AI Technical Summary

Problems solved by technology

High flame retardant addition has a great influence on the mechanical properties of polypropylene fibers, and greatly increases the cost of materials
When the content of intumescent flame retardant in polypropylene fiber is low, the thickness of the foamed carbon layer formed during combustion is relatively thin. When polypropylene is burned, it is heated and melted, and the thinner foamed carbon layer is unstable on the surface of the melt and is prone to Slipping or cracking will affect the flame retardant performance

Embodiment 1

[0038] 1) Preparation of coating layer composition pellets

[0039] Add 20 parts by weight of high-flow PP, 30 parts by weight of low-flow PP, 35 parts by weight of thermoplastic elastomer, 2 parts by weight of flame retardant (A), 8 parts by weight of flame retardant (B), and 3 parts by weight of EVA into the mixer at high speed Run for 5 minutes (frequency 50Hz, temperature reaches 45°C), add 0.11 parts by weight of antioxidant 1010, 0.09 parts by weight of light stabilizer 944, 0.2 parts by weight of ultraviolet stabilizer UV-326, stir for 2 minutes, add 5 parts by weight of titanium dioxide, 0.13 parts by weight of slip agent EBO and 8 parts by weight of talcum powder were stirred for 5 minutes. Put the evenly stirred raw materials into the bin to be extruded and feed them into the twin-screw extruder through the feeder (30r / min), and adjust the temperature of the twin-screw extruder (12 temperature sections): 140°C—145°C—145°C— 150°C—155°C—160°C—160°C—160°C—158°C—158°C—1...

Abstract

The invention relates to flame-retardant polypropylene composite fabric and a product thereof. The flame-retardant polypropylene composite fabric has a skin-core structure and uses polypropylene filaments as the core and an elastomer coating layer material as the skin, and the elastomer coating layer material is prepared by polypropylene resin, thermoplastic elastomers, a flame retardant and auxiliary materials. The flame-retardant polypropylene composite fabric is good in mechanical performance, good in flame retardance and low in permanent deformation. The flame-retardant polypropylene composite fabric can be independently prepared into textiles and shell fabric or blended with other fibers or fabric to obtain blended yarn, textiles and shell fabric.

Description

technical field [0001] The invention relates to a flame-retardant polypropylene fabric and a fabric made of the fabric, belonging to the field of textile products. Background technique [0002] Polypropylene fiber officially started industrial production in 1957 and is a rising star among synthetic fibers. Because polypropylene fiber has the characteristics of simple production process, low relative density (0.91g / ml), low raw material and production cost, and high fiber strength, it has developed rapidly. At present, polypropylene fiber is the fourth largest variety of synthetic fiber. The biggest disadvantage of polypropylene fiber is its flammability. Polypropylene is a polymer material containing only hydrocarbon elements. Its oxygen index is low (only about 18), and it is extremely flammable. It also generates a large amount of molten droplets when it burns. , easily spreads flames. The flammability of polypropylene fiber limits its application to a large extent, so e...
