The invention discloses a PBT environment-friendly and flame-retardant material toughened and reinforced by blending elastomer and micrometer particles. The PBT environment-friendly and flame-retardant material comprises components by mass: 50%-70% of PBT, 18%-25% of a halogen-free flame retardant, 5%-20% of elastormer, 5%-20% of the micrometer particles, 0.1%-0.5% of a surface treating agent, 0.2-1.5% of a lubricant, 0.1%-1% of an antioxidant and 0-0.5% of a light stabilizer. Compared with a conventional PBT material, the prepared PBT has high notch impact strength and good toughness, keeps relatively good strength, and can greatly increase rigidity, heat resistance and processability. At the same time, the used halogen-free flame retardant has the advantages of security, smoke-suppressing, no toxicity, environment protection and low cost. The PBT material has high flame-retardant property and excellent comprehensive properties, and can be used as materials for preparing electronics, electrics, automobile industries and mechanical components.
