摘要：目前，无机纳米材料改性高分子聚合物成为人们寻找优良水性涂料成膜物质的研究热点。本文通过一步法将自制改性纳米TiO2与丙烯酸、苯乙烯等单体在引发剂作用下制备一种硬度高、耐水性能强、力学性能优异的水性纳米TiO2高固含量的苯丙复合材料。研究表明，当TiO2含量0.8 wt%时，复合材料的综合性能最优，涂膜硬度2H，耐水性能35h,拉伸强度达12.5 MPa。

Abstract: at present, the polymer modified by inorganic nano materials has become a research hotspot in the search of excellent film-forming materials for waterborne coatings. In this paper, a kind of high solid content water-borne Nano-TiO2 Composite with high hardness, strong water resistance and excellent mechanical properties was prepared by one-step reaction of modified nano-TiO2 with acrylic acid, styrene and other monomers under the action of initiator. The results show that when the TiO2 content is 0.8 wt%, the composite has the best comprehensive properties. The hardness of the coating is 2h, the water resistance is 35h, and the tensile strength is 12.5mpa.<br>
