Poly (trimethylene terephthalate), as a new polyester material, has excellent properties, but its flammability limits its application range. In order to improve the flame retardant properties of ethylene terephthalate. In this paper, the flame retardant modification of poly (ethylene terephthalate) resin (PTT) was carried out by using non-halogen expansion EPFR-300A as flame retardant modifier, and maleic anhydride grafted polyolefin elastomer (POE-g-MAH) as toughening agent. The effects of flame retardant and toughening agents on the mechanical, thermal and flame retardant properties of PTT resin were studied by thermal gravimetric analyzer (TGA), differential scanning calorimeter (DSC), scanning electron microscope (SEM) and mechanical properties. The results show that the mechanical properties of PTT resin are improved by the addition of POE and POE-g-MAH. When mass fraction is the same, toughening effect of POE-g-MAH on PTT resin is better than that of POE, and mechanical properties are the best when mass fraction of POE-g-MAH is 7%. When the same content of toughening agent is added, mass fraction of EPFR-300A reaches 20%, flame retardant property is the best, limit oxygen index reaches 28.0%, and vertical combustion flame retardant grade reaches UL94 V-0. The compatibility between EPFR-300A flame retardant and PTT resin is good, and it can effectively promote PTT resin into carbon and improve flame retardant properties of the material.
