Aluminum alloy surface antiseptic protectant and antiseptic method

Abstract

The invention relates to an aluminum alloy surface antiseptic protectant and an antiseptic method; the aluminum alloy surface antiseptic protectant is made from 2-mercaptobenzothiazole MBT, 2-mercaptobenzimidazole MBI, 2-mercaptobenzoxazole MBO, benzotriazole BTA, polyacrylate, high-density polyethylene, a lubricant, and a surfactant; by weight, a ratio of the 2-mercaptobenzothiazole MBT, the 2-mercaptobenzimidazole MBI, the 2-mercaptobenzoxazole MBO and the benzotriazole BTA is 2:1:1:1.

Description

technical field [0001] The invention belongs to the field of anticorrosion agents, in particular to an aluminum alloy surface anticorrosion protectant and an anticorrosion method. Background technique [0002] Metal corrosion pervades all fields of national economy and national defense construction, and the harm is very serious. First, corrosion can cause significant direct or indirect economic losses. According to statistics from industrially developed countries [5] , The economic loss caused by corrosion accounts for about 1.5%-4.2% of the gross national economic product of the year. Secondly, metal corrosion, especially stress corrosion and corrosion fatigue, often cause catastrophic major accidents and endanger personal safety. Furthermore, corrosion not only consumes a large amount of metal, but also wastes a large amount of energy, and 10%-20% of metal is lost due to corrosion every year. In addition, in the industrial production of petroleum, chemical industry, an...

Problems solved by technology

However, corrosion inhibitor technology has obvious limitations. In the liquid medium where corrosion inhibitors are most widely used, corrosion inhibitors must have a certain solubility and must reach a certain concentration.

Traditional corrosion inhibitors have polluted the environment due to their high toxicity; at the same time, due to the small amount of corrosion inhibitors used, small changes in the outside world will have a greater impact on the system, which also brings new challenges to the study of corrosion inhibition mechanisms. These factors have limited the further development of corrosion inhibitors
