Environment-friendly metal oil/rust-removing anti-rust solution

Abstract

The invention discloses an environment-friendly metal oil / rust-removing anti-rust solution. The environment-friendly metal oil / rust-removing anti-rust solution is prepared from the following raw materials in parts by weight: 4-5 parts of benzoic acid, 3-5 parts of polypropylene, 1-2 parts of fatty alcohol-polyoxyethylene ether, 3-5 parts of cocamidopropyl betaine, 1-3 parts of coconut fatty acid diethanolamide, 2-3 parts of cetyl trimethyl ammonium bromide, 3-5 parts of tetraethylammonium bromide, 2-3 parts of tert-butyldiphenylsilane, 1-3 parts of di-o-tolyl-thiourea, 1-2 parts of ethylene diamine tetraacetic acid, 1-2 parts of xylenol orange, 2-3 parts of aluminum dihydrogen phosphate, 3-4 parts of sodium hexametaphosphate, 2-3 parts of acetic acid, 50-55 parts of phosphoric acid, 3-5 parts of sodium lignin sulfonate, 2-3 parts of disodium methylene dinaphthalenesulfonate and 50-70 parts of purified water. The environment-friendly metal oil / rust-removing anti-rust solution is multifunctional, and is not only applicable to line production to perform oil removal, rust removal, phosphatization, passivation and rust prevention on metal surfaces at one time, and is harmless to the human body and free from pollution to the environment.

Description

technical field [0001] The invention relates to the technical field of an oil-removing, rust-removing and anti-rust liquid, in particular to an environment-friendly metal oil-removing, rust-removing, and anti-rust liquid. Background technique [0002] At present, the oil and rust removal of metal surface treatment in the prior art basically uses artificial, physical and chemical methods. Manual oil and rust removal is labor-intensive, low in efficiency and cannot completely remove oil and rust, leaving a large number of blank spots , affects product quality, and produces a large amount of dust, pollutes the environment, and endangers the health of workers; physical rust removal, mainly ultrasonic degreasing and rust removal, is not widely used due to large investment; chemical degreasing and rust removal on metal surfaces The most common and economical method is to deal with it. The traditional oil removal is treated with strong alkali sodium hydroxide and tetrachlorethylene...
