Problems solved by technology

However, after this kind of anti-rust liquid is applied on the metal surface, the liquid film is easy to flow, and after the water volatilizes, a layer of white frost will be formed on the metal surface, losing the proper anti-rust effect, and the anti-rust performance is not as good as that of anti-rust oil. Effect
Moreover, the traditional water-based anti-rust liquid mostly contains nitrite, dichromate and other components. As we all know, nitrite is a carcinogen and is harmful to the health of the operator. Heavy metals, which are harmful to the environment and also affect the performance and quality of metals

Abstract

The invention discloses a micro emulsion type water-based metal anti-rusting liquid which is prepared from the following raw materials in percentage by mass: 0-10% of anti-rusting agent, 3-20% of base oil, 0-10% of surfactant, 5-20% of corrosion inhibitor, 0.5-1.5% of stabilizing agent, 0-1% of thickening agent, 0-5% of pH adjusting agent and the balance of deionized water. By adopting the anti-rusting liquid, both the defect that an existing anti-rusting liquid such as an oil-based anti-rusting liquid is large in elimination difficulty and not easy to decompose and the defect that the anti-rusting effect of an existing water-based anti-rusting liquid cannot meet the anti-rusting effect of an oil-based anti-rusting liquid are solved, and the advantages of two anti-rusting liquids are integrated, so that the anti-rusting liquid disclosed by the invention has good functions of lubrication, cooling, anti-rusting and the like, and meanwhile the requirements of environmental-friendliness, economy and high efficiency are met.

Description

technical field [0001] The invention relates to a metal antirust liquid, in particular to a microemulsion water-based metal antirust liquid. Background technique [0002] Metal corrosion is a problem often encountered in production. Metal rust not only damages the shape, color and mechanical properties of the metal workpiece itself, but also reduces the quality of the product, and even makes the product scrapped if it is particularly serious. In 2011 my country's GDP is 7.43 trillion U.S. dollars, and the economic loss caused by corrosion is as high as 220 to 370 billion U.S. dollars, accounting for about 3% to 5% of the national GDP. In order to slow down the corrosion of steel and minimize the loss caused by corrosion, people have taken many anti-corrosion measures, among which the use of anti-rust liquid is the most widely used and most effective one. [0003] Antirust Fluid is a super efficient synthetic penetrant that forms a thin film on metal surfaces to prevent rusti...
