Formula and preparation of novel environmentally-friendly water-soluble rust inhibitor

Abstract

The invention discloses a formula and preparation of a novel environmentally-friendly water-soluble rust inhibitor, wherein the components of the formula comprise triethanolamine, dodecenylsuccinic acid, sodium edetate and deionized water. The preparation steps comprise: adding sodium edetate to deionized water, and carrying out stirring dissolving to obtain a sodium edetate liquid; mixing triethanolamine and dodecenyl succinic acid, and stirring uniformly to achieve a viscous state so as to obtain a first mixed solution; continuously adding the sodium edetate liquid to the first mixed solution while stirring until the solution is transparent to obtain a second mixed solution; and standing the second mixed solution until the solution is layered, and removing the upper layer oil liquid to obtain the novel environmentally-friendly water-soluble rust inhibitor. According to the present invention, the novel environmentally-friendly water-soluble rust inhibitor has wide uses, can be directly used for the rust prevention of ferrous metal test members, can be used for blending cutting fluids, has good rust resistance, and further has characteristics of no harm to the human body and no environment pollution.

Description

technical field [0001] The invention relates to the formulation and preparation of a novel environment-friendly water-soluble antirust agent. Background technique [0002] Metal processing parts are prone to rust during production, processing and transportation, which requires the use of anti-rust oil to form a thin film on the metal surface to prevent metal corrosion. [0003] Anti-rust agent is a super-efficient synthetic penetrating agent, which can penetrate into rust, corrosion, and oil stains to easily remove rust and corrosion on screws and bolts. Corrosion, metal protection and other properties. And it can form and store a layer of lubricating film on the surface of the component, which can inhibit the corrosion caused by moisture and many other chemical components. It is a kind of surfactant that can make a liquid penetrate into a certain solid quickly and evenly, and has a wide range of uses in the printing and dyeing industry. [0004] After the "Sixth Five-Yea...

Problems solved by technology

[0005] Although the anti-rust technology continues to develop, the anti-corrosion effect of most domestic anti-rust agents is not ideal, and with the increasingly stringent requirements of environmental protection regulations and the improvement of people's awareness of environmental protection, the composition and use of anti-rust agents have also been raised. Therefore, the use of anti-rust materials that meet environmental protection requirements and the development of biodegradable anti-rust products have gradually become the mainstream of the development of anti-rust agents.
