
Step 2: polyreaction: step up the rotating speed of anchor formula stirring paddle to 45r/min, settle out, monitors that polymerization is anti-
Answer the temperature curve value in still, stirring paddle motor inverter torque value and power current flow valuve;200 DEG C of heat conduction it are passed through in interlayer
Oil, slowly promotes polymerization reaction kettle temperature, and temperature promotes unsuitable too fast, it is to avoid burst porcelain;When polyreaction temperature in the kettle rises to
When about 120 DEG C, stirring paddle motor inverter torque value and power current flow valuve in polymerization reaction kettle start gradually to promote, mark
Polyreaction has begun to.Reaction generates polysulfones, potassium chloride, water, CO2, a small amount of N,N-dimethylacetamide is decomposed into CO2With
NH3.Wherein gaseous component CO2、NH3, evaporation N,N-dimethylacetamide, the water of evaporation and protection gas nitrogen pass through polymerization tower
Once enter condenser after condensation.Owing to controlling condenser temperature, temperature control settings point 63 DEG C, range of accommodation 61~64 DEG C,
By after gas-liquid separator separates gas phase after water and N,N-dimethylacetamide condensation, collect chilling flux bath gives over to follow-up
Use;Residue gas phase CO2、NH3It is delivered to output device with nitrogen;
Keeping high-temperature hot oil to continue conveying, polyreaction is slow exothermic polymerization reaction, when temperature rises to 135 DEG C,
Stop sending into high-temperature hot oil;Along with proceeding of reaction, temperature slowly promotes;Optimal reaction temperature is 160 DEG C.When polymerization is anti-
When answering temperature in the kettle more than 160 DEG C, suitably open the switch valve between chilling flux bath and polymerization reaction kettle, make polymerization reaction kettle
Interior temperature maintains 160 ± 1 DEG C;Maintain polyreaction;Because the boiling point of N,N-dimethylacetamide 165 DEG C, below boiling point
Reaction temperature can effectively reduce evaporation, reduces energy consumption;
Step 3: polyreaction terminates: due to the most corresponding different viscosity of the polysulfones of different polymerization degree, its
Real time viscosity value can be with the converter torque value of anchor formula stirring paddle and the indirect nominal of power current flow valuve.Change when anchor formula stirring paddle
Frequently device torque value and power current flow valuve reach desired value, and mark extent of polymerization meets requirement, starts to terminate reaction;
Chloromethanes is delivered to below polymerization reaction kettle liquid level, the converter torque value of anchor formula stirring paddle and power current flow valuve
Trend eases up, and starts constant after 5min, closes the valve between chloromethanes and polymerization reaction kettle;Terminate reaction to complete;Anchor afterwards
The converter torque value of formula stirring paddle and power current flow valuve continue the most in time and change;
Because chloromethanes is colourless flammable toxic gas, belong to organohalogen compounds.It is slightly soluble in water, is soluble in ether, benzene etc..
There is combustibility, explosive mixture, explosion limit 8.1%~17.2% (volume) can be formed with air;Chloromethanes 60 DEG C with
Methanol is generated during upper hydrolysis.After terminating reaction, chloromethanes is that excess is added, and the chloromethanes of excess is in the environment of 160 DEG C
Evaporation, meets water, hydrolysis in the condenser E101 of 63 DEG C, generates hydrochloric acid and methanol, and methanol discharge vaporization to glass regards in bucket, molten
Yu Shui;Remaining liq (comprising trace hydrochloric acid) is collected in chilling flux bath;Stop being passed through nitrogen, open chilling flux bath with poly-
Closing the valve between reactor, enter in polymerization reaction kettle by cooling solvent discharge, the hydrochloric acid in polymerization reaction kettle is with excess carbonic acid
Nak response, generates potassium chloride and CO2;
Step 4: polyreaction post processing: cooling polymerization reaction kettle, to 63 DEG C, in cycle time switch drainage line
Valve (5s opens, and 10s closes), to polymerization reaction kettle, material is all released in pure water (58 DEG C), is dissolved in N, N-dimethyl second
Polysulfone resin in amide starts to separate out fluffy solid resin;Dissolving chloromethanes in a solvent is continued in water if had simultaneously
Being hydrolyzed into methanol and hydrochloric acid, hydrochloric acid generates potassium chloride and CO with potassium carbonate reaction2;63 DEG C of temperature of gas phase and liquid phase section set,
The chloromethanes that can make micro-excess is fully hydrolyzed, and reduces danger;
Step 5: purify: the polysulfone resin using water-boiling method to separate out step 4 carries out purification processes.
Step 6: extrusion: in 174 DEG C by hot-extrudable for polysulfone resin bar.
Whole reaction produces about 120kg polysulfone resin.According to the difference of the degree of polymerization, the different trades mark, quality can be distinguished
Constant.When 174 degrees Celsius of hot-extrudable bars of polysulfone resin, the visual clarity of the polysulfones bar adding capping reagent is more preferable,
Analyze reason, add polysulfone resin prepared by capping reagent, cross dimeric molecule less, be suitable for injection and hot melting temperature is stable;Do not add
Adding the polysulfones of capping reagent under same extrusion temperature, the visual clarity of polysulfones bar is not so good as the former, suitably squeezes when promoting
After going out temperature, transparency improves, and analyzes reason, and part high polymer does not melt, and affects transparency during extrusion, and high polymer was
Dimeric molecule.
