Problems solved by technology

If it is not precise, it will affect the precision of the instrument, and even cause serious problems such as damage to equipment or scrapping of processed parts.
At present, the parts are generally polished before cleaning, but the polished parts will inevitably introduce other impurities such as oil, fingerprints, and polishing abrasive particles on the surface, especially the large number of polishing abrasive particles makes the surface of the polished parts still uneven. , so the polished parts must be cleaned

Abstract

The invention discloses a special cleaning agent for a metal part and a preparation method thereof. The cleaning agent comprises coconut diethanolamide, glycerol monocaprate, oleo sarcosine octadecyl amine, 2-methyl propanesulfonic acid, glycol alkyl ether, sodium metasilicate, sodium hydroxyacetate, zinc stearate, diethyl diallyl ammonium chloride, hexamethylenetetramine, an acrylate polymer and deionized water. The preparation method comprises the following steps: firstly, pouring coconut diethanolamide, glycerol monocaprate, oleo sarcosine octadecyl amine, 2-methyl propanesulfonic acid, glycol alkyl ether and water into a stirring kettle; uniformly stirring; heating and then adding sodium metasilicate and sodium hydroxyacetate; stirring and cooling to obtain a mixture I; pouring the residual components into the stirring kettle; heating and cooling to obtain a mixture II; mixing the mixtures I and II; and heating and cooling to obtain the cleaning agent. The cleaning agent disclosed by the invention has an extremely strong cleaning performance and is free from residues, color change and corrosion pits and low in bubble.

Description

technical field [0001] The invention belongs to the technical field of metal products, and in particular relates to a special cleaning agent for metal parts and a preparation method thereof. Background technique [0002] Since the quality of metal surface pretreatment directly affects the bonding force between coating or coating materials and metal base materials and the integrity of the coating, the technical requirements for metal surface pretreatment are very strict. The metal surface after painting or pre-plating treatment should meet the following requirements: (1) No oil on the surface; (2) No excess residual foreign matter; (3) No embroidery marks and oxide film; (4) The surface reaches a certain level of roughness (5) The surface is dry, free of moisture and dust; (6) The metal matrix is ​​exposed and in an activated state. [0003] The so-called metal cleaning can be simply understood as: metal products with certain dirt in a specific solvent, using a certain proce...
