Problems solved by technology

However, water-based metal cleaning agents are prone to foaming and residues. In severe cases, the foam overflows and takes away a large amount of surfactant, which shortens the life of the cleaning agent, and the foam will reduce the cleaning efficiency.

Abstract

The invention provides a preparation method for a cleaning agent high in defoaming speed. According to the formula of the cleaning agent, the cleaning agent comprises 0.8-2.0% of anhydrous sodium metasilicate, 2-4% of an antirust agent, 2-5% of amine carboxylate, 0.5-1.0% of methylbenzotriazole, 3-5% of DissolvineH-40, 4-6% of Gemini quaternary ammonium salt C12022811, 2-5% of a foam inhibitor, 5-8% of a polyether modified organosilicone defoaming agent and the balance water, wherein a preparation method of the polyether modified organosilicone defoaming agent comprises the steps that hydrogencontaining silicone oil is prepared; mixed liquid A is prepared; synthetic reaction is conducted; and viscous solid B, that is the polyether modified organosilicone defoaming agent, is obtained. According to the preparation method, the cleaning agent is low in foam height and good in cleaning effect.

Description

technical field [0001] The invention relates to the technical field of cleaning, in particular to a preparation method of a cleaning agent with fast defoaming speed. Background technique [0002] After the metal workpiece is processed, the surface will carry dirt, such as various cutting fluids, guide rail oil, etc. If it is not cleaned, it will not only affect the smooth progress of the processing process, but also cause and accelerate the corrosion of the metal surface, affecting the processing quality and use of the product life. In addition, before finishing such as electroplating, phosphating (silanization), glaze coating, spray painting, etc., as well as in the repair and maintenance of mechanical equipment, the cleaning process is inseparable. The choice of cleaning process and the quality of the cleaning effect not only involve major issues such as safety, energy and environmental protection, but also directly affect the performance and quality of the product. There...
