The polypropylene material produced by the invention has excellent weather resistance, flame retardancy, electrical resistance, temperature impact resistance and mechanical property, and is cheap in the materials, simple and easy to process and suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a multi-performance polypropylene material. Background technique [0002] Polypropylene has excellent mechanical properties, good heat resistance, high chemical stability, excellent electrical insulation, and good processability. It is a general-purpose plastic with excellent comprehensive properties. However, due to its saturated hydrocarbon structure and the existence of tertiary carbon atoms, polypropylene is extremely flammable and has poor weather resistance. [0003] Halogenated flame retardants are the most effective flame retardant additives for polyolefin materials with less addition, high flame retardant efficiency, and minimal impact on polymer properties. The commonly used varieties mainly include decabromodiphenylethane, hexabromocyclic Dodecane, octabromoether, octabromo-S ether, tris (2,3-dibromopropyl) isocyanate (TBC), tris (2,2-dibromomethyl-3-bromo...

AI Technical Summary

Problems solved by technology

[0004] The currently disclosed halogen-based flame-retardant and weather-resistant technologies all use ultraviolet absorbers and / or hindered amine light stabilizers, and have not yet solved the problem of using only carbon black as a weather-resistant modifier, that is, high carbon black content (>1wt%) ), how to prepare flame-retardant and weather-resistant polypropylene; and there are the following common deficiencies, which affect its use in various fields:

[0005] ① Ultraviolet absorbers and hindered amine light stabilizers are organic polar small molecules, which have problems of saturation and volatilization with non-polar polypropylene resins, and under long-term ultraviolet rays, there are side reactions such as degradation and even failure problems.

[0006] ② Commonly used hindered amine light stabilizers will react with brominated flame retardants due to their high alkalinity, and there is a problem of confrontation between weathering agents and flame retardants

[0007] ③ Compared with carbon black, UV absorbers and hindered amine light stabilizers are much more expensive

After searching, it is found that although there are some high temperature resistant and non-slip polypropylene materials, they lack antistatic function and cannot meet the actual safe use, causing potential accident hazards
