preparation example Construction

[0029] The present invention also provides a preparation method of the above-mentioned polypropylene resin: adopting the Spherizone polypropylene gas-phase polymerization process, using the Ziegler-Natta catalyst system as a catalyst, and adding an external electron donor for preparation;

[0030] Wherein, the consumption of catalyst is 0.01-0.05kg / 1000kg C 3 h 6 , in one embodiment is 0.0313kg / 1000kg C 3 h 6 , the external electron donor is Donor-C (cyclohexylmethyldimethoxysilane), and the amount of external electron donor is 2-8kg / 1000kg C 3 h 6 , in one embodiment is 5kg / 1000kg C 3 h 6 .

[0031]The Spherizone process is the latest generation of polypropylene production process technology developed by Basell based on the Spheripol process. The process has two sections, two reaction areas with completely different hydrodynamic behavior: a fluidized section is called the lifting section, and the polymer is rapidly fluidized or dilute-phase transported upwards; a compa...

Abstract

The invention discloses a polypropylene fiber resin and a preparation method thereof. The polypropylene fiber resin comprises a polypropylene resin, a peroxide and an antioxidant, wherein the mass ratio of the polypropylene resin to the peroxide is 100: 0.06-0.10, and the mass ratio of the polypropylene resin to the antioxidant is 100: 0.1-0.25; and the polypropylene resin comprises five inner racemization structures and one outer racemization structure which are adjacent to each other, and the proportion of the five inner racemization structures and the outer racemization structure which are adjacent to each other in the polypropylene resin is greater than or equal to 96.5%. The polypropylene fiber resin disclosed by the invention has relatively high crystallinity and flexural modulus.

Description

technical field [0001] The invention relates to a polypropylene fiber resin, which belongs to the field of polymer materials. Background technique [0002] Polypropylene (PP) fiber is one of the four major synthetic fibers with great potential for development. It is a fiber product made of polypropylene by melt spinning. Because polypropylene fiber is light, non-toxic, and dirt-resistant , hydrophobic, wear-resistant, heat insulation and other advantages, are widely used in packaging, cigarette filter materials, carpets, non-woven fabrics, clothing and other products, is the fastest growing variety of synthetic fibers in recent years, has become second only to Polyester is the second largest synthetic fiber product. [0003] With the development of differentiation and functionalization of polypropylene fibers, higher requirements are placed on the performance of fiber-grade polypropylene special resins, which must have high melt flow rate, high crystallization, high elongat...
