Description
Technical field
The present invention relates to a kind of catalyst component for olefinic polymerization and preparation method thereof and the catalyzer for olefinic polymerization comprising this catalyst component, and this is used for the application of catalyzer in olefinic polyreaction of olefinic polymerization.
Background technology
As everyone knows, when the Ziegler-Natta catalyst of magnesium chloride alcohol adduct load is polymerized for alkene (particularly propylene), its performance is obviously better than the catalyzer of other carrier institute load.Therefore, mostly prepare by halogenated titanium being carried on magnesium chloride alcohol adduct for the catalyzer of olefinic polymerization at present.In order to obtain ball type carrier, extrude by spraying dry, spray cooling, high pressure, the method preparation such as high-speed stirring, mulser method and high-gravity rotating bed method, spherical alcohol adduct can be formed by quenching after high-speed stirring emulsified magnesium chloride alcohol adduct system under high temperature as WO99/44009 and US4399054 etc. discloses.
But, when the catalyzer prepared by above-mentioned published magnesium chloride alcohol adduct is used for olefinic polymerization, is easy to the Fragmentation Phenomena that polymer particle occurs in the course of the polymerization process, thus causes fine polymer powder more.In order to overcome this shortcoming, people attempt again electron donor compound to be incorporated in advance in the carrier preparation of magnesium chloride alcohol adduct, such as: known for industry internal electron donor phthalate compound is incorporated in the synthesis of magnesium chloride alcohol adduct carrier by CN1169840C and CN1286863C, thus obtain " magnesium dichloride-alcohol-phthalic ester " ball type carrier, then by this carrier and titanium tetrachloride reaction to form catalyzer.But described mixture ball type carrier is easily clamminess in preparation process, be difficult to form the suitable spheroidal particle of size.
CN102040683A discloses a kind of method reacting to prepare carrier by magnesium halide alcohol adduct and oxirane compound, and specifically discloses after magnesium halide alcohol adduct melting dispersion, adds oxirane compound; Or in the reactor directly joining containing oxirane compound after magnesium halide alcohol adduct melting is disperseed.But, adopt the method Kaolinite Preparation of Catalyst carrier to there is preparation process instability, easily carrier adhesion occurs, and the shortcoming that carrier molding effect is bad.
In US4861847, epoxy compounds and tributyl phosphate compounds is used to dissolve magnesium chloride, re-use titanium tetrachloride after forming uniform solution separate out carrier and carry out titanium load, reaction product is very complicated, the by product generated is difficult to process, in the process using titanium tetrachloride to separate out, also can use some precipitation additives, this makes byproduct of reaction more complicated, and carrier pattern is difficult to control.Also have technology to add alcohol in above-mentioned dissolution system, accelerate the adding of alcohol tributyl phosphate and epoxy to its solvency action, but itself can be had an effect with titanium tetrachloride and can have an impact to follow-up catalyzer pattern and performance.These technology are all use titanium tetrachloride to separate out carrier with Kaolinite Preparation of Catalyst, and as previously described, reaction is complicated, and waste liquid cannot reclaim for this process, and after particularly introducing alcohol in dissolution system, its carrier pattern is difficult to control more.
