| Abstract: | In this paper, HIPS/ nano TiO 2 composites have been prepared by surface pre treatment of nano TiO 2 and selecting special macromolecule dispersing agent TAS and master batch manufacturing technique. The results show that the notched impact strength,tensile strength and elastic modulus of HIPS/nano TiO 2 composites rise to the maximum when the nano TiO 2 content is 2 %.Nano TiO 2 has both toughening and reinforcing effect on HIPS.The heat deflection temperature, flame retardance and heat aging resistance of HIPS/nano TiO 2 composites are also obviously improved as the nano TiO 2 content increases. HIPS/nano TiO 2 composites are also a non Newtonion and pseudoplastic fluid. |
