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.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a weather-resistant and flame-retardant composite material based on PTT polyester. Background technique [0002] Polytrimethylene terephthalate (PTT), as a new type of polyester polymer material with excellent comprehensive properties, has been widely used in the fields of fibers, films, engineering plastics, etc., but unmodified PTT has low notched impact strength, The defects of high notch sensitivity, poor flame retardancy, and easy aging greatly limit the wider application of PTT in various fields. Contents of the invention [0003] The object of the present invention is to provide a weather-resistant and flame-retardant composite material based on PTT polyester. [0004] The technical solution adopted by the present invention to solve the technical problem is: a weather-resistant and flame-retardant composite material based on PTT polyester. Joint agent 0.1%~0....
