［摘要］采用三種不同的硅烷單體，利用有機-無機雜化技術制備硅烷-硅溶膠雜化材料，并針對雜化材料的類型、雜化比等因素對水泥基材料力學性能、防水性能、抗氯離子侵蝕性能的影響進行較為系統(tǒng)的研究。結果表明，通過有機-無機雜化反應，可制備出性能穩(wěn)定的硅烷-硅溶膠雜化材料，且隨著烷基碳數(shù)的增加，雜化材料的穩(wěn)定性有所提高。硅烷中添加硅溶膠一定程度地降低了水泥基材料的強度；硅烷-硅溶膠雜化材料可降低砂漿的吸水率，且隨著雜化材料用量的增加，水泥砂漿的防水性能明顯提高；三種雜化材料均具有較為明顯的抵抗氯離子侵入混凝土的能力，且辛基三乙氧基硅烷-硅溶膠雜化材料抵抗氯離子侵蝕的能力最好。

Abstract:Three kinds of silica sol monomers were used, silica sol and silane hybrid material were prepared with organic-inprganic hybrid reaction. The effects of types and hybrid ratio of hybrid material on the mechanical properties, water resistance and resistance to chloride ion penetration of cement-based materials were investigated. The results show that a stable silica soil and silane hybrid material can be made with organic-inorganic hybrid reaction. Moreover, the stability of the hybrid material increases with the increasing of more alkyl groups and carbon number. Silica sol decreases the strength of cement-based materials to some extent. The silica sol and silane hybrid materials decrease the water absorption of mortar, and water resistance can be enhanced markedly with the increase of hybrid material dosage. The three kinds of hybrid materials greatly improve the concrete′s ability to resist chloride ion penetration, especially octyltriethoxysilane-silica does.
Keywords:silica sol and silane hybrid material; hybrid ratio; cement based material; water resistance; resistance to chloride ion penetration
