Dampness-heat-resistant water-based antirust agent and preparation method thereof

Abstract

The invention discloses a dampness-heat-resistant water-based antirust agent. The dampness-heat-resistant water-based antirust agent is characterized by being prepared from the following raw materials in parts by weight: 4-6 parts of waterborne polyurethane resin, 0.5-1 part of polydimethylsiloxane, 1-2 parts of sodium N-acyl glutamate, 0.2-0.4 part of octadecyl dihydroxyethyl amine oxide, 1-2 parts of sodium potassium tartrate tetrahydrate, 0.2-0.4 part of terpinyl acetate, 2-4 parts of triethanolamine borate, 0.5-1 parts of poloxamer, 1-2 parts of mannitol, 1-2 part of flaxseed gum, 0.5-1 part of sucrose fatty acid ester, 6-8 parts of a modifying auxiliary and 30-40 parts of water. A film formed by the dampness-heat-resistant water-based antirust agent on a metal surface has good dampness-heat resistance, good corrosion resistance, a good antifouling and antistatic effect and good resistance, and corrosion can be effectively prevented.

Description

Technical field [0001] The invention relates to the field of metal treatment, and in particular to a moisture-resistant hot water-based rust inhibitor and a preparation method thereof. Background technique [0002] Metal workpieces are prone to rust during production, processing and transportation. Once rusted, it will have a negative impact on the appearance and performance of the finished product. Severe rust may even cause the steel to be scrapped. The rust of steel causes huge losses to the national economy, so it is necessary to use anti-rust agents to protect metals. Rust inhibitors work by forming a thin film on the surface of the metal to prevent it from rusting. Most of the commonly used anti-rust agents are oil-based, which use a large amount of organic solvents in the process of production and use, causing pollution to the environment. Therefore, the research on water-based anti-rust agents is of great significance. [0003] Most of the traditional metal water-b...

Most of the commonly used antirust agents are oily, and a large amount of organic solvents are used in the process of production and use, causing pollution to the environment. Therefore, the research on water-based antirust agents is of great significance

[0003] Most of the traditional metal water-based rust inhibitors contain nitrite, which has the advantages of low price, good effect, convenient use, and easy removal. However, because nitrite can be converted into carcinogens, its use and discharge have been strictly controlled. limit
