Problems solved by technology

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

Abstract

The invention discloses a water-based antirust agent containing green tea extracts. The water-based antirust agent is prepared from the following raw materials in parts by weight: 1-2 parts of polyepoxysuccinic acid, 1-2 parts of polymaleic anhydride, 0.1-0.2 part of ascorbyl phosphate, 0.5-1 part of green tea extracts, 1-2 parts of borax, 1-2 parts of sodium gluconate, 1-2 parts of alums, 1-2 parts of aluminum chloride, 3-5 parts of sodium carboxymethylcellulose, 2-4 parts of carboxymethyl chitosan, 2-4 parts of gamma-poly(sodium glutamate), 1-2 parts of sodium lauroyl sarcosine, 6-8 parts of a modified additive and 30-40 parts of water. The antirust agent disclosed by the invention has the characteristics of good antirust effect and lasting efficacy, is safe and non-toxic, and is suitable to be used in family environments.

Description

technical field [0001] The invention relates to the field of metal treatment, in particular to a water-based antirust agent containing green tea extract 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. Serious corrosion may even cause the steel to be scrapped. The rusting of steel has caused huge losses to the national economy, so it is necessary to use rust inhibitors to protect metals. Rust inhibitors work by preventing the metal from rusting by forming a thin film on the metal surface. 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 ...
