Abstract

The invention belongs to the technical field of high polymer materials and relates to a polypropylene fiber and a preparation method of the polypropylene fiber. The material comprises the following components in parts by weight: 100 parts of polypropylene, 12-28 parts of ammonium polyphosphate, 2-12 parts of polyol compound, 1-10 parts of organic silicone resin, 1-5 parts of maleic anhydride grafted polypropylene and 0.5-2 parts of an antioxidant. The polypropylene fiber prepared by the invention adopts an expansion type composite synergistic halogen-free and flame-retardant system so as to become a halogen-free, low-smoke, low-toxicity and environment-friendly flame-retardant system and realize a good flame-retardant effect. Compared with the existing expansion type flame-retardant system, the polypropylene fiber disclosed by the invention adopts the ammonium polyphosphate as a main composition part, and the ammonium polyphosphate can be simultaneously used as an acid source and a gas source in an expansion type flame retardant, so that the independent gas source is removed, the reaction of the acidic or the alkaline gas source during the processing process can be avoided, the flame-retardant effect can be prevented from being lowered, and the processing technology is further simplified.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a polypropylene fiber and a preparation method thereof. Background technique [0002] Due to its high tensile strength and low cost, the development speed of polypropylene (PP) fiber has also increased continuously in recent years. Its products are widely used in clothing, decoration, floor covering, health medicine, automobile industry, various home textiles And so on, and its application field has been expanded to national defense military industry and some industrial fabrics. However, PP fiber is flammable and accompanied by burning droplet phenomenon, which limits its wide application field. [0003] The traditional method of making flame-retardant PP fibers is to add halogenated flame retardants. Chinese patent CN 101476171B discloses a method for producing flame-retardant polypropylene fibers, in which decabromodiphenylethane and antimony trioxide are intermixed t...
