Embodiment 1

[0014] Based on the total weight of the antirust agent as 100%, according to the following proportions: 1.5% sodium molybdate, 4% sodium silicate, 0.5% hexamethylenetetramine, 0.05% non-ionic surface active agent, prepare 100kg antirust agent Rust agent. The prepared antirust agent is mixed with water at a ratio of 1:5 to make an antirust solution. After phosphating and washing the workpiece, immerse it in the antirust solution for 3 minutes and then take it out. The workpiece has not been rusted after being stored on site for 6 months.

Embodiment 2

[0016] Based on the total weight of the antirust agent as 100%, according to the following proportions: 0.5% sodium molybdate, 2% sodium silicate, 3% hexamethylenetetramine, 0.3% non-ionic surface active agent, prepare 100kg antirust agent Rust agent. The prepared antirust agent is mixed with water at a ratio of 1:8 to make an antirust solution. After phosphating and washing the workpiece, immerse it in the antirust solution for 15 minutes and take it out. The workpiece has not been rusted after being stored on site for 6 months.

Embodiment 3

[0018] Based on the total weight of the antirust agent as 100%, according to the following proportions: 1.0% sodium molybdate, 0.2% sodium silicate, 1.5% hexamethylenetetramine, 0.5% non-ionic surface active agent, prepare 100kg antirust agent Rust agent. The prepared antirust agent is mixed with water at a ratio of 1:10 to make an antirust solution. After phosphating and washing the workpiece, immerse it in the antirust solution for 30 minutes and then take it out. The workpiece has not been rusted after being stored on site for 6 months.

Abstract

The invention provides an antirusting agent, comprising 0.5 to 1.5 percent of sodium molybdate, 0.2 to 4 percent of sodium silicate, 0.5 to 3 percent of hexamethylenetetramine, and 0.05 to 0.5 percent of non-ionic surface active agent peregal, in terms of gross weight of the antirusting agent as 100 percent. The invention also provides a method for applying the antirusting agent. During use, the antirusting agent is mixed with water according to proportion of 1:5-1:10 to prepare antirusting solution; and a work piece is dipped in the antirusting solution for 2 to 30 minutes after phosphating and washing. The antirusting agent can improve the corrosion resistance of the metal surface and improve the performance of humidity isolation and air isolation of a protective layer while ensuring the performance of the original phosphate coating. The antirusting agent can not cause acid mist which pollutes environment, does not contain nitrite, bichromate and other toxic and polluting substances, can not burn skin during use, does not stimulate or damage human body, is safe and reliable, and is easy for operation.

Description

technical field [0001] The invention belongs to the field of metal antirust, and in particular relates to an antirust agent and a using method thereof. Background technique [0002] Iron and steel materials are widely used in various industries, but their losses due to corrosion are astonishing. At present, phosphating treatment is generally used for steel, and a certain phosphating film is formed on the surface. After phosphating treatment, its excellent physical and mechanical properties such as strength, hardness, elasticity, magnetism, ductility, etc. remain unchanged, while the surface of the treated iron and steel parts, due to the formation of a uniform and dense phosphating film, its friction resistance, The anti-stick performance is greatly improved. At the same time, the phosphating process is easy to operate and low in cost, so it is widely used in steel surface treatment. However, in actual production and use, since the steel cannot be used in time after phosp...
