摘　　要：本研究以聚乙烯醇(热溶型,固含量20%,组分a)为成膜物质,选取硼酸为交联剂(组分b),改变其用量(质量分数0.5%~2.5%),制备硼酸改性聚乙烯醇双组份水性涂料,研究了硼酸用量对涂料性能的影响,实验结果显示,硼酸用量为1.5%时,聚乙烯醇双组份水性涂料漆膜的附着力达到0级、铅笔硬度为9H;当硼酸用量为1.5%,在聚乙烯醇双组分水性涂料中,加入不同质量分数蒙脱土(0.05%~5.0%),研究蒙脱土用量对涂料性能的影响,实验结果显示,蒙脱土用量为0.05%时,漆膜的耐腐蚀性能得到进一步提高。With polyvinyl alcohol as the film-forming substance,this study selects boric acid as the crosslinker to prepare boric acid modified polyvinyl alcohol two-component waterborne coatings,and the effect of boric acid content on coating film performance is discussed.The experimental results show that the polyvinyl alcohol two-component waterborne coatings by using 1.5% mass fraction of boric acid exhibits good adhesion and the pencil hardness of the coating flm reaches 9H.Different mass fraction of montmorillonite is added to investigate the performance of boric acid modified polyvinyl alcohol two-component waterborne coatings,the results show that the corrosion resistance of the coating film is further improved when the dosage of montmorillonite is 0.05%.
