Rust inhibitor for industrial machinery and preparation method thereof

Abstract

The invention provides a rust inhibitor for industrial machinery and a preparation method thereof. The rust inhibitor for industrial machinery is composed of the following components in parts by mass: 1-3 parts of triethanolamine oleate, 3-4 parts of inorganic additive, 1-3 parts of sodium borate, 0.5-2 parts of water-based nano bentonite, 1-3 parts of epoxy acid zinc salt, 2-4 parts of fatty alcohol polyoxyethylene ether, 1-4 parts of dialkenyl succinimide, 1.5-4 parts of sodium N-lauroyl sarcosinate, 6-9 parts of n-butanol and 60-80 parts of water. The preparation method comprises the following steps: mixing, heating, stirring, ultrasonic treatment and the like. The prepared rust inhibitor has excellent rust resistance under the conditions of acids, alkalis, salt mist and the like, has the advantages of high safety, environment friendliness and uniform components, and can effectively ensure the flatness and smoothness of the metal surface; and the effective life is up to two years or above.

Description

technical field [0001] The invention relates to the technical field of metal surface treatment, in particular to an antirust agent for industrial machinery and a preparation method thereof. Background technique [0002] Industrial machinery is mostly made of metal, and metal will react chemically or electrochemically with oxygen, water and other substances under certain conditions in the atmosphere to cause corrosion, which not only affects the appearance of the material, but even directly affects its service life, causing huge damage. Economic losses. Therefore, in the prior art, antirust agents are often applied to metal surfaces for protective treatment, but most of the early antirust agents contain highly toxic nitrite, which will not only cause pollution, but also form a layer after being applied to the metal surface. Hoarfrost loses its proper anti-rust effect. In addition, most of the antirust agents widely used in the industry contain phosphorus-containing substanc...

Problems solved by technology

[0002] Industrial machinery is mostly made of metal, and metal will react chemically or electrochemically with oxygen, water and other substances under certain conditions in the atmosphere to cause corrosion, which not only affects the appearance of the material, but even directly affects its service life, causing huge damage. Economic losses

Therefore, in the prior art, antirust agents are often applied to metal surfaces for protective treatment, but most of the early antirust agents contain highly toxic nitrite, which will not only cause pollution, but also form a layer after being applied to the metal surface. Hoarfrost, lose the proper anti-rust effect

In addition, most of the antirust agents widely used in the industry contain phosphorus-containing substances such as phosphates, which will cause eutrophication when discharged into water bodies, while antirust oils contain heavy metals and carcinogens, which have caused great harm to the environment and people's health. the harm of
