Abstract

The invention discloses a PTT polyester flame retardation composition with excellent mechanical properties. The composition comprises the following ingredients, by weight, 60%-80% of PTT, 8%-12% of glass fibers, 2%-10% of calcium carbonate composite particles, 4%-8% of MBS, 4%-8% of flame retardants, 0.5%-2% of light stabilizing agents, 0.1%-0.5% of anti-oxidants and 0.1%-1% of lubricants. The calcium carbonate composite particles are calcium carbonate nanoparticles with surfaces after grafting of styrene and methyl acrylate dual monomers. The beneficial effects are that the PTT polyester flame retardation composition has excellent flame retardation performance and heat resistance, and also has good integrated mechanical properties of tensile strength, bending strength and impact intensity; the processability is good, the chemical resistant stability is excellent, the cost is low, and the appearance is good.
