钛白的吸附和有机化改性

本文通过十二烷基磺酸钠（SDS）和带有反应性基团的新型阳离子表面活性剂（CDMAAB）在TiO2／水界面上吸附，研究了有机化钛白的制备，测定了样品的吸附等温线、比表面、接触角及在液体石蜡中的粘度等物化性能，还研究了钛白的表面改性对天然橡胶力学性能的影响，结果表明上述表面改性方法是可行的。

In this paper,the prepration of organic titanium dioxide particles by using the adsorption of SDS and CDMAAB on TiO2/H2 interface was studied. The adsorption isotherm,speific surface area,contact angle,DTA and the viscosity of the sample in mineral syrup were determined. on the other hand,the effect of surfece medification of TiO2 onmechanical properties of native rubber was examined. The results showed the methed of surfece modification metionedabove was effective.
