Problems solved by technology

[0002] Most industrial products use metal materials. During the manufacturing process, it is inevitable to remove rust products and prevent rust between processes; after the products are manufactured, they may be exposed to oxygen or acid-base media in the environment during delivery, storage, and use. For the corrosion of the corrosion, it is necessary to carry out rust prevention. For the rust that has already occurred, it is necessary to carry out rust removal and then anti-rust. Traditional water-based anti-rust agents generally use carcinogenic and teratogenic ingredients such as nitrates, nitrites, and dichromates. Anti-rust treatment has a great negative impact on workers' health and environmental pollution

Abstract

The invention provides an environment-friendly rust-removing anti-rust agent. The agent consists of the following raw materials, by weight: 5%-20% of diethylene glycol monobutyl ether, 10-15% of KOH, 5-10% of oxalic acid, 5-10% of gluconic acid, 5-10% of phosphate, 2-5% of potassium tetraborate and the balance of deionized water. The environment-friendly rust-removing anti-rust agent provided by the invention has good rust-removing and anti-rust performance, and is healthful and environment-friendly. The environment-friendly rust-removing anti-rust agent can be diluted with 0-50 times of water and used for rust removal and rust prevention under different processing processes and different conditions.
