(200℃*10min)。
Further, by adjusting the rational proportion of each raw material further, the ratio when 168 and 1300 is 1:
2；When the gross weight of antioxidant and color inhibition agent is the 1% of polyester resin, protecting light rate is more than 50 (240h
QUV/%), aberration is only 0.13 (200 DEG C of * 10min).
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention will be further described.
Embodiment 1:
First, on the premise of without antioxidant and color inhibition agent, weigh former by following mass fraction
Material, prepares polyester resin
Synthesis reactor temperature is risen to 90-100 DEG C, add ethylene glycol, neopentyl glycol, trimethylolpropane,
Terephthalic acid (TPA), adipic acid, M-phthalic acid, Mono-n-butyltin, rise under the protection of reaction nitrogen
240-245 DEG C of maintenance of temperature, until the acid number of thing is 10-20mgkoh/g, is cooled to 210-220 DEG C, puts into
End-capping reagent M-phthalic acid, or/and adipic acid, is warming up to 242-245 DEG C of maintenance, until reactant acid number is
