Environment-friendly, long-acting and high-performance anti-rusting cleaning agent for metal and preparation method thereof

Abstract

The invention discloses an environmentally friendly, long-lasting, high-performance anti-rust cleaning agent for metals, which includes the following raw materials by weight: 8-12 parts of phosphate, 7-9 parts of borate, 1-2 parts of modified diatomite, 0.5-1.5 parts of triethanolamine, 1-3 parts of sodium salt, 0.5-0.9 parts of surfactant, 2-3 parts of polyvinyl alcohol, 1-3 parts of liquefied paraffin, 1-2 parts of silicone oil, diethylene glycol monobutyl 3-5 parts of ether, 2-4 parts of sorbitan monooleate, 9-13 parts of vegetable oil, 10-14 parts of propylene glycol, and 90-110 parts of water. The invention has excellent contact anti-rust performance and good gas-phase anti-rust effect. It is suitable for salt spray environment, hot and humid environment or occasions requiring long-term anti-rust. It can be used for carbon steel, cast iron, alloy steel, galvanized sheet, copper and aluminum , low-corrosion-resistant stainless steel and other metals for long-term and ultra-long-term rust prevention, as well as storage and rust prevention in harsh environments such as ocean transportation, humidity and heat.

Description

technical field [0001] The invention relates to the field of environmental protection antirust technology, in particular to an environmental protection long-acting high-performance antirust cleaning agent for metals and a preparation method thereof. Background technique [0002] With the development of the country's economy, the industry has developed in great strides, and most industrial products use metal materials. During the manufacturing process, it is inevitable to remove rust products and carry out rust prevention between processes; It may be corroded by oxygen or acid-base medium in the environment. To prevent rust, the rust that has already occurred must be derusted and then rust-proofed. In order to avoid rust and reduce losses, people have adopted various methods. One of the most common methods of protection is to use antirust agents to protect metal products. Antirust agent is composed of adding one or more antirust additives (also known as oil-soluble corrosion...

Problems solved by technology

Traditional water-based anti-rust agents generally use carcinogenic and teratogenic ingredients such as nitrite and dichromate for anti-rust treatment, which has a great negative impact on the health of workers and environmental pollution
