The invention discloses a galvanized layer chromium-free passivating agent and a preparation method thereof. The passivating agent comprises the following components: sodium hydrogen sulfate, sodium tripolyphosphate, sodium alkyl benzene sulfonate, ammonium acetate, alumina, starch, thiourea, dicyclohexylamine nitrite, methyl cellulose, methylparaben, ethylene glycol monostearate and deionized water. The preparation method includes: adding sodium hydrogen sulfate, sodium tripolyphosphate, sodium alkyl benzene sulfonate, ammonium acetate, and thiourea into the deionized water, stirring and mixing the materials evenly at room temperature to obtain a mixed solution 1; adding alumina, starch, dicyclohexylamine nitrite, methyl cellulose, methylparaben and ethylene glycol monostearate into ethanol absolute, subjecting ethanol to heating refluxing, and conducting filtering to obtain a solid mixture, and performing drying to obtain an intermediate 1; then adding the intermediate 1 into the mixed solution 1 obtained in step two, and conducting stirring mixing under a vacuum heating condition, thus obtaining the galvanized layer chromium-free passivating agent. The galvanized layer chromium-free passivating agent provided by the invention has excellent corrosion resistance.

The invention provides a gaseous phase rust-resisting material for rust-resisting seal of a tire bead steel wire. The rust-resisting material comprises a loading layer, a volatile layer, a permeation layer and a protective layer; and the invention further provides a preparation method of the gaseous phase rust-resisting material for the rust-resisting seal of the tire bead steel wire. The method comprises a preparation step of the volatile layer; the volatile layer is a non-woven fabric layer; non-woven fabric is subjected to coating processing; an antirust agent solution is adopted as a coating agent; and the antirust agent solution is prepared from the following raw materials: dicyclohexylamine nitrite, polyethylene glycol and distilled water. According to a gaseous phase sustained-release material prepared by the invention, rust-resisting material damage caused in the process of use due to carrying the tire bead steel wire can be reduced by a large margin; the completeness of the rust-resisting material is improved to the maximum extent; the rust-resisting capacity and rust-resisting time are improved; and the acid and alkali resistant capacity, the anti-aging capacity and the heat resistant capability are improved.

The invention relates to a steel bar corrosion inhibitor which is composed of a compaction component and a corrosion inhibition component, wherein the compaction component is silicate mineral which accounts for 0.5-1.0 wt% of the cementing material in concrete; and the corrosion inhibition component is composed of 1-amino-8-naphthyl-3,6-disulfonic acid monosodium salt which accounts for 0.10-0.30 wt% of the cementing material in the concrete, thiocarbamide which accounts for 0.15-0.30 wt% of the cementing material in the concrete, nitrto bicyclohexylamine which accounts for 0.25-0.40 wt% of the cementing material in the concrete, and fly ash which accounts for 1.25-1.75 wt% of the cementing material in the concrete. The corrosion inhibitor has favorable adaptability with cement, can properly improve the properties of the concrete and decelerate the permeation of the corrosive medium into the concrete, and forms a compact chemical adsorption film on the surface of the steel bar to prevent the corrosive medium and oxygen in the concrete hole solution from directly contacting the steel bar, thereby preventing electrochemical corrosion and further preventing the corrosion effect on the steel bar.
