Nano-modified PET engineering plastic and preparation method thereof

[0039] Embodiment one, a kind of nano-modified PET engineering plastics, comprises the material that following weight ratio is arranged, specifically:

[0040] PET polyester 50%

[0041] Fiberglass 30%

[0042] Lubricant 0.4%

[0043] Antioxidant 0.6%

[0044] Toughener 2.5%

[0045] Flame retardant 13%

[0046] Synergistic flame retardant 2.5%

[0047] Nano nucleating agent 1%;

[0048] Among them, the lubricant is pentaerythritol stearate, the antioxidant is tetrakis [methyl-β-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate] pentaerythritol ester and phosphite tris(2 , 4-di-tert-butylphenyl) ester compound, tetrakis[methyl-β-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate] pentaerythritol ester in antioxidant The weight ratio of tris(2,4-di-tert-butylphenyl) to phosphite is 1:1, that is, tetrakis[methyl-β-(3,5-di-tert-butyl-4-hydroxy Phenyl) propionate] pentaerythritol ester and tris (2,4-di-tert-butylphenyl) phosphite account for 0.3% by weight of the total material; th...
