Abstract

The invention discloses an environment-friendly dust and oil removal agent which is prepared from the following raw materials in parts by weight: 500 parts of water, 300-400 parts of concentrated hydrochloric acid, 30-50 parts of ammonium chloride, 0.2-0.6 part of trioctylamine, 0.3-1.0 part of hexamethylenetetramine, 0.5-1.0 part of triethanolamine, 0.3-0.8 part of OP-10, 0.3-0.8 part of tween-80 and 0.1-0.5 part of benzotriazole. During use, the raw materials are just mixed at a constant temperature. The environment-friendly dust and oil removal agent disclosed by the invention has the advantages that the environment-friendly dust and oil removal agent is simple in formulation, simple in operation and wide in application range, and the main reagent concentrated hydrochloric acid is low in cost and easy to obtain. The use levels of a corrosion inhibitor, an acid mist inhibitor and an oil remover are fewer. The environment-friendly dust and oil removal agent is less in environmental pollution, and both the dust removal rate and the oil removal rate within a hour at room temperature reach 99.8%.

Description

technical field [0001] The invention relates to a rust-removing and oil-removing agent, in particular to an environment-friendly rust-removing and oil-removing agent. technical background [0002] Steel is the most widely used material in the development of the national economy, and it still dominates as a structural material. Iron and steel materials are smelted and processed from iron ore many times to produce steel products that meet the development needs of various industries. According to statistics, the overall industrial chain of the iron and steel industry accounts for about 8.8% of China's total GDP. In 2008, China's crude steel output reached 500 million tons, accounting for 38% of the global output, and its consumption was 450 million tons. The direct export was equivalent to 60 million tons of crude steel, accounting for 15% of the world's steel trade. However, the loss of steel materials due to corrosion has always been serious during use. [0003] Since ente...
