The invention discloses a fame-retardant
polyester material with a high glow wire ignition temperature and a preparation method thereof. The
flame-retardant
polyester material with a high glow wire ignition temperature is composed of the following components in parts by weight: 100 parts of
polyester resins, 15-50 parts of
bromine-series
flame retardant, 5-20 parts of synergistic
flame retardant, 0-20 parts of
toughening agent, 0-80 parts of carbon forming agent, 5-40 parts of hot
oxygen barrier agent, 0-120 parts of fibrous reinforcing agent and 0-10 parts of
processing aid. The preparation method of the flame-retardant polyester material with a high glow wire ignition temperature comprises:
drying the polyester resins, mixing with other components to obtain a premixed material, then feeding the premixed material into a twin-screw extruder, melting and plasticizing, kneading and mixing, extruding, drawing, cooling,
pelletizing,
drying and finally packaging. The flame-retardant polyester material with a high glow wire ignition temperature has the advantages of low cost, high glow wire ignition temperature, similar
mechanical strength to ordinary flame-retardant polyester and wide application range.
