Problems solved by technology

When the human body touches polypropylene with static electricity, it will feel electric shock, and static electricity can also cause malfunctions of electronic equipment. What is more serious is that static electricity accumulation will cause electrostatic attraction (or repulsion), electric shock or spark discharge. This will lead to huge disasters under the environmental conditions of flammable and explosive substances

[0194] Preparation of Polypropylene Base Resin HPP

[0195] 1. Preparation of polypropylene base resin HPP101

[0196] 1) Raw material

[0197] Preparation of the main catalyst: Fully replace the 16L pressure-resistant reactor with a stirrer with nitrogen, then add 10L ethanol, 300mL 2-ethylhexanol, 11.2g iodine, 8g magnesium chloride and 640g magnesium powder into the reactor and stir to mix Evenly, while stirring, the system was heated to 75°C and refluxed until no more hydrogen gas was released. Stop the reaction, wash with 3L of ethanol, filter and dry to obtain dialkoxymagnesium carrier. Its D50 is 30.2 μm, its SPAN is 0.81, and its m value is 0.015. Take 650 g of the above-mentioned dialkoxymagnesium carrier, 3250 mL of toluene and 65 mL of di-n-butyl phthalate (DNBP) to prepare a suspension. In a 16L pressure-resistant reactor that has been repeatedly replaced by high-purity nitrogen, add 2600 mL of toluene and 3900 mL of titanium tetrachloride, raise the temperatur...

Abstract

The invention provides a flame-retardant and antistatic polypropylene fiber composition. The composition includes, by weight, 75-95 parts of a flame-retardant and antistatic polypropylene composition,5-25 parts of a polyolefin and / or elastomer, and 0.01-0.25 part of a slipping agent. The flame-retardant and antistatic polypropylene composition includes a flame retardant, and the flame retardant includes a coordination compound formed by phosphine oxide and transition metal salts. The invention simultaneously provides flame-retardant antistatic polypropylene fibers prepared from the flame-retardant and antistatic polypropylene fiber composition provided by the invention through a spunbonding spinning method, and provides flame-retardant and antistatic polypropylene non-woven fabrics prepared from the fibers. The flame-retardant and antistatic polypropylene non-woven fabrics have the characteristics of good filtering performance, and small residual deformation, and have a good touch sense, and flame retardant and antistatic properties.

Description

technical field [0001] The invention belongs to the technical field of polymer materials and plastic processing, and in particular relates to a flame-retardant and antistatic polypropylene fiber composition and fibers and non-woven fabrics prepared therefrom. Background technique [0002] Polypropylene resin is widely used in the manufacture of non-woven fabrics due to its excellent mechanical formability, mechanical properties, high heat resistance, high cost performance and recyclability, and is used in medicine and hygiene (medical masks, surgical gowns) , labor protection and personal protection (dust masks, air purifier filter elements), personal hygiene products (sanitary napkins, diapers, cotton wipes) and other fields. [0003] Among them, in recent years, the society has higher requirements on the filterability of non-woven products in the field of environmental protection (such as PM2.5 protection) and health and hygiene (infectious diseases that can be transmitted...
