Abstract

The invention relates to the field of olefin polymerization catalysts, and discloses a carrier of a catalyst with a function of catalyzing olefin polymerization, a preparation method and application of the carrier, the olefin polymerization catalyst and application of the olefin polymerization catalyst. The catalyst carrier is high in strength, and the olefin polymerization catalyst prepared from the catalyst carrier is high in strength.

Description

technical field [0001] The invention relates to the field of olefin polymerization catalysts, in particular to a catalyst carrier for olefin polymerization, a preparation method and application thereof, and an olefin polymerization catalyst and application thereof. Background technique [0002] Currently, ZN catalysts are used as catalysts for olefin polymerization, and most of them use magnesium chloride alcoholates as supports, and the catalysts are obtained by supporting titanium halides to form titanium active centers. Among them, spherical catalysts prepared by spherical carriers are more popular in the market due to their good fluidity. [0003] At present, spherical carriers can be prepared by methods such as spray drying, spray cooling, high-pressure extrusion, high-speed stirring, emulsifier method, and high-gravity rotating bed method, such as WO99 / 44009 and US4399054, etc. disclose that magnesium chloride alcohol can be emulsified by high-speed stirring at high te...
