Abstract

A water-based metal cleaning agent and a preparing method thereof are disclosed. The cleaning agent includes, by weight, 15-20 parts of polyoxyethylene alkyl ether, 15-20 parts of octylphenol polyoxyethylene ether, 10-12 parts of sodium citrate, 10-12 parts of sodium stearate, 10-15 parts of sodium dodecyl sulfonate, 8-15 parts of triethanolamine oleate, 15-20 parts of coconut fatty acid diethanolamide, 3-5 parts of sodium silicate, 3-5 parts of carboxymethylcellulose, 2-4 parts of a defoamer and 80-100 parts of water. The polyoxyethylene alkyl ether, the octylphenol polyoxyethylene ether, thesodium dodecyl sulfonate are firstly dissolved into the water, then the sodium citrate, the sodium stearate, the sodium silicate, the triethanolamine oleate, the coconut fatty acid diethanolamide andthe carboxymethylcellulose are added in order according to the ratio, the mixture is stirred until the mixture is in a semitransparent state, finally the defoamer is added into the mixture, and the mixture is fully stirred. The cleaning agent is scientific and reasonable in formula, high in cleaning power, safe, environmentally friendly, simple and convenient to operate and low in cost.

Description

technical field [0001] The invention belongs to the field of industrial cleaning and relates to a metal cleaning agent, in particular to a water-based metal cleaning agent. Background technique [0002] In industrial production, whether it is the processing and assembly of parts, or heat treatment, electroplating, and product packaging and unsealing, the metal surface must be cleaned. The quality of the pre-treatment of the metal surface directly affects the bonding force between the coating or coating material and the metal base material and the integrity of the coating. At present, industrial cleaning agents can be roughly divided into water-based cleaning agents, semi-aqueous-based cleaning agents, and solvent-based cleaning agents according to their components. Among them, water-based cleaning agents have many advantages such as low cost, safety and efficiency, environmental protection, and good biodegradability, and are widely used. Water-based cleaning agents are gen...
