The invention relates to a formula of a passivator, and in particular relates to a formula of a hot dip organic low acid chromate-free passivator without carcinogenic substances. The invention aims to solve the deficiencies in the prior art. The formula comprises organic acid, sodium polyalkyl sulfate, N methenyl tetramine, nontoxic water soluble acrylic ester, and chromate-free corrosion inhibitor molybdate. The hot dip organic low acid chromate-free passivator does not contain trivalent chromium and hexavalent chromium with carcinogenic substances, so that the environmental pollution due to a hot-dip galvanizing process is reduced. The passivator has the characteristics of no volatilization, no decomposition, and good thermal stability at a temperature below 100 DEG C.
Description
technical field [0001] The invention relates to a formula of a passivating agent, in particular to a formula of a non-carcinogenic organic acid chromium-free passivating agent for hot-dip plating. Background technique [0002] The losses caused by natural disasters such as earthquakes, typhoons, ice and snow are direct and obvious, while the corrosion of steel components is carried out "quietly", but the losses caused by the corrosion of steel components are far greater than these natural disasters. Economic losses caused by disasters. According to the internationally accepted method of calculating marine corrosion, the national economic losses caused by this in 2010 exceeded 1.4 trillion yuan, and in 2011 this figure exceeded 1.6 trillion yuan. The rusted steel is almost equal to the annual steel production of three Shanghai Baosteel, and even more so in the world, so corrosion resistance has become an important issue. [0003] In response to the requirements of hot-dip g...
