Abstract

The invention relates to a manufacturing method of an enhanced type flam-retardant anti-aging polyester film. Magnesium hydrate crystal whisker, calcium carbonate crystal whisker, barium sulfate, microencapsulation red phosphorus fire retardant and the like, which have flame-retardant and material-enhancing functions, are ground with ethylene glycol, p-hydroxybenzoic acid and the like to obtain flame-retardant and function-enhancing alcohol; an anti-aging material triazine-5 light stabilizer, rutile titanium dioxide, a high-temperature antioxygen and a UV-327 ultraviolet light absorber are mixed with ethylene glycol and the like, and are ground to react to obtain a compound anti-aging agent; purified terephthalic acid is mixed with the ethylene glycol and the flame-retardant function-enhancing alcohol according to a certain proportion, and is subjected to copolycondensation; the compound anti-agnign agent is continuously added in the later stage of esterification reaction to obtain enhanced type flame-retardant anti-aging polyester; the enhanced type flame-retardant anti-aging polyester is stretched in a dual-axis mode and is thermally shaped to be manufactured into the enhanced type flame-retardant anti-aging polyester film.

Description

technical field [0001] The invention relates to a method for manufacturing a reinforced flame-retardant and anti-aging polyester film, which belongs to the technical field of plastic product manufacturing. Background technique [0002] Polyethylene terephthalate (polyester) is made by polycondensation reaction of terephthalic acid (PTA) and ethylene glycol (EG), because of its high melting temperature (Tm) and vitrification Transition temperature (Tg), and has good processing rheology, mechanical properties, wear resistance, creep resistance and electrical insulation, and is widely used in synthetic fibers, bottle flakes, films and other fields. Polyester aging generally refers to the degradation of molecular chains and cross-linking reactions of polyester under external conditions (wind, sun, rain, cold, heat) during processing, storage and use, resulting in poor performance and affecting The normal use of the product is an irreversible change. Outdoor polyester products a...
