摘　　要：以含氟二氧化硅为原料制备钙离子交换型二氧化硅(SEC-SiO_(2))防锈颜料,介绍SEC-SiO_(2)的市场情况、产品用途、制备工艺及防腐蚀性能等,研究钙离子交换型二氧化硅改性前后的物相、化学组成及硅羟基含量,改性后防锈性能有所提高。基于水性环氧酯体系,与磷酸盐体系常见防锈颜料磷酸锌进行对比,结果表明,表面羟基含量较高、钙离子含量较高、具有多孔结构和易于形成表面复合钝化层的的钙离子交换型二氧化硅防锈颜料抗盐雾测试表现优于磷酸锌。SEC-SiO_(2)防锈颜料是一种符合绿色环保、值得推广的新兴防锈颜料。The calcium ion exchanged silica(SEC-SiO_(2))anti-corrosion pigments based on fluorine-containing silica is prepared,the market,the application,the production process and the anti-corrosion properties are respectively introduced.The changes in phase,chemical composition and silicon hydroxyl context parameters before and after modification of calcium ion exchanged silica are studied.The anti-corrosion performance is improved after modification.In comparison with common anti-corrosion pigments like zinc phosphate under waterborne epoxy ester,the results indicate that porous structured SEC-SiO_(2) which is prone to form complex passivated layer,has a higher surface hydroxyl content and higher calcium ion content,shows better anti-corrosion performances than zinc phosphate in the salt-spray test.SEC-SiO_(2) pigments are emerging anti-corrosion pigments that conform to green environmental protection and is worth promoting.
