绢云母增强无机硅酸锌涂料耐蚀抗磨性及耐水性

 研究探讨了绢云母在无机硅酸锌涂料中添加改性的应用,采用极化曲线、干磨损实验、浸泡及水冲刷实验等测试手段,对比考察了添加绢云母前后涂层的腐蚀特性、摩擦磨损及耐水性能。结果表明,绢云母具有的良好耐腐蚀性能,以及绢云母与腐蚀产物一起对涂层孔隙的协同填塞作用,降低了涂层的腐蚀速率;绢云母的层片状结构降低了涂层的摩擦系数,减轻了涂层的塑性变形,阻止了涂层内部裂纹的产生和扩展,增强涂层耐磨性能;绢云母的添加可以促使涂层内部形成一种致密的层网状结构,增加了涂层的致密性、抗渗透性和涂层强度,从而提高了涂层的耐水性。

Reinforced Zinc-Silicate Coatings on Anti-Wear Anticorrosion and Water Resistance by Adding Sericite

Reinforced zinc-silicate coating by adding sericite has been investigated. Contrasting wear resistance, corrosion resistance and water resistance performance of the modification coating and zinc-silicate coating by polarization curve, attrition experiment, immersion and water washout experiment. The research result shows that the sericite's corrosion resistance, and the synergistic effect of porous coating filled by the sericite and the corrosion products reduced the corrosion rate of corrosion. The sericite play a positive role. It enhanced wear resistance by reducing the friction coefficient, reducing coating plastic deformation, internal cracks in the coating to prevent the generation and expansion. The paint film interior may form one kind of compact level network structure, increases the coating the compactness, the enhancement paint film impermeability and the paint film intensity, enhances the water resistance. Primer coating is not limited to, expanding the application of coating space.
