Titanium dioxide nanoparticles （TiO 2 ） treated with anionic surfactant sodium dodecyl sulfate （SDS） were dispersed into urushiol acetal epoxy Varnish in different mass ratio to get composite paints. Composite paints were characterized by infrared spectrometry（FT-IR）, transmission electron microscope（TEM）, scanning electron microscope（SEM）,and its mechanical properties, alkali-resistant, acid-resistant and heat-resistant abilities were measured. The results indicate that there are strong hydrogen bond reactions between urushiol acetal epoxy varnish and titanium dioxide nanoparticles. And adding TiO 2 nanoparticles can increase the alkali-resistant, acid-resistant and heat-resistant abilities. Compared with the paint without nanoparticles, adding 4% or 5% nano-TiO 2 results in 56.7% increase of the alkali-resistant ability and 50 ℃ increase of the highest temperature of heat-resistant respectively of nanometer composite paint. 纳米TiO2 纳米复合涂料 漆酚缩醛环氧清漆 nano-TiO2 nanometer composite paint urushiol acetal epoxy varnish TQ630.7 国家自然科学基金资助项目（30170757） 2005-04-01 2021-04-01 4
