Problems solved by technology

[0003] In the related art, the flame retardant materials are inorganic aluminum hydroxide and magnesium hydroxide, but the addition amount is relatively large, and it must reach more than 40% to have a flame retardant effect. High flame retardant additions have a greater impact on the mechanical properties of polypropylene; and Although halogen-based organic flame retardants can guarantee the performance of polymer materials, they will release toxic and carcinogenic substances when burned, which greatly restricts their applications.

Abstract

The invention discloses a flame-retardant polypropylene composite material as well as a preparation method and application thereof. The composite material is prepared from the following raw materials: modified polypropylene and polypropylene functional master batch, wherein the modified polypropylene is prepared from the following raw materials: low-isotacticity polypropylene, long glass fibers, a compatilizer, an antioxidant I and a lubricant I; and the polypropylene functional master batch is prepared from the following raw materials: polypropylene powder, a halogen-free flame retardant, a flexibilizer, a light stabilizer, a laser engraving agent, an antioxidant II and a lubricant II. The flame-retardant polypropylene composite material prepared by the invention has the characteristics of high strength, high modulus, weather resistance, warping resistance, flame retardance, high glowing filament, laser marking capability and the like, and can be applied to preparation of plastic parts such as 5G radomes, automobile luggage racks and storage battery covers.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a flame-retardant polypropylene composite material and its preparation method and application. Background technique [0002] Polypropylene is a polymer material, non-toxic, low density, light weight, excellent mechanical, electrical insulation and chemical resistance, and is widely used in electronics, construction, textiles, decoration, machinery and other fields; because polypropylene is flammable When burning, it will release toxic corrosive gas and a lot of smoke, which will bring hidden dangers to life and property. It is of great significance to improve the flame retardancy of polypropylene materials. [0003] In the related art, the flame retardant materials use inorganic aluminum hydroxide and magnesium hydroxide, but the addition amount is relatively large, and it must reach more than 40% to have a flame retardant effect. High flame retardant additions have a greater imp...
