本发明所要解决的技术问题采用以下技术方案来实现：
水溶性酚醛树脂防锈涂料的合成工艺，其特征在于：包括以下工艺步骤，
a.选取一反应烧杯，并且称取32-33g的亚麻油与9-10g顺丁烯二酸酐放入反应烧杯中，将温度升至180-200℃，恒温反应2h。
b.再次称取3-4g的酚醛树脂投放至步骤a中的反应烧杯中，将温度升至220-300℃。
c.测定上述步骤b中的酸值，当酸值达到60-80mg/KOH/g时，将反应物温度降至90-100℃后，向内部加入8-12ml的正丁醇，继续降温直至温度为≤60℃。
d.将上述步骤c中的反应溶液中采用氨水将PH值调至7.5-8.5。
e.对步骤d中的中和后溶液进行搅拌并且同时加入水进行稀释直至固含量为45％-55％，搅拌均匀后即得到水溶性树脂基料备用。
f.选取一研钵，称取亚铃酸钙14-16g、磷酸锌8-12g、硫酸钡1-3g、滑石粉1-3g和轻质碳酸钙1-3g，全部放入研钵中进行研磨均匀。
g.选用的砂磨机将上述步骤e中制的的水溶性树脂基料和步骤f中研磨后的混合物加入其中进行砂磨。
h.当上述步骤g中砂磨后颗粒细度≤50um时，向内部加入0.8-0.9g的环烷酸钴，再向内部加入14-16ml的去离子水将黏度调和后即得到水溶性酚醛树脂防锈涂料成品。
本发明的有益效果是：本发明制备方便简单，环保无污染，原料易得，设备投资少，品质纯正，便于操作，制备的水溶性酚醛树脂防锈涂料使用效果好，安全可靠。
