Abstract
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
The present invention relates to a kind of prescription of passivator, especially a kind of prescription that does not contain carcinogenic hot dip process organic acid chrome-free tanning agent.
Background technology
The loss that the natural disasteies such as earthquake, typhoon, ice and snow are brought is direct and obvious, and the corrosion of steel member then is the carrying out of " quiet silence ", but the loss that the corrosion of steel member brings will be far longer than the financial loss that these natural disasteies cause.Calculate the marine corrosion method according to the current international practice, the national financial loss that therefore causes was above 14,000 hundred million yuans in 2010, this numeral had then surpassed 16,000 hundred million yuans in 2011, change vivider saying into, national 1 year because of corrosion loss or the iron and steel of falling that becomes rusty, almost equal 1 year Iron and Steel Production total amount of 3 species abundance in Baosteel in Shanghais, the whole world then more very, thereby the anticorrosion important topic that becomes against corrosion.
Answer the requirement of galvanizing corrosion resistance, generally behind galvanizing, carry out chromic acid passivation and process; Because chromic acid belongs to carcinogenic heavy metal, unfriendly to environment, thereby research and develop a kind of Technology harmless, environmentally friendly, that passivation effect is good and substitute chromic acid passivation and become the important R﹠D direction of zinc-plated industry.
This project is by the environment amenable organic acid chrome-free tanning agent of development, improve the environmentally harmful passivator that contains trivalent chromium, sexavalent chrome carcinogenic substance of present domestic current, the direction that meets the environmental protection policy development of country, this project is underwritten in simultaneously development, for the update of domestic Passivated Hot Galvanizing Technology, tool is of great significance.
Summary of the invention
The objective of the invention is provides a kind of prescription that does not contain carcinogenic hot dip process organic acid chrome-free tanning agent for the deficiency that solves above-mentioned technology.
In order to achieve the above object, the prescription of a kind of hot dip process organic acid chrome-free tanning agent that the present invention is designed, it comprises organic acid, many sodium alkyl sulfates, N methyne tetramine, nontoxic water-soluble acrylic ester, does not contain the inhibiter molybdate of chromium, and the ratio of described above material is followed successively by 2:1:1:1:1.5.
The prescription of the resulting hot dip process organic acid of the present invention chrome-free tanning agent, adopt environment amenable organic acid passivator, abandoned existing harmfully and have the trivalent chromium of carcinogenic substance, chromic passivator to environment, reduced the pollution of hot-dip galvanizing technique to environment; The pH value of hot dip process organic acid chrome-free tanning agent is 6.5～7.0, has really realized low sour Chrome-free; The characteristics that the hot dip process organic acid chrome-free tanning agent that the present invention obtains has in 100 ℃ of following temperature is non-volatile, do not decompose, thermal stability is good.
