以苯丙乳液、粉煤灰、水泥、功能助剂为原料，考察粉煤灰与水泥的不同添加组合对混凝土防腐涂料性能（包括涂层柔韧性、耐冲击性、吸水性、抗氯离子渗透性、耐中性盐雾性）的影响，制备了一种粉煤灰基混凝土防腐涂料。研究结果表明，随着粉煤灰添加量逐渐增加，涂层的表观性能越好，抗氯离子渗透性提高，吸水性越来越低，粉煤灰添加量为60％的涂层性能最好，耐中性盐雾也满足标准GB／T 1771—2007要求。通过XRD和SEM对该涂料的防腐蚀机理进行了分析，加入60％超细粉煤灰的涂层中生成了更多的水化产物使其结构致密，阻碍了腐蚀物质的进入，起到更好的防护作用。
The organic styrene-acrylic emulsion， fly ash， cement and functional additives were used as the raw materials to prepare a kind of fly ash-based concrete anticorrosive coatings. The coatings performance varying with different ratio of fly ash and cement were investigated， including coating flexibility， impact resistance， water absorption， resistance to chloride ion permeability and neutral salt spray resistance. The results showed that the apparent performance of the coating was improved with the increase of the amount of fly ash. Meanwhile， the resistance to chloride ions permeability increased and the water absorption decreased. The coating comprising fly ash 60％ had the optimal comprehensive performance， and the neutral salt spray resistance met the standard requirements described in GB／T 1771—2007. The analysis of XRD and SEM showed that the addition of the cement and fly ash could produced more hydrated products which densified the film structure and inhibit the permeation of corrosive substance. The better protection was obtained.
