At present, it is typically also by high-speed stirred, spray cooling or the method preparation such as high-gravity rotating bed as mentioned above containing the adduct of magnesium halides of other electron donors except alcohol and water in addition to.
The introducing of electron donor in adduct of magnesium halides can improve the olefinic polymerization performance of catalyst, and different adduct preparation methoies also has to a certain extent the olefinic polymerization performance for improving the thus catalyst that adduct is further prepared.As EP395083 prepares the magnesium chloride adduct of low ethanol content using the method that the higher adduct of alcohol content is carried out successively partial dealcoholation, the catalyst further prepared by the adduct has good morphological stability, have in olefin polymerization and avoid or limits molecule being formed, the advantage for bringing problem is run to polymerization equipment to reduce.
It is known that, catalyst with succinate compound compound as internal electron donor is when for olefinic polymerization, resulting polymers have wide molecular weight distribution, are particularly suitable for the wide molecular weight distribution resin product of monocyclic pipe device production, and the new-product development of monocyclic pipe device has been widened significantly.But the hydrogen response of the catalyst with succinate compound compound as internal electron donor is poor, this limits to a certain extent the application of such catalyst.It is found by the applicant that, the catalyst further prepared by the adduct prepared through the manufacturing process of the construction unit to cooling medium with hole under pressure using the adduct melt containing electron donor, when for olefinic polymerization, catalyst has obtained certain improvement to the sensitivity of hydrogen, and the preparation technology of adduct is simple to operate, adduct particles size is controllable.
The content of the invention
It is an object of the invention to provide a kind of preparation method of the new catalytic component for olefinic polymerization, it is characterized by preparing adduct of magnesium halides by the new method of the construction unit with hole to cooling medium under pressure using by adduct melt, adduct of magnesium halides is then set to contact with titanium compound and succinate compound compound;And the catalytic component by the method preparation and catalyst system and its application.When the caltalyst formed by catalytic component prepared according to the methods of the invention ties up to the catalyst as olefinic polymerization, the hydrogen response of further improvement is shown.
As stated in the Background Art, the preparation method of adduct of magnesium halides ball type carrier includes spray drying method, spray cooling, high pressure extrusion methods, high-speed mixing method and high-gravity rotating bed method etc..
(1) spray drying method:With nitrogen by MgCl2-ol mixed system sprays into hothouse by specially designed nozzle, and is dried to spherical magnesium chloride support in the noble gases of preheating;
However, the present inventor has found under study for action, using spray drying method in carrier preparation process, a large amount of ethanol, nitrogen, energy are expended, and the carrier granular form for finally giving is not good;
Adduct carrier prepared by simultaneous spray drying method has following impact on catalyst:Due to the outlet temperature of spray-dried instrument it is higher, cause the ball type carrier alcohol content for obtaining relatively low, especially the alcohol on spherical carrier particle surface is very few, during follow-up load titanium, active component with carrier useful effect and can not be combined on the surface, made active ingredient content in catalyst low and then affected the polymerization activity of final catalyst.
(2) spray cooling:Magnesium chloride alcohol mixed system is sprayed into into hothouse by specially designed nozzle with nitrogen, and condensation forms spherical magnesium chloride support in cooling medium;
However, the process is complex, instrument and equipment requirement is higher, is difficult the ball type carrier that small particle is obtained, and alcohol content is too high in the carrier for preparing;
The adduct carrier that simultaneously prepared by spray cooling has following impact on catalyst:In ball type carrier, because mean diameter is larger, and alcohol content is higher, when adduct and titanium-containing compound react, because reaction is excessively fierce, often crushes carrier, and causing the fine powder content of final polymer increases.
(3) high pressure extrusion cooling method:With the less oil refining of viscosity, paraffin, white oil etc. as reaction medium, temperature of reaction system rise to 120-130 DEG C and maintain a period of time after, be filled with high pure nitrogen into reactor, make reacting kettle inner pressure reach 10-15 atmospheric pressure;Afterwards, the mixture of chlorination magnesium alcoholate melt and reaction medium is discharged in cooling medium by a discharge duct;The length of discharge duct is 3-10m, and bore is 1-2mm, and flow rate of the mixed liquor in pipe is about 4-7m/s;
The technique has as a drawback that:The form of higher to equipment requirements and resulting chlorination magnesium alcoholate granule is not good enough, so that the final catalyst granules form for preparing is not good enough, the particle shape of polymer is not ideal enough, and the bulk density of polymer is not high.
(4) high-speed mixing method:Anhydrous magnesium chloride and alcohol are added to by a certain percentage in the inert liquid medium immiscible with it, are heated under agitation, make EtOH/MgCl2Form adduct melt and disperse in media as well, emulsifying then to be carried out in high speed agitator, and be transferred in the medium of low temperature, by MgCl2-ol adduct rapid condensation cured globulate MgCl wherein2Carrier;
The technique has as a drawback that:The adduct carrier fractions wider distribution for obtaining, and be difficult to prepare small carrier, the activity of the catalyst for further preparing is also unsatisfactory.
(5) higee technology:Anhydrous magnesium chloride and alcohol are added to by a certain percentage in the inert liquid medium immiscible with it, are heated under agitation, make EtOH/MgCl2Form adduct melt and disperse in media as well, it is then transferred to high-gravity rotating bed, static distribution device through being arranged at rotor center is equably sprayed on the inner edge of the filler that adjustment is rotating, material is adjusted after filler shearing, the dispersion for rotating, and magnesium chloride/alcohol adducts melt is scattered in inert media in the form of fine drop;
The shortcoming of the technique:It is high-gravity rotating bed produce it is less (<30 microns) particle diameter and greater particle size (>65 microns) carrier when, diameter of carrier wider distribution;During steady production, generally using blending agent (generally white oil and silicone oil mix) could normally produce, but with the continuous consumption of production process, need to be continuously replenished fresh inert media, keep the ratio of the two, so for the repetition stability for maintaining carrier production, difficulty is increased.
