lubricative water based metal surface treatment agent and metal surface treatment method using the same
2015Co-Authors: Guo JingguoAbstract:The invention relates to a lubricating water-based metal surface treatment agent and a metal surface treatment method using the same. The lubricating water-based metal surface treatment agent comprises a water-based chromium-free composition, a water-soluble or water-dispersible organic resin and a wax additive. The water-based chromium-free composition comprises a water-soluble Zirconium Compound, a silicon Compound, a fluorine containing Compound, a phosphoric acid Compound and a metal Compound. The ratio of a solid component of the organic resin to the overall solid component is between 0.01 to 0.9. The ration of a solid component of the wax additive to the overall solid component is between 0.005 to 0.03. Thereby a metal material having the lubricating water-based metal surface treatment agent can have good corrosion resistance, alkali washable performance, lubricity and wear resistance.
