Abstract
The invention relates to an environment-friendly low-temperature efficient metal cleaner. The environment-friendly low-temperature efficient metal cleaner comprises nonionic surfactants I, nonionic surfactants II, anionic surfactants, fatty acid, defoaming agents, low-carbon alcohol and deionized water. Compared with other metal cleaners, the environment-friendly low-temperature efficient metal cleaner has the advantages that the environment-friendly low-temperature efficient metal cleaner is high in cleaning ability, and is good in degreasing ability for various metals even when used at low temperatures; all ingredients of the environment-friendly low-temperature efficient metal cleaner are safe and nontoxic, and the environment-friendly low-temperature efficient metal cleaner does not contain phosphate, nitrite and non-biodegradable substances; the pH (potential of hydrogen) of the environment-friendly low-temperature efficient metal cleaner is moderate, the environment-friendly low-temperature efficient metal cleaner does not corrode surfaces of the metals, is low-foam, is easy to rinse and good in stability, is excellent in antirust ability without antirust agents, can be applied to cleaning surfaces of parts of nonmetal materials, and has a broad application prospect, and a process for manufacturing the environment-friendly low-temperature efficient metal cleaner is simple.
Description
technical field [0001] The invention relates to the field of metal cleaning agents, an environmentally friendly low-temperature and high-efficiency water-based cleaning agent suitable for cleaning oil stains on the surface of various metal materials, and can also be used for surface cleaning of some non-metallic materials. Background technique [0002] At present, industrial metal cleaning mainly includes solvent cleaning and water-based metal cleaning agent cleaning. Solvent cleaning uses the principle of similar compatibility of organic solvents, dissolves and removes oil stains, and is divided into petroleum solvent cleaning and chlorinated hydrocarbon solvent cleaning. Solvents have high cleaning efficiency and are easy to clean oil stains on metal surfaces. They are still widely used today, but they are flammable, explosive, volatile, highly irritating to the central nervous system of the human body, and easily cause metal rust. At the same time, a large amount of ener...
