Water-soluble environment-friendly anti-rusting agent, and preparation method and application thereof

Abstract

The invention provides a water-soluble environment-friendly anti-rusting agent, and a preparation method and application thereof. The water-soluble environment-friendly anti-rusting agent comprises the following components in percentage by mass: 1.5 to 2 percent triethanolamine, 0.15 to 0.2 percent of sodium benzoate, 1.5 to 2 percent of sodium tetraborate, 0.5 to 1 percent of sodium carbonate, 1.5 to 2 percent of sodium gluconate and the balance of water. The anti-rusting agent is prepared by mixing and uniformly stirring the components, and the pH value of the anti-rusting agent is adjusted to be 8 to 10 by adjusting the amount of each component in a mixing and stirring process. The water-soluble environment-friendly anti-rusting agent can be used for the anti-rusting protection of ferrous metal such as cast iron and steel and nonferrous metal such as copper, aluminum and magnesium, is free of environmental pollution, harmless to a human body, low in cost and easy to prepare, has superior anti-rusting effects, and is applied to the anti-rusting of various kinds of metal, and the required components are simple and easily available.

Description

technical field [0001] The invention belongs to the field of antirust agent preparation, and in particular relates to a water-soluble environment-friendly antirust agent and its preparation method and application. Background technique [0002] At present, most of the short-term rust prevention (such as inter-process rust prevention) of metal or its products uses water-based rust inhibitors, but most water-based rust inhibitors have serious environmental pollution and difficult post-processing, which brings problems to the use. Many inconveniences, such as the water-based rust inhibitor represented by sodium nitrite, is an inorganic salt metal corrosion inhibitor, and sodium nitrate is all the rage because of its good rust resistance, low price, and convenient use. The reaction of organic amines can generate carcinogenic nitrosoamines and seriously endanger the physical and mental health of workers. Therefore, the use and discharge of sodium nitrite are strictly restricted. ...
