Thermoplastic resin composition containing titanium dioxide pigment, and process for preparing same |
摘要 |
<p>A resin composition comprising a thermoplastic resin and a titanium dioxide (TiO2) pigment and having a moisture content of 10 - 1,400 ppm as determined by a specific method. A preferable resin composition is made by (i) atomizing 0.1 - 3.0 wt. parts of an organopolysiloxane within a fluidized powder layer of 100 wt. parts of TiO2 pigment; (ii) mixing 1 - 5 wt. parts of a metallic soap with 100 wt. parts of the TiO2 pigment; (iii) heat-treating the thus-obtained mixture at 70 - 200 DEG C for 10 min - 2 hours; and then (iv) mixing a thermoplastic resin with the heat-treated mixture. The resin composition is used for coating paper or film, when it contains 20 - 60 wt.% of TiO2 pigment. The resin composition is used as a master batch for the preparation of a resin composition for coating paper or film, when it contains 30 - 80 wt.% of TiO2 pigment.</p> |
