Embodiment 1
[0047]
[0048] Mix the copolymerized flame retardant CEPPA and ethylene glycol at a molar ratio of 1:1.2, and react at 100°C for 1 hour to obtain the reaction product CEPPA-EG. Mix tetraethoxysilane (TEOS) and ethylene glycol at a molar ratio of 1:4, and react under the action of catalyst HCl to obtain tetrakis (2-hydroxyethyl) orthosilicic acid solution. Mix terephthalic acid and ethylene glycol slurry at a molar ratio of 1:1.05 to prepare slurry. The prepared slurry was mixed with the catalyst tetrabutyl titanate and then put into an esterification reactor for the first esterification reaction. The temperature of the first esterification reaction was 225° C., the reaction time was 4 hours, and the relative pressure of the reaction was 0 MPa. When the esterification reaction reaches 82%, add sorbitol and polyethylene glycol (PEG-200) to carry out the second esterification reaction, the second esterification reaction temperature is 240°C, and the esterification reaction ti...

[0050]
[0051] Mix the copolymerized flame retardant CEPPA and ethylene glycol at a molar ratio of 1:1.8, and react at 100°C for 1 hour to obtain the reaction product CEPPA-EG. Hydroxyl-terminated silicone oil and ethylene glycol are mixed in a molar ratio of 1:4.4, and the catalyst SiCl 4 Under the action of the reaction, the hydroxyl-terminated silicone oil-EG solution is obtained. Mix terephthalic acid and ethylene glycol slurry at a molar ratio of 1:2.0 to prepare slurry. Mix the prepared slurry with ethylene glycol antimony, antioxidant 1010 and trimethyl phosphate, and then add it to the esterification reactor for the first esterification reaction. The temperature of the first esterification reaction is 250°C, and the reaction time is 0.5h , the relative pressure of the reaction is 0.4MPa. When the esterification reaction reaches 95%, 1,2-propanediol and polyethylene glycol (PEG-400) are added to carry out the second esterification reaction. The temperature of the ...
