Problems solved by technology

Prolonged contact will cause its appearance to ignite spontaneously due to excessive temperature and cause fire, which will bring disasters that are difficult to add to the masses.
At present, the simple flame retardant modification of PET through flame retardants can only simply prevent the burning of the material at a single short-term fire source, but cannot prevent its spontaneous combustion when it is exposed to high heat for a long time
At the same time, after adding a flame retardant, the toughness of the material after molding, especially the toughness of thin-walled materials, is difficult to guarantee

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a flame-retardant reinforced PET material with high glow wire temperature and a preparation method thereof. Background technique [0002] Polyethylene terephthalate (PET) is an engineering plastic with excellent comprehensive properties. PET has excellent mechanical properties, high rigidity, high hardness, good toughness, impact resistance, friction resistance and creep resistance. Good chemical resistance, soluble in cresol, concentrated sulfuric acid, nitrobenzene, trichloroacetic acid, chlorophenol, insoluble in methanol, ethanol, acetone, alkanes, etc. It itself is mainly blown into various bottles, used as containers, and spun into fibers and other applications. As an engineering plastic, it can replace nylon and polybutylene terephthalate in the electronic appliances and automobile industries. [0003] At present, there are many flame retardant literatures on PE...
