Abstract

The present invention discloses a flame-retardant composite material comprising a PET chip, an ionomer resin, MMT, kaolin, HNTS, polybrominated styrene, an antioxidant, a silane coupling agent, a lubricant and alkali-free glass fiber. The PET chip is Huarun resin with viscosity of 0.8; the kaolin is 90D; the silane coupling agent is KH-560; the lubricant is PETS; and the kaolin and the silane coupling agent are in the weight ratio of 3:10. The material is supplemented with inorganic particles to accelerate the r crystallization ate of PET, and has better overall performance, excellent strength and toughness, as well as good fire-retardant properties.
