Embodiment 1
[0022] 1) Preparation of in-situ polymerized titanium dioxide / polyester composite particles:
[0023] Add ethylene glycol into the reaction kettle, add terephthalic acid and various additives while stirring to prepare a slurry, pressurize to 0.2MPa under nitrogen protection; control the internal temperature of the reaction kettle to 230-250°C, and the esterification reaction At the end, the pressure is reduced to normal pressure, the temperature is lowered to 230°C, and then nano-titanium dioxide is added to disperse evenly in ethylene glycol, and then added to the reaction kettle, and the temperature is raised to 260°C. After low vacuum and high vacuum stages, the temperature in the polycondensation kettle is controlled to 275 -285°C, the vacuum degree is less than 30Pa, after reaching the required viscosity, inject nitrogen gas to pressurize and discharge, and granulate to obtain composite particles. The average particle size of the particles is controlled at 5 μm, and the co...
