Problems solved by technology

At present, anti-rust and leak-detecting agents mostly use a large amount of xylene and ethanol as solvents, and sodium nitrite as an anti-rust agent. This type of raw material has hidden dangers such as high toxicity, flammability and explosion, and direct contact with the human body can easily cause cancer, neurasthenia syndrome, etc. disease

Abstract

The invention discloses an antirust leakage detection agent, which comprises, in parts by weight, 0.5 to 1 part of dicarboxylic acid, 2 to 4 parts of triethanolamine, 0.2 to 0.8 parts of sodium benzoate, 0.2 to 0.8 parts of benzotriazole, 0.5 to 2 parts of alkyl polyglucoside, 0.3 to 1 part of iso-tridecanol polyoxyethylene ether, 6 to 10 parts of ethylene glycol, 0.3 to 0.8 parts of hydroxyethylcellulose and water complemented to 100 parts. The action mechanism of the leakage detection agent is simple and scientific, anti-rust and foam effects achieve the best under cooperative effects of componenets, the solution thus has the characteristics of suitable viscosity, rich foam, antirust and good cleaning effects, the agent does not contain sodium nitrite or phosphorus and is thus safe, environmental-friendly and non-toxic, the source of raw materials is wide, acquisition is easy, the cost is low, and mass production is facilitated.

Description

technical field [0001] The invention belongs to the technical field of chemical products, and relates to a leak detection agent, in particular to a rust-proof leak detection agent and a preparation method thereof. The leak detection agent is a chemical leak detection agent which needs to judge the sealing performance of pipelines for transporting materials. Background technique [0002] Pipelines for transporting materials widely exist in the fields of electric power, electronics, metallurgy, chemical industry, petroleum, coal, mining, railway, transportation, medicine and scientific research institutions. It is very important to inspect and test the sealing performance of flange connections or welding joints between pipelines during production and use. The material of the transportation pipeline is mainly cast iron, carbon steel, alloy steel and other iron-based materials, and a small amount of non-ferrous metal materials are used. This requires that the leak detector not o...
