The composite material comprises the following ingredients, by weight, 65%-90% of PTT, 5%-20% of modified calcium carbonate particles, 4%-10% of EVA, 1%-3% of antistatic agents, 0.5%-2% of light stabilizing agents, 0.1%-0.5% of anti-oxidants, 0.1%-1% of lubricants and 0.05%-0.1% of sulfonate flame retardants. The modified calcium carbonate particles are ground calcium carbonate nanoparticles with surfaces processed by aluminum titanium composite coupling agents and with a particle of 10-80nm. The antistatic agents are high-molecular permanent antistatic agents. The sulfonate flame retardants are one or some of PPFBS, KFBS, NaFBS and KSS. The beneficial effects are that the composite material has excellent flame retardation and permanent antistatic performance, the processability is good, the intensity is high, the impact resistance is excellent, the chemical-resistant stability is good, and the cost is low.
