摘要

为探究填充不同质量的无机填料CeO₂-ZrO₂-Al₂O₃(CZA)粉体对丙烯酸涂料防腐性能及各项力学性能的影响，采用共沉淀法经过干燥煅烧合成了CZA粉体样品，将得到的CZA粉末配以市场上常用的分散剂、消泡剂等助剂在丙烯酸树脂中充分分散，并以刮涂的处理方法在经过处理的铁板上制备不同质量分数的丙烯酸防腐涂层。采用XRD、SEM和EDS对CZA粉体样品进行物相分析，利用力学性能测试和电化学防腐性能测试对涂层附着力、硬度、粗糙度、弯折性能、耐磨性、拉伸强度、断裂伸长率、防腐性能等特性进行评估。结果表明，制备得到的CZA粉体为固溶体，呈现四面体结构，添加CZA粉末后，涂层硬度提高，由HB上升至1H,弯曲性能皆为1T,耐磨性能得到提高，附着力皆为1级。与没有添加CZA的丙烯酸防腐涂层相比，CZA增强了涂层的防腐性能，当填料添加质量分数为10%时，涂层防腐性能最佳。该丙烯酸类防腐涂料具有一定的防腐性能，能够有效防止腐蚀介质对材料的腐蚀，未来在防腐领域具有一定的应用前景。

Abstract

In order to investigate the effect of filling different masses of inorganic filler CeO₂-ZrO₂-Al₂O₃(CZA) powder on the anticorrosive and mechanical properties of acrylic coatings, CZA powder samples were synthesized by drying and calcination using the co-precipitation method. The obtained CZA powder was fully dispersed in acrylic resin with commonly used dispersants, defoamers and other additives available in the market, and the acrylic anticorrosive coatings with different mass fractions were prepared on treated iron plates by the scraping method. Meanwhile, the XRD, SEM and EDS methods were used to analyze the physical phase of the CZA powder samples, and the mechanical property tests and electrochemical anticorrosion property tests were utilized to evaluate the characteristics of the coatings, such as adhesion, hardness, roughness, bending performance, wear resistance, tensile strength, elongation at break and anticorrosion performance. Results showed that the as-prepared CZA powders were solid solutions and showed a tetrahedral structure. After adding CZA powder, the hardness of the coating increased from HB to 1H, the bending properties were all 1T, wear resistance was improved, and adhesion was all grade 1. CZA increased the anticorrosive properties of the coatings compared to acrylic anticorrosive coatings without CZA addition, and the best anticorrosive properties of the coatings were obtained when the mass fraction of filler addition was 10%. Overall, the acrylic anticorrosive coating had certain anticorrosive properties and could effectively prevent the corrosion of corrosive media on the material, which presented certain application prospects in the field of anti-corrosion in the future.

Key words： CZA powder; acrylic resin; coating; roughness; anti-corrosion properties
