Description

A solid catalyst for polypropylene polymerization and a method for low Volatile organic compound using the same

The present invention relates to a solid catalyst for polymerization of propylene for VOC reduction and a method for producing polypropylene using the same, and more particularly, a solid catalyst comprising a carrier obtained by reacting dialkoxy magnesium and a metal halide, titanium halide, and an organic electron donor And it relates to a method for producing polypropylene using the same.

Polypropylene is a very valuable material industrially and commercially, and is used in various ways, especially from daily necessities to automobiles and electronic products. When producing these products, polypropylene polymer powder is melted and used. In particular, high melt flow properties of polypropylene are required when manufacturing large products. This melt flowability is directly affected by the molecular weight of polypropylene, and the melt flowability can be improved by reducing the molecular weight by increasing the amount of hydrogen injected during the polymerization of propylene. It is essential.

On the other hand, in Korean Patent No. 10-1540513, a method of producing polypropylene by reacting with a silane-based compound as a catalyst containing a diether internal electron donor was introduced, but there was a need for improvement in activity and stereoregularity. In order to improve the physical properties of the polymer by lowering the cost through increased activity and improving the catalytic performance such as stereoregularity, the use of a diester of an aromatic dicarboxylic acid as an internal electron donor is a widely known method. Related patents have been filed. U.S. Patent No. 4,562,173, U.S. Patent No. 4,981,930, and Korean Patent No.0072844 can be called examples, and the above patents use aromatic dialkyl diester or aromatic monoalkyl monoester with high activity and high stereoregularity. It introduces a method for producing a catalyst that expresses.

The method of the above patents is not sufficiently satisfactory to obtain a highly stereoregular polymer in high yield and improvement is required.

Korean Patent No. 0491387 discloses a non-aromatic dieter material, and Korean Patent No. 0572616 discloses a method for preparing a catalyst using a non-aromatic material having both ketone and ether functional groups as an internal electron donor. However, both of these methods have room to be greatly improved both in terms of activity and stereoregularity.

Volatile organic compounds (VOC) are oligomers of low molecular weight that are created during polypropylene polymerization and remain in the polypropylene resin. They are also used as interior materials for automobiles, but when exposed to high temperature environments, fogging occurs. And a problem causing harm to the human body, and as accidents and damages occur due to this, there is an increasing demand for eco-friendly polypropylene with a lower VOC content.

Accordingly, the present invention relates to a solid catalyst comprising an organic electron donor in which a titanium halide and two types of internal electron donors are combined in a carrier produced by reacting dialkoxy magnesium and a metal halide, and improves the hydrogen reactivity of the catalyst. , To provide a solid catalyst for propylene polymerization capable of producing eco-friendly polypropylene with a lower content of volatile organic compounds (T-VOC) using the above catalyst, and a method for producing polypropylene using the same. .

Therefore, the problem to be solved by the present invention is devised to solve the problems of the prior art, and the present invention is high through a solid catalyst including an organic electron donor combining an internal electron donor including two types of internal electron donors. To provide a catalyst capable of controlling hydrogen reactivity and molecular weight distribution, a solid catalyst for propylene polymerization that effectively improves VOC reduction using the same, and a method for producing polypropylene using the same.

The present invention, in order to solve the above-described technical problem, propylene polymerization, characterized in that it comprises a carrier produced by reacting diethoxy magnesium and a metal halide, a titanium halide, and an organic electron donor consisting of a combination of two types of organic compounds. It provides a solid catalyst for use.

The method for producing a solid catalyst for propylene polymerization of the present invention is characterized in that it comprises the following steps.

(1) reacting diethoxymagnesium with a metal halide compound at a relatively low temperature in the presence of an organic solvent;

(2) reacting two types of internal electron donors while raising the temperature after the diethoxymagnesium reaction;

(3) reacting at a high temperature for a certain period of time;

(4) Secondly reacting with a metal halide compound at a high temperature and washing it.

In the manufacturing process of the solid catalyst specified above, diethoxy magnesium may be particularly preferably used as the dialkoxy magnesium, and accordingly, the diethoxy magnesium used in the step (1) is anhydrous alcohol in the presence of magnesium chloride. As spherical particles with an average particle diameter of 10 to 200 μm obtained by reaction with and a smooth surface, the spherical particle shape is preferably maintained even during polymerization of propylene. If the average particle diameter is less than 10 μm, the prepared catalyst It is not preferable due to the increase of fine particles, and when it exceeds 200 µm, the side bore density decreases and it is difficult to have a uniform particle shape during the manufacture of the catalyst, which is not preferable.

The organic solvent used in the step (1) is not particularly limited in its type, and aliphatic hydrocarbons having 6 to 12 carbons, aromatic hydrocarbons, halogenated hydrocarbons, etc. may be used, more preferably saturated aliphatic having 7 to 10 carbon atoms. Hydrocarbons, aromatic hydrocarbons, and halogenated hydrocarbons may be used, and specific examples thereof may be used by mixing at least one selected from heptane, octane, nonane, decane, toluene, xylene, chlorohexane, chloroheptane, and the like.

In addition, the ratio of the organic solvent to the diethoxy magnesium is diethoxy magnesium weight: 1:5 to 1:50 by volume of the organic solvent, more preferably 1:7 to 1:20, the use ratio is 1:5 If it is less than 1, the viscosity of the slurry increases rapidly and uniform agitation is difficult. If it exceeds 1:50, the apparent density of the resulting carrier decreases rapidly or the surface of the particles becomes rough, which is not preferable.

The titanium halide used in the manufacturing process of the solid catalyst can be represented by the following formula (i):

Ti(OR) _n X _(4-n) ... … … (i)

The second internal electron donor is not particularly limited, and therefore, any compound that can be used as an internal electron donor in the preparation of a Ziegler-based catalyst for olefin polymerization, such as alcohols, ethers, ketones, carboxylic acids, etc., can be used without limitation. Among them, it is preferable to use a 1,3-diether-based compound, and more preferably, one or more selected from 1,3-diether-based compounds are mixed and used as a second internal electron donor. As a specific example, a compound having a diether structure represented by the following formula (ii) is used.
