Flame-retardant polypropylene material as well as preparation method and application thereof

Abstract

The invention discloses a flame-retardant polypropylene material as well as a preparation method and application thereof. The flame-retardant polypropylene material is prepared from the following rawmaterials in terms of 100 parts by mass: 72-85 parts of copolymerization polypropylene resin, 8-15 parts of brominated flame retardant-antioxidant 1010 compound, 3-6 parts of antimonic flame retardant, 1-3 parts of titanium dioxide, 0.5-1.2 parts of lubricant, 1-2 parts of antistatic agent, 0.5-1.2 parts of antioxidant and 0.3-1 part of antibacterial agent. The flame-retardant polypropylene has agood antistatic effect, has a surface resistance of 108-109 omegas, is high in glossiness, does not produce flame retardant precipitate, has a flame retardant rating of UL94V-0, and has the advantagesof being capable of inhibiting bacterial growth for a long time, being good in antibacterial effect and the like. The preparation method is simple and efficient, easily guarantees flame retardance and high-brightness white color of the material, and is high in production efficiency.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a flame-retardant polypropylene material and its preparation method and application. Background technique [0002] Polypropylene is one of the five general-purpose resins. It has excellent properties such as light weight, easy processing, and chemical resistance. It is widely used in chemical, electrical, packaging and other industrial fields. However, with the increasing demand for polypropylene in industries such as construction, automobiles, ships, and electrical and electronic insulation materials, people's requirements for its flame retardancy are also increasing. Polypropylene itself is a flammable material, its oxygen index is only 17% to 18%, and its char formation rate is low, and it is easy to produce molten droplets when burning, which will cause the surrounding combustible materials to ignite, and the surface resistance of polypropylene is greater than 10 14 Ω, poor...

AI Technical Summary

Problems solved by technology

Conventional flame-retardant polypropylene is not high-gloss, and some flame retardants are easy to precipitate, and the electrostatic effect is obvious, and the finished product is easy to adhere to dust

[0004] At present, the modified materials related to polypropylene flame retardant materials include: CN106117805A discloses an antibacterial flame retardant polypropylene plate, which has a bactericidal rate of more than 93% for Escherichia coli and Staphylococcus aureus, and a surface resistivity of 10 8 Ω, but its antibacterial agent and antistatic agent are all obtained by compounding, the synthesis is more complicated, and the input of raw materials is more; CN106810753A discloses a V-0 flame-retardant antistatic polypropylene material, when its antistatic agent reaches 20 parts, its surface resistivity can reach 10 8 Ω, the effect is poor, therefore, how to modify the polypropylene flame retardant material to make it a high gloss, antistatic and antibacterial flame retardant material to meet the market demand is of great significance
