Abstract

The invention relates to the field of polypropylene fibers, and particularly discloses cold-resistant polypropylene and a preparation method thereof. The cold-resistant polypropylene is prepared fromthe following raw materials in parts by weight: 50-70 parts of polypropylene, 5-15 parts of a styrene-butadiene-styrene block copolymer, 5-15 parts of a compatilizer and 5-16 parts of a plasticizer. The cold-resistant polypropylene disclosed by the invention can be used in a low-temperature environment and has the advantage of prolonging the service life of polypropylene at a low temperature.

Description

technical field [0001] The application relates to the field of polypropylene fibers, more specifically, it relates to a cold-resistant polypropylene and a preparation method thereof. Background technique [0002] Polypropylene fiber, also known as polypropylene fiber, is a more practical synthetic fiber at present. It is mainly spun from isotactic polypropylene obtained by propylene polymerization, and polypropylene fiber has high strength, good toughness, and chemical resistance. And the advantages of good antimicrobial and low price, so it is widely used in ropes, fishing nets, safety belts, luggage belts, safety nets, sewing threads, cable foreskins, geotextiles, filter cloths, felts for papermaking and paper reinforcement materials and other industries field. [0003] The Chinese invention patent with the application number CN103590129B discloses a kind of dyed polypropylene fiber, and its raw materials include by weight percentage: polypropylene 80-95%, sodium propylen...
