Problems solved by technology

Flame-retardant polypropylene products are mostly prepared from halogen-containing systems, but such modified materials are not environmentally friendly and highly harmful; while the glow wire of the polypropylene material itself acts at 650°C, the glass fiber contained in the modified polypropylene is in the system. The aspect ratio shape of the material has a negative effect on the reduction of the surface melt of the material glow wire and the timely loss of heat, resulting in the technical difficulty that glass fiber reinforced polypropylene materials cannot achieve high glow wire
In addition, the resistance of the polypropylene material in the existing products is not significant, and it is easy to precipitate under extreme conditions (such as high temperature and high humidity), making it impossible to use normally, and it is also unable to effectively prevent the generation of static electricity

Abstract

The invention discloses a high-temperature-resistant high-humidity-resistant halogen-free flame-retardant antistatic polypropylene material, and belongs to the technical field of high polymer materials. According to the high-temperature-resistant high-humidity-resistant halogen-free flame-retardant antistatic polypropylene material disclosed by the invention, a halogen-free flame retardant, a coupling agent and expandable graphite with specific contents are added into polypropylene resin, and the expandable graphite is modified by utilizing the coupling agent and then the modified graphite ismatched with other components, so that the original mechanical properties of the polypropylene resin can be effectively retained, the thermal deformation temperature and the flame retardance of the material are remarkably improved, and meanwhile, the material can be prevented from being separated out in a high-temperature and high-humidity environment; the material also meets the GWIT standard ofglowing filaments at 850 DEG C, has excellent antistatic performance, and particularly meets the high use requirements of the glowing filaments in the field of electronic products. The invention further discloses a preparation method of the high-temperature-resistant high-humidity-resistant halogen-free flame-retardant antistatic polypropylene material. The preparation method is simple in operation steps and low in requirements for preparation equipment, and can achieve industrial large-scale production.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-temperature, high-humidity, halogen-free, flame-retardant and antistatic polypropylene material. Background technique [0002] Polypropylene material is a thermoplastic resin obtained by polymerizing propylene molecules. It is widely used in various industries because of its low density and excellent toughness, as well as good electrical properties and high-frequency insulation. Flame-retardant polypropylene products are mostly prepared from halogen-containing systems, but such modified materials are not environmentally friendly and highly harmful; while the glow wire of the polypropylene material itself acts at 650°C, the glass fiber contained in the modified polypropylene is in the system. The aspect ratio shape of the material has a negative effect on the reduction of the surface melt of the material glow wire and the timely loss of heat, resulting in the tech...
