摘　　要：以生物质材料糠醛衍生物为主体,采用葡萄糖酸钠、苯甲酸钠复配制得生物基防锈剂。通过静态失重、接触角、扫描电镜、防锈性能测试以及涂层附着力和耐盐雾性等测试方法对其防锈性能,以及与EP-01环氧富锌底漆和MC-WEP-3水性环氧富锌底漆的配套使用性能进行了研究。研究结果表明,HMF在90℃条件下,其缓蚀性能基本丧失;30℃条件下,在1 mol/L HCl溶液中,300 ppm HMF对Q235的缓蚀率达到69.4%;添加2%防锈剂的样板在水除锈工艺后24 h内表面无明显返锈,且对后续溶剂型和水性环氧富锌底漆的附着力、耐盐雾性无明显影响。A bio-based rust inhibitor is prepared by using biomass material furfural derivatives as the matrix substance in addition to compounding of sodium gluconate and sodium benzoate,.The rust resistance of the bio-based rust inhibitor is investigated via a series of tests including static weight loss,contact angle,scanning electron microscopy,rust resistance testing,coating adhesion and salt spray resistance,etc.And its compatibility with EP-01 epoxy zinc rich primer and MCWEP-3 waterborne epoxy zinc rich primer is also studied.The results indicate that the corrosion inhibition performance of HMF is basically lost at 90℃.the corrosion inhibition rate of 300 ppm HMF on Q235 at 30℃in a 1mol/L HCl solution can reach up to 69.4%.The addition of 2%rust inhibitor in water rust-removing process enables no obvious rust on the surface of the sample within 24 hours,and has no impact on the adhesion and salt spray resistance of subsequent solventbased or waterborne epoxy zinc rich primers.
