A kind of water-based environmental protection rust inhibitor for steel parts and its preparation method and application

Abstract

The invention provides a water-based environmental protection rust inhibitor for steel parts, and a preparation method and application of the water-based environmental protection rust inhibitor. The rust inhibitor is prepared from polyvinyl butyral and a bis-silane phenolic compound which are used as film-forming agents, a corrosion inhibitor A, a corrosion inhibitor B, zinc phosphate used as anti-rust pigment, a dispersing agent, a complexing agent, modification additives, other additives, and a solvent formed by ethanol and deionized water. An anti-rust film formed by the rust inhibitor is good in mechanical properties, high in hardness and compactness, wear-resistant and scratch-resistant, and high in impact resistance; the water-based environmental protection rust inhibitor is good in compatibility with the anti-rust pigment, environmentally-friendly and free from pollution; the rust inhibitor is good in rust prevention effect, can be cured at the room temperature and is uniform in film formation; the rust inhibitor is high in binding force with a base material; the rust inhibitor is good in high-temperature stability and low-temperature stability, and enables a whole rust removal system to be stable.

Description

technical field [0001] The invention relates to the field of metal antirust, in particular to the field of water-based environment-friendly antirust agent for steel parts. Background technique [0002] Metal corrosion is a common but unavoidable phenomenon in real society. For example, machinery, equipment, and buildings made of various metals will rust due to being exposed to the air for a long time. When the air is filled with a large amount of water vapor and salt spray, The corrosion phenomenon is even more significant, such as aircraft and ships. In addition, the corrosion of metals has a huge impact on the national economy. In 2012, the economic loss caused by corrosion in my country was 800 billion yuan. The results of the corrosion loss survey in the United States in 2010 showed: Corrosion losses cost approximately $476 billion, which is roughly 1.2 percent of the U.S. gross national product. Moreover, corrosion will also cause irreversible damage and loss to the shap...

Problems solved by technology

Moreover, corrosion will also cause irreversible damage and loss to the shape, luster and mechanical properties of the metal, and some may even directly scrap the product, resulting in a waste of resources. Therefore, it is very necessary for the antirust treatment of metal parts
