Abstract

The invention discloses a halogen-free flame-retardant low-dielectric-loss glass fiber reinforced polypropylene material, and belongs to the technical field of high polymer materials. The halogen-freeflame-retardant low-dielectric-loss glass fiber reinforced polypropylene material is prepared from the following components in parts by weight: 35 to 80 parts of polypropylene resin, 10 to 40 parts of low-dielectric-loss glass fiber and 1 to 4 parts of halogen-free flame retardant; and the dielectric loss of the low-dielectric-loss glass fiber at the frequency of 4-4.5 GHz is 4*10 <-2>-5*10 <-2>.According to the product, the halogen-free flame retardant with specific content and the glass fiber material with specific dielectric loss coefficient are added into the polypropylene resin, so thatthe original mechanical properties of the polypropylene resin can be effectively retained, the dielectric loss of the material is relatively low, and the thermal deformation temperature and flame retardancy of the material are also improved, and the material meets high use requirements in the field of electronic products. The invention further discloses a preparation method of the product. The preparation method is simple in operation steps and low in requirements for preparation equipment and achieves industrial large-scale production.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a halogen-free flame-retardant low dielectric loss glass fiber reinforced 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 technical ...
