Environment-friendly low-temperature efficient metal cleaner

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...

Problems solved by technology

However, most of the water-based cleaning agents developed at present have similar performance, and have the following disadvantages: ①The cleaning power is not high, and the low-temperature decontamination ability is poor, and it needs to be heated above 60°C; ②There are many foams, which are not suitable for high-pressure spray washing; ③The formula It contains phosphate and nitrite substances, and most of the surfactants used are difficult to biodegrade, which is not in line with the concept of safety and environmental protection; ④Alkalinity is very strong, corrosive to metals, and there is a danger of burning the skin

As described in the patent CN1323878, although the high-efficiency metal cleaning agent has the advantages of low foaming, high efficiency, and no corrosion, the formula contains the carcinogenic sodium nitrite, which has strong toxicity; the metal cleaning agent described in the patent CN102560509A has strong cleaning performance. It can reduce corrosion and prolong the service life of metal products, but contains Na 3 PO 4 , and the cleaning temperature needs to be controlled at 50-60°C, the room temperature effect is not good, so it is not environmentally friendly and energy-saving
