Abstract

The present invention belongs to the chemical technology field, particularly relates to polypropylene fiber containing a composite nitrogen phosphorus flame retardant used for periwig and its production method. The invention is characterized in that the components comprise by mass: 100 parts of polypropylene, 5 to 20 parts of dehydrating agent, 5 to 20 parts of charring agent, 5 to 20 parts of foaming agent, 1 to 5 parts of coupling agent, 1.5 to 2.5 parts of heat stabilizer and 1.0 to 2.0 parts of polypropylene heat degradation masterbatch. Polypropylene, the heat stabilizer and polypropylene heat degradation masterbatch are added into a high-shear mixer in proportion, the dehydrating agent, the charring agent, the foaming agent and the coupling agent are orderly added for improving the continuously stirring mixing rotating speed, color masterbatch is added and the rotating speed is kept, the material is discharged after continuously stirring, the discharged material is extruded by adouble screw extruder, melt spinning is performed after drying, the extruded nascent fiber is cooled and reeled by crosswind and a filament is obtained after drawing-off. The present invention has the advantages of non-toxicity, smoke suppression, friendly environment and the like.

Description

[technical field] [0001] The invention relates to the field of chemical technology, in particular to a polypropylene fiber for wigs compounded with nitrogen and phosphorus flame retardants and a production method thereof. [Background technique] [0002] At present, people always want to change their hairstyles but are worried that their hair will be damaged. Long-term blow-drying, dyeing, and perm will damage the hair quality. In order to have a fashionable shape at any time, wigs are becoming more and more popular. [0003] Patent 200910235458.4, low-temperature flame-retardant polypropylene fiber for wigs discloses a polypropylene with brominated flame retardants, antimony-based flame retardants and nanomaterials, but many studies have proved that brominated flame retardants are harmful to human health impact, has been banned in the European Union and the United States. Brominated compounds are bioaccumulative and destructive to the human nervous system, immune system and...
