Embodiment 1
[0034] Preparation process of nano-modified slices:
[0035] First, on the continuous polyester equipment, use terephthalic acid (PTA) and ethylene glycol (EG) monomers to continuously and stably meter and feed them into the slurry tank according to the molar ratio of PTA and EG at a ratio of 1:1.25 In beating, add nano-zinc oxide, nano-copper oxide, and matting agent titanium dioxide in the beating kettle, wherein the molar ratio of the addition of nano-zinc oxide to terephthalic acid is 5.8%, and the addition of nano-copper oxide to the amount of terephthalic acid The mol ratio is 0.56%, and the mol ratio of the addition of matting agent titanium dioxide and phthalic acid is 2.5%;
[0036] Then, the above slurry is continuously and stably transported to the Esterification-I and Esterification-II reactors, and the stabilizer is continuously added to the Esterification-II reactors at the same time to control the esterification rate to 97.5%, and the viscosity of the melt is ...
