Thermoplastic resin composition containing titanium dioxide pigment, and process for preparing same

Includes thermoplastic resins and titanium dioxide (TiO2) pigments and specific methods for measuring moisture content of resin composition for 10-1,400ppm. Optimization of resin combination property is through following method preparation of: (I) in 100 weight copies of TiO2 pigment of flow of powder layer will be 0.1-0.3 weight copies of organic poly silicon oxygen n-atomization; (ii) will 1-5 weight copies of metal SOAP and 100 weight copies of TiO2 pigment mixed; (iii) in 70-200 ℃ of temperature Xia will by obtained of mixture heat treatment 10 minutes-2 hours; and then (iv) will thermoplastic resin and heat treatment had of mixture mixed. When TiO2 pigment that contains 20-60wt%, the resin composition for coated paper or film. When TiO2 pigment that contains 30-80wt%, the resin composition for use as preparation for coated paper or film resin composition for masterbatch.
