Abstract

The invention relates to the technical field of cleaning agents, in particular to a metal cleaning agent, which is composed of the following raw materials in percentage by weight: 1-5% stearic acid, 1-5% citric acid, 1-5% lauric acid, bicarbonate sodium? 0.5-3%, chromic anhydride 0.5-2%, sodium silicate 0.5-2%, nonylphenol polyoxyethylene ether? 1-4%, the balance is water. The present invention adopts stearic acid, citric acid and lauric acid for compounding three kinds of different fatty acids, and the rust removal effect is good, the chromic anhydride in the raw material can effectively remove spots, and the sodium bicarbonate and sodium silicate in the raw material can both remove oil , and can prevent corrosion; the metal parts of the invention have no corrosion and no residue after being cleaned by the invention; the invention is environmentally friendly, safe, non-toxic, non-corrosive, does not pollute the environment, and is safe and stable.

Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to a metal cleaning agent. Background technique [0002] In the maintenance and repair of machining, 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. In recent years, a new type of metal cleaning agent has gradually been widely used. It can effectively replace diesel oil, kerosene and gasoline to clean parts. For example, the Chinese invention patent application with application number 201110356104.2 discloses a kind of metal cleaning agent suitable for cleaning metal. Surface metal cleaner. The present invention consists of 30-55% of surfactant; 5%-8% of cleaning aid; 7%-12% of anti-rust agent; 3%-5% of defoamer; Composition of water and other components. [0003] But the cleaning a...
