Preparation process of corrosion-resistant hot-dip galvanizing electrostatic spraying guardrail
The invention relates to the technical field of hot galvanizing spraying processes, and discloses a preparation process of an anti-corrosion hot galvanizing electrostatic spraying guardrail, the outer surface of a guardrail main body is sprayed with an anti-corrosion coating, and the preparation process of the anti-corrosion coating sprayed on the guardrail comprises the following steps: S1, preparing a base material; s2, base material oil diffusion; s3, cutting the base material; s4, punching the base material; s5, base material degreasing; s6, phosphating the base material; s7, spraying and washing the base material; s8, drying the base material; s9, primary spraying of the base material; s10, primary curing of the base material; s11, secondary spraying of the base material; s12, carrying out secondary curing on the base material; s13, spraying the base material for the third time; s14, curing the base material for the third time; and S15, packaging and conveying. And S16, the guardrail is assembled, a layer of compact phosphating film is formed on the surface of the workpiece, formation of microbatteries on the surface of the metal workpiece is inhibited, corrosion of a coating film is effectively prevented, the adhesive force between a base body and a coating or between other organic finishing layers is improved, and the corrosion resistance and the adhesive performance of the preparation technology of the corrosion-resistant hot-dip galvanizing electrostatic spraying guardrail are improved.
本发明涉及热镀锌喷涂工艺技术领域，且公开了一种耐腐蚀热镀锌静电喷涂护栏制备工艺，所述护栏主体的外表面均喷涂有防腐涂料，所述护栏喷涂防腐涂料的制备工艺步骤由S1‑S16组合而成，S1基材准备；S2基材漫油；S3基材切割；S4基材冲孔；S5基材脱脂；S6基材磷化；S7基材喷洗；S8基材烘干；S9基材一次喷涂；S10基材一次固化；S11基材二次喷涂；S12基材二次固化；S13基材三次喷涂；S14基材三次固化；S15包装运送；S16组装护栏，工件表面形成一层致密的磷化膜，抑制金属工件表面微电池的形成，有效阻止涂膜的腐蚀，提高基体与涂层间或其他有机精饰层间的附着力，耐腐蚀热镀锌静电喷涂护栏制备工艺的耐腐蚀性与附着性能得到提高。
