Abstract

The invention discloses a PTT polyester based weather resistant flame retardant composite material. The material comprises the following components by mass: 80%-95% of PTT, 5%-20% of an inorganic filler, 0.1%-0.5% of a coupling agent, 0.1%-0.3% of a composite flame retardant, 0.5%-2% of an ultraviolet stabilizer, 0.1%-0.5% of a nucleating agent, 0.1%-0.5% of an antioxidant, and 0.1%-1% of a lubricant. The composite flame retardant is a compound of an iodate flame retardant potassium perfluorobutanesulfonate and a melt drip resistant agent polytetrafluoroethylene in a mass ratio of 1:1. The PTT polyester based weather resistant flame retardant composite material provided by the invention has good flame retardant properties and weathering stability, also has good strength, rigidity and heat resistance, good flame retardant effect, and limiting oxygen index up to over 32%, and is in accordance with the requirements of no halogen, high efficiency, melt drip resistance and UL94V-0 grade flame retardance.
