Abstract

The invention discloses a low-foam metal detergent. The detergent comprises following components by weight percent: 0.3-5.0% of sodium dodecyl sulfate, 1.0-3.6% of alkylolamide, 5-8% of diethanol amine, 0.2-3.0% of zinc sulfate, 10-12% of glucolactone, 3-6% of sodium carbonate, 0.3-1.2% of dipropylene glycol ether, 0.1-0.3% of fluoro alkyl modified polysiloxane, 0.9-2.0% of sodium hydroxide and 50-79% of deionized water. The low-foam detergent has the beneficial effects that dirt on the surface of the metal is effectively cleared, and the surface of the metal is effectively protected due to the low alkaline; fluoro alkyl modified polysiloxane is used as a defoamer, so that the detergent has the characteristics that foam is low and rinsing is easy; the low-foam metal detergent contains no phosphor, is easy to degrade, and has no pollution to the water body and the environment.

Description

technical field [0001] The invention relates to a metal detergent, in particular to a low-foaming metal detergent and a preparation method thereof. Background technique [0002] In the maintenance and repair of mechanical processing, mechanical equipment, automobiles, etc., diesel oil, kerosene or gasoline are mostly used as cleaning fluids to clean parts. This not only wastes energy, but also has potential unsafe factors. If you are not careful, it may lead to a fire. Therefore, a new type of metal cleaning agent has gradually been widely used. It can well replace diesel oil, kerosene and gasoline to clean parts, and it is cheap and safe to use, and it is very suitable for mechanized cleaning operations. Metal cleaners can remove oil, grease, and dirt from the surface of metal materials without rust spots. [0003] Metal cleaning agents refer to industrial cleaning agents or oil cleaning agents used to remove oil, grease, and dirt from the surface of metal materials. Met...
