  • 摘要: 以有压热闷渣为研究对象,采用超细立式粉磨机对有压热闷渣进行处理形成微粉,利用有压热闷渣微粉替代传统防腐填料与环氧树脂、二甲苯、正丁醇及聚酰胺形成有压热闷渣/环氧复合防腐涂料,研究有压热闷渣微粉对环氧复合防腐涂料涂层力学性能、防腐性能的影响,同时借助多种表征手段进行分析。研究结果表明有压热闷渣主要化学成分为CaO、Fe2O3、SiO2、MgO、Al2O3和MnO等,具有的硅酸盐特性提高了耐久性。利用超细立式粉磨机加工有压热闷渣,有利于f-CaO矿化,降低粒径增强表面活化性。粒径均匀度为2.240的有压热闷渣微粉,其添加量为5%时,有压热闷渣/环氧复合防腐涂料涂层的硬度为115.75s、附着力为3级、磨损量最小、柔韧性为4mm、阻抗模量为106.1 Ω.cm-2、腐蚀电位E为0.143 V。有压热闷渣微粉作为一种刚性粒子,将其加入环氧涂料一方面可以改善涂层的硬度、耐摩擦等力学性能,另一方面合理的粒径级配可以增大涂层的密实度,提升防腐性能。

     

    Abstract: With pressed-heat and stuffy slag as the research object, using ultra fine vertical mill for pressed-heat and stuffy slag form powder, using pressed-heat and stuffy slag powder replace traditional anti-corrosion filler, in addition with epoxy resin, xylene, butanol and polyamide form pressed-heat and stuffy slag powder/epoxy composite anti-corrosion coating, the mechanical property and anti-corrosion property of pressed-heat and stuffy slag powder/epoxy composite anti-corrosion coating was determined through a variety of characterization means analysis. The results show that the main chemical components of pressed-heat and stuffy slag are CaO, Fe2O3, SiO2, MgO, Al2O3 and MnO et al, and the silicate characteristics improve the durability. The ultra fine vertical mill is used to process the pressed-heat and stuffy slag, which is conducive to f-CaO mineralization and reduce the particle size to enhance the surface activation. When the particle size uniformity is 2.240, the added amount is 5%, the hardness of the pressed-heat and stuffy slag powder/epoxy composite anti-corrosion coating is 115.75s, the adhesion is grade 3, the abrasion loss is minimum, the flexibility is 4mm, and the impedance modulus is 106.1 Ω.cm-2, the corrosion potential is 0.143 V. As a kind of rigid particle, added epoxy coating on the one hand can enhance the hardness and friction resistance of the coating, on the other hand, reasonable particle size grading can increase the compactness of the coating and improve the anti-corrosion?property.
